Hi I downloaded a rom from the Internets. There is a common site that has a library of them. I have been meaning to try without the rom file too. Not sure it's necessary.
I think you have a tougher time because you have two AMD cards. I am able to blacklist the AMD driver completely because my "other card" is Intel. Are you using the uefi bios for your virtual machine? scott On Jan 23, 2017 9:37 AM, "P.
