                           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.

!!!!! If updating from any BIOS revision prior to R0018, then you must use !!!!!
!!!!! method B below to program the entire 8MB BIOS ROM image              !!!!!

Updating from BIOS revisions R0018 or later:

User can update BIOS flash image via either of the follow methods...
A. UEFI iFlash32 2.6 Build 10
   1.  Boot the system to EFI Shell
   2.  Copy IFlash32.efi and BIOS .CAP file to a HD or USB Flash Drive
       ( Do not use the Rec.CAP file as it will clear NVRAM and should
         only be used for Recovery - See Recovery Instructions below )
   3.  Map the respective storage device in system with the command
	   Shell> map -r
   4.  Change the Shell to mapped device file system
	   Example: Shell> fs0: (or fs1:)
   5.  Run the IFlash32 utility on the prompt
	   fs0:\> IFlash32 [File Name] /u /ni
   6.  Reboot system after the update is completed.

B. Use flash programmer to burn the new BIOS ROM image (8MB) into the flash chip.

C. Instruction for R0066 and later version update

   1.  Boot the system to EFI Shell
   2.  Copy IFlash32.efi and BIOS .CAP file to a HD or USB Flash Drive
       ( Do not use the Rec.CAP file as it will clear NVRAM and should
         only be used for Recovery - See Recovery Instructions below )
   3.  Map the respective storage device in system with the command
	   Shell> map -r
   4.  Change the Shell to mapped device file system
	   Example: Shell> fs0: (or fs1:)
   5.  iflash32 /u /ni T066.cap
   6.  Reboot system after the update is completed.
   7.  Do *NOT* interrupt the BIOS POST during the first boot.
   8.  Boot to UEFI Shell again,  then change the Shell to mapped device file system
   9.  iflash32 /u /ni /nv R0066.cap
   10. Reboot system after the update is completed.

   Notes for R0066 update:
   1) R0066 BIOS contains security fix. After updating R0066, BIOS is not allowed to downgrade to previous revision 
   2) T066 is a transition capsule. Earlier version than R0066 cannot directly skip updating T066 if user need update
      R0066. User must firstly update to T066, and then update to greater version than T066 like R0066 or later version.


================================================================================
                        BIOS RECOVERY INSTRUCTIONS
================================================================================

The Recovery process can be initiated by setting the recovery jumper
(called BIOS Recovery Boot Jumper)

A BIOS recovery can be accomplished from SATA CD and USB Mass Storage device. 
Please note that recovery from USB floppy is not supported on this platform. 

The SATA CD image for recovery is created using El-Torito format image (bootable).

The recovery media must contain the following files under the root directory:
   1.  FVMAIN.FV
   2.  UEFI iFlash32 2.6 Build 10
   3.  *Rec.CAP
   4.  Startup.nsh (update accordingly to use proper *Rec.CAP file)

BIOS starts the recovery process by first loading and booting to the recovery image 
file (FVMAIN.FV) on the root directory of the recovery media (SATA CD or USB disk).
This process takes place before any video or console is available. Once the system boots 
to this recovery image file (FVMAIN.FV), it will boot automatically into EFI Shell to 
invoke the Startup.nsh script and start the flash update application (IFlash32.efi). 
IFlash32.efi requires the supporting BIOS Capsule image file (*Rec.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 switch the recovery jumper back to normal operation and restart
the system by performing a power cycle.


The following steps demonstrate this recovery process:
   1.  Power OFF the system.
   2.  Insert recovery media.
   3.  Switch the recovery jumper. Details regarding the jumper ID and location
       can be obtained from the Board EPS for that Platform.
   4.  Power ON the system.
   5.  The BIOS POST screen will appear displaying the progress, and system automatically 
       boots to the EFI SHELL.
   6.  Startup.nsh file executes, and initiates the flash update (IFlash32.efi)
       with new capsule file (*Rec.CAP). The regular IFlash message will be displayed at
       the end of the process, once the flash update succeeds.
   7.  Power OFF the system, and revert the recovery jumper position to "normal operation".
   8.  Power ON the system.
   9.  Do *NOT* interrupt the BIOS POST during the first boot.

================================================================================
                            KNOWN ISSUES/WORKAROUNDS
================================================================================

- The UEFI iFlash32 BIOS Update Utility should only be used after the R0018 or
  later BIOS version is properly installed on your system.  Refer to the section
  regarding INSTALLATION NOTES above.

- If performing BIOS recovery process and the system hangs at POST Code 0x34 before
  the BIOS POST screen appears, it may a require a warm reset via the front panel
  or AC power cycle for recovery to properly detect the recovery media and load
  FVMAIN.FV from the recovery device.

- For S5500BC, S5520HC, S5520SC, S5520UR, & S5520WB Platforms, please ensure that
  the BMC FW installed is v0.31 or later before updating to the R0029 or later
  BIOS release.  Using BIOS R0029 with any BMC FW prior to v0.31 could cause the
  system to automatically shutdown upon A/C power cycles.
  
- Outstanding STT 5.19.14 failures are tracked through PVCS tracker #35116

- BIOS R0037 requires a firm key press during POST to get a key accepted. No pecking.

- BIOS after R0047 Does not support Intel® Xeon® Processor 56xx  A0 processor boot.

- BIOS R54 has implemented the Recovery process enhancement solution to fix the recovery 
  dependency of the BIOS variables. When customer enables both recovery Jumper and Clear 
  CMOS jumper, BIOS variables in VPD area will be cleared and CMOS values will be set to
  default.

- OFU cannot be used to update R0066. 

- After updating R0066, AMIBCP cannot work.
