Hi everybody, after about a month of struggle, here is the best and quick way i found to make this work :

Instal OSX snow with Empire EFI CD (about 45mn)
Boot with Empire EFI CD and now select your drive with fresh Snow Leopard
OSX Leo first startup......setup your password and information, (don't worry about the screen resolution at this point....)

Download multibeast installer from tonymacx86 thank's Tony!!!

option that i checked : kext : NVEnabler / JMicronSATA /
IOAHCIBlockStorageInjector

Chameleon : PC-EFI 10.6 by netkas

com.apple.boot.plist : 64-bit apple boot screen

Multibeast install takes about 3mn

Software update => 10.6.3 (about 15mn, it depends on your internet conection)

Before to Reboot open your extra Folder and copy your com.boot.plist on your desktop, open it with text editor, and add this line


<key>Kernel Flags</key>
<string>-force64 GraphicsEnabler=Yes</string>



Save it then copy (overwrite it in your extra folder, (takes about 2mn)


Reboot without empire EFI CD and smile!!!! you should now see the full resolution and then your desktop with fresh Snow Leopard 10.6.3 !!!!

I didn't bother with audio ( i already have an great USB external sound interface with drivers for snow leopard)
I didn't bother with the (sleep) yet, it's not too important to me but i would like to give a try later on

PS : Don't ever try or bother installing OSX on a Hard drive bigger than 1TB
you will face some serious issues installing your bootloader, it's a waste of time

My only question is :

Why should i need a Patched DSDT ? my system is running 24/7 without a crash, my applications run in 32 or 64-bit with 12GB of RAM....
I would love to hear your input as i'm a newbie
