AMI BIOS Recovery
AMI has an embedded recovery technique in the ‘boot block’ of the BIOS. In the event that the BIOS becomes corrupt the boot block can be used to restore the BIOS to a working state. The routine is called when the ‘system block’ of the BIOS is empty or corrupt. The restore routine when called will access the floppy drive (1.44Mb floppy disk drive) looking for a file named AMIBOOT.ROM.
This is the reason the floppy drive light comes on and the drive appears to be in use. If the file (AMIBOOT.ROM) is found it is loaded into the ‘system block’ of the BIOS to replace the corrupted information.
To restore your BIOS copy the most recent version of your motherboards BIOS file to a floppy diskette and rename it AMIBOOT.ROM. The diskette does not need to be bootable or contain a flash utility. It will access the floppy from 2-5 minutes the system will beep four times. Remove the floppy diskette from the drive and reboot the computer. if when you turn on the system it does not try to access the floppy, press and hold the ‘CTRL’ and ‘HOME’ keys at the same time. This will force the system (assuming the ‘boot block’ isn’t corrupted) to access the flopy and look for the AMIBOOT.ROM file.
Note: 12345678.BIN represents the name of your BIOS.
Step by Step:
1. Rename the desired AMI BIOS file to AMIBOOT.ROM and save it on a blank floppy disk. e.g. Rename 12345678.ROM to AMIBOOT.ROM
2. Insert this floppy disk in the floppy drive. Turn On the system
3. If no floppy access occurs press and hold Ctrl-Home to force update. Follow insructions on the screen and it will read the AMIBOOT.ROM file and recover the BIOS from the A drive.
4. When 4 beeps are heard you may remove the floppy disk.
5. Restart the computer.
If this does not work, try this:
Method 2. Asus only…
1. Create bootable flopy using the HP Tool and MiniDOS:
When creating the boot Floppy, select from Folder Options to view the hiden and system files and delete or rename the file config.sys if present.
Couse we need DOS with no additional programs that are loaded, which could interfere with the operation of the BIOS flash application.
2. Create new text document and type the folowing:
Afudos.exe /iamiboot.rom /pbnc /n
Autoexec.bat download link:[download id="26"]
save it as autoexec.bat and copy it to the boot flopy you have created.
3. Rename your BIOS to amiboot.rom and copy it to the bootable flopy.
4. If no floppy access occurs press and hold Ctrl+Home to force update.
5. When there is no more activity, wait for a while and restart the computer.
