I've been trying to make QE/CI work with no success under 10.9.4 and i'd appreciate any help I can get.

 

The AMD 7990HD Card is actually two 7970 linked in crossfire under the same PCI-bridge.

Since 10.9.4 has native support for 7970 it's logical that at least one gfx should be working (i don't care about the second),

 

I've done before DSDT patches and all kinds of stuff and i've read almost everything related on web but I havn't managed to get it done :( .

 

I have 2 problems that may be connected:

 

1. Cannot fake id on both GFX:

 

I've done some DSDT changes to reflect the 2 GFX cards which share the same pci-bridge and now under p0p2\PEGP i have GFX0 & GFX1 (ioreg dump attached), I've tried to inject to them both a fake device-id with but only 1 (GFX1 - the second) actually changes (under ioreg) and the first stays the same and I get no QI/CE.

 

I've tried the same with using Clover FakeID - but the same results.

 

It looks like OSX looks on the first GFX while the injections happens on the second ( the system shows the 7990 dev id and not the 7970 )

 

2. direct plist patches -> White screen

 

At this point i tried to change the Info.plist on AMD7000Controller & AMDRadeonx4000 with the 7990 device id (0x679B1002) - but i get white screen after the end of boot (only safe mode works), also tried patching with clover with no success (under debug i get - Not Patched)

 

3. Personality:

I tried to change the personality with the connectors-info but white screen is still there (see attached file "personality & bios dump") , with clover I also get the "Not Patched" (with loading cache).

 

At this point i'm without a clue and I'll appreciate any help .

 

If i'm not clear enough ask and i'll try to be more coherent .

 

I'm attaching my DSDT , Ioreg dump , clover config.plist and my connectors-info changes.

 

THANKS!
