The drivers originate from a nForce driver package and the .inf file (windows information file) only supported the nForce chipset based graphics cards. The nForce drivers where fully WHQL certified, unfortunately as we had to alter the .inf file they are no longer that.
We have fixed/modified the .inf file and now the driver is compatible with all NVIDIA videocards. The drivers are dated 30/7/2002. The drivers have been tested on one of my Windows 2000 systems and work peachy. Right now 3D Mark 2001 is doing nice numbers. Unfortunately we can only bring you a Windows 2000/XP version.
Please beware of the fact that they are considered beta and non-official.
