[SOLVED] Sony Vaio VPCF12M1E - i5-520m - nvidia gt 330m - black screen

Hi guys,
i'm trying to install Mountain Lion 10.8 on my VAIO.
I've created a usb pen drive with unibeast on a Mac, put it into my laptop, but i only see the apple logo, neither the loading circle.
In verbose mode after PCI configuration Begin, the screen become black.
DSDT.AML and SSDT.AML not found.
What can i do?

cpu: i5-520m busratio=18
gpu: nvidia 330m


PS: sorry for my english
 
try with PCIRootUID=0
 
PCIRootUID=0, busratio=18, graphicsenabler=no, cpus=4, -f,-x, also i've deleted the ndva kext, but nothing.
the installation does'nt start, it hangs on Pci configuration Begin
 
ncpi=0x2000 and ncpi=0x3000....nothing :(
 
you should not delete the nvda kexts from the installer and type only -v PCIRootUID=0 at boot. I also had the same problem.
 
I did what you're saying, 3 days ago, it didn't start. :(
 
oH thank you, something move, it don't stuck on PciConfigurationBegin anymore, but black screen is always there.
 
OK, thanks. I'll try , try and try, but at the end i can do it, after all it has only been three days since I got this insane idea. :)
