[HOW TO] Modification of AMD FB + Clover injection in ATi Posted October 31, 2016 On my ASUS R9 390 8GB STRIX I got blackscreen after patching it. My motherboard doesn't allow me to select internal graphics as first load when an PCI-E videocard is attached to the board. If I change, save it and reboot, it is auto-detected during post process and it bypass bios information/reading. Then I'm stuck at El Capitan since in Sierra I could just boot into installer, after the installation is completed I don't have video on my screen. In El Capitan my system had some random freezes sometimes(mostly when using intense 3D acceleration). I installed Warcraft 3 and start playing it, everything runs fine for a while and then it freezes. Then I made some tests and if I minimize it and start doing some other task while it still opened, system freeze too, but faster than when I'm just playing it. I had successful boot with FakeID and ATI Injection, but this situation doesn't improve my experience on hackintosh. My only problem is my video card, too bad the driver sucks on OS X and it isn't friendly with R9 390. Also, there is no ramebuffer for my video card(it has 5 ports, 3-DisplayPort, 1-HDMI and 1-DVI-D). Guess I did everything right while searching the right connector output. Maybe somebody could point if I'm doing something wrong? Would like to hear what you guys think. Here is how I did it. I made some edition to Baladi FB with my output that I got from the shell script. Created the patch for the kext on Clover section. Tried to boot with my own hardware ID and with FakeID, using Baladi in the FB section. Tried all the DisplayPorts my video card have, all of them I got black screen(just black screen, it blinks like if there is video, no warning about "no signal" is displayed). I can turn off, login normally, even reboot the system using the keyboard shortcut. Here is what I get from both shell commands. Here is what I understood as the right values I should put in the last 8 digits. Here is how my FB patches looks. Hope someone helps. Thanks.
