This new entry is used as a place holder for any USB device that is bootable in UEFI. The user can set the boot priority of this Generic USB Boot entry, and retain this priority for use with USB devices that might be installed in the future. Attempting to boot from the Generic USB Boot entry will result in attempting all UEFI bootable USB devices that are available in the system. The user can still control the priority of the boot entries of individual USB devices in the UEFI Boot Order list. This new Generic USB Boot entry will now be visible by default in the UEFI Boot Order after updating to this System ROM release. This new option is applicable only in UEFI Boot Mode and might be configured from the HP RESTful API or the System Utilities BIOS/Platform Configuration (RBSU). Note: The system will attempt to boot all UEFI bootable USB devices in the order of the Generic USB Boot entry even if installed individual USB devices are configured lower in the boot order. Added a new System Utilities BIOS/Platform Configuration (RBSU) Fibre Channel/FCoE Scan Policy menu that allows the user to select how the UEFI BIOS will scan for valid Fibre Channel (or boot from SAN) boot targets. By default, the system will now only scan for Fibre Channel boot targets that are configured in each adapter. In the past, the system would scan for all Fibre Channel or FCoE available targets, potentially resulting in long boot times and large number of entries in the UEFI Boot Order list. The boot targets for adapters can be configured using the adapter specific menu in the System Utilities, System Configuration menu, or using management software such as HP Virtual Connect or HP OneView. This setting is applicable only in UEFI Boot Mode. A firmware update of the fibre channel controller might also be required to take full advantage of this feature. Added a new System Utilities BIOS/Platform Configuration (RBSU) NUMA Group Size Optimizations menu that allows the user to select how the platform will report processor grouping to the operating system. For some applications which cannot optimally handle high logical processor counts that are optimally divided into smaller groups, it might be necessary to change the default setting to get optimal performance. Added a new System Utilities BIOS/Platform Configuration (RBSU) I/O Non-Posted Prefetching performance option that allows the user to configure how the chipset balances I/O traffic for PCI-e devices. Disabling this option has been shown to provide performance benefits in a very small subset of configurations including certain Infiniband configurations that require a balanced mix of read and write traffic as well as configurations with multiple x16 devices that utilize the max bandwidth of the PCI-e bus. Since disabling the option also has a negative impact on maximum I/O read bandwidth, the overwhelming majority of configurations will benefit from leaving this option at the default. Added support for Memory Mirroring Mode. This option can be selected from the Advanced Memory Protection Mode selection. This option provides enhanced memory availability and resiliency but requires additional memory be installed to achieve the same amount of memory available to the operating system. Added support for loading the Embedded UEFI Shell Auto-Startup script from the network in addition to physical/virtual media. The URL describing the network (HTTP or FTP) location of the startup script can be configured in the System Utilities /Platform Configuration (RBSU), under the Embedded Shell menu. This allows for using the Embedded UEFI Shell as a scriptable deployment environment without the need for physical or virtual media (on a bare metal system). Added support to Standard Format Output (SFO) to the SysConfig command in the Embedded UEFI Shell. This allows for easier parsing of the command output using Shell scripts. Added support for boot from URL (HTTP or FTP) functionality in UEFI Boot Mode. The network settings (DHCP or static IP) and boot file URL can be configured in the new System Utilities BIOS/Platform Configuration (RBSU) Pre-Boot Network settings menu. The file can either be a UEFI Network Boot Program (NBP), or an ISO image containing a UEFI bootable OS image. The Boot from ISO support is currently limited to operating systems that have a self contained OS image (such as WinPE, mini Linux, or VMware ESX installer). Booting Windows or Linux OS installation media is currently not supported. Added support for a webclient command in the Embedded UEFI Shell. The command can be used to download files from HTTP and FTP servers. It can also be used to download ISO CD/DVD images and mount them in memory as RAM disks. Added support for an FTP command in the Embedded UEFI Shell. The command can be used to download and upload files to/from FTP servers. Added support for a Compress command in the Embedded UEFI Shell. The command can be used to compress and decompress ZIP files. Added support for a SecBoot command in the Embedded UEFI Shell. The command can be used to display the Secure Boot keys and certificates. Enhanced the RamDisk command in the Embedded UEFI Shell to support FAT32 RAM disks, increasing the disk size limit from 512 MB to 2GB. Added support for the HP Dual 8GB MicroSD EM USB Kit. This device can be plugged into the internal USB port on the server to allow a mirrored MicroSD card solution. Added support to configure the BIOS Serial Console Baud Rate to 38400 from the System Utilities BIOS/Platform Configuration (RBSU). Added a new System Utilities BIOS/Platform Configuration (RBSU) Internal SD Card Slot menu located in USB Options that allows the user to disable boot from the embedded SD card. Added support for Intel Trusted eXecution Technology (TXT). Updated OpenSSL support to version 0.9.8zb to address potential issues that might impact the UEFI Secure Boot support. Updated the HP RESTful API HP BIOS Attribute Registry resources to match the latest BIOS/Platform Configuration options. Updated the HP RESTful API HpBiosAttributeRegistrySchema to version 1.2.0, adding support for BIOS Attributes of type "Password". Also added a new GrayOut property that can be used to describe some dependency scenarios. Also updated enumDescriptions of all enum definitions in the schema. Updated the HP RESTful API HpBios, HpServerBootSettings, HpBiosMappsings schemas to version 1.1.0. Added support for self-links in these resources. Updated the language translations (non-English modes) for System Utilities. Updated help documentation for System Utilities and the Embedded UEFI Shell. Increased timeout values in Embedded UEFI Shell IfConfig command to reduce the chances of network DHCP configuration failing due to timeouts caused by delays on the network or slow response when trying to contact the DHCP server. Enhanced the UEFI Exception handler to provide extended debug and trace information when in a pre-OS environment. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the FwUpdate Embedded Shell Application and the Firmware Update pre-boot application could hang during a firmware update and not successfully flash the device. Addressed an issue where the system might become unresponsive during boot when an unsupported memory configuration is installed on processor 2.

Addressed an issue where the system may shutdown when a fatal error occurs in the pre-OS environment (such as the System Utilities or Embedded UEFI Shell) and not log any entry into the Integrated Management Log (IML). Addressed an issue where the server would become unresponsive during boot with DIMM configurations that include both when configured with 16GB and 32GB LRDIMMs. Addressed an issue where an HP Smart Array controller installed in a PCI Express Slot attached to Processor 2 may not be visible on the first boot after the server experiences an unexpected shutdown that requires using the HP Smart Storage Battery to backup storage data. Addressed an issue where the system would continue to run (server did not perform a Blue Screen or reset as expected) when a Non Maskable Interrupt (NMI) occurs when using Microsoft Windows 2008 or Microsoft Windows 2008 R2 when Processor x2APIC Support is configured to Enabled (the default value). This issue does not impact other operating systems. Addressed an issue where optical drives were not properly reported in the server One Time Boot Menu when the HP Smart Array B140i Smart Array controller is enabled. Addressed an issue where the server could experience a Red Screen reported as a General Protection Error when a user-initiated driver recover/rebuild operation is issued to the HP Dynamic Smart Array B140i controller. Addressed a rare issue in which the user was not prompted or was not prompted correctly when exiting the UEFI System Utilities. Addressed an issue with the fwupdate Embedded UEFI Shell command that may cause the system to become unresponsive during some firmware updates. Addressed an issue with the sysconfig Embedded UEFI Shell command that may cause the system to become unresponsive when using "sysconfig -d get userdefaults all" when the user defaults have not been configured. Addressed an issue where changing the boot order using the HP RESTful Interface may result in the system not responding to key presses for F9 (System Utilities) or F11 (Boot Menu) during subsequent system boot. Addressed an issue that resulted in incorrect association of PCI devices to BIOS Attributes in the HpBiosMappings resource of the HP RESTful Interface. Addressed an issue that could cause the server's Time Zone setting to be configured to an invalid value when non-volatile storage becomes corrupted due to a battery failure. Addressed an issue where HP Smart Array error messages are not logged to the Integrated Management Log (IML). Addressed an issue that can result in an inability to access the Virtual Install Disk volume from the Embedded UEFI Shell. **Known Issues:** None - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where systems may experience one of the following conditions: A "207 - Memory Initialization Error" message and Integrated Management Log (IML) event which results from one or more DIMMs not being initialized and in which not all installed memory will be available to the operating system; a performance degradation (caused by an excessive amount of corrected memory errors but which may not have any indication that this is the cause); or a Corrected Memory Error Threshold event logged to the IML. If a system experiences any of these conditions, the System ROM should be updated to this version or later before contacting service or replacing any hardware components. **Known Issues:** None - Added support for a Generic USB Boot entry in the UEFI Boot Order list. This new entry is used as a place holder for any USB device that is bootable in UEFI. The user can set the boot priority of this Generic USB Boot entry, and retain this priority for use with USB devices that might be installed in the future. Attempting to boot from the Generic USB Boot entry will result in attempting all UEFI bootable USB devices that are available in the system. The user can still control the priority of the boot entries of individual USB devices in the UEFI Boot Order list. This new Generic USB Boot entry will now be visible by default in the UEFI Boot Order after updating to this System ROM release. This new option is applicable only in UEFI Boot Mode and might be configured from the HP RESTful API or the System Utilities BIOS/Platform Configuration (RBSU). Note: The system will attempt to boot all UEFI bootable USB devices in the order of the Generic USB Boot entry even if installed individual USB devices are configured lower in the boot order. Added a new System Utilities BIOS/Platform Configuration (RBSU) Fibre Channel/FCoE Scan Policy menu that allows the user to select how the UEFI BIOS will scan for valid Fibre Channel (or boot from SAN) boot targets. By default, the system will now only scan for Fibre Channel boot targets that are configured in each adapter. In the past, the system would scan for all Fibre Channel or FCoE available targets, potentially resulting in long boot times and large number of entries