I have the Gigabyte Brix GB-BXI5H-5200 unit. Currently I have completed Step 6 of this guide, and I do not have audio or Wifi at this time.
I'm not sure which EFI folder is correct to download because my Brix uses laptop RAM, but I tried both of the Broadwell ones and neither gave me audio. I downloaded them, and then moved them from my Downloads folder into the /Volumes folder, creating /Volumes/EFI (which was not already there).
(Section 7a - Video Patch) My device has an Intel HD 4400, but I can't understand this part at all. I just don't get what I'm supposed to do there.
(Section 7b - Embedded Controller Device) - I don't understand this section. Can someone explain what any part of that means for me?
Any help is appreciated.
