Thanks to all! John P - I posted a new thread concerning your suggested motherboard/CPU upgrade in the "motherboards" forum:

"Are you saying youre tnt card did work but now it doesnt??"
If memory serves, the TNT did have 3D acceleration working for some games, but was never very easy to work with that way, particularly with Quake2. Sorry for the vagueness, but that has been several years ago and I have forgotten the details. The TNT does still work in 2D.
At this time, selecting "OpenGL" or any other option except "software" in Quake II video setup returns the console error, "3D acceleration not detected."