in the UEFI Boot Order list. The boot targets for adapters can be configured using the adapter specific menu in the System Utilities, System Configuration menu, or using management software such as HP Virtual Connect or HP OneView. This setting is applicable only in UEFI Boot Mode. A firmware update of the fibre channel controller might also be required to take full advantage of this feature. Added a new System Utilities BIOS/Platform Configuration (RBSU) NUMA Group Size Optimizations menu that allows the user to select how the platform will report processor grouping to the operating system. For some applications which cannot optimally handle high logical processor counts that are optimally divided into smaller groups, it might be necessary to change the default setting to get optimal performance. Added a new System Utilities BIOS/Platform Configuration (RBSU) I/O Non-Posted Prefetching performance option that allows the user to configure how the chipset balances I/O traffic for PCI-e devices. Disabling this option has been shown to provide performance benefits in a very small subset of configurations including certain Infiniband configurations that require a balanced mix of read and write traffic as well as configurations with multiple x16 devices that utilize the max bandwidth of the PCI-e bus. Since disabling the option also has a negative impact on maximum I/O read bandwidth, the overwhelming majority of configurations will benefit from leaving this option at the default. Added support for Memory Mirroring Mode. This option can be selected from the Advanced Memory Protection Mode selection. This option provides enhanced memory availability and resiliency but requires additional memory be installed to achieve the same amount of memory available to the operating system. Added support for loading the Embedded UEFI Shell Auto-Startup script from the network in addition to physical/virtual media. The URL describing the network (HTTP or FTP) location of the startup script can be configured in the System Utilities /Platform Configuration (RBSU), under the Embedded Shell menu. This allows for using the Embedded UEFI Shell as a scriptable deployment environment without the need for physical or virtual media (on a bare metal system). Added support to Standard Format Output (SFO) to the SysConfig command in the Embedded UEFI Shell. This allows for easier parsing of the command output using Shell scripts. Added support for boot from URL (HTTP or FTP) functionality in UEFI Boot Mode. The network settings (DHCP or static IP) and boot file URL can be configured in the new System Utilities BIOS/Platform Configuration (RBSU) Pre-Boot Network settings menu. The file can either be a UEFI Network Boot Program (NBP), or an ISO image containing a UEFI bootable OS image. The Boot from ISO support is currently limited to operating systems that have a self contained OS image (such as WinPE, mini Linux, or VMware ESX installer). Booting Windows or Linux OS installation media is currently not supported. Added support for a webclient command in the Embedded UEFI Shell. The command can be used to download files from HTTP and FTP servers. It can also be used to download ISO CD/DVD images and mount them in memory as RAM disks. Added support for an FTP command in the Embedded UEFI Shell. The command can be used to download and upload files to/from FTP servers. Added support for a Compress command in the Embedded UEFI Shell. The command can be used to compress and decompress ZIP files. Added support for a SecBoot command in the Embedded UEFI Shell. The command can be used to display the Secure Boot keys and certificates. Enhanced the RamDisk command in the Embedded UEFI Shell to support FAT32 RAM disks, increasing the disk size limit from 512 MB to 2GB. Added support for the HP Dual 8GB MicroSD EM USB Kit. This device can be plugged into the internal USB port on the server to allow a mirrored MicroSD card solution. Added support to configure the BIOS Serial Console Baud Rate to 38400 from the System Utilities BIOS/Platform Configuration (RBSU). Added a new System Utilities BIOS/Platform Configuration (RBSU) Internal SD Card Slot menu located in USB Options that allows the user to disable boot from the embedded SD card. Added support for Intel Trusted eXecution Technology (TXT). Updated OpenSSL support to version 0.9.8zb to address potential issues that might impact the UEFI Secure Boot support. Updated the HP RESTful API HP BIOS Attribute Registry resources to match the latest BIOS/Platform Configuration options. Updated the HP RESTful API HpBiosAttributeRegistrySchema to version 1.2.0, adding support for BIOS Attributes of type "Password". Also added a new GrayOut property that can be used to describe some dependency scenarios. Also updated enumDescriptions of all enum definitions in the schema. Updated the HP RESTful API HpBios, HpServerBootSettings, HpBiosMappsings schemas to version 1.1.0. Added support for self-links in these resources. Updated the language translations (non-English modes) for System Utilities. Updated help documentation for System Utilities and the Embedded UEFI Shell. Increased timeout values in Embedded UEFI Shell IfConfig command to reduce the chances of network DHCP configuration failing due to timeouts caused by delays on the network or slow response when trying to contact the DHCP server. Enhanced the UEFI Exception handler to provide extended debug and trace information when in a pre-OS environment. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the FwUpdate Embedded Shell Application and the Firmware Update pre-boot application could hang during a firmware update and not successfully flash the device. Addressed an issue where the system might become unresponsive during boot when an unsupported memory configuration is installed on processor 2. With this unsupported configuration, in this situation there is no user feedback on the monitor or in the Integrated Management Log (IML). With this revision of the System ROM, the system will properly display a message indicating the error and halt the boot process. Addressed an issue with some network devices name display in the System Utilities. Addressed an issue that would result in incorrect or corrupt UEFI boot order data, or malformed JSON output from the HP RESTFul API HpServerBootSettings resource. This also addresses an issue in configuring the server UEFI Boot Order using HP OneView and the HP RESTful API. Addressed an issue in accessing the file systems or booting to some RAID0 logical volumes off HP Smart Array controllers. This includes accessing the file system on such drivers in the System Utilities menus and the Embedded UEFI Shell. Addressed an issue that might result in the BIOS Console Redirection support using the Virtual Serial Port to become non-functional. Addressed an issue with incorrect system time in Microsoft Windows operating systems when booted in Legacy BIOS Boot Mode. When the system time or time zone are changed, on reboot the system time might 'jump' by the current operating system time zone offset. This issue does not occur when booting in UEFI Boot Mode. The change also removes the System Utilities BIOS/Platform Configuration (RBSU) option for ACPI RTC Support. Addressed an issue where the system might experience a Machine Check Exception under heavy stress conditions when configured with an Intel Xeon E5-2609 processor. This issue does not affect any other processor models. Addressed an issue where the server might become unresponsive after a user has repeatedly entered and incorrect Power-On or Administrator Password. Addressed an issue where the server might become unresponsive after looping through the UEFI Boot Order an extended amount of time when no valid boot targets are detected. This issue only effects the server when configured in UEFI Boot Mode. Addressed an issue where a server might not be able to properly boot Windows Server 2008 R2 when configured with an Optional Graphics Card or GPGPU. Addressed an issue where the industry standard SMBIOS tables would not properly indicate the number of active cores when Intel Hyperthreading is disabled. The number of active cores would not be reported properly by some utilities. Addressed an issue where Wake On LAN does not function if the system was shutdown prior to booting an operating system (such as during the boot process or from the Embedded UEFI Shell). Wake On LAN does function properly if the system had been shut down from an operating system. Addressed an issue where the server would boot slowly when BIOS Serial Console was enabled to the iLO Virtual Serial Port. Addressed an issue where the server could be configured for Online Spare Memory Mode when the DIMM configuration did not support this mode. Addressed an issue where a USB key was still bootable when the USB Boot Functionality was disabled from System Utilities BIOS/Platform Configuration (RBSU). This issue does not impact systems configured for UEFI Boot Mode. Address an issue where the SysConfig command from the Embedded UEFI Shell could not be used to configure Secure Boot even when the user had indicated physical presence when entering the Embedded UEFI Shell. Addressed various issues where network boot support options might not be applied properly from HP Virtual Connect or HP OneView. Addressed an issue where the Legacy Boot Order menu in the System Utilities BIOS/Platform Configuration (RBSU) might have incorrect port numbers when the server is configured in Legacy Boot Mode. This issue did not affect servers configured for UEFI Boot Mode. Addressed an issue where a server configured with a Trusted Platform Module (TPM) and Microsoft Windows 2012 R2 BitLocker might incorrectly prompt the user for a recovery password following a warm reset. Addressed an issue where messages displayed during the early boot process would not be displayed properly when viewed over BIOS Serial Console. Addressed an issue where the One Time Boot Menu includes network boot options for devices even when network boot is disabled for those devices. Addressed an issue where BIOS Serial Console redirection would not work properly when the terminal was configured in VT100+ mode and the server was configured for Legacy Boot Mode. This issue does not impact systems configured for UEFI Boot Mode. Addressed an issue where Linux dmesg might report a USB error message such as "EHCI: BIOS handoff failed" when the system was configured in Legacy Boot Mode. When this issue occurs, USB support still functions properly under the operating system and the error message is erroneous. This change only prevents the display of the erroneous message and does not impact USB functionality. Addressed several issues with the legacy USB support (USB support before the operating system loads) when the system is configured for Legacy Boot Mode. This includes addressing an issue where the system might log a 303/304 Keyboard controller failure error when certain USB KVMs are attached to the system. Addressed an issue where the SATA port numbers reported in the System Utilities BIOS/Platform Configuration (RBSU) would not properly match the port numbers reflected by labels on the system. **Known Issues:** None - Enhanced the thermal solution to provide proper cooling for optional PCIe graphics and acceleration cards. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the server may experience a high rate of corrected memory errors that result in significant performance degradation. While this issue is rare, once it occurs, the server will continue to experience a high rate of corrected errors until the server is rebooted. This issue is NOT unique to HP servers. HP recommends that users experiencing a performance issue or experiencing corrected memory error threshold events update to this revision of the System ROM before replacing any hardware components. Addressed an issue where a system running a hypervisor-based operating system may become unresponsive when a guest operating system executes certain debug commands. Addressed an issue where a system configured for UEFI Boot Mode with multiple GPUs may not be able to properly start the GPUs under the operating system.

