Hey -
I'm trying to install Mountain Lion using Unibeast ( no previous installation, though I used to have SL & Lion on the same machine ) on this computer:
GA-P43T-ES3G
Nvidia GT 430 With 2 monitors in DVI and VGA
4GB Ram
Intel Core 2 Duo @ 2.77Ghz
When I tried to boot normally, I just got the loading screen - white background and apple logo in grey in the middle, and after a while the screen went black.
It's not that the installation is giving a "Black screen" output, it just gives no output at all ( my monitor is saying "No signal could be found" ).
I tried booting with -v to see where it fails, and the black screen occurs when the installation says "PCI CONFIGURATION BEGIN". it hangs for a couple of seconds with that text, than the black screen occurs.
I tried booting with -x, GraphicsEnabler=No, PCIRootUID=0, yet I get the same result on all of those.
I know that there are a couple of problems with the Fermi Nvidia GPUs, but I Thought they were only sleep related, and they should not interrupt the installation.
Anybody knows how to solve this? Also, could I just connect my monitor to my onboard gpu and after the installation is done connect it back to my GPU?
Thank you for the help and have a nice weekend,
Niv.
EDIT:
I came across someone saying to try npci=0x2000 boot flag. When I do this I get the same black screen, only without the PCI Configuration begin before it.
