nVidia 128ZX Win2K and Half-Life

I had openGL working on windows 98se, upgraded to Win2k and openGL no longer works at all! I’ve tried re-installing drivers, half-life and directX to no avail. Any ideas? It’s a Creative Labs Graphics Blaster 128 (OEM) Model CT6730 and no one supports the damn thing. nVidia 128ZX chipset, AGP.

Win2K doesn’t support the Riva128zx with OpenGl.
This hurts but you need to upgrade.