If a system experiences any of these conditions, the System ROM should be updated to this version or later before contacting service or replacing any hardware components. **Known Issues:** None - Added support for a Generic USB Boot entry in the UEFI Boot Order list. This new entry is used as a place holder for any USB device that is bootable in UEFI. The user can set the boot priority of this Generic USB Boot entry, and retain this priority for use with USB devices that might be installed in the future. Attempting to boot from the Generic USB Boot entry will result in attempting all UEFI bootable USB devices that are available in the system. The user can still control the priority of the boot entries of individual USB devices in the UEFI Boot Order list. This new Generic USB Boot entry will now be visible by default in the UEFI Boot Order after updating to this System ROM release. This new option is applicable only in UEFI Boot Mode and might be configured from the HP RESTful API or the System Utilities BIOS/Platform Configuration (RBSU). Note: The system will attempt to boot all UEFI bootable USB devices in the order of the Generic USB Boot entry even if installed individual USB devices are configured lower in the boot order. Added a new System Utilities BIOS/Platform Configuration (RBSU) Fibre Channel/FCoE Scan Policy menu that allows the user to select how the UEFI BIOS will scan for valid Fibre Channel (or boot from SAN) boot targets. By default, the system will now only scan for Fibre Channel boot targets that are configured in each adapter. In the past, the system would scan for all Fibre Channel or FCoE available targets, potentially resulting in long boot times and large number of entries in the UEFI Boot Order list. The boot targets for adapters can be configured using the adapter specific menu in the System Utilities, System Configuration menu, or using management software such as HP Virtual Connect or HP OneView. This setting is applicable only in UEFI Boot Mode. A firmware update of the fibre channel controller might also be required to take full advantage of this feature. Added a new System Utilities BIOS/Platform Configuration (RBSU) NUMA Group Size Optimizations menu that allows the user to select how the platform will report processor grouping to the operating system. For some applications which cannot optimally handle high logical processor counts that are optimally divided into smaller groups, it might be necessary to change the default setting to get optimal performance. Added a new System Utilities BIOS/Platform Configuration (RBSU) I/O Non-Posted Prefetching performance option that allows the user to configure how the chipset balances I/O traffic for PCI-e devices. Disabling this option has been shown to provide performance benefits in a very small subset of configurations including certain Infiniband configurations that require a balanced mix of read and write traffic as well as configurations with multiple x16 devices that utilize the max bandwidth of the PCI-e bus. Since disabling the option also has a negative impact on maximum I/O read bandwidth, the overwhelming majority of configurations will benefit from leaving this option at the default. Added support for Memory Mirroring Mode. This option can be selected from the Advanced Memory Protection Mode selection. This option provides enhanced memory availability and resiliency but requires additional memory be installed to achieve the same amount of memory available to the operating system. Added support for loading the Embedded UEFI Shell Auto-Startup script from the network in addition to physical/virtual media. The URL describing the network (HTTP or FTP) location of the startup script can be configured in the System Utilities /Platform Configuration (RBSU), under the Embedded Shell menu. This allows for using the Embedded UEFI Shell as a scriptable deployment environment without the need for physical or virtual media (on a bare metal system). Added support to Standard Format Output (SFO) to the SysConfig command in the Embedded UEFI Shell. This allows for easier parsing of the command output using Shell scripts. Added support for boot from URL (HTTP or FTP) functionality in UEFI Boot Mode. The network settings (DHCP or static IP) and boot file URL can be configured in the new System Utilities BIOS/Platform Configuration (RBSU) Pre-Boot Network settings menu. The file can either be a UEFI Network Boot Program (NBP), or an ISO image containing a UEFI bootable OS image. The Boot from ISO support is currently limited to operating systems that have a self contained OS image (such as WinPE, mini Linux, or VMware ESX installer). Booting Windows or Linux OS installation media is currently not supported. Added support for a webclient command in the Embedded UEFI Shell. The command can be used to download files from HTTP and FTP servers. It can also be used to download ISO CD/DVD images and mount them in memory as RAM disks. Added support for an FTP command in the Embedded UEFI Shell. The command can be used to download and upload files to/from FTP servers. Added support for a Compress command in the Embedded UEFI Shell. The command can be used to compress and decompress ZIP files. Added support for a SecBoot command in the Embedded UEFI Shell. The command can be used to display the Secure Boot keys and certificates. Enhanced the RamDisk command in the Embedded UEFI Shell to support FAT32 RAM disks, increasing the disk size limit from 512 MB to 2GB. Added support for the HP Dual 8GB MicroSD EM USB Kit. This device can be plugged into the internal USB port on the server to allow a mirrored MicroSD card solution. Added support to configure the BIOS Serial Console Baud Rate to 38400 from the System Utilities BIOS/Platform Configuration (RBSU). Added a new System Utilities BIOS/Platform Configuration (RBSU) Internal SD Card Slot menu located in USB Options that allows the user to disable boot from the embedded SD card. Added support for Intel Trusted eXecution Technology (TXT). Updated OpenSSL support to version 0.9.8zb to address potential issues that might impact the UEFI Secure Boot support. Updated the HP RESTful API HP BIOS Attribute Registry resources to match the latest BIOS/Platform Configuration options. Updated the HP RESTful API HpBiosAttributeRegistrySchema to version 1.2.0, adding support for BIOS Attributes of type "Password". Also added a new GrayOut property that can be used to describe some dependency scenarios. Also updated enumDescriptions of all enum definitions in the schema. Updated the HP RESTful API HpBios, HpServerBootSettings, HpBiosMappsings schemas to version 1.1.0. Added support for self-links in these resources. Updated the language translations (non-English modes) for System Utilities. Updated help documentation for System Utilities and the Embedded UEFI Shell. Increased timeout values in Embedded UEFI Shell IfConfig command to reduce the chances of network DHCP configuration failing due to timeouts caused by delays on the network or slow response when trying to contact the DHCP server. Enhanced the UEFI Exception handler to provide extended debug and trace information when in a pre-OS environment. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the FwUpdate Embedded Shell Application and the Firmware Update pre-boot application could hang during a firmware update and not successfully flash the device. Addressed an issue where the system might become unresponsive during boot when an unsupported memory configuration is installed on processor 2. With this unsupported configuration, in this situation there is no user feedback on the monitor or in the Integrated Management Log (IML). With this revision of the System ROM, the system will properly display a message indicating the error and halt the boot process. Addressed an issue with some network devices name display in the System Utilities. Addressed an issue that would result in incorrect or corrupt UEFI boot order data, or malformed JSON output from the HP RESTFul API HpServerBootSettings resource. This also addresses an issue in configuring the server UEFI Boot Order using HP OneView and the HP RESTful API. Addressed an issue in accessing the file systems or booting to some RAID0 logical volumes off HP Smart Array controllers. This includes accessing the file system on such drivers in the System Utilities menus and the Embedded UEFI Shell. Addressed an issue that might result in the BIOS Console Redirection support using the Virtual Serial Port to become non-functional. Addressed an issue with incorrect system time in Microsoft Windows operating systems when booted in Legacy BIOS Boot Mode. When the system time or time zone are changed, on reboot the system time might 'jump' by the current operating system time zone offset. This issue does not occur when booting in UEFI Boot Mode. The change also removes the System Utilities BIOS/Platform Configuration (RBSU) option for ACPI RTC Support. Addressed an issue where the system might experience a Machine Check Exception under heavy stress conditions when configured with an Intel Xeon E5-2609 processor. This issue does not affect any other processor models. Addressed an issue where the server might become unresponsive after a user has repeatedly entered and incorrect Power-On or Administrator Password. Addressed an issue where the server might become unresponsive after looping through the UEFI Boot Order an extended amount of time when no valid boot targets are detected.

