GUIDE: GA-Z68MA-D2H-B3 UEFI BIOS - ALL WORKING, DSDT not required!

[neilryan]

UPDATE: I managed to update the BIOS to the UEFI version and also to install High Sierra. I had to use a MS-DOS formatted USB stick and run the flashefi.exe from the stick. Thank you @ghorwith.

How did u do the bios update? I keep getting bios id error. Then i also created a bootable freedos thumbdrive, put the bios file there and ran the exe file. It completed but when i rebooted, i got error again and had to choose last known good configuration. So i am still on f10 bios

Update: managed to flash it again with the freedos bootable thumbrive. Success.

Installed sierra, got all working, even quicksync (i left igpu enabled but used gt 710 gpu in pci lane), hdmi audio works. No usb 3.

Repeated the same steps for High sierra, now hdmi audio and usb 3 do not work.

I5 3570 cpu
Zotac gt 710 gpu
