Now I'm more confused!
Why would you disable the AGP when the video card being used is AGP-based? Even so, why should my old RIVA TNT2 card work but not the FX5200?
Ultimately, once I learn more about Debian I will be able to install the 3D drivers and all of this will be over with. But not yet! And until that time comes, I need to get the FX5200 accepted by Debian's default module.
My 'little voice' keeps telling me it will be a simple thing to fix and most times he is right. But this time, I don't know so all bets are off...
