4everAnoob Posted November 16, 2014 Author Share Posted November 16, 2014 [HOW TO] Make Radeon {Desktop or Mobility} be working by using Clover 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?

4everAnoob Posted June 20, 2015 Author Share Posted June 20, 2015 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! Link to comment Share on other sites More sharing options...

ftenab Posted May 19, 2017 Share Posted May 19, 2017 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.

Test also the DP codes extracted from Cattail framebuffer, so originally my DP connector was fully working with cattail without patches. Link to comment Share on other sites More sharing options...
