Hey everybody,

I am attempting to get my ATI Mobility Radeon 7970M working in Mac OS X. I am using an Alienware M17x R4. Buri frame buffer looks like it has the most promise, so let us begin there:

Connections on this system:  LVDS, HDMI IN, HDMI OUT, VGA, DisplayPort
The system is equipped with a muxless switchable graphics scheme, with the option of running Intel only or ATI only.
Am I correct in assuming that the first two "unknown" connector objects are LVDS?
 
First line from Buri Framebuffer

02 00 00 00 00 01 00 00 29 05 01 00 10 00 05 05

 
Suggested patch for LVDS

02 00 00 00 40 00 00 00 29 05 00 00 10 00 00 05

 

Here is the current condition:

With graphics enabler=no, I can boot in limited graphics (1920x1080), no option to change resolution, so I assume no frame buffer is being loaded. Graphics enabler =yes never gets me to the desktop. In verbose mode, it only stays on verbose text. 

 

Kexts that are loaded:

AMDX4000

AMDsupport

 

Kexts not loaded:

AMD7000controller

AMDFramebuffer

 

Device ID is 0x6800, 0x1002. This ID natively exists in AMD7000Controller and AMDX4000

 

Where do I proceed from here? Thanks in advance for info.

 

Also, in my DSDT, I had sections for PEG0, PEGP, and GFX0. GFX0 was renamed to IGP since it pointed to the intel HD 4000, which is fully working. I read other posts online, and decided to delete PEGP from DSDT and rename PEG0 to PEGP and inject my code there. DSDT code is below, please advise.

If Clover hangs on verbose then u are suing wrong drivers.

u have insyde bios soo u need to use lowmemfix drivers and not aptiofix.

Try like that and about draphics injector it must true.

Loadvbios=true + inject edid=true.

Wouldn't generate a dump. I've gone back to chameleon for now. I have included a screenshot of what goes on when using stock kext. no LVDS, but backlight is on + blackscreen. HDMI works, managed to take IOReg dump and two screenshots.

EDIT

replaced modified controller with stock, and clover booted with your config file, but it booted to black screen. No injection yielded same results as before, not being able to boot at all.

We have the same system and card. Booting to a black screen is a good thing for me! when it gets tot the black screen i hit fn+F1 to suspend the system. It puts itself to sleep and automatically wakes (still with a black internal screen), but if you plug in a HDMI the external hdmi works 100% QE/CI, well at least for me it does. Give it a try.

 

Also whats your systems specs? i could send you my dsdt if similar! If you wouldn't mind, could you check out my topic on the internal screen, need a bit of help with personality editing!

 

Cheers!

Without any modification, yes, I have internal black screen and full qe/ci on HDMI as well.  I am running an Alienware M17x R4 with 3720QM, 16GB ram, 1920x1080 display, AR9280 wifi, and Ati mobility radeon 7970M gfx.

Unfortunately, I won't be of much help for you until I figure out my own screen. Follow rampagedev's guide as well as bcc9, it is what I am doing.

Previously my internal screen would present a black screen., but I would also have full qe/ci just like you. I have flashed my bios with an unlocked version and have disabled the integrated graphics. And with a modified amd7000controller kext I am able to get the internal screen working without qe/ci. Have you tried unlocking your bios, in order to disable they integrated graphics?
