Actually I've tried 3 different PCI cards in both slots and they all work fine. I have 2 different single channel BT878 based PCI cards in there now capturing CCTV 24 x 7, the machine stays up for months. That's why it's so odd. Any other pointers? Does the kernel need the BIOS to detect the card right?
