I just installed NT4.0 with SMP and I noticed that if I set my BIOS to MPS 1.4 that the adaptec 2940u2w driver would ALWAYS fail during bootup. When I switched back to MPS 1.1 everything was stable again. Maybe going back on your BIOS MPS version will make things stable with your adaptec card? Reece Hart wrote: > Cheers.
