December 26, 20187 yr Hi, got a PC with 3 GPUs: NVIDIA RTX 2080, NVIDIA GTX780Ti and AMD RX550. After hours of research, I’m still trying to find a way to prioritize the RX550 as the default GPU at boot time! I want to use KVM/QEMU to leverage GPU passthrough for 2 VMs, each with a dedicated NVIDIA graphics card. The motherboard is Asus Crosshair Hero VII Wifi, with the latest BIOS. The processor is a Ryzen 2700X. Can’t find any GPU boot order option or menu in the BIOS, which is just crazy!! I owned a X59 motherboard which made things so damn easy. It is now 2018 and I thought it would be such a trivial thing to do, but it’s NOT. I’ve tried to reorder GPUs on different PCIe slots without success. Also, NVIDIA GPUs are always getting priority over AMD. How can I force the motherboard to POST/initialize on a specific GPU e.g. AMD?! Is this 'problem" specific to modern motherboards using UEFI?! Thanks. Edited December 26, 20187 yr by CONTINUUM
