        INSTALLATION NOTES
================================================================================

WARNING:  It is very important to follow these instructions as they are written.
Failure to update using the proper procedure may cause damage to your system.

User can update BIOS flash image via the next method...
    
    UEFI iFlash32
    1.  Copy the entire contents of the zip file to the root of a USB flash drive
    2.  Boot to uEFI Shell, then change the Shell to the mapped device (USB flash drive)
        Example: Shell> fs0: (or fs1:)
    3.  Run updBIOS.nsh, updME.nsh, updFD.nsh and reset the system after each region upgrade
    4.  Reboot the system after the last upgrade is completed
    5.  Do *NOT* interrupt the BIOS POST during the first and second boot
    
================================================================================
        BIOS RECOVERY INSTRUCTIONS
================================================================================

The Recovery process can be initiated by setting the recovery jumper (called BIOS Recovery Boot Jumper)
Details regarding the jumper ID and location can be obtained from the Board TPS.

BIOS starts the recovery process by first loading and booting to the recovery image from backup BIOS region.
This process takes place before any video or console is available. Once the system boots to the recovery image use the following steps to perform the BIOS recovery:

   1.  The BIOS POST screen will appear displaying the progress and it automatically
       boots to the uEFI SHELL
   2.  Follow any of the next two methods for recovery process.
   
   Note: Recover mode will clean up all user previous changed BIOS settings including ITK saved settings 
   
BIOS update under recovery mode as below two methods:

The USB flash drive is necessary for the primary BIOS upgrade and must contain the following files 
under its root directory:
   1.  uEFI iFlash32.efi (including iflash32_temp.efi and ipmi.efi )
   2.  *.CAP( the released BIOS capsule which version you expect to update)
   3.  UpdBIOS.nsh (update accordingly to use proper *.CAP file)

  A Method: Install USB media after recovery boot to shell, you need to follow below steps
   1. Under Shell, type "map -r" to map all disc
   2. Change the Shell to mapped device file system
      Example: Shell> fs0: (or fs1:)
   3. Execute the UpdBIOS.nsh script for BIOS update, wait for BIOS update complete
   4. Power OFF the system, and revert the recovery jumper position to "normal operation".
   5. Power ON the system.
   6. Do *NOT* interrupt the BIOS POST during the first boot.
  
  B Method: Install USB media prior to recovery boot
    It will boot automatically into EFI Shell to invoke the Startup.nsh script and start the flash update application.
    IFlash32.efi requires the supporting BIOS Capsule image file (*.CAP). After the update is complete, there will be a message displayed stating that the "BIOS has been updated successfully" indicating the recovery process is finished. 
    The user should then power off the system and revert the recovery jumper back to normal operation and restart the system by performing a power cycle.

Note:
    The Startup.nsh file includes parameters to upgrade not only the BIOS, but the ME, FD, BMC and FRUSDR
        
================================================================================
        IMPORTANT NOTICE
================================================================================

1. Package C-State only works well with Xeon Scalable Family H0 parts, for other Xeon Scalable Family stepping, C6 non-retention is hardcode from BIOS side.
2. BIOS R00.01.0001 does not support online downgrade to any Dxxx or Xxxx BIOS.
3. BIOS R00.01.0001 removed Xeon Scalable Family A1 microcode(m1350651_8000002B) and Xeon Scalable Family B0 microcode(m9750652_80000035).
4. Removed 'UpdateNvram' support for iflash32 tool for security reason of SRA bios.
5. Security revision upgrade to v0002 on BIOS R00.01.0002 will prevent BIOS downgrade via normal mode to R00.01.0001, user can use BIOS recovery mode for BIOS downgrade. Although Intel doesn't recommend downgrading firmware
6. One new production key is integrated onto R0004 BIOS, which will correct an OEM string. 
7. This release include security revision upgrade to version 0004. This will prevent BIOS downgrade via normal mode to previous version with lower security revision, user can use BIOS recovery mode process for BIOS downgrade.
8. System will prevent downgrading ME from 04.00.04.288 to 04.00.04.235 or older version, if system BIOS version is R0009. This is an expected behavior.
