Hi guys, Lordadmiral Drake is back in the Radeon scene.

I got a new laptop for Christmas and have now set it up with Mountain Lion

It's an Acer Aspire 7750G with 2GHz Core i7 and AMD Radeon HD6850M card.

from red sock_bios_decoder I get:


BR039168.009:

Acer Compal JE70 HR Granville Pro DDR3 64Mx16/128Mx16 4CH

and from radeon_bios_decode I get:

I'm using Framebuffer Uakari in AMD5000Controller.kext and have inserted device/vendor ID there and in AMDRadeonAccelerator.kext under Juniper (RV840 chip).
I also patched my DSDT and added Dual-Link code to GFX0

But when I boot up with GraphicsEnabler=Yes -v the system, despite fully booting up, doesn't switch to desktop but stays at console output. I also dont see any monitors / connectors in System Profiler

[mendietinha]

thats some nice topic. ill folllow. good luck.

[Lordadmiral Drake]

Tried changing control flags from 40 00 to 00 01. No change

[mendietinha]

how do i add dual link to gfx0 and what framebuffer you recomend for the 7650m, just a rebrand of the 6630m?

many thanks! my card isnt recognized by model yet.

edit: put the dual link too.

[mendietinha]

doing some progress here!

i think cosmetic for now, but ill keep going... all the right kexts load normally. amdacelerator, amd6000controller, amdsuport agpm etc...


lets see...

edit: inject vram, rom, framebuffer, disable hd4000, make it work together? the agpm recognizes and apears in the -v boot saying about the board, because i change the 6741 of 6630m to 6841 from 7650m. and it loads properly only using smbios mbp 8.2. otherwise says unknown.


any help here willl be fantastic. i change dsdt, agpm, boot, aty...

good hack

[Lordadmiral Drake]

Success! It works!

I updated OS X to 10.8.2, applied the exactly same patches to AMDRadeonAccelerator.kext and AMD5000Controller.kext as before, rebooted, and go fully working graphics

[mendietinha]

congrats!

is that all you`ve done?

"I'm using Framebuffer Uakari in AMD5000Controller.kext and have inserted device/vendor ID there and in AMDRadeonAccelerator.kext under Juniper (RV840 chip).
I also patched my DSDT and added Dual-Link code to GFX0"