If a system experiences any of these conditions, the System ROM should be updated to this version or later before contacting service or replacing any hardware components. **Known Issues:** None - Added support for a Generic USB Boot entry in the UEFI Boot Order list. This new entry is used as a place holder for any USB device that is bootable in UEFI. The user can set the boot priority of this Generic USB Boot entry, and retain this priority for use with USB devices that might be installed in the future. Attempting to boot from the Generic USB Boot entry will result in attempting all UEFI bootable USB devices that are available in the system. The user can still control the priority of the boot entries of individual USB devices in the UEFI Boot Order list. This new Generic USB Boot entry will now be visible by default in the UEFI Boot Order after updating to this System ROM release. This new option is applicable only in UEFI Boot Mode and might be configured from the HP RESTful API or the System Utilities BIOS/Platform Configuration (RBSU). Note: The system will attempt to boot all UEFI bootable USB devices in the order of the Generic USB Boot entry even if installed individual USB devices are configured lower in the boot order. Added a new System Utilities BIOS/Platform Configuration (RBSU) Fibre Channel/FCoE Scan Policy menu that allows the user to select how the UEFI BIOS will scan for valid Fibre Channel (or boot from SAN) boot targets. By default, the system will now only scan for Fibre Channel boot targets that are configured in each adapter. In the past, the system would scan for all Fibre Channel or FCoE available targets, potentially resulting in long boot times and large number of entries in the UEFI Boot Order list. The boot targets for adapters can be configured using the adapter specific menu in the System Utilities, System Configuration menu, or using management software such as HP Virtual Connect or HP OneView. This setting is applicable only in UEFI Boot Mode. A firmware update of the fibre channel controller might also be required to take full advantage of this feature. Added a new System Utilities BIOS/Platform Configuration (RBSU) NUMA Group Size Optimizations menu that allows the user to select how the platform will report processor grouping to the operating system. For some applications which cannot optimally handle high logical processor counts that are optimally divided into smaller groups, it might be necessary to change the default setting to get optimal performance. Added a new System Utilities BIOS/Platform Configuration (RBSU) I/O Non-Posted Prefetching performance option that allows the user to configure how the chipset balances I/O traffic for PCI-e devices. Disabling this option has been shown to provide performance benefits in a very small subset of configurations including certain Infiniband configurations that require a balanced mix of read and write traffic as well as configurations with multiple x16 devices that utilize the max bandwidth of the PCI-e bus. Since disabling the option also has a negative impact on maximum I/O read bandwidth, the overwhelming majority of configurations will benefit from leaving this option at the default. Added support for Memory Mirroring Mode. This option can be selected from the Advanced Memory Protection Mode selection. This option provides enhanced memory availability and resiliency but requires additional memory be installed to achieve the same amount of memory available to the operating system. Added support for loading the Embedded UEFI Shell Auto-Startup script from the network in addition to physical/virtual media. The URL describing the network (HTTP or FTP) location of the startup script can be configured in the System Utilities /Platform Configuration (RBSU), under the Embedded Shell menu. This allows for using the Embedded UEFI Shell as a scriptable deployment environment without the need for physical or virtual media (on a bare metal system). Added support to Standard Format Output (SFO) to the SysConfig command in the Embedded UEFI Shell. This allows for easier parsing of the command output using Shell scripts. Added support for boot from URL (HTTP or FTP) functionality in UEFI Boot Mode. The network settings (DHCP or static IP) and boot file URL can be configured in the new System Utilities BIOS/Platform Configuration (RBSU) Pre-Boot Network settings menu. The file can either be a UEFI Network Boot Program (NBP), or an ISO image containing a UEFI bootable OS image. The Boot from ISO support is currently limited to operating systems that have a self contained OS image (such as WinPE, mini Linux, or VMware ESX installer). Booting Windows or Linux OS installation media is currently not supported. Added support for a webclient command in the Embedded UEFI Shell. The command can be used to download files from HTTP and FTP servers. It can also be used to download ISO CD/DVD images and mount them in memory as RAM disks. Added support for an FTP command in the Embedded UEFI Shell. The command can be used to download and upload files to/from FTP servers. Added support for a Compress command in the Embedded UEFI Shell. The command can be used to compress and decompress ZIP files. Added support for a SecBoot command in the Embedded UEFI Shell. The command can be used to display the Secure Boot keys and certificates. Enhanced the RamDisk command in the Embedded UEFI Shell to support FAT32 RAM disks, increasing the disk size limit from 512 MB to 2GB. Added support for the HP Dual 8GB MicroSD EM USB Kit. This device can be plugged into the internal USB port on the server to allow a mirrored MicroSD card solution. Added support to configure the BIOS Serial Console Baud Rate to 38400 from the System Utilities BIOS/Platform Configuration (RBSU). Added a new System Utilities BIOS/Platform Configuration (RBSU) Internal SD Card Slot menu located in USB Options that allows the user to disable boot from the embedded SD card. Added support for Intel Trusted eXecution Technology (TXT). Updated OpenSSL support to version 0.9.8zb to address potential issues that might impact the UEFI Secure Boot support. Updated the HP RESTful API HP BIOS Attribute Registry resources to match the latest BIOS/Platform Configuration options. Updated the HP RESTful API HpBiosAttributeRegistrySchema to version 1.2.0, adding support for BIOS Attributes of type "Password". Also added a new GrayOut property that can be used to describe some dependency scenarios. Also updated enumDescriptions of all enum definitions in the schema. Updated the HP RESTful API HpBios, HpServerBootSettings, HpBiosMappsings schemas to version 1.1.0. Added support for self-links in these resources. Updated the language translations (non-English modes) for System Utilities. Updated help documentation for System Utilities and the Embedded UEFI Shell. Increased timeout values in Embedded UEFI Shell IfConfig command to reduce the chances of network DHCP configuration failing due to timeouts caused by delays on the network or slow response when trying to contact the DHCP server. Enhanced the UEFI Exception handler to provide extended debug and trace information when in a pre-OS environment. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the FwUpdate Embedded Shell Application and the Firmware Update pre-boot application could hang during a firmware update and not successfully flash the device.

