Interesting question, but I don't think any of us here will have the answers.Eidorian said:Ok, here's ANOTHER can of worms. Since we're on EFI now and can boot in Windows. It means our video cards, etc. don't have Open Firmware BIOS. Does that mean ANY "Windows" video card will work as long as OS X has drivers for it? Does OS X even have generic VGA drivers?
PCs don't use EFI. I don't know if a generic AGP/PCIe card can be initialized by EFI, or if the card will need some EFI code to be on-board.
As for OS X, I think we can be fairly certain that Apple will only bundle drivers for cards that Apple sells. If you install a third-party card, they will probably tell you that you'll need a driver from the card's manufacturer - that's what they've historically told customers.
Generic VGA drivers? I'm sure they were developed - they'd be very useful during that time when OS X/Intel was internal-only. But I wouldn't expect them to be bundled with a shipping copy of the system software.
Now, assuming that the Mac firmware (including whatever EFI drivers they include in it) is capable of initializing a generic video card, then there should be no need for more than a device driver, which the card vendors can probably provide, if they are so inclined. If the cards will require special ROM code for EFI, however, then we're back to the same problem that plagued the PPC systems.
