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

Subsystem Vendor ID: 1025

Subsystem ID: 50e

Router Object Table Offset: 0

Encoder Object Table Offset: 99

Connector Object Id [14] which is [LVDS]

encoder obj id [0x1e] which is [iNTERNAL_UNIPHY (osx txmit 0x10 [duallink 0x0] enc 0x0)] linkb: false

Connector Object Id [12] which is [HDMI_TYPE_A]

encoder obj id [0x20] which is [iNTERNAL_UNIPHY1 (osx txmit 0x11 [duallink 0x1] enc 0x2)] linkb: false

Connector Object Id [5] which is [VGA]

encoder obj id [0x15] which is [iNTERNAL_KLDSCP_DAC1 (osx txmit 0x00 enc 0x10?)] linkb: false

and from radeon_bios_decode I get:

 

 

ATOM BIOS Rom:

SubsystemVendorID: 0x1025 SubsystemID: 0x050e

IOBaseAddress: 0x3000

Filename: BR039168.009

BIOS Bootup Message:

Connector at index 0

Type [@offset 45306]: LVDS (7)

Encoder [@offset 45310]: INTERNAL_UNIPHY (0x1e)

This leads me to following configuration:

 

 

02000000400000000901000010000003 LVDS

00080000000200000001000011020101 HDMI

10000000100000000001000000100205 VGA

 

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

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.

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...

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).

because i think i can have success too after the official ati 7xxx support.

 

thanks!
