What boot flags do I need to use with this DSDT?

Also, what kexts should I be using?




I tried booting with just FakeSMC, lspcidrv, NullCPUPowerManagement and Patched_10.7_AppleRTC.kext.

I unset all my boot flags except for "Use Kernel Cache".


My framebuffer wasn't loaded, and audio wasn't working.


Is this because the DSDT doesn't contain the necessary modifications for GPU and Audio?

(I saw viewtopic.php?f=7&t=326 this post, but I don't know enough about DSDTs to adapt it to my situation.)

I see. is there any difference then between booting with GraphicsEnabler=Yes and injecting the Graphics Card into DSDT?


Here (http://www.insanelymac.com/forum/index. ... pic=282302) you said that I should inject the GPU into DSDT to get it to work in 10.8.


EDIT attached is my ioreg dump, using this (viewtopic.php?f=7&t=10) post.
