iM 4,1-14,4 EnableGop: Pre-OpenCore GOP support for EFI-era iMacs and Mac Pros

[OldMacPro2]

I finally got around to Enable GOP on my Mac Pro 4,1 (flashed to 5,1).

Followed the video on YouTube from Mac Sound Solutions. He walks through it very carefullly and it worked!

With a Radeon VII once I flash the vbios with the one posted on post #674 would that be it or would I still need to follow the complete guide. I am sorry but it seems like its a bios flash and that's it but I want to confirm and it's a bit confusing to me. Apologies in advance. I tried searching this thread but way to much information up and over my head.

You still need to follow the guide as well.

I'm not sure whether there's even space in that VBIOS for EnableGop without further mods, but in any event it's a MacPro card, and the normal, 'recommended' (i.e. it's up to you, but probably most useful) method for the MacPro is to put EnableGop in the main machine BIOS not VBIOS. (The opposite is true for supported iMacs.)
