I successfully installed Lion 10.7.2 on my Asus P8H67-V, with Sound and Network working so far (can't be bothered at the moment with Sleep and USB3, first want to get my graphics up and running)

For this build I used iAtkos L2 10.7.2, without selecting anything before installation.

Unfortunately after the install, when I tried to boot, it loaded (showed the Apple logo) and after a while totally went black and stayed that way (screen lost signal). Initially I though there was something wrong with the build, but then realized it could be my graphics card, which indeed was the case. So I removed the Sapphire, started up with success and installed all the drivers etc. When it was time to install my graphics card, I located a 6870 kext on osx86.net (well 4 kexts in one file actually - ATI6000Controller, ATIFramebuffer, ATISupport and ATY_Init). I installed via Kext Wizard and shutdown my mac, plugged in the Sapphire and started-up. Only problem is, black screen again.

I tried: "GraphicsEnabler=Yes" and "PCIRootUID=1", but still no joy.

I saw that all XFX 6870 are supported natively, but currently I have a Sapphire (can't imagine that the two is that much different). Does somebody perhaps have a solution for me or any advice?

I would appreciate if very much :wink2:

Kind Regards

you could try changing the frame buffer at boot screen type in. AtiConfig=(then the frame buffer.) here are some to try

Pithecia, Bulrushes, Cattail, Hydrilla, Duckweed, Fanwort, Elodea, Kudzu,
Gibba, Lotus, Ipomoea, Muskgrass, Juncus and Osmunda.