If a system experiences any of these conditions, the System ROM should be updated to this version or later before contacting service or replacing any hardware components. **Known Issues:** None - Added support for a Generic USB Boot entry in the UEFI Boot Order list. This new entry is used as a place holder for any USB device that is bootable in UEFI. The user can set the boot priority of this Generic USB Boot entry, and retain this priority for use with USB devices that might be installed in the future. Attempting to boot from the Generic USB Boot entry will result in attempting all UEFI bootable USB devices that are available in the system. The user can still control the priority of the boot entries of individual USB devices in the UEFI Boot Order list. This new Generic USB Boot entry will now be visible by default in the UEFI Boot Order after updating to this System ROM release. This new option is applicable only in UEFI Boot Mode and might be configured from the HP RESTful API or the System Utilities BIOS/Platform Configuration (RBSU). Note: The system will attempt to boot all UEFI bootable USB devices in the order of the Generic USB Boot entry even if installed individual USB devices are configured lower in the boot order. Added a new System Utilities BIOS/Platform Configuration (RBSU) Fibre Channel/FCoE Scan Policy menu that allows the user to select how the UEFI BIOS will scan for valid Fibre Channel (or boot from SAN) boot targets. By default, the system will now only scan for Fibre Channel boot targets that are configured in each adapter. In the past, the system would scan for all Fibre Channel or FCoE available targets, potentially resulting in long boot times and large number of entries in the UEFI Boot Order list. The boot targets for adapters can be configured using the adapter specific menu in the System Utilities, System Configuration menu, or using management software such as HP Virtual Connect or HP OneView. This setting is applicable only in UEFI Boot Mode. A firmware update of the fibre channel controller might also be required to take full advantage of this feature. Added a new System Utilities BIOS/Platform Configuration (RBSU) NUMA Group Size Optimizations menu that allows the user to select how the platform will report processor grouping to the operating system. For some applications which cannot optimally handle high logical processor counts that are optimally divided into smaller groups, it might be necessary to change the default setting to get optimal performance. Added a new System Utilities BIOS/Platform Configuration (RBSU) I/O Non-Posted Prefetching performance option that allows the user to configure how the chipset balances I/O traffic for PCI-e devices. Disabling this option has been shown to provide performance benefits in a very small subset of configurations including certain Infiniband configurations that require a balanced mix of read and write traffic as well as configurations with multiple x16 devices that utilize the max bandwidth of the PCI-e bus. Since disabling the option also has a negative impact on maximum I/O read bandwidth, the overwhelming majority of configurations will benefit from leaving this option at the default. Added support for Memory Mirroring Mode. This option can be selected from the Advanced Memory Protection Mode selection. This option provides enhanced memory availability and resiliency but requires additional memory be installed to achieve the same amount of memory available to the operating system. Added support for loading the Embedded UEFI Shell Auto-Startup script from the network in addition to physical/virtual media. The URL describing the network (HTTP or FTP) location of the startup script can be configured in the System Utilities /Platform Configuration (RBSU), under the Embedded Shell menu. This allows for using the Embedded UEFI Shell as a scriptable deployment environment without the need for physical or virtual media (on a bare metal system). Added support to Standard Format Output (SFO) to the SysConfig command in the Embedded UEFI Shell. This allows for easier parsing of the command output using Shell scripts. Added support for boot from URL (HTTP or FTP) functionality in UEFI Boot Mode. The network settings (DHCP or static IP) and boot file URL can be configured in the new System Utilities BIOS/Platform Configuration (RBSU) Pre-Boot Network settings menu. The file can either be a UEFI Network Boot Program (NBP), or an ISO image containing a UEFI bootable OS image. The Boot from ISO support is currently limited to operating systems that have a self contained OS image (such as WinPE, mini Linux, or VMware ESX installer). Booting Windows or Linux OS installation media is currently not supported. Added support for a webclient command in the Embedded UEFI Shell. The command can be used to download files from HTTP and FTP servers. It can also be used to download ISO CD/DVD images and mount them in memory as RAM disks. Added support for an FTP command in the Embedded UEFI Shell. The command can be used to download and upload files to/from FTP servers. Added support for a Compress command in the Embedded UEFI Shell. The command can be used to compress and decompress ZIP files. Added support for a SecBoot command in the Embedded UEFI Shell. The command can be used to display the Secure Boot keys and certificates. Enhanced the RamDisk command in the Embedded UEFI Shell to support FAT32 RAM disks, increasing the disk size limit from 512 MB to 2GB. Added support for the HP Dual 8GB MicroSD EM USB Kit. This device can be plugged into the internal USB port on the server to allow a mirrored MicroSD card solution. Added support to configure the BIOS Serial Console Baud Rate to 38400 from the System Utilities BIOS/Platform Configuration (RBSU). Added a new System Utilities BIOS/Platform Configuration (RBSU) Internal SD Card Slot menu located in USB Options that allows the user to disable boot from the embedded SD card. Added support for Intel Trusted eXecution Technology (TXT). Updated OpenSSL support to version 0.9.8zb to address potential issues that might impact the UEFI Secure Boot support. Updated the HP RESTful API HP BIOS Attribute Registry resources to match the latest BIOS/Platform Configuration options. Updated the HP RESTful API HpBiosAttributeRegistrySchema to version 1.2.0, adding support for BIOS Attributes of type "Password". Also added a new GrayOut property that can be used to describe some dependency scenarios. Also updated enumDescriptions of all enum definitions in the schema. Updated the HP RESTful API HpBios, HpServerBootSettings, HpBiosMappsings schemas to version 1.1.0. Added support for self-links in these resources. Updated the language translations (non-English modes) for System Utilities. Updated help documentation for System Utilities and the Embedded UEFI Shell. Increased timeout values in Embedded UEFI Shell IfConfig command to reduce the chances of network DHCP configuration failing due to timeouts caused by delays on the network or slow response when trying to contact the DHCP server. Enhanced the UEFI Exception handler to provide extended debug and trace information when in a pre-OS environment. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the FwUpdate Embedded Shell Application and the Firmware Update pre-boot application could hang during a firmware update and not successfully flash the device.

If a system experiences any of these conditions, the System ROM should be updated to this version or later before contacting service or replacing any hardware components. **Known Issues:** None - Added support for a Generic USB Boot entry in the UEFI Boot Order list. This new entry is used as a place holder for any USB device that is bootable in UEFI. The user can set the boot priority of this Generic USB Boot entry, and retain this priority for use with USB devices that might be installed in the future. Attempting to boot from the Generic USB Boot entry will result in attempting all UEFI bootable USB devices that are available in the system. The user can still control the priority of the boot entries of individual USB devices in the UEFI Boot Order list. This new Generic USB Boot entry will now be visible by default in the UEFI Boot Order after updating to this System ROM release. This new option is applicable only in UEFI Boot Mode and might be configured from the HP RESTful API or the System Utilities BIOS/Platform Configuration (RBSU). Note: The system will attempt to boot all UEFI bootable USB devices in the order of the Generic USB Boot entry even if installed individual USB devices are configured lower in the boot order. Added a new System Utilities BIOS/Platform Configuration (RBSU) Fibre Channel/FCoE Scan Policy menu that allows the user to select how the UEFI BIOS will scan for valid Fibre Channel (or boot from SAN) boot targets. By default, the system will now only scan for Fibre Channel boot targets that are configured in each adapter. In the past, the system would scan for all Fibre Channel or FCoE available targets, potentially resulting in long boot times and large number of entries in the UEFI Boot Order list. The boot targets for adapters can be configured using the adapter specific menu in the System Utilities, System Configuration menu, or using management software such as HP Virtual Connect or HP OneView. This setting is applicable only in UEFI Boot Mode. A firmware update of the fibre channel controller might also be required to take full advantage of this feature. Added a new System Utilities BIOS/Platform Configuration (RBSU) NUMA Group Size Optimizations menu that allows the user to select how the platform will report processor grouping to the operating system. For some applications which cannot optimally handle high logical processor counts that are optimally divided into smaller groups, it might be necessary to change the default setting to get optimal performance. Added a new System Utilities BIOS/Platform Configuration (RBSU) I/O Non-Posted Prefetching performance option that allows the user to configure how the chipset balances I/O traffic for PCI-e devices. Disabling this option has been shown to provide performance benefits in a very small subset of configurations including certain Infiniband configurations that require a balanced mix of read and write traffic as well as configurations with multiple x16 devices that utilize the max bandwidth of the PCI-e bus. Since disabling the option also has a negative impact on maximum I/O read bandwidth, the overwhelming majority of configurations will benefit from leaving this option at the default. Added support for Memory Mirroring Mode. This option can be selected from the Advanced Memory Protection Mode selection. This option provides enhanced memory availability and resiliency but requires additional memory be installed to achieve the same amount of memory available to the operating system. Added support for loading the Embedded UEFI Shell Auto-Startup script from the network in addition to physical/virtual media. The URL describing the network (HTTP or FTP) location of the startup script can be configured in the System Utilities /Platform Configuration (RBSU), under the Embedded Shell menu. This allows for using the Embedded UEFI Shell as a scriptable deployment environment without the need for physical or virtual media (on a bare metal system). Added support to Standard Format Output (SFO) to the SysConfig command in the Embedded UEFI Shell. This allows for easier parsing of the command output using Shell scripts. Added support for boot from URL (HTTP or FTP) functionality in UEFI Boot Mode. The network settings (DHCP or static IP) and boot file URL can be configured in the new System Utilities BIOS/Platform Configuration (RBSU) Pre-Boot Network settings menu. The file can either be a UEFI Network Boot Program (NBP), or an ISO image containing a UEFI bootable OS image. The Boot from ISO support is currently limited to operating systems that have a self contained OS image (such as WinPE, mini Linux, or VMware ESX installer). Booting Windows or Linux OS installation media is currently not supported. Added support for a webclient command in the Embedded UEFI Shell. The command can be used to download files from HTTP and FTP servers. It can also be used to download ISO CD/DVD images and mount them in memory as RAM disks. Added support for an FTP command in the Embedded UEFI Shell. The command can be used to download and upload files to/from FTP servers. Added support for a Compress command in the Embedded UEFI Shell. The command can be used to compress and decompress ZIP files. Added support for a SecBoot command in the Embedded UEFI Shell. The command can be used to display the Secure Boot keys and certificates. Enhanced the RamDisk command in the Embedded UEFI Shell to support FAT32 RAM disks, increasing the disk size limit from 512 MB to 2GB. Added support for the HP Dual 8GB MicroSD EM USB Kit. This device can be plugged into the internal USB port on the server to allow a mirrored MicroSD card solution. Added support to configure the BIOS Serial Console Baud Rate to 38400 from the System Utilities BIOS/Platform Configuration (RBSU). Added a new System Utilities BIOS/Platform Configuration (RBSU) Internal SD Card Slot menu located in USB Options that allows the user to disable boot from the embedded SD card. Added support for Intel Trusted eXecution Technology (TXT). Updated OpenSSL support to version 0.9.8zb to address potential issues that might impact the UEFI Secure Boot support. Updated the HP RESTful API HP BIOS Attribute Registry resources to match the latest BIOS/Platform Configuration options. Updated the HP RESTful API HpBiosAttributeRegistrySchema to version 1.2.0, adding support for BIOS Attributes of type "Password". Also added a new GrayOut property that can be used to describe some dependency scenarios. Also updated enumDescriptions of all enum definitions in the schema. Updated the HP RESTful API HpBios, HpServerBootSettings, HpBiosMappsings schemas to version 1.1.0. Added support for self-links in these resources. Updated the language translations (non-English modes) for System Utilities. Updated help documentation for System Utilities and the Embedded UEFI Shell. Increased timeout values in Embedded UEFI Shell IfConfig command to reduce the chances of network DHCP configuration failing due to timeouts caused by delays on the network or slow response when trying to contact the DHCP server. Enhanced the UEFI Exception handler to provide extended debug and trace information when in a pre-OS environment. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the FwUpdate Embedded Shell Application and the Firmware Update pre-boot application could hang during a firmware update and not successfully flash the device.

