II. The Procedure of installation, ASUS P7P55D is also similar.1. Requirement: Voodoo base 9.8.0 (Qoopz) / 10.5.6 Retail / Boot-132 / chameleon boot loader / dsmos.kext (10.5.8), 2. 10.5.6 Retail DVD Image with voodoo Kernel.3. Boot-132 or Chameleon for Booting.4. As you know, vanilla kernel does not work until 10.6.2 5. S-ATA Mode change to AHCI. 6. Boot-132 7. Need boot option to install as following. 8. "busratio = 20"needed, it sometimes need "cpus = 1" 9. After installing, need to replace the existing mach_kernerl with Voodoo Kernel.
PS: 1. Basically the main board support the internal LAN card, Realtek 8111D. 2. Audio is ALC888. Apple + HDApatch ALC888.txt. 3. EFI-String for graphics card. 4. Rebooting Issue should be resolved by OpenHaltRestart.kext. 4. I recommend you install 10.6.2, Snow Leopard.
