Install Steps:

1. Boot off of the Boot132 CD.
2. When you get to the Boot prompt, hit enter once.
3. Eject the Boot132 CD.
4. Insert your MacOSX 10.5.6 Leopard DVD.
5. Hit Enter.
6. After the Installer loads, select your language and hit the next arrow.
7. At the Welcome Screen, click on Utilities (at the top of the screen) and select Disk Utility.
8. Select the Drive you are installing OSX on (this is easiest if you only have one drive in at this point).
9. Click the Erase Button and give your drive a name, then click on Erase, click Erase again.
10. Click Disk Utility (upper left hand corner of the screen) and select Quit.
11. Click Continue, click Agree, and then select the drive that you just set up in Disk Utility.
12. Click Continue, and then click Install
13. Click Skip when the Checking DVD screen comes up.
    

    NOTE(S):

    After the install completes, click Finish/Restart. One of two things will happen. Your system will either reboot and NOT boot into OSX or it will hang. Either way, this is normal. Just power off the machine, and then power it back on. After you power it on eject the Leopard DVD and put the Boot132 CD back in and boot from it again. When it gets to the Boot menu, hit enter once. and then continue with the following instructions:

14. Type 80 and hit enter. You should see the drive you set up in Disk Utility.
15. Hit Enter again to verify that is the drive you want to boot from.
16. OSX will now boot, and you will go through the normal configuration screen. Complete the forms as needed.
17. When you are at the desktop, copy the OSX_Tools folder to your desktop (via CD, external drive, etc)
18. Open the OSX_Tools folder, open the Chameleon folder, and install Chameleon.
19. If you have one of the motherboards listed in the DSDT folder, copy the corresponding dsdt.aml file to the root of your hard drive. If not, go to the next step.
20. Open the DSDTPatcher Folder in the OSX_Tools folder. Launch the App in there
21. Select: New HPET Option, and Apply DSDT Patch to: on the right side. Select your OSX Hard Drive from the dropdown menu and click 'Run DSDT Patcher'
    

    NOTE(S):

    You will be prompted for your admin password. Enter it. This will generate the DSDT file that is needed for your motherboard. When it is done:

22. Quit the DSDT Patcher
    

    NOTE(S):

    At any point following, if you are asked to reboot, DO NOT REBOOT, click Cancel.

23. Back in the OSX_Tools Folder, open the OSX86Tools app, and click "Install kexts' - Click OK.
24. Browse to the OSX_Tools folder, open Kext, and select all the kexts (except the RealtekR1000.kext - it isnt needed for the G31M-ES2L board)
25. After the install click "cancel' when it wants to reboot.
26. Click 'Add EFI Strings/Boot Flag'
27. Click on the 'GFX Strings' button, select your card (or custom) and click the 'Import into Boot Editor'
28. In the 'Please enter timeout' area enter a number - I enter 1 personally, but this is the number in seconds the Chameleon bootloader will wait before loading OSX
29. In the 'Please enter the graphics mode' enter your resolution. I enter 1024x768x32 and then change it via the control panel later.
30. Click 'Apple changes to com.apple.Boot.plist' It is writing a new Boot.plist now. It creates a backup one.
31. If asked to reboot, click Cancel
32. Unzip the ALC883-10.5.6_kexts.zip file and install them using OSX86Tools
33. After you have installed the 2 kexts, select 'Set Extensions Permissions' and 'Clear Extensions Cache' and then click 'Run Selected Tasks'
34. When it is completed, reboot.
35. You should now be all running and can now install any updates from Apple Software Update. See below for additional notes.

Final Notes:

• If you try to boot and it freezes or hangs at a blue screen, reboot your machine, and at the Chameleon boot window, hit any hey to prevent it from booting. Follow these steps to restore the original Boot.plist file and get you into the OS so you can tweak any settings:

1. enter: -s and hit enter. This will put you into Single User Mode (command line)
2. enter: mount -uw / (This will put mour the root drive as read/write)
3. enter: cd /Library/Preferences/SystemConfiguration (this will put you in the directory we need)
4. enter: rm com.apple.Boot.plist (this will remove the boot file)
5. enter: cp bootbackup.plist com.apple.Boot.plist (creates a new boot file from the original working one)
6. enter: shutdown -r now (reboot the computer)