If a system experiences any of these conditions, the System ROM should be updated to this version or later before contacting service or replacing any hardware components. **Known Issues:** None - Added support for a Generic USB Boot entry in the UEFI Boot Order list. This new entry is used as a place holder for any USB device that is bootable in UEFI. The user can set the boot priority of this Generic USB Boot entry, and retain this priority for use with USB devices that might be installed in the future. Attempting to boot from the Generic USB Boot entry will result in attempting all UEFI bootable USB devices that are available in the system. The user can still control the priority of the boot entries of individual USB devices in the UEFI Boot Order list. This new Generic USB Boot entry will now be visible by default in the UEFI Boot Order after updating to this System ROM release. This new option is applicable only in UEFI Boot Mode and might be configured from the HP RESTful API or the System Utilities BIOS/Platform Configuration (RBSU). Note: The system will attempt to boot all UEFI bootable USB devices in the order of the Generic USB Boot entry even if installed individual USB devices are configured lower in the boot order. Added a new System Utilities BIOS/Platform Configuration (RBSU) Fibre Channel/FCoE Scan Policy menu that allows the user to select how the UEFI BIOS will scan for valid Fibre Channel (or boot from SAN) boot targets. By default, the system will now only scan for Fibre Channel boot targets that are configured in each adapter. In the past, the system would scan for all Fibre Channel or FCoE available targets, potentially resulting in long boot times and large number of entries in the UEFI Boot Order list. The boot targets for adapters can be configured using the adapter specific menu in the System Utilities, System Configuration menu, or using management software such as HP Virtual Connect or HP OneView. This setting is applicable only in UEFI Boot Mode. A firmware update of the fibre channel controller might also be required to take full advantage of this feature. Added a new System Utilities BIOS/Platform Configuration (RBSU) NUMA Group Size Optimizations menu that allows the user to select how the platform will report processor grouping to the operating system. For some applications which cannot optimally handle high logical processor counts that are optimally divided into smaller groups, it might be necessary to change the default setting to get optimal performance. Added a new System Utilities BIOS/Platform Configuration (RBSU) I/O Non-Posted Prefetching performance option that allows the user to configure how the chipset balances I/O traffic for PCI-e devices. Disabling this option has been shown to provide performance benefits in a very small subset of configurations including certain Infiniband configurations that require a balanced mix of read and write traffic as well as configurations with multiple x16 devices that utilize the max bandwidth of the PCI-e bus. Since disabling the option also has a negative impact on maximum I/O read bandwidth, the overwhelming majority of configurations will benefit from leaving this option at the default. Added support for Memory Mirroring Mode. This option can be selected from the Advanced Memory Protection Mode selection. This option provides enhanced memory availability and resiliency but requires additional memory be installed to achieve the same amount of memory available to the operating system. Added support for loading the Embedded UEFI Shell Auto-Startup script from the network in addition to physical/virtual media. The URL describing the network (HTTP or FTP) location of the startup script can be configured in the System Utilities /Platform Configuration (RBSU), under the Embedded Shell menu. This allows for using the Embedded UEFI Shell as a scriptable deployment environment without the need for physical or virtual media (on a bare metal system). Added support to Standard Format Output (SFO) to the SysConfig command in the Embedded UEFI Shell. This allows for easier parsing of the command output using Shell scripts. Added support for boot from URL (HTTP or FTP) functionality in UEFI Boot Mode. The network settings (DHCP or static IP) and boot file URL can be configured in the new System Utilities BIOS/Platform Configuration (RBSU) Pre-Boot Network settings menu. The file can either be a UEFI Network Boot Program (NBP), or an ISO image containing a UEFI bootable OS image. The Boot from ISO support is currently limited to operating systems that have a self contained OS image (such as WinPE, mini Linux, or VMware ESX installer). Booting Windows or Linux OS installation media is currently not supported. Added support for a webclient command in the Embedded UEFI Shell. The command can be used to download files from HTTP and FTP servers. It can also be used to download ISO CD/DVD images and mount them in memory as RAM disks. Added support for an FTP command in the Embedded UEFI Shell. The command can be used to download and upload files to/from FTP servers. Added support for a Compress command in the Embedded UEFI Shell. The command can be used to compress and decompress ZIP files. Added support for a SecBoot command in the Embedded UEFI Shell. The command can be used to display the Secure Boot keys and certificates. Enhanced the RamDisk command in the Embedded UEFI Shell to support FAT32 RAM disks, increasing the disk size limit from 512 MB to 2GB. Added support for the HP Dual 8GB MicroSD EM USB Kit. This device can be plugged into the internal USB port on the server to allow a mirrored MicroSD card solution. Added support to configure the BIOS Serial Console Baud Rate to 38400 from the System Utilities BIOS/Platform Configuration (RBSU). Added a new System Utilities BIOS/Platform Configuration (RBSU) Internal SD Card Slot menu located in USB Options that allows the user to disable boot from the embedded SD card. Added support for Intel Trusted eXecution Technology (TXT). Updated OpenSSL support to version 0.9.8zb to address potential issues that might impact the UEFI Secure Boot support. Updated the HP RESTful API HP BIOS Attribute Registry resources to match the latest BIOS/Platform Configuration options. Updated the HP RESTful API HpBiosAttributeRegistrySchema to version 1.2.0, adding support for BIOS Attributes of type "Password". Also added a new GrayOut property that can be used to describe some dependency scenarios. Also updated enumDescriptions of all enum definitions in the schema. Updated the HP RESTful API HpBios, HpServerBootSettings, HpBiosMappsings schemas to version 1.1.0. Added support for self-links in these resources. Updated the language translations (non-English modes) for System Utilities. Updated help documentation for System Utilities and the Embedded UEFI Shell. Increased timeout values in Embedded UEFI Shell IfConfig command to reduce the chances of network DHCP configuration failing due to timeouts caused by delays on the network or slow response when trying to contact the DHCP server. Enhanced the UEFI Exception handler to provide extended debug and trace information when in a pre-OS environment. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the FwUpdate Embedded Shell Application and the Firmware Update pre-boot application could hang during a firmware update and not successfully flash the device. Addressed an issue where the system might become unresponsive during boot when an unsupported memory configuration is installed on processor 2. With this unsupported configuration, in this situation there is no user feedback on the monitor or in the Integrated Management Log (IML). With this revision of the System ROM, the system will properly display a message indicating the error and halt the boot process. Addressed an issue with some network devices name display in the System Utilities. Addressed an issue that would result in incorrect or corrupt UEFI boot order data, or malformed JSON output from the HP RESTFul API HpServerBootSettings resource. This also addresses an issue in configuring the server UEFI Boot Order using HP OneView and the HP RESTful API. Addressed an issue in accessing the file systems or booting to some RAID0 logical volumes off HP Smart Array controllers. This includes accessing the file system on such drivers in the System Utilities menus and the Embedded UEFI Shell. Addressed an issue that might result in the BIOS Console Redirection support using the Virtual Serial Port to become non-functional. Addressed an issue with incorrect system time in Microsoft Windows operating systems when booted in Legacy BIOS Boot Mode. When the system time or time zone are changed, on reboot the system time might 'jump' by the current operating system time zone offset. This issue does not occur when booting in UEFI Boot Mode. The change also removes the System Utilities BIOS/Platform Configuration (RBSU) option for ACPI RTC Support. Addressed an issue where the system might experience a Machine Check Exception under heavy stress conditions when configured with an Intel Xeon E5-2609 processor. This issue does not affect any other processor models.

