Был раз похожий случай. Я просто файл BIOSа залил на CD-болванку, безо всяких заморочек с образами.

Никто не мешает использовать образ дискеты с поддержкой CD и все, что относится к прошивке, поместить в основную часть CD:).

Я поиздеваюсь:).
Описание, мягко говоря, несет мало смысла - нет детального описания, куда и какие файлы были помещены, на чем именно останавливается загрузка (и происходит ли она вообще).
Автору виднее, конечно же:).

BIOS RECOVERY INSTRUCTIONS
=============================================================================
Recovery process can be initiated by setting the recovery jumper (called force recovery)
or invoked because of flash damaged.

A BIOS recovery can be accomplished from ATAPI-CD. ATAPI-CD image for recovery is created
using El-Torito format image (which is bootable).

The recovery media must contain the following image file: FV_MAIN.FV under root directory.
The system should also contain a DOS bootable disk (HD, USB drives or CD, etc.)
which must include the following image files:
1. IFLASH32.EXE
2. *.CAP
3. AUTOEXEC.BAT

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 inserted ATAPI-CD.
This process takes place before any video or console is available.
Once the system boots to this recovery image file (FV_MAIN.FV), user should select
booting the DOS disk which contains the above file list. The further process would
load and execute the AUTOEXEC.BAT and the flash update application (IFLASH32.EXE).
IFLASH32.EXE requires the supporting BIOS Capsule image file (*.CAP).
Once the recovery process is complete, it waits for a user to switch the recovery
jumper back to normal operation and restart the system by doing power cycle.

The following steps illustrate the recovery process:
1. Insert recovery media (ATAPI CD) with the FV_MAIN.FV on the root directory.
2. Insert the disk with all the required files (IFLASH32.EXE, AUTOEXEC.BAT, *.CAP).
User could also put all the files in both step 1 and 2 together into one disk
3. Change the recovery mode jumper (BIOS RECV from normal operation to recovery operation.
The details of the jumper can be found in the Board EPS.
4. Power on the board.
5. The BIOS POST screen will appear and display the progress. BIOS continues to
boot to DOS from the media.
6. AUTOEXEC.BAT file is invoked and it will initiate the flash update (IFLASH32.EXE)
with new capsule file (*.CAP). The message will be displayed if flash update succeeds.
If flash update fails, it will be notified to the user.
7. Once the flash update is completed, revert the recovery jumper back to normal operation.
8. Perform the power cycle.
