Hi.

I have ASROCK Z68 Pro M3 Motherboard (ALC 892) and Sapphire ATI HD 6570 1Gb GDDR3 Silent. I want to try this tutorial for my Graphic Card and HDMI audio.

My first problem it´s that I don´t know my GPU codename to select the correct framebuffer and one more thing.

OpenGL Extension View say:

But in list, don´t find Turks Pro...
 
Framebuffer maps any HD 6xxx GPU to the physical ports.
AMD6000Controller, look for HDMI
Ipomea, Muskgrass, etc. may work

I don´t sure understand you...

Hi,soon i wil get an XFX AMD 7750 card running OS X Yosemite - came from Nvidia GT 440 (chameleon, GE=Yes is enough).

Goal: I only need VGA or DVI output, no HDMI output (with Audio) needed.

Here my radeon_decode output:

GA-EP35:radeon_bios_decode.0.2 andreasm$ ./radeon_bios_decode < /Users/andreasm/Desktop/AMD/radeon_bios_decode.0.2/XFX.HD7750.1024.120514.rom

Has someone Yosemite with that card running?
I can see that newer chameleon have already some config for 7750 in the code (used by GE=yes)

{ 0x683F,0x04231043, CHIP_FAMILY_TAHITI,"Asus HD 7750", kChutoro},
992 { 0x683F,0x04271043, CHIP_FAMILY_TAHITI,"Asus HD 7750", kChutoro},
993 { 0x683F,0x04591043, CHIP_FAMILY_TAHITI,"Asus HD 7750", kChutoro},
994 { 0x683F,0x200B1787, CHIP_FAMILY_TAHITI,"AMD Radeon HD 7750", kChutoro},
995 { 0x683F,0x23181787, CHIP_FAMILY_TAHITI,"Vertex3D HD 7750", kChutoro},
996 { 0x683F,0x25511458, CHIP_FAMILY_TAHITI,"Gigabyte HD 7750", kChutoro},
997 { 0x683F,0x27921462, CHIP_FAMILY_TAHITI,"AMD Radeon HD 7750", kChutoro},
998 { 0x683F,0x2B301002, CHIP_FAMILY_TAHITI,"Ati HD 7750", kChutoro},
999 { 0x683F,0x32411682, CHIP_FAMILY_TAHITI,"XFX HD 7750", kChutoro},
1000 { 0x683F,0x32421682, CHIP_FAMILY_TAHITI,"XFX HD 7750", kChutoro},
1001 { 0x683F,0x32451682, CHIP_FAMILY_TAHITI,"XFX HD 7750", kChutoro},
1002 { 0x683F,0xE2131019, CHIP_FAMILY_TAHITI,"Diamond HD 7750", kChutoro},
1003 { 0x683F,0xE213174B, CHIP_FAMILY_TAHITI,"AMD Radeon HD 7750", kChutoro},
1004 { 0x683F,0xE215174B, CHIP_FAMILY_TAHITI,"Sapphire HD 7750", kChutoro},


I think Chutoro must be the Framebuffer (in ATI7000...kext).

What chameleon boot config should i use?
GE=Yes
or GE=No and some ATIConfig= other Framebuffer than Chutoro , ATiPorts=??

Or must i patch something even i only need VGA/DVI out (one display enough) , no HDMI (audio)?


Thanks!
