hi all, I'm struggling to add a UEFI Bios so I can get a boot picker on this Mac Pro 3.1. It's currently F1 bios, Gigabyte say F1-F9 should work but F3 flashing complains of sub system ID mismatch and fails.
I've tried extracting and injecting a UEFI using HD7xxxSeriesUEFIPatchToolBETA which seems to work but wrecks Mac OS HDMI display, I also tried Netkas' 7950 script to add a Mac EFI picker which worked with the loss of HDMI and DVI Catalina OS up.
It seems a shame to give up on this card for want of a boot picker as it's otherwise perfectly adequate for my needs. Any insight would be much appreciated.
