Some of my colleagues request 169.21 modded inf for 3DM2001. Today added suport for 9800gt also.
Tested by me on 9800gt/9800gtx/9800gtx+ and gts250. Just go via update driver, don't search, i will choose ..., have disk and select proper inf, as shown in the screens.
Good luck on the best bench ever.
