I was able to install Mountain Lion on my system by removing the Nvidia GTS 250 and using Intel HD 4000, but whenever I try to use my GTS 250 run the machine (Unibeast or Installed System) I get a black screen and the monitor looses signal.
I have used the card with lion previously but with a different mobo.
I have tried using a different monitor, and each different port on my graphics card.
I followed the information at http://www.tonymacx86.com/108-mountain-lion-installation-tips.html but no luck so far.
I've tried all combinations the following boot options:
-x
GraphicsEnabler=No
PCIRootUID=0/1
I did read somewhere that I may need to replace a kext so that mountain lion would work with older nvidia graphics cards
Specs:
Intel I7 Ivy Bridge 3770
Asus P8z77-V LE
Corsair 2x4GB DD3 1600mhz
PNY Nvidia GTS 250 512mb
Thanks,
MT
