Re-Flashing Courrupted BIOS ROM on a Gigabyte GA-6BXC motherboard

[Babulmiah]

Hi,

I have a gigiabyte GA-6BXC motherboard which will not POST. When turned on, its states the the BIOS ROM is corrupted and its checksum failed. I cannot enter the BIOS, and the PC does nothing but tries to boot from floppy disk.

I remember reading a few years back that if the BIOS of a (Gigabyte) motherboard is corrupted, then a blank floppy containing only a BIOS image should be inserted before the PC is
turned on, and once on it will image itself?

I have removed all the cards/hardisks from the PC so its just the motherbaord, CPU, RAM, graphics card and floppy disk, and am about tho try this plus the recovery procedure outlined by gigabtye below (i.i. form from a DOS/Win9x boot disk with the BIOS image and flash tool on it).

Basically what I'd like to know is if anyone know of any other recovery method incase tha above mentioned does not work e.g. can I flash another (compatible) EEPROM chip and insert it in the BISO mounting or does Gigabyte supply replacement BIOS chips?

Thanks.

I have a hard time believeing the BIOS is bad if you are getting a display that says CMOS checksum error......

Did you try clearing the CMOS memory? (by Unpluging system AC power cord and setting CMOS jumper to clear position for a minute, then place back in normal position and plugin/boot)

Did you check you battery on the mb?

Was this a result of a BIOS upgrade?

I completely forgot about clearing the CMOS! Thanks. I'll try this first!

...and no this was not caused by a BIOS flash gone wrong, or a CMOS battery swap etc. Believe it or not, we were moving the PC from one house to another and it worked fine when we left but not when we arrived at the new house!

again, thanks!

If clearing the CMOS memory does not work.... I would seriously consider trying a new battery in the motherboard. (you can get one at rat-shack). Don't forget to clear the CMOS memory after replacing the battery.
The order of events points to the battery being low/dead... (ran on standby voltage until it was unplugged during move,then the CMOS lost its memory.)
Good luck:t
