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?

you should have a "multimedia device" listed in your device manager,probably somewhere between sound and controller devices.if the card is not detected at all,chances are it is dead..

Maybe your Voodoo2 is dead, try it on another System  to except an MB-Failure
but i think your Voodoo2 isn't working after a long time lying somewehre...
