Dear Astro,
Get retail Snow Leopard, download Empire EFI (google it) and then boot with Empire EFI with 2gb RAM. After it shows all the hdd, remove the Empire EFI cd and insert the Snow Leopard dvd, wait for 20 seconds and then hit F5, select the Mac DVD and hit enter. Go through the installation and select with minimum software, remove printer support, remove additional languages and install. Remember, you can install the extra software after successful installation.
When Snow Leopard's installation finishes, it might show that installation failed, but actually it is installed 100%. It shows the error because it can't make the partition bootable. Restart after that, remove Snow Leopard dvd, insert Empire EFI cd and boot with it. After successful boot, install the myHack Installer 1.0.1 package (google it) with everything required for your system. And you have your very own Snow Leopard running on your system.

Thanks
