Can't boot OVMF. Could it be a vbios issue? EFI or Legacy bios on Gigabyte Geforce 670

Hello, 

 

I'm running Primary GPU passthrough using Seabios after extracting my vbios from the card, it's working but I believe my performance issues could be fixed by OVMF amongst other things.

 

I've seen some threads suggesting that I may need an updated vbios for my card. Any suggestions?

 

It's this card.

From the page I've linked :  UEFI Supported - No

That's a vbios with UEFI support, I'm guessing I need to install that which means I also need to extract that bios again from my card which will require another GPU again.

 

If anyone has run into this and can say or suggest I'm on the right path please let me know.

I downloaded the updated Bios direct from Gigabytes website, every attempt at using a Gigabyte application failed to flash the card or even really detect it.

 

Finally found nvflash ( https://www.techpowerup.com/download/nvidia-nvflash/ ) which allowed me to flash the bios from Gigabyte easily and OVMF worked afterwards.
