Loading BIOS Defaults
Different mechanisms exist for resetting the system configuration to the default values. When a
request to reset the system configuration is detected, the BIOS loads the default system
configuration values during the next POST. The request to reset the system to the defaults can
be sent in the following ways:
•
A request to reset the system configuration can be generated using the BIOS System
Configuration Utility (Setup).
•
A reset system configuration request can be generated by moving the clear system
configuration jumper.

Multiple Boot Blocks
Two boot blocks are available on this server board.
Multiple Boot Blocks fault tolerant realization requires BIOS to: 1) recognize the second boot
block and dispatch modules within it; 2) provide flash update interface (for utility) that has fault-
tolerant flash update algorithm embedded, by which at any time point, there always exists a set
of boot blocks that could recover the system back if the flash update is failed.
4.6
Recovery Mode
The recovery process can be initiated by setting the recovery jumper (called force recovery).
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. SATA CD image for
recovery is created using El-Torito format image (which is bootable).
The recovery media must contain the image file: FV_MAIN.FV, under the root directory. And
also the following files:
1.
IFLASH32.EFI
2.
*.CAP
3.
Startup.nsh
The BIOS starts the recovery process by first loading and booting to the recovery image file
(FV_MAIN.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 (FV_MAIN.FV), it would boot automatically into EFI Shell and invoke the
Startup.nsh. and the flash update application (IFLASH32.EFI). IFLASH32.EFI requires the
supporting BIOS Capsule image file (*.CAP). At last, there would have two short beeps
indicating the completion of the recovery. User should switch the recovery jumper back to
normal operation and restart the system by doing power cycle.
