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!
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, even if this one is on primary slot #1.
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.
