- Download and Burn the DVD image iAtkos v5i.
- Download and Extract the Bios v5.17 MOD by MACNUT or v5.23 by Kabyl make sure your Motherboard model is Asus IPIBL-LB. If your PC is similar but your motherboard is Asus IPIBL-LA you can try this BIOS Version, this is not a MOD bios but work perfect (Thx, igotjshoe)

Be careful about the BIOS Flashing, if you dont wanna flash the BIOS just try cpus=1 in darwin

- Now go to the Power Tab and Enable the processor's XD Features, Saving and Exit.
- Boot into the DVD by pressing ESC key at the BIOS Prompt and the installer should load now.

How to fix unknown processor string in "About this Mac"

go to System/Library/CoreServices/Resorces/English.lproj

You will find a file "AppleSystemInfo.string" open it using TextMate and find "UnknownCPUKind" = "Unknown";
replace unknown with the type of your processor for example, Intel® Core™2 Quad. make sure you change only letters only not the special characters like =, " or ;. Save it, it will ask for your permission, enter your password and you are all set, no need to reboot.

How to change "About this Mac Graphic"

To use these you need to backup the current MacOSX.tif in /System/Library/CoreServices/loginwindow.app/Contents/Resources and then delete MacOSX.tif

Then rename the file you download to MacOSX.tif and copy it to /System/Library/CoreServices/loginwindow.app/Contents/Resources

Then fix permissions.

Logout and login then view About This Mac.
