"leppys disk only works properly with 10.6.0 as apple upgraded the os leppys disc did not follow with them so some kexts he uses will not load properly like graphics and such because of kernel dependencies. once you have a booting system install edp 1.9 go to your new extra folder on the drive you installed edp to run edptool.command install chameleon to the drive it's one of the options then build edp for your model. and combo update to 10.6.8 once it reboots to 10.6.8 rerun edp for your model again to replace some audio dependencies.
