To Conradolpz,
I have the same system and have got a bootable version using Clover. I installed the Mac OS using standard bios and Unibeast. Then when I got the system running I installed Clover to the macos drive. Without Clover, the system had some bizarre timing that caused time to increment one minute every 5 seconds. It was a bear to use as key board repeat was also speed up. Once on Clover I hdd to play around with Clover to get qe/qi video acceleration working (thank you Rehabman). Now I am trying to get sound, battery, lcd and keyboard backlighting control, and battery management.
Have you figured how to patch the dsdt to get these things working?
Can you share the patches if you have been successful?
Rehabman has been helping me, but if you have solved any of these already, I would rather not reinvent the wheel.
Thanks,
Frank
