Missing Resolutions in Win2K?

[LocutusX]

My rig appears to be suffering from the missing resolutions problem. OS is Win2K, vid card is Asus 6800 DDR (Geforce 1) and I noticed this about 2 weeks or so ago, when I was reinstalling Unreal Tournament. A quick check of other Direct3D apps shows the same thing. No 1024x768 rez! That's my favourite rez, so it kinda sucks that it's gone. I tried the latest Loki OpenGL renderer for UT and while it's a bit faster, there is still no 1024 rez! I've been using Det 7.52 for the past 3 months, I just upgraded to 7.58 WHQL and the problem is still there. Any suggestions?