Addressed various issues where network boot support options might not be applied properly from HP Virtual Connect or HP OneView. Addressed an issue where the Legacy Boot Order menu in the System Utilities BIOS/Platform Configuration (RBSU) might have incorrect port numbers when the server is configured in Legacy Boot Mode. This issue did not affect servers configured for UEFI Boot Mode. Addressed an issue where a server configured with a Trusted Platform Module (TPM) and Microsoft Windows 2012 R2 BitLocker might incorrectly prompt the user for a recovery password following a warm reset. Addressed an issue where messages displayed during the early boot process would not be displayed properly when viewed over BIOS Serial Console. Addressed an issue where the One Time Boot Menu includes network boot options for devices even when network boot is disabled for those devices. Addressed an issue where BIOS Serial Console redirection would not work properly when the terminal was configured in VT100+ mode and the server was configured for Legacy Boot Mode. This issue does not impact systems configured for UEFI Boot Mode. Addressed an issue where Linux dmesg might report a USB error message such as "EHCI: BIOS handoff failed" when the system was configured in Legacy Boot Mode. When this issue occurs, USB support still functions properly under the operating system and the error message is erroneous. This change only prevents the display of the erroneous message and does not impact USB functionality. Addressed several issues with the legacy USB support (USB support before the operating system loads) when the system is configured for Legacy Boot Mode. This includes addressing an issue where the system might log a 303/304 Keyboard controller failure error when certain USB KVMs are attached to the system. Addressed an issue where the SATA port numbers reported in the System Utilities BIOS/Platform Configuration (RBSU) would not properly match the port numbers reflected by labels on the system. **Known Issues:** None - Enhanced the thermal solution to provide proper cooling for optional PCIe graphics and acceleration cards. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the server may experience a high rate of corrected memory errors that result in significant performance degradation.

When this issue occurs, the Integrated Management Log (IML) will not have any indication of the error. Addressed an issue where the Administrator Password and Power-On Password were incorrectly allowed to be entered with a length of 32 characters with previous revisions of the System ROM. These passwords should support a maximum length of 31 characters. If a 32 character Administrator Password or Power-On Password had been configured in the server, updating to this revision of the System ROM will no longer allow entering these passwords. In this case, the user must set Switch 5 to the ON position to disable these passwords. The Administrator Password and Power-On Password must then be re-entered into the system with a maximum length of 31 characters. Addressed a rare intermittent issue where the F10 prompt to enter Intelligent Provisioning is not displayed. Note that the Integrated Lights-Out (iLO) Firmware had a similar issue. To address all cases of the F10 prompt not being displayed, also update the iLO Firmware to revision 2.02. Addressed an issue where selecting "Erase User Defaults" (to erase user defined defaults) in BIOS/Platform Configuration (RBSU) does not take effect if the user also selected Restore Default System Settings or Restore Default Manufacturing Settings. Addressed an issue where the Integrated Management Log (IML) or operating system log would report multiple error entries when an Non-Maskable Interrupt (NMI) occurs. Addressed an issue where the system may shutdown when a fatal error occurs in the pre-OS environment (such as the System Utilities or Embedded UEFI Shell) and not log any entry into the Integrated Management Log (IML). Addressed an issue where the server would become unresponsive during boot with DIMM configurations that include both when configured with 16GB and 32GB LRDIMMs. Addressed an issue where an HP Smart Array controller installed in a PCI Express Slot attached to Processor 2 may not be visible on the first boot after the server experiences an unexpected shutdown that requires using the HP Smart Storage Battery to backup storage data. Addressed an issue where the system would continue to run (server did not perform a Blue Screen or reset as expected) when a Non Maskable Interrupt (NMI) occurs when using Microsoft Windows 2008 or Microsoft Windows 2008 R2 when Processor x2APIC Support is configured to Enabled (the default value). This issue does not impact other operating systems. Addressed an issue where optical drives were not properly reported in the server One Time Boot Menu when the HP Smart Array B140i Smart Array controller is enabled. Addressed an issue where the server could experience a Red Screen reported as a General Protection Error when a user-initiated driver recover/rebuild operation is issued to the HP Dynamic Smart Array B140i controller. Addressed a rare issue in which the user was not prompted or was not prompted correctly when exiting the UEFI System Utilities. Addressed an issue with the fwupdate Embedded UEFI Shell command that may cause the system to become unresponsive during some firmware updates. Addressed an issue with the sysconfig Embedded UEFI Shell command that may cause the system to become unresponsive when using "sysconfig -d get userdefaults all" when the user defaults have not been configured. Addressed an issue where changing the boot order using the HP RESTful Interface may result in the system not responding to key presses for F9 (System Utilities) or F11 (Boot Menu) during subsequent system boot. Addressed an issue that resulted in incorrect association of PCI devices to BIOS Attributes in the HpBiosMappings resource of the HP RESTful Interface. Addressed an issue that could cause the server's Time Zone setting to be configured to an invalid value when non-volatile storage becomes corrupted due to a battery failure. Addressed an issue where HP Smart Array error messages are not logged to the Integrated Management Log (IML). Addressed an issue that can result in an inability to access the Virtual Install Disk volume from the Embedded UEFI Shell. **Known Issues:** None - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where systems may experience one of the following conditions: A "207 - Memory Initialization Error" message and Integrated Management Log (IML) event which results from one or more DIMMs not being initialized and in which not all installed memory will be available to the operating system; a performance degradation (caused by an excessive amount of corrected memory errors but which may not have any indication that this is the cause); or a Corrected Memory Error Threshold event logged to the IML. If a system experiences any of these conditions, the System ROM should be updated to this version or later before contacting service or replacing any hardware components. **Known Issues:** None - Added support for a Generic USB Boot entry in the UEFI Boot Order list. This new entry is used as a place holder for any USB device that is bootable in UEFI. The user can set the boot priority of this Generic USB Boot entry, and retain this priority for use with USB devices that might be installed in the future. Attempting to boot from the Generic USB Boot entry will result in attempting all UEFI bootable USB devices that are available in the system. The user can still control the priority of the boot entries of individual USB devices in the UEFI Boot Order list. This new Generic USB Boot entry will now be visible by default in the UEFI Boot Order after updating to this System ROM release. This new option is applicable only in UEFI Boot Mode and might be configured from the HP RESTful API or the System Utilities BIOS/Platform Configuration (RBSU). Note: The system will attempt to boot all UEFI bootable USB devices in the order of the Generic USB Boot entry even if installed individual USB devices are configured lower in the boot order. Added a new System Utilities BIOS/Platform Configuration (RBSU) Fibre Channel/FCoE Scan Policy menu that allows the user to select how the UEFI BIOS will scan for valid Fibre Channel (or boot from SAN) boot targets. By default, the system will now only scan for Fibre Channel boot targets that are configured in each adapter. In the past, the system would scan for all Fibre Channel or FCoE available targets, potentially resulting in long boot times and large number of entries in the UEFI Boot Order list. The boot targets for adapters can be configured using the adapter specific menu in the System Utilities, System Configuration menu, or using management software such as HP Virtual Connect or HP OneView. This setting is applicable only in UEFI Boot Mode. A firmware update of the fibre channel controller might also be required to take full advantage of this feature. Added a new System Utilities BIOS/Platform Configuration (RBSU) NUMA Group Size Optimizations menu that allows the user to select how the platform will report processor grouping to the operating system. For some applications which cannot optimally handle high logical processor counts that are optimally divided into smaller groups, it might be necessary to change the default setting to get optimal performance. Added a new System Utilities BIOS/Platform Configuration (RBSU) I/O Non-Posted Prefetching performance option that allows the user to configure how the chipset balances I/O traffic for PCI-e devices. Disabling this option has been shown to provide performance benefits in a very small subset of configurations including certain Infiniband configurations that require a balanced mix of read and write traffic as well as configurations with multiple x16 devices that utilize the max bandwidth of the PCI-e bus. Since disabling the option also has a negative impact on maximum I/O read bandwidth, the overwhelming majority of configurations will benefit from leaving this option at the default. Added support for Memory Mirroring Mode. This option can be selected from the Advanced Memory Protection Mode selection. This option provides enhanced memory availability and resiliency but requires additional memory be installed to achieve the same amount of memory available to the operating system. Added support for loading the Embedded UEFI Shell Auto-Startup script from the network in addition to physical/virtual media. The URL describing the network (HTTP or FTP) location of the startup script can be configured in the System Utilities /Platform Configuration (RBSU), under