ok,
1. your PII system is too old to support expandable graphics ports.
2. video graphic card, 3D Accelerator card, and video card are all the same thing.
3.for the add enw hardware deal, you just installed the windws drivers for the gamecard, not the actual, physical hardware.
4. if you plan on playing any games, you need to get rid of that pentium II notebook and get at least a Pentium 4 notebook with expandable graphics adapters. check out the Dell XPS Gen-2.
