What if things go wrong

if you use the wrong Flash BIOS or if the writing process gets int errupted,
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 scr een because the boot-
block BIOS only supports an ISA videocard.

If you do not want to change your AGP video setting than proceed as
foll ows:

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 with the corrupt
one. This should work fine with most boards because the BIOS is shadowed
in RAM.

4. Flash an appropriate BIOS to the corrupt chip and reboot.

NOTE

: Use a flasher from MRBIOS (

http:// www.mrbios.c om

). Utilities that

come with your motherboard oft en use specific BIOS-hooks. Because you
have booted with a BIOS not written for your motherboard they usually don't
work. The MR Flash utilities communicate directly with your Flash Rom and
always work. In most cases they flash a non-MRBIOS to your BIOS chip
without problems.
