Hi!
It is indeed strange, here are a few ideas:
- If its a Windoze card it will never show up in the Mac environment (duh!)
- There were several PCI revisions, with different bus widths and voltages! (great for backwards compatibility, huh!). It might be an incompatible revision or even a newer PCIe, which is unlikely unless you are blind:
"The first version of conventional PCI found in consumer desktop computers was a 32-bit bus using a 33 MHz bus clock and 5 V signalling, although the PCI 1.0 standard provided for a 64-bit variant as well. These have one locating notch in the card. Version 2.0 of the PCI standard introduced 3.3 V slots, physically distinguished by a flipped physical connector to preventing accidental insertion of 5 V cards. Universal cards, which can operate on either voltage, have two notches"
- The last, but not least, is the card itself. If the card has a fuse, it might have blown (Digidesign Disk IO cards come to mind). If not, probably some components needs replacing (electrolytic caps...)
Hope this helps!
