How to recovery AMI BIOS if update fail?
Boot Block Recovery from Floppy Disk
Boot Block Recovery from Floppy Disk is a standard feature of the AMIBIOS8 core, and
is enabled by default. This allows the user to recover a BIOS image using a standard
floppy disk without the need for additional utilities.
Instructions for manually initiating Boot Block Recovery from Floppy Disk:
1. Insert the floppy disk with the new BIOS file in the root directory into
drive A:. In most cases the file must be named AMIBOOT.ROM for the
recovery process to load the file. However, this filename may differ
from one product to another. Please consult the system motherboard
documentation for more information.
2. Press and hold the <Ctrl> and <Home> keys down while turning the
power on. Continue to hold the <Ctrl> and <Home> keys down until the
access light on the floppy drive comes on. It may take a few seconds or
more before this light turns on.
3. Release the <Ctrl> and <Home> keys. AMIBIOS issues a series of beep
codes that indicate that the system BIOS ROM file is being updated.
There will also be a progress dialog displayed on the screen after the
file has been loaded.
4. When the flash ROM has successfully been programmed, the computer
will reboot. Please do not interrupt the BIOS flash process until it has
One function of the AMIBIOS Boot Block code it to test the integrity of the BIOS image
in flash memory. If AMIBIOS8 Boot Block code detects a problem with the BIOS image,
Boot Block recovery will automatically be initiated. This condition will be indicated
using a series of beep codes.
Boot Block Recovery from IDE CD-ROM
Boot Block Recovery from IDE CD-ROM is nearly identical to Boot Block Recovery from
Floppy Disk, except that the BIOS image is loaded from CD-ROM. The BIOS image may
be loaded from CD-R & CD-RW drives, even if the drive was burned as a multi-session
disk. In most cases the file must be named AMIBOOT.ROM for the recovery process to
load the file.
Boot Block Recovery from USB Storage
Boot Block Recovery from USB Storage is nearly identical to Boot Block Recovery from
Floppy Disk, except that the BIOS image is loaded from a USB Storage Device. This
includes a variety of USB devices that meet the USB Mass Storage Class definition.
• USB Floppy
• USB Flash Drive
• USB CDROM & CDRW
