Ok, can you please confirm what kext I need for audio? LegacyHDA, LegacyAppleHDA or some other? Thank you.

The DSDT edit and the kext I uploaded some time ago... an ONLY that. What HDAEnabler does is it tries to "insert audio into the DSDT" (this is technically incorrect, but it works as an explanation), so the problem is that then you would need a modified LegacyHDA (or AppleHDA) to work with what HDAEnabler injects. So by using the DSDT edit you need 1 kext less, and audio works easier.

In my case, still no sound. LegayHDA and DSDT from page 3, but no way. Maybe some other kext in the extension folder need to be removed?

You need to have NO AUDIO KEXTS except the Legacy HDA I posted. Have you repacked you .mkext (or removed the old one?)

Hi, I have ONLY Legacy HDA with 6 other kext that I need.
In order to build a mkext file, I have used MkextTool.app. Than I have manually put Extension.mkext file on the extra folder. Still no sound. I have also try to boot with -f, still no.
Some last suggestion?

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


Here are my rig

intel i7 920
Asrock X58 Extreme
EVGA 8800gt
12GB OCZ RAM (6 X 2GB)
WD 1TB caviar Leo, WD 2TB, WD 1.5TB
WD 500G (i use carbon copy cloner to backup my leo drive once a week)
Edirol UA-1000 USB
Apple bluetooth Mouse and Keyboard

Great! Are you using all core or just one? I only need a DSDT for that.

Just a few questions/comments
Apart from sleeping, you probably cant restart or shutdown.
Do you have all cores enabled?
Do you have good temps?
Why would you boot in 64b (I doubt you have >32GB of RAM) and doesn't PCEFI 10.6 boot in 64b by default?
Whats the point of NVEnabler and GraphicsEnabler=Yes?
I'm pretty sure we don't need JMicronSATA, since the JMicron chip powers the back eSATA port and maybe something else... I think all the SATA ports are ICH10R. We do have a VIA ATA/Firewire chip thou. This last thing isn't well documented, so I may be wrong.

adrian, what kind of kernel are you using? I just drop the mach_kernel from the empirecd.

Vanilla, that's the whole point of an Intel build... just install OS X and DON'T replace any kernel. If you do, your system may not boot since if the empireEFI cd contains one (I doub't, but can't check right now) it probably also needs its System.kext, which you don't mention copying.
So to make it short: don't mess with kernels on an i7, you don't gain anything and loose a lot.
