@khoatran,

Hi, I have the same video card and have been trying to at the very minimum get a higher resolution than what I currently get (1024 x 728). You mentioned replacing your boot file with the one in the /root directory? Although MacOSX is based on unix, it does not have a separate /root partition as Unix/Linux, so can you point me where do i find root? I've also tried adding my device id to the two kexts you provided above but i does not give me the option to use text editor to edit the files. If i run:

nano -w ATIRadeonX2000.kext....nano shows a blank/new file? Any suggestions will be greatly appreciated.

Hi

the root directory is / basically your hard drive

Also a .kext is a directory. So if you open it up with nano then it will be empty. Try cd instead of nano

Can someone please help, I have the mobility 4650 (0x94801002).

I cannot get it to work. It tried swapping the kexts attached in this earlier in this dialogue, and also the boot replacement file. But these were not for mobility, and when I changed the device id from 9498 to 9480 it totally crashes.

I have also tried the RadeonHD kext, which replaces the x2000 but that did not seem to work.

In addition, I have edited the boot.plist files which things such as screen resolutions and graphics enable etc.

I set up via Hazard 10.6.6 with ATIFramebuffer for the graphics, and it only works on the default 1024x768 which is useless considering I am used to 1920x1080 on this VAIO FW41MH.

Can anyone please please help, I have been trying this for weeks!

A simple guide with actual kexts that have actually worked on a laptop with the same graphics card, not the desktop sapphire version.

Totally desperate for this to work!!

Many thanks!
