OK, I'm getting really stuck. I followed Giacomoleopardo's Guide:
http://www.tonymacx86.com/user-buil...z77-itx-wifi-core-i7-3770t-macmini-6-2-a.html
with the exception that I have disabled Azallia in the BIOS as with it enabled, I can ONLY boot in safe mode.
I have been unable to get HD4000 woking with acceleration.
I did notice that the DSDT edit for the injection of the HD4000 was in the wrong place using the patches mentioned in the guide, so have relocated it under IPGU as per Toleda's guide:
http://www.tonymacx86.com/graphics/...000-hd4000-amd-nvidia-working-together-9.html
EDIT PICNIC Error: The patch put it in the right place, I just can't read properly!
This at least allows me to boot with GE=No, but I HAVE to use the Kernel Cache to boot out of safe mode. Booting with UseKernelCache=No stops after generating a DRMStatus issue which I believe is linked to the injection somehow.
I have tried multiple platform id's on the basis that 0A 00 66 01 "gives" me 768MB VRAM?? My best match appears to be 05 00 62 01 since both HDMI's and the DP work at full res (1920x1080 and 2560x1440 respectively). On that note, Toleda, I believe there to be a typo on post #25 of this thread; under Mobile/Laptop Summary, you listed 09 00 62 01 which results in the HD4000 not being recognised at all. I just get "shared 64mb of graphics memory". I think it should be 09 00 66 01 as listed under detail on that post.
I attach IOReg and the current DSDT and hope someone can help.
For detailled convenience, build is:
Zotac Z77 ITX Wifi - with latest BIOS - no need for patching
IVB i7 3770T
Corsair Low Profile 8GB DDR3 1600 RAM using XMP
SanDisk Extreme 240GB
EDIT I seem to have an issue with IOAcceleratorFamily.kext interfering with something. As in, if I delete it, I can boot without the kernel cache. I
CAN then reinstall and manually load it and the HD4000 kext and get all kexts loaded, but still no QE/CI. I believe this is related to the Capri frame buffer that when it loads gives me a DRMStatus issue
