Mind if I jump in here??
I have the SOYO Dragon board with RAID and onboard sound. And the Gainward GFORCE2 videocard with 3D rendering, 64 meg RAM on the card. I forget the stock number. If that's the card you have, I may have some helpful suggestions.
My onboard sound wouldn't work, had to install a Soundblaster. Everything else works fine, very tweakable BIOS.

The Gainward: forget the manual for install instructions. Manual tells you to install the "Gainward" drivers; what you need are the drivers labeled NVIDIA MX/MX400; I went around & around for 4 hours trying to get the "Gainward" dirvers to load, until I got mad and went for the above mentioned drivers and let the chips fall where they may. Drivers loaded and the card works beautifully, and the monitor adjustment tools are great. First I had to shut down the computer to "off", then re-start because it gets a "path" after repeated load attempts and wouldn't load the drivers, and then the MX400 loaded beautifully.
