===========================================================================================
                             IMPORTANT INSTALLATION NOTES
===========================================================================================
WARNING:  
1. It is very important to follow the flash option provided in the batch file to update BIOS
   under UEFI SHELL/WINDOWS/Linux environment. 
   Using incorrect flash option to flash BIOS may cause damage to your system.

   A. Burn S2B_XXXX.BIN via fixture, or
   B. Follow below steps to update BIOS:
      EFI Shell:
      (1) Copy BIOS package to a USB flash drive.
      (2) Attaching the USB flash drive on system.
      (3) Boot up the system to EFI SHELL.
      (4) Change directory to BIOS package.
      (5) Exectute BIOS_efi64.nsh for BIOS region update or execute ME_efi64.nsh for ME region update. 
      (6) Reset system while the procedure is success. 
      
      Windows:
      (1) Copy BIOS package to a USB flash drive.
      (2) Attaching the USB flash drive on system.
      (3) Boot up the system to windows operating system.
      (4) Change directory to BIOS package.
      (5) Exectute BIOS_win64.cmd for BIOS region update or execute ME_win64.cmd for ME region update. 
      (6) Reset system while the procedure is success.  
      
      Linux:
      (1) Copy BIOS package to a USB flash drive.
      (2) Attaching the USB flash drive on system.
      (3) Boot up the system to linux operating system.
      (4) Change directory to BIOS package.
      (5) Exectute BIOS_lnx64.sh for BIOS region update or execute ME_lnx64.sh for ME region update. 
      (6) Reset system while the procedure is success. 

2. Flash BIOS by different version of flash tool in BIOS package may cause compatible issue.
3. BIOS flash part must has QE support.
4. Short MFG MODE jumper for description region re-programming is necessary.

Note:
- S2B_XXXX.BIN, S2B_XXXX.ROM, "XXXX" is version name as 1A01, 1A02, 2A01, 3A01.....
- Please enter BIOS setup and press <F9> to load default and then save settings before any test run.
- BIOS logo was put in ROM hole(cause by "Secure Flash feature" enabled), so AFU flash tool need to update
  the ROM hole with parameter "L".
- In RHEL7.0 must use chmod 755 to change privilege of afulnx_64, BIOS_lnx64.sh, ME_lnx64.sh, otherwise
  flash BIOS can not start.
- BIOS has support PLDM function to keep the setting after flashing BIOS, please confirm updated parameters include "/N /CLRCFG",
  if need to back to the default setting.
  ex. In x64 Linux environment, after BIOS_lnx64.sh execution for BIOS udpated, "./afulnx64\Afulnx_64 3Axx.BIN /N /CLRCFG" to load default.
      In UEFI Shell environment, after BIOS_efi64.nsh execution for BIOS udpated, "afuefi64\AfuEfix64.efi 3Axx.BIN /N /CLRCFG" to load default.
      In x64 Windows environment, after BIOS_win64.cmd execution for BIOS udpated, "afuwin64\afuwinx64.exe 3Axx.BIN /N /CLRCFG" to load default.

===========================================================================================
                             KNOWN ISSUES/WORKAROUNDS
===========================================================================================
- The 64G TSV RDIMM and non-Intel POR DIMM are not supported after the RC3.7.0 update. 
  System may not boot up potentially when adopting non-Intel POR compatible DIMM after upgrading to this version.
  In case the user, update this BIOS and can't boot up, please backwardly recover to your original BIOS version by using the out-band method (offline mode).
