Need update for my old motherboard, win98 does not shut down

[duchesne]

I already searched this site and the internet, but I can't find the bin file to update my bios. Does somebody know where I can find it ?
I want to solve my win98 does not shut down properly problem and I can't log off and go to dos.

If it's Win98SE, then try applying the shutdown patch first. It's available from Microsoft's site.
