I was bored this weekend and decided to pull out some old school games.  Some of them had 3dfx support, so I found my Voodoo2 (it's the 3dfx-branded V2 1000).

Trouble is, my computer doesn't even recognize that it's there.  It doesn't show up in Device Manager, or even Linux when I run lspci.

I get video through the pass through cable, so that makes me think that everything is OK electrically.  I even tried moving it to a different PCI slot.

System is an Athlon 700MHz, AMD Irongate 751 chipset, 384MB of RAM, and a Matrox G400 as my main video card, running Windows 98 SE.  Are there maybe any known issues with this chipset and 3dfx cards?
