I installed os x with [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] and [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] using the guide in this link.

I used the boot file from this guide which I have been using as a basic install guide while not using the .rom file since it doesnt relate to my card, as well as discarding the com.apple.Boot.plist editing.

 

I have installed and have 10.6.7 booting up with out -x, but I had to remove ATIRadeonX200.kext and ATI4800Controller.kext from /s/l/e or it will boot up with a black screen with digitized white pattern across the screen. I added my device id 0x945a1002 to plist of 4800controller, and I have tried using only the RadeonHD.kext only with it freezing at the boot screen.

 

I am new to the os x scene and have been reading around the forums quite a bit looking for guidance. I tried following some of the mobility 4xxx threads but am confused on what I need to do.

 

I am mainly just looking at getting(close at least) to the native resolution of 1920x1200 of my screen. QE/CI would be nice too but I would like it to detect my cards correctly and display the correct resolution.

 

Any help is much appreciated. Thank you.
