                             IMPORTANT INSTALLATION NOTES
===========================================================================================
WARNING:
   It is very important to follow the flash option provided in the batch file 
   BIOS_dos.bat/ME_dos.bat for DOS, 
   BIOS_win64.cmd/ME_win64.cmd for Windows, 
   BIOS_lnx64.sh/ME_lnx64.sh for Linux. 
   Using incorrect flash option to flash BIOS may cause damage to your system.

   There are two way to flash BIOS image.
   1. Burn S2S_xxxx.BIN via fixture or,

   2. Update BIOS region by AFU tool:
   For DOS environment, follow below steps to update both BIOS and ME FW:
   (1) Unzip the release package to the same folder in a HDD or USB Flash Drive with bootable DOS.
   (2) Insert the USB Flash Drive or HDD mentioned in step (1).
   (3) Power on the system and boot into this USB Flash Drive or HDD.
   (4) Execute batch file BIOS_dos.bat to update BIOS.
   (5) Execute batch file ME_dos.bat to update ME FW.
   (6) After the update finished, perform an DC cycle, the new BIOS/ME FW runs.
   (7) Then, please enter setup, press <F9> to load default and save before any test run.
 
   For x64 Windows environment, follow below steps to update both BIOS and ME FW:
   (1) Power on the system and boot into Windows OS.
   (2) Unzip the release package to the same folder in the HDD.
   (3) Open Command Prompt, change to the folder with release package located.
   (4) Execute batch file BIOS_win64.cmd to update BIOS.
   (5) Execute batch file ME_win64.cmd to update ME FW.
   (6) After the update finished, perform an DC cycle, the new BIOS/ME FW runs.
   (7) Then, please enter setup, press <F9> to load default and save before any test run.
   
   For x64 Linux environment, follow below steps to update both BIOS and ME FW:
   (1) Power on the system and boot into Linux OS.
   (2) Unzip the release package to the same folder in the HDD.
   (3) Open Terminal, change to the folder with release package located.
   (4) Execute batch file BIOS_lnx64.sh to update BIOS.
   (5) Execute batch file ME_lnx64.sh to update ME FW.
   (6) After the update finished, perform an DC cycle, the new BIOS/ME FW runs.
   (7) Then, please enter setup, press <F9> to load default and save before any test run.
   
Note:
- Current AFU tool version: v5.08.01.Q.0401
- BIOS_dos.bat/BIOS_win64.cmd/BIOS_lnx64.sh updates BIOS regions only.
- ME_dos.bat/ME_win64.cmd/ME_lnx64.sh updates ME firmware regions only.
- S2S_xxxx.BIN, S2S_xxxx.ROM, "xxxx" is version name as 3B06.....
- BIOS update script will use '/N' by default, please note that this parameter will clear all BIOS Setup setting,
  this is for avoid NV structure be changed after RC/Module updated.
  If you can make sure the RC version is the same, you can remove 'N' parameter by yourself.
- 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.  
  
===========================================================================================
                             KNOWN ISSUES/WORKAROUNDS
===========================================================================================
- Please update CPLD first to support Broadwell two CPU configuration, or it may not boot up.
- From previous BIOS 2BXX update to version after 3B02, it would need to add /X to avoid ROMID issue.
