Turns out my assumption was incorrect. I tried installing my video card in a friend's computer and it freaked out there as well. He had an AGP4x card lying around, so I borrowed that and now all is going well.

So nevermind.

Oh, and the suggestion to install drivers during Win2k install was accurate. Worked great. Even allowed me to use the RAID stuff. Now to see if I can see the RAID under Linux....
