First download this Package i made and move it to an ext HDD or burn on CD. (90MB - SL Extensions Backup Included, Hence the Size)

Download:

Empire EFI V1.07R2

Burn it on a cd.
Boot your pc with the cd in the drive.
When you see Darth Vader, eject Empire EFI cd and insert SL RETAIL DVD.
Wait few seconds and press F5 and you should be in the installer after few minutes.
After OSX Install has loaded:
-
- Choose language and click on the arrow.
- Click on Utilities on the tool bar, then select Disk Utilities.
- On the left you should see your hard drive.
- If not, a disk is not connected or cannot be read by your computer.
- After selecting your hard drive click on Partition.
- Under Volume Scheme, click current and select 1 partition.
- Under Volume Information, name your hard drive.
- Format: Free Space
- Click Apply
- Click Partition
- After selecting your hard drive click on Partition.
- Under Volume Scheme, click current and select 1 partition.
- Under Volume Information, name your hard drive.
- Format: Mac OS Extended (Journaled)
- At the bottom of the window Click on the Options Button.
- Select the GUID Partition Table
- Click OK
- Click Apply
- Click Partition
- Quit Disk Utilities
- Click on the HDD you want to install OSX to.
- Select customize, deselect printers and languages from the list.
- Install OSX.
- Restart.
-
Use Empire EFI cd and boot into OSX HDD.
When you are in OSX, extract and mount my package.
Install Chameleon:
_
- Extract / Mount my Package.
- Go to folder Chameleon.
- Extract Chameleon Installer.
- Install chameleon package but don't press restart.
- Extract / Mount "Extra.dmg" from Chameleon folder.
- Copy the Extra folder and go to the root of your HDD.
- Paste the Extra folder there [Replace existing Extra folder]
_
Restart.
Boot with arch=i386 -v
Install Kexts:
_
- Copy the kexts from the folders Ethernet, Graphics & Sound in my package into S/L/E.
_
Use Terminal to repair permissions.

sudo chmod -R 755 /System/Library/Extensions
sudo chown -R 0:0 /System/Library/Extensions
sudo kextcache -v 1 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions/

After restart you should have it working , also you should have native resolution but no QE/CI!

Hardware:

Sound - Kinda Works
Ethernet - Works
Wifi - Does not work
GFX - Works partial, no QE/CI
Touchpad/Keyboard - Works
Built in Webcam - Not Tested
SD card reader - Not Tested
Sleep - Not Tested
Time Machine - Not Tested

Notes:

Sound - With VodooHDA you will have crappy sound that will turn into normal as long as you move the mouse, i tried to convert Leo AppleHDA to SL but did not work, probably needs DSDT patching and i'm not good at that.

GFX - Card not supported so you will have no QE/CI, but you will have native resolution thanks to the patched RadeonHD.kext

Wifi - AR5007 will get recognized but will say HAL Status 13, it is because it shares same id's with AR5006 which is supported and will try to load drivers for it but will fail.

Webcam- Recognized as USB webcam in profiler but i dunno if works.

When booting to x64 mode AppleATIATA will not load so it will get stuck there.

Tip:

* Buy an D-Link DWL-G122 USB Wifi Adapter (~30$) which works using Ralink Drivers for SL or D-Link drivers for Leo.

* Buy an EDIMAX EW-7711UTn USB Wifi Adapter (~30$) which works using Ralink Drivers for SL.

* I have included drivers for both in the package.

For permanent x32 mode:

Edit com.apple.boot.plist
Add:
<key>Kernel Flags</key>
<string>arch=i386 -v</string>

Have fun