the Embedded Shell menu. This allows for using the Embedded UEFI Shell as a scriptable deployment environment without the need for physical or virtual media (on a bare metal system). Added support to Standard Format Output (SFO) to the SysConfig command in the Embedded UEFI Shell. This allows for easier parsing of the command output using Shell scripts. Added support for boot from URL (HTTP or FTP) functionality in UEFI Boot Mode. The network settings (DHCP or static IP) and boot file URL can be configured in the new System Utilities BIOS/Platform Configuration (RBSU) Pre-Boot Network settings menu. The file can either be a UEFI Network Boot Program (NBP), or an ISO image containing a UEFI bootable OS image. The Boot from ISO support is currently limited to operating systems that have a self contained OS image (such as WinPE, mini Linux, or VMware ESX installer). Booting Windows or Linux OS installation media is currently not supported. Added support for a webclient command in the Embedded UEFI Shell. The command can be used to download files from HTTP and FTP servers. It can also be used to download ISO CD/DVD images and mount them in memory as RAM disks. Added support for an FTP command in the Embedded UEFI Shell. The command can be used to download and upload files to/from FTP servers. Added support for a Compress command in the Embedded UEFI Shell. The command can be used to compress and decompress ZIP files. Added support for a SecBoot command in the Embedded UEFI Shell. The command can be used to display the Secure Boot keys and certificates. Enhanced the RamDisk command in the Embedded UEFI Shell to support FAT32 RAM disks, increasing the disk size limit from 512 MB to 2GB. Added support for the HP Dual 8GB MicroSD EM USB Kit. This device can be plugged into the internal USB port on the server to allow a mirrored MicroSD card solution. Added support to configure the BIOS Serial Console Baud Rate to 38400 from the System Utilities BIOS/Platform Configuration (RBSU). Added a new System Utilities BIOS/Platform Configuration (RBSU) Internal SD Card Slot menu located in USB Options that allows the user to disable boot from the embedded SD card. Added support for Intel Trusted eXecution Technology (TXT). Updated OpenSSL support to version 0.9.8zb to address potential issues that might impact the UEFI Secure Boot support. Updated the HP RESTful API HP BIOS Attribute Registry resources to match the latest BIOS/Platform Configuration options. Updated the HP RESTful API HpBiosAttributeRegistrySchema to version 1.2.0, adding support for BIOS Attributes of type "Password". Also added a new GrayOut property that can be used to describe some dependency scenarios. Also updated enumDescriptions of all enum definitions in the schema. Updated the HP RESTful API HpBios, HpServerBootSettings, HpBiosMappsings schemas to version 1.1.0. Added support for self-links in these resources. Updated the language translations (non-English modes) for System Utilities. Updated help documentation for System Utilities and the Embedded UEFI Shell. Increased timeout values in Embedded UEFI Shell IfConfig command to reduce the chances of network DHCP configuration failing due to timeouts caused by delays on the network or slow response when trying to contact the DHCP server. Enhanced the UEFI Exception handler to provide extended debug and trace information when in a pre-OS environment. - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the FwUpdate Embedded Shell Application and the Firmware Update pre-boot application could hang during a firmware update and not successfully flash the device. Addressed an issue where the system might become unresponsive during boot when an unsupported memory configuration is installed on processor 2. With this unsupported configuration, in this situation there is no user feedback on the monitor or in the Integrated Management Log (IML). With this revision of the System ROM, the system will properly display a message indicating the error and halt the boot process. Addressed an issue with some network devices name display in the System Utilities. Addressed an issue that would result in incorrect or corrupt UEFI boot order data, or malformed JSON output from the HP RESTFul API HpServerBootSettings resource. This also addresses an issue in configuring the server UEFI Boot Order using HP OneView and the HP RESTful API. Addressed an issue in accessing the file systems or booting to some RAID0 logical volumes off HP Smart Array controllers. This includes accessing the file system on such drivers in the System Utilities menus and the Embedded UEFI Shell. Addressed an issue that might result in the BIOS Console Redirection support using the Virtual Serial Port to become non-functional. Addressed an issue with incorrect system time in Microsoft Windows operating systems when booted in Legacy BIOS Boot Mode. When the system time or time zone are changed, on reboot the system time might 'jump' by the current operating system time zone offset. This issue does not occur when booting in UEFI Boot Mode. The change also removes the System Utilities BIOS/Platform Configuration (RBSU) option for ACPI RTC Support. Addressed an issue where the system might experience a Machine Check Exception under heavy stress conditions when configured with an Intel Xeon E5-2609 processor. This issue does not affect any other processor models. Addressed an issue where the server might become unresponsive after a user has repeatedly entered and incorrect Power-On or Administrator Password. Addressed an issue where the server might become unresponsive after looping through the UEFI Boot Order an extended amount of time when no valid boot targets are detected. This issue only effects the server when configured in UEFI Boot Mode. Addressed an issue where a server might not be able to properly boot Windows Server 2008 R2 when configured with an Optional Graphics Card or GPGPU. Addressed an issue where the industry standard SMBIOS tables would not properly indicate the number of active cores when Intel Hyperthreading is disabled. The number of active cores would not be reported properly by some utilities. Addressed an issue where Wake On LAN does not function if the system was shutdown prior to booting an operating system (such as during the boot process or from the Embedded UEFI Shell). Wake On LAN does function properly if the system had been shut down from an operating system. Addressed an issue where the server would boot slowly when BIOS Serial Console was enabled to the iLO Virtual Serial Port. Addressed an issue where the server could be configured for Online Spare Memory Mode when the DIMM configuration did not support this mode. Addressed an issue where a USB key was still bootable when the USB Boot Functionality was disabled from System Utilities BIOS/Platform Configuration (RBSU). This issue does not impact systems configured for UEFI Boot Mode. Address an issue where the SysConfig command from the Embedded UEFI Shell could not be used to configure Secure Boot even when the user had indicated physical presence when entering the Embedded UEFI Shell. Addressed various issues where network boot support options might not be applied properly from HP Virtual Connect or HP OneView. Addressed an issue where the Legacy Boot Order menu in the System Utilities BIOS/Platform Configuration (RBSU) might have incorrect port numbers when the server is configured in Legacy Boot Mode. This issue did not affect servers configured for UEFI Boot Mode. Addressed an issue where a server configured with a Trusted Platform Module (TPM) and Microsoft Windows 2012 R2 BitLocker might incorrectly prompt the user for a recovery password following a warm reset. Addressed an issue where messages displayed during the early boot process would not be displayed properly when viewed over BIOS Serial Console. Addressed an issue where the One Time Boot Menu includes network boot options for devices even when network boot is disabled for those devices. Addressed an issue where BIOS Serial Console redirection would not work properly when the terminal was configured in VT100+ mode and the server was configured for Legacy Boot Mode. This issue does not impact systems configured for UEFI Boot Mode. Addressed an issue where Linux dmesg might report a USB error message such as "EHCI: BIOS handoff failed" when the system was configured in Legacy Boot Mode. When this issue occurs, USB support still functions properly under the operating system and the error message is erroneous. This change only prevents the display of the erroneous message and does not impact USB functionality. Addressed several issues with the legacy USB support (USB support before the operating system loads) when the system is configured for Legacy Boot Mode. This includes addressing an issue where the system might log a 303/304 Keyboard controller failure error when certain USB KVMs are attached to the system. Addressed an issue where the SATA port numbers reported in the System Utilities BIOS/Platform Configuration (RBSU) would not properly match the port numbers reflected by labels on the system. **Known Issues:** None - *Important Notes:** None **Firmware Dependencies:** None **Problems Fixed:** Addressed an issue where the server may experience a high rate of corrected memory errors that result in significant performance degradation. While this issue is rare, once it occurs, the server will continue to experience a high rate of corrected errors until the server is rebooted. This issue is NOT unique to HP servers. HP recommends that users experiencing a performance issue or experiencing corrected memory error threshold events update to this revision of the System ROM before replacing any hardware components. Addressed an issue where a system running a hypervisor-based operating system may become unresponsive when a guest operating system executes certain debug commands. Addressed an issue where a system configured for UEFI Boot Mode with multiple GPUs may not be able to properly start the GPUs under the operating system. This could result in one or more of the GPUs experiencing a "Yellow Bang" under a Microsoft operating system. This issue does not impact systems configured in Legacy Boot Mode. Addressed an extremely rare issue where the system may experience a "266-Non- Volatile Memory Corruption Detected" message and Integrated Management Log (IML) event after being powered down from a momentary power button press. This issue would only occur in a pre-operating system environment such as in the UEFI Shell. **Known Issues:** None - *Important Notes:** Ver. 1.32_03-05-2015 (B) addresses a flashing issue that only impacted servers which shipped from HP with a Windows operating system installed.
