trying to create a dsdt for an asrock z77 extreme4, but when I click the patch button my mobo is not listed. Is the z77 extreme4 no supported at all? If there are no patches available is there nothing to do then with MaciASL?
If you don't have internet on your Hackintosh, you can copy the patch from another Mac and save as a text clipping. Then move the file over to your Hackintosh. From MaciASL, you can open a patch from a repository OR a text clipping.
I don't remember if the PJALM patch for that motherboard enables HDMI sound. If it does not, you can use either PJALM's graphics patch or Toleda's HDMI patch.
