ATI Radeon HD 7310 on Yosemite/AMD

[schmidt9]

Hello,

I decided to raise this question again dispite this unanswered topic http://www.insanelymac.com/forum/topic/294802-ati-radeon-hd-7310-on-mavericksamd-system/, while I can provide more data, maybe I could get answer, is it generally possible to get QE/CI working with this card.

What I tried:

 

1) Patching framebuffer following this guide: http://www.insanelymac.com/forum/topic/303186-how-to-modification-of-amd-fb-clover-injection/?p=2093026

I've choosen following personality from AMD6000Controller.kext:

Personality: Pondweed
ConnectorInfo count in decimal: 3
Disk offset in decimal 1664784
0000000    02  00  00  00  00  01  00  00  09  01  01  00  10  00  05  05    / Laptop Monitor
0000010    00  04  00  00  04  03  00  00  00  01  02  00  11  02  01  01    / Display Port
0000020    00  04  00  00  04  03  00  00  00  01  03  00  21  03  02  02    / Display Port
0000030

and changed it to

0000000    02  00  00  00  00  01  00  00  09  01  01  00  10  00  01  01 / Laptop Monitor
0000010    00  08  00  00  00  02  00  00  00  01  02  00  20  01  02  02 / HDMI
0000020    10  00  00  00  10  00  00  00  00  01  03  00  00  10  03  08 / VGA

No effect at all (no new info about graphics, no QE/CI)

 

2) Device strings generated in EFI Studio and added to Properties in Clover

I tried various variants, info about graphics card did change, but VRAM size stayed by 4-7 MB, so no success again.

I afraid this is impossible. This chip family Palm is not supported in MacOS.

It's a pity.

Thanks for your help!
