the same way as we install vista on our mac pro
can i install osx86 (that come with bios kernel)
and then using bios-based VGA card (such as HD4870, 9800 GTX+)
on my mac pro in OSX86
Why we can use bios-based graphic card on mac pro under windows vista ?the macpro does not have bios and osx86 doesnt provide bios. thats a feature of the motherboard
what about just installing the nvidia inject drivers? i dont know which one will work for the 9-series.

The boot manager loads before the actual firmware, and when windows is selected, it loads a BIOS Compatibility Support Module.Why we can use bios-based graphic card on mac pro under windows vista ?
if mac pro have something like bios emulator, i'm think we can use bios-based VGA card , because OSX86 boot with bios (Darwin boot loader or PC-EFI that emulate EFI)The boot manager loads before the actual firmware, and when windows is selected, it loads a BIOS Compatibility Support Module.
aka BIOS Emulation. Easier to say.![]()

can someone with mac pro and installed bios-based VGA card proof it
mac pro 3rd party VGA theory
EFI Firmware -> Vanilla OSX <== Normal boot os x
Bios -> Darwin bootloader -> OSX86 <== OSX86 with Hacked Kernel
Bios -> Darwin bootloader -> PC-EFI -> OSX86 <== with vanila Kernel
EFI -> something like bios emulator -> Darwin bootloader -> OSX86 <== Happy using bios-based VGA
As it's the other way around, I'm not sure they would go for trying it. I wouldn't think many have access to Mac, compared to those with PC access.That'd be a really nice thing if the OSX86 community produced a BIOS emulator so that you authentic Mac guys could have more freedom with respect to hardware upgrades.
I do think this is possible using Intel firmware, but I'm not sure if many people would be willing to try it.I'm not expert here but I wonder if there is a way to overwrite the EFI code on the motherboard and replace it with BIOS code from a similar Intel motherboard. Then, you could essentially treat a Mac like you would a Hack. You'd have to use a hacked OSX installation image or an EFI emulator. The plus side would be that you would have a lot more freedom with your platform.

Exactly.Understandable. Who wants to risk killing an authentic Mac board.![]()
Does Windows 7 use EFI?
It would be great if PC cards all had EFI firmware.
