That's a Via KT-133 chipset board right? Have you installed the new VIA 4 in 1 drivers. It seems they are up to version 4.26. I only have Intel machines, but from what I understand, the 4 in 1 drivers are essential for proper functioning of Geforce2 cards with that chipset. Stroll on over to http://www.viahardware.com/ and have a look. BTW, I don't know what a pirq is. You don't really mention what kind of problems you're having ... maybe they are not related to IRQ conflicts ... I haven't had any conflicts with my NVIDIA AGP boards before. (Including my Creative Annihilator 2) ... but then again .... I'm running a different motherboard, chipset and probably other cards as well.
