Could someone plz help get the m5950 (=6770m) working properly?
With clover no matter what it always ends up with 7mb VRAM and corrupted graphics...


Also, my hd6870 shows black screen after about 15 seconds on unigine benchmark. Anyone else have this issue?

Thanks for the reply, however I checked this thread, and I'm still confused.

Because the screen gets detected correctly, meaning EDID is not an issue. In chameleon bootloader screen always stays black.

So you think it is a matter of patching the framebuffer and then the full 1024 mb VRAM will be detected and the card will work properly?

I have all clover options enabled like loadvbios, injectati etc etc.. I havent tried patching framebuffer but the screen works so how will that help?

UPDATE: Old thread, I know, but for anyone else wondering whether this can be done... IT WORKS!

Install with Clover EFI bootloader. Enable the following: InjectATI, Inject EDID and LoadVBIOS. Use "Cattail" for the framebuffer (FBname).

Good luck!

Great! Mine is working too.

 

But did you get VGA output working as well?

I did some trials and succeed. Now full working connector VGA. Also full working DP connector. NO troubles with colours or resolution.

Probably to adjust your DP connector you will need to build your own code (changing mine 11020101), run radeon_bios_decode and redsock_bios_decoder to find yours . 

Test also the DP codes extracted from Cattail framebuffer, so originally my DP connector was fully working with cattail without patches.
