Try adding npci=0x2000 or npci=0x3000.

I solved this issue on my parents' build by using "GraphicsEnabler=Yes, IGPEnabler=No" at boot. Just GraphicsEnabler=Yes was not enough to do the trick for me. Hope this helps someone else in the same situation.

Wanted to let people know that this solution worked for me.

Laptop questions should be asked in one of the laptop forums.

Thanks for this!!!

It worked first time for me with my EVGA GTX 460 SE.

I have an Asus Z97A 1150 Motherboard with a i7-4790 processor, and 16GB (4x4) Corsair Vengeance 1866 MHZ Memory. If that helps anybody...

I forgot to mention that after I installed Mavericks...

I had to omit the IGPEnabler=No at boot otherwise I would get Kernel Panic...

Once I installed Multibeast the boot options allowed me to just enable GraphicsEnabler=Yes at boot and all was fine with the world!!!

I got the system to boot with:
Code:
-v PCIRootUID=0 GraphicsEnabler=Yes IGPEnabler=No

many thanks! :)
