It has an edge connector, a full 64-bit ribbon connector, and a 32-bit ribon connector. As far as I can tell, there are no shared signals. It is made by Adex electronics, and is part number: P/NPCITX3S1 884-335-185 I tried two different systems, and the problem is identical, so I believe it is not a hardware manufacturing glitch. It may be a hardware design issue in either the riser or the motherboard. Or a BIOS PCI irq mapping problem... Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
