I’ve been wanting to do this for awhile but never really built up the motivation to try. I gave it ago this weekend and actually came out with a decent result. I managed to get my AMD Phenom II 940 Black, on an ATI Gigabyte Motherboard, with a GeForce 8600 GT (Yes I had to put away the 260+ since it’s not supported in Leopard… Yet), to boot OS X and run it nicely.
It took a few attempts, and worked out what I needed for the IPC install. The graphics drivers were the hardest to work out, as there is little documentation on the process, and each distro changes.
How I got full support for my 8600 GT was to download the nVidia drivers from here and then modify the EFI strings for Chameleon using OS x86 Tools. My card has a VGA port and a DVI port, however I had to select DVI-I – DVI-I for it to work.
Sound drivers, wireless drivers (my card shows up as an AirPort, however I don’t think draft N is working), network drivers and display drivers all work seamlessly.
HOWEVER I still have one unresolved problem, screen saver won’t ask for a user name and password when I dis activate it. All in all, it took me a few days to work out how ever worked together, and a lot of debugging, but once I got it running “it just worked”.
For the purposes of Apple INC, I own a copy of Leopard, and the EULA is invalid due to the failure of requiring me to accept the contract when I bought the software from the retailer.
