So I've spent days trying to get this to work and it isn't. I have an Asus P5B-Deluxe motherboard and a EVGA 896-P3-1264-AR GeForce GTX 260 SSC Edition 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card .

I installed OS X by formatting my external HD with 2 partitions. I copied my Snow Leopard installer to one partition and installed Snow Leopard to the other. I removed all the NV kexts from /System/Library/Extensions on the installer and used to EmpireEFI to boot the installer. Once it was installed, I booted into Single User Mode and followed http://www.infinitemac.com/f19/guide...leopard-t4057/ of moving the NV kexts. I booted into Snow Leopard ok and ran MyHack from the EmpireEFI disc http://osx86.sojugarden.com/installer/ installing com.apple.Boot.plist, GraphicEnabler, FakeSMC, FramebufferDisabler, JMicronATA, LegacyAppleRTC, NullCPUPowerManagerment, OpeHaltRestart, PlatformUUID, and SleepEnabler. I then ran System Update and updated to 10.6.2 and completed the rest of the guide on getting my GTX 260 working. When I booted I got a kernal panic on SleepEnabler, and realized I needed a newer one for 10.6.2, which I did. Next boot I got a black screen.

So I remove the NV kext's Snow Leopard boots perfectly and everything works great, but if I put them back I get a black screen still. Anyone have any idea why it isn't working? I added the stuff to both my com.apple.Boot.plist in /Library/Prefereces/SytemConfiguration and /Extras.

Thanks!
