I successfully installed iAtkos ML2 (10.8.2) with Nvidia drivers disabled (installing with them enabled resulted in a blank screen after installation reboot.) Everything works well out of the box except the graphics card which I can't get to work correctly.
I tried installing Nvidia 304.00.05f02 drivers for 10.8.2, but upon reboot the screen goes black (no signal) after Apple logo. I tried a couple of combinations of these bootflags, but no luck so far (-x -v PCIRootUID=0/1 PciRoot=0/1 npci=0x2000 GraphicsEnabler=Yes/No.)
Without the drivers I'm stuck at 1024x768 resolution and really bad graphics performance sometimes resulting in freezes (e.g. when I open Top Sites in Safari, Safari starts flickering and I get the infamous beachball.) Chameleon (right before the boot) shows my card as VESA 3.0 14MB.
Here's my system info: Intel Core i5 655k AsRock P55 PRO/USB3 PointofView GTX275 896MB 4GB Corsair Dominator 1600GHz RAM and I guess that's all that's important.
Note that the GPU is inserted in the second PCIE slot (x4) as the first one got damaged awhile ago.
Any and all help would be appreciated. Thank you.
