Video Drivers.. HELP!!

[Un-nerV]

First question.. I have an IBM Aptiva and need to upgrade my open GL drivers... when I check device manager, it says that my video adapter is Rage Pro 3D... my system specs simply say SIS 530 as far as the video card is concerned. Which ATI drivers should I be using for open GL?

THE OLDER APTIVA'S HAD THE SIS VIDEO CARDS ABOUT HALF WAY THROUGH 1997 SO IF YOUR SYSTEM IS IN THIS RANGE GO THE SIS CARD THE YEAR 1998 FOR APTIVA WENT TO ATI CARDS,
IF YOU HAVE TO CHOOSE BETWEEN RAGE AND SIS GO THE SIS AS THIS WILL MOST LIKEY BE THE CHIP SET.

I did some more looking around and the chip set is ATI Rage Pro.. I opened my machine up to be sure. I've downloaded the drivers for this chipset from the ATI homepage.. but what I really need is to be sure I have the right open GL drivers. I'm trying to run Q3Radiant, and it's simply not working. Folks there are telling me it's my drivers, however, I've not found out from anyone which drivers I need. Thanks for your help!
