A fix for GMA950 and GMAX3100 Video Chipsets
Type these exactly as shown but substitute leopard for whatever you labeled your install drive while formatting it and note that all the commands are case sensitive.
Let's make sure you are in the correct directory, type:
You should see a bunch of files with GMA in them such as 'AppleIntelGMA950.kext' if not you are not in the correct directory, you may have to scroll up/down to see them, if not try the first command again and check for the files, once you have verified you are in the correct directory then type:
You will not really see anything happen so lets check to see if the files were deleted, type:
You should not see any files that start with 'AppleIntel', if this is the case then we can proceed, type:
You will see the diskutil start and it will tell you when it has finished along with any errors it has fixed. Now we can close the 'Terminal' utility, you may notice that no option to exit the install is present so just hold your power key for about 4-5 seconds and the PC/Laptop will power down, now restart the system without the install DVD in the drive. Assuming everything went well you should now be able to answer the questions to create an account and register the system. When completed the desktop should load using the VESA mode of 1024x768 while this allows you to use OS X it's not the proper resolution and hardware acceleration will not be functional.
Enabling a specific resolution and hardware acceleration for the GMAX3100
If using a USB memory stick you'll need to copy the files to the local disk first, if you downloaded the files with Safari then you simply Double-click each file to start the unzip process and repeat until all three files are uncompressed. We need to install 'SwitchResX' first, install it by double clicking the extracted file 'SwitchResX Installer' follow the prompts to complete the install and when completed it should launch automatically, if not it can be accessed through the 'System preferences' panel located on the taskbar it looks like this icon.
Next open the 'Kext helper b7' program by double clicking it, a small window will open, you need drag the 6 files (listed below) under the 'AppleIntelGMAX3100' folder that you extracted earlier onto the 'Kext Helper b7' window, if done correctly you should see these files in the window (the paths will proceed the file names):
Enter your password (the one you entered to create your account) into the correct Box near the bottom of the window and press the [Easy Install] button, if everything worked you should see a message saying that everything looks fine please reboot, so feel free to reboot. Note: after you reboot if you have the same issue as before then simply repeat the steps above to delete the 'AppleIntel*' files and you should be able to use VESA mode once more.
