Can someone point me to a good tutorial on how to get PCIE cards to work at the same time I have searched around found a couple of tutorials Involving EFI Strings but it always ends with a kernel panic.

2.40 GHz Intel Quad Core
Asus P5K-Deluxe
8Gb PC2-6400 RAM
PNY NVidia 8800 GT 512Mb With CI/QE
PNY NVidia 8600 GT 256Mb

I have also tried this with a NVidia 7900GS 256Mb and a NVidia 8500 GT 256Mb in place of the 8600 GT all work happily together on windows.

Here is my plist generated by EFI Studio:

Here is the Kernel PanicSorry Taken With a camera phone) Any help would be apeciated

Never mind I figured out a different solution I made a custom dsdt file that made it possible without EFI strings.
