Specs

• ASUS P5N-E SLI Motherboard

• Western Digital Caviar Blue Hard Drive

What you’ll need

• Snow Leopard
• Empire EFI
• IDE DVD Drive (SATA Drive’s won’t work, it will stall with “Still waiting for root device”)

Instructions

1. Burn Empire EFI Legacy (iBoot may also work using this method)
2. Boot Empire EFI
3. Remove Empire EFI from the DVD Drive. Insert Snow Leopard and press F5
4. Press Enter to boot the Snow Leopard Installer
5. Partition and format the hard drive then install Snow Leopard as normal
6. When the installation is complete, remove Snow Leopard and re-insert Empire EFI into the DVD Drive
7. Boot Empire EFI again. Select Snow Leopard and press Enter
8. Follow the iBoot guide to install 10.6.8 combo update
9. During MultiBeast setup, select the following:
   • EasyBeast
   • System Utilities
   • FakeSMC
   • IOUSBFamily Rollback
   • JMicron ATA
   • PCIRootUID=1 Fix
   • GraphicsEnabler=Yes
10. DO NOT REBOOT! Install AppleNForceATA.kext to /Extras/Extensions
11. Run: sudo chown -R root:wheel /Extras/Extensions/*
12. Now run /Applications/Kext Utility.app
13. Reboot and enjoy OS X 10.6.8!

You should now have working ethernet, and dual screen monitor support. I’ve yet to get my SATA DVD Drive to function.
