You haven't said what the specific card vendor/model is, but perhaps there's a UEFI capable BIOS on techpowerup: https://www.techpowerup.com/vgabios/?model=GTX+670 > If this doesn't work, I'll look into patching the kernel.

Yes it would help, but then your GTX would become the primary console and you'll need to go through some extra steps to prevent the non-pci drivers from attaching to the video head too. Minimally video=efifb:off,vesafb:off but people always seem to find other drivers that latch onto vga it seems. I'd certainly want a serial console for that, I know from assigning IGD on my laptop what a pain it is to run completely headless. > Also, for the OVMF, I see two UEFI x86_64 modes available when I create a > virtual machine: > > UEFI x86_64: /usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd > UEFI x86_64 /usr/share/edk2/ovmf/OVMF_CODE.fd > > I don't understand why there's two or what the difference is between them. > All my tests have been using the first one (pure-efi).

The other is delivered by Fedora (older).
