Help - OpenGL & Win2K

I hate to add to the whining, but I need assistance understanding how to get OpenGL drivers for a Win2K system.

Like several other dolts I’m trying to find this mysterious OpenGL s/w to run RtCW.

I’ve looked on the web, but to no avail.

Can anyone assist a confused guy?

Comp: Dell Inspiron
VCard: ATI Rage (mobility??)
OS: Win2K
