UGA driver?

If you can tell me how to get it off my mbp I can help :)

I've been trying to dump the rom too, but without success, not through windows and OS X.. :/

if you want the EFI rom of the 8600, you'll have to use nvflash to dump it.
if you want the bios rom of the 8600, you can get in in the Apple Restoration CD 1.3

if you want to dump them from linux in legacy mode (when using elilo, the vgabios will not be available), just type, as root:

dd if=/dev/mem of=vga.rom bs=1k skip=768 count=64
(64kb starting from 0xc0000)
In the case the rom is 128k, it means it contains two option roms (one bios, one efi), like the 7300GT and the quadro 4500, but only the bios one will be mapped to 0xc0000, to dump the efi one, you'll need to use nvflash instead.

dd if=/dev/mem of=efi.img bs=1M skip=4094 count=2
(2MB from top of memory)

I have found this on Wikipedia:

Video
For connecting displays, Apple used a DA-15 connector on all models prior to the Power Macintosh G3 (Blue & White), which used a VGA connector. The original AGP-based Power Mac G4 used VGA, complemented by a DVI port; almost all later Macs, however, used the Apple Display Connector in addition to a VGA or DVI port, until the last revisions of the Power Mac G5 came standard with two DVI ports. All current Macs now have one or more DVI ports. Apple includes DVI-to-VGA adapters with its computers.
While not user-accessible, the 24-inch iMac features an MXM-formfactor video card; however, there are no upgrades available for it. Video cards can be replaced by the user in a Power Mac (which used PCI; later, AGP; finally, PCIe) or the Mac Pro (which has four PCIe slots). In all other Macs, the video card is integrated with the logic board and cannot be replaced.
PowerPC-based Macs, for the most part, required compatible video cards. The current Intel-based Macs can use any EFI-compatible video card; normal PC video cards will work only if the user boots into Microsoft Windows. Some hackers, however, have found success "flashing" PC cards to work with Mac OS X in Apple's hardware.


So will be PC-video cards working with EFI?
I'v heard that the most video card have efi rom,
but the wiki article bewilders.

Hi,

According to the EFI CSM spec, a video card with a BIOS rom can work with a EFI OS. It "just" depends on two things:
- your EFI OS loader has to load the legacy rom (using the InstallPciRom EFI function),
- your EFI OS has to provide a driver for it (and MacOS X is not really known for its wide range of supported devices).
