I was doing A Live Update on my bios and it crashed when it was installing. As we all know this is never good. (I have been having errors with the motherboard, otherwise I would'nt have been updating the bios in the first place), as a result I get an error on start up.

Bios Rom Checksum Error
Keyboard error, or no keyboard present.

I have used a win98 boot disk to try and flash the bios that way, with the latest update, but then I get Unkown Flash Type. What I need now is an old version to try and see if back dating the bios will work instead. except I dont know where to look, the website for my motherboard only has the latest.

The motherboard is a WinFast K7S741GXMG-6L, Empowered by Foxconn
The website is www.foxconnchannel.com

If anybody could help to find an old flahs update for me, or has any other advice, this would be much appreciated, thank you in advance.
