Zoolan,
I think I can help you out...just had that same problem with my new XP install (finally folded last night and did the upgrade from 98se

).
This is assuming you have no ati driver installed for your card, and I take it you went far enough into the install that the files were unzipped to the "c:ATI/something-or-other" directory, right?
1. go into 'device manager' and right click on the unrecognized VGA adapter and select 'properties'
2. click on 'reinstall driver' (or it may say 'change driver') button.
3. tell it you want to pick the driver to install (don't let it search for the best one...it won't come up with sh1t)
4. select display driver for driver type and select 'have disk'
5. Browse to the "c:ATI/something-or-other" folder that has the unpacked driver files.
6. go into the folder for windows 2k, at this point you should see a file with a .inf extension. select it and click open.
7. click next to install the driver and that should do it!
