I have this motherboard and wondering if anyone know where to get the BIOS
upgrade information. All they say in the manual is MADE IN USA, and no phone number
and no address. 

I'm using DOS, Windows 95, and Linux on my machine. I tried the OS/2 Warp and cannot
get the Mitusmi 4X IDE and NCR drivers installed. I suspect the it's the problem
with the motherboard. With those drivers installed, OS/2 install simply stops..
