ATI Rage Mobility M1 & Windows 2000

I think that Open GL is either not installed or not working properly under Win 2k.

There doesn’t appear to be any ATI Rage Mobility Open GL drivers to download anywhere. The Rage 128 ones don’t work.

Can someone help.
Quake III just gives me a grey screen, and gives me a program error.

Its definitely failing because of the video driver.

Can you tell me where I can go for an ATI Rage Mobility Open GL driver?
