carbo178 Posted December 16, 2015 Share Posted December 16, 2015 Try FB injection from 0x16160002 to 0x16160000 or 0x16260006 If doesn't work you should extract and patch dsdt Link to comment Share on other sites More sharing options...
David-Tripa Posted December 16, 2015 Author Share Posted December 16, 2015 Hi carbo178, Thank you very much for your reply. Could you please brief me? What is FB injection and how do I go about doing it? And if that doesn't work how do I extract the DSDT? Will you be able to patch it for me, or do I have to do it? If I have to patch it, how do I do it? Thanks Link to comment Share on other sites More sharing options...

carbo178 Posted December 17, 2015 Share Posted December 17, 2015 Try to change amount of video ram, step by step until 512mb Link to comment Share on other sites More sharing options...
David-Tripa Posted December 17, 2015 Author Share Posted December 17, 2015 Hi carbo178, Which video ram must I change? The DVMT pre-allocated (My one can go from 32MB to 2048MB) or the DVMT Total GFX MEM (which is set to 256MB)? Must I use your config.plist (The one you attached previously)? Please also see attached screenshots of my S/L/E folder and tell me if I must remove or replace some of these kexts. Thank you for your help.

carbo178 Posted December 17, 2015 Share Posted December 17, 2015 Don't remove any kext, i suppose if installed kexts are from vanilla system Modify DVMT pre-allocated Link to comment Share on other sites More sharing options...
David-Tripa Posted December 17, 2015 Author Share Posted December 17, 2015 Hi carbo178, Thank you for your reply. Before I change my config.plist and modify my DVMT pre-allocated from 32MB to 512MB, I would like you to first see the message I get when I boot my PC in verbose mode with my working config.plist which boots up: [iGPU] Graphics driver failed to load: could not register with Framebuffer driver! Please also see attached screenshot and advise. Thank you for your help Link to comment Share on other sites More sharing options...

David-Tripa Posted December 17, 2015 Author Share Posted December 17, 2015 Hi carbo178, Must I try your config.plist from Post #34? Must I try it from 32MB to 512MB DVMT pre-allocated? Thanks Link to comment Share on other sites More sharing options...

David-Tripa Posted December 20, 2015 Author Share Posted December 20, 2015 Hi carbo178, Thank you for all your help. I did set my BIOS settings like the one in the guide you gave me, and I tried the first config.plist, but it did not want to boot up, please see attached error message I get in verbose mode. Please see the first attached screenshot for the config.plist. I also tried the DSDT.aml and I put it in EFI/CLOVER/ACPI/Patched folder and I also replaced the config.plist with the one in that folder, please see the attached error messages I get when I boot in verbose mode. Every time I boot up with that DSDT.aml and that config.plist which was in the same folder with the DSDT, I get a different error message every time. Please see the 2 attached screenshots for the DSDT. Thank you very much for your help. Link to comment Share on other sites More sharing options...
