Firewire PCI card not seen by El Capitan

[Mystroe]

Interesting wrinkle to my issue: I bought a StarTech PCI1394MP (so not a PCIe card, but a PCI) that I read worked in other builds. When I installed it in one PCI slot, nothing. But when I tried my other PCI slot I could no longer boot up with the nVidia graphics driver running. Take the card out and it boots up again like a champ.

This FireWire issue is that last little thing I need to fix to make this a workable machine for me. And it's necessary, as the whole purpose to run a Mac OS on this hardware is for a more stable Pro Tools setup with my Mbox 3 Pro that only connects via FireWire. It's so close I can taste it!
