I have troubles installing Mountail Lion GM...
At first i created installation flash drive with Chameleon 2.1 and two kext files (FakeSMS and NullCPU). I don't use DSDT.
On the first installer's boot my monitor goes to standby, all i see is just a blank screen. I checked for solutions on this forum and removed all NVDA*.kext files from S/L/E/. Finally, installer starts in 1024x768 resolution and allows to complete the installtion.
Now i can't manage to run the ASUS ENGTX560 TI DCII TOP videocard. All variants i try don't give me full screen and leave only with 1024x768 resolution. With GraphicsEnabler=Yes it detects as GTX560ti, without it - as 3Mb graphics card. I attached the corresponding screenshots.
I also tried to boot with keys PCIRoot=0/1, npci=0x2/3000, tried another kexts - NVDA ones from DP1, GTX 5xxx Enabler and official nVidia website drivers - without any help.
My config is following:
Asus P8Z68-V Gen3 (latest official bios)
Intel Core i5 2500K
ASUS ENGTX560 TI DCII TOP/2DI/1GD5
