Howto : Flash the BIOS
What if things go wrong
if you use the wrong Flash BIOS or if the writing process gets interrupt-
To flash your BIOS you'll need
1) a xxxxx.bin file that is a file image of the new BIOS
2) AWDFLASH.EXE a utility that can write the data-file into the BIOS
chip.
Create a new, clean DOS 6 bootable floppy with "format a: /s".
Copy flash utility and the BIOS image file to this disk.
Turn your computer off. Insert the floppy you just created and boot the
computer. As it boots up, hit the [DEL] key to enter the CMOS setup. Go
to "LOAD SETUP (or BIOS) DEFAULTS," and then save and exit the setup
program. Continue to boot with the floppy disk.
Type "AWDFLASH" to execute the flash utility. When prompted, enter
the name of the new BIOS image and begin the flash procedure. Note: If
you reboot now, you may not be able to boot again.
After the flash utility is complete, reboot the system.
What to do when the Award flasher says:
Insufficient memory
1. In CMOS Chipset Features Setup, Disable Video Bios Cacheable.
2. Hit Esc, F10, Save and exit.
3. Flash the BIOS and reboot
4. Enter CMOS Chipset Features Setup,and Enable Video Bios
Cacheable,hit Esc, F10, Save and reboot.
ed, there is a fat chance that your computer won't boot anymore.
How can you recover a corrupt BIOS ?
Boot-block booting
(this works only for Award BIOS)
Modern motherboards based on Award BIOS have a boot-block BIOS.
This is small area of the BIOS that doesn't get overwritten when you
flash a BIOS. The boot-block BIOS only has support for the floppy drive.
If you have the AGP video enabled you won't see anything on the screen
because the boot-block BIOS only supports an ISA videocard.
If you do not want to change your AGP video setting than proceed as
follows:
The boot-block BIOS will execute an AUTOEXEC.BAT file on a bootable
diskette. Copy an Award flasher & the correct BIOS *.bin file on the
floppy and execute it automatically by putting awdflash *.bin in the
AUTOEXEC.BAT file.
Solution 2:
Hot-swapping
1. Replace the corrupt chip by a working one. The working BIOS doesn't
have to be written for your board, it just has to give you a chance of
booting to DOS.
BIOSs for the same chipset mostly work. (Chipsets that not differ too
much also mostly work. (e.g. Triton FX chipset and Triton HX chipset)
2. Boot the system to DOS (with floppy or HD)
3. Be sure that the System BIOS cacheable option in your BIOS is
enabled! If so replace (while the computer is powered on) the BIOS chip
