Hi,

I have a Gigabyte ALI chipset that I tried to upgrade the BIOS on - - well, it crashed. I need to get it back where it was.

I made the boot disk, but it will not boot. I have the old BIOS saved.

Help - - I need this up by tommorrow.

Try looking in your manual to see if there are any jumpers to short out the motherboard BIOS, if there is.....short it out.  That might help.  You didn't say if you can get any prompt on the screen or if how exactly you can't "boot" your floppy.

Please elaborate

---------
After flashing a motherboard, you must clear all BIOS data. Because some datas does not "match" with new bios.
To reset data  :
find a jumper to clear CMOS data
or shortcut battery one second
or unplug battery

Make a try ...
---------

A bad BIOS has no way to be reversed.

3 ways :

1)reprogramming BIOS :
Generally you can unplug flash memory ( pll plastic bracket ( or support ?))
You have source code (bin file ).
Find a friend or a student who works in a electronic laboratory. With a Flash/Eprom reader/writer ( example Data I/O or SMS system)you can flash your bios.
OR
Visit this site :
www.badflash.com -> for 20$, your chip could be reprogrammed.

2) find a new BIOS chip.
3) buy a new motherboard ...

I just pulled a BIOS chip - AWARD BIOS SI21 2 M - and will try to put it on the motherboard in a while and will let you know.

Fourth way:

On a second computer, find a spare hard-drive, and load a minimal MS DOS system onto it.
Then, copy the BIOS-flash program, and the old BIOS data onto it.

Transplant this hard-drive into your computer, and set the boot-order to 'C:' first.

Your BIOS may be able to boot from the hard-drive, and then "flash-back" to the saved BIOS.

Sometimes, a "flashed" BIOS is just "wounded", not "dead".

If it just is "wounded", then you still may be able to boot from 'C:', in order to "flash-back" the BIOS.

If it's dead, it's dead as Somebody_Else implies.

8-)   sad but true, hopefully you can find a new bios chip as this would be the easiest/cheapest replacement.  the modbo's website is the best place to start (I would think) for that.

I have the exactly the same system as you! Should I not update my BIOS then? I was thinking of updating it.....was it that you did something wrong or that it messed up?

I believe that I messed up and load the wrong BIOS - - I would try again if I had to.
