thanks for the reply

I know my spec's are really good, thats not why I posted them. I wanted to be clear I was not on AMD, or had a weird video card... That the reason many people have to twiddle about their install.

For instance, netkas released PC Efi 10 based on Chameleon... I thought these two were two completely different methods, first for retail and apple direct upgradeable, the second for multibooting purposes... And with this version 10 it does not load without a dsdt.aml file present... But how do I know if I need it not? How did you find that out?
