HD6450 recognized as HD 7470 Sierra

[caes95]

Hello, Im trying to get my HD 6450 works on Sierra 10.12.6 but no lucks, so I need a bit help.

 

My card device id on Windows is (0x6778) also the same on OS X without faking it.

 

I´ve tried Clover´s new option RadeonDeInit and the graphics card is not even recognized (Display 4MB).

 

If I set the FB to Bulrushes with Inject ATI option, the system read my card as a ( AMD Radeon HD 7470 4 MB) but still no graphics acceleration.

 

I´ve tried this fakeID (0x67791002) that according to this correspond to HD6450  but the system goes to black screen at booting.

 

My system kext doesn't have any 0x6778 device id specified:

cat /System/Library/Extensions/AMD6000Controller.kext/Contents/Info.plist | grep "0x6779"
<string>0x67681002 0x67701002 0x67791002 0x67601002 0x67611002 0x67501002 0x67581002 0x67591002 0x67401002 0x67411002 0x67451002 0x67381002 0x67391002 0x67201002 0x67221002 0x67181002 0x67191002 0x68401002 0x68411002 0x67041002</string

I have HD6450 with DeviceID=6779. Inject->Radeon=false

I set in BIOS IGPU primary and PCIe secondary. Both to monitor connected. CSM enabled. 

Clover started on IGPU screen, then it go black and Radeon monitor lights on. The macOS 10.12.6 arrived on that screen! Sleep-Wake works fine.

No Lilu, No WhateverGreen, RadeonDeInit not influences in this case.

For your 6778 I may propose to set FakeID=0x67791002 and DSDT FixDisplay=yes. 

 

If I set Radeon to be primary then RadeonDeInit=true. It works!

Sorry for the delay, I've enabled CSM and set IGPU to primary in bios, clover now recognized both cards and it boot in the igpu monitor, but then the system also boot with the igpu and the radeon monitor keeps off. This is with the fakeid you've proposed and with the FixDisplay DSDT.
