So i need to edit the other kexts also? I have to: - set framebuffer (Nomascus for this card) - Edit these kexts - Set GraphicsEnabler to Yes Right? The DSDT's patches for Nahelm are universal? (for every notebook\desktop) Thanks.

I know i have to try many times... and it's a probably hard work. But it's ok. Anyway, i've tried to edit the ATI5000Controller, but i saw that there is my video card's device id and vendor id (0x68A11002) already. I've updated Chameleon to the last release "official". (and tried also with Enoch version) I've tried to apply the DSDT patches (Nahelm) I've searched my device id on the kexts section of Olarila... and found many entries. Seem to be compatible, but i don't understand where i made a mistake. Is there a way to identify the origin of the problems? Thank you in advance.

Hi, Thank you for your reply. I've tried with these guide, but nothing changed. The graphic still not work. My errors or hard hardware configuration?

Hi guys. i'm trying to install Mountain Lion 10.8.2 on HP Envy 17 1188-el. I've encountered many problems with clean retail install, so i've tried with iAtkos Ml2 and it work... but not all, it's just a very basic system without many features. I've tried also different bootloaders, kexts and utility... without success. Who can help me? I've darwindumper reports, are useful?
