BIOS Recovery
AMI BIOS

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.

BIOS recovery
Award BIOS
The AWARD BIOS has a similar procedure to AMI. To recover an AWARD BIOS you will need to create a bootable floppy diskette and add the desired BIOS file (we recommend using the most recent). Award BIOS's generally are in .BIN format, where as AMI was .ROM format. You will also add an AWARD flash utility (usually awdflash.exe) and an AUTOEXEC.BAT file.

The AWARD BIOS does not automatically restore the BIOS information to the 'system block' like the AMI BIOS does. You will need to add the commands necessary to flash the BIOS in the AUTOEXEC.BAT file. The system will run the AUTOEXEC.BAT file, which contains the flash instructions.

Note: 12345678.BIN represents the name of your BIOS.

Step by Step:

1. Create a bootable floppy diskette

2. Copy the BIOS file and flash utility to the diskette

3. Create an text file with any standard text editor and add the following lines

@ECHO OFF

awdflash 12345678.BIN /py/sn/f/cc/r

Exchange the awdflash with the name of whatever flash utility you are using, and replace the 12345678.BIN with the name of the BIOS file you are using. The parameters are explained here:

py = program yes
sn = save no
f = flash
cc = clear cmos
r = reboot
