For the past couple of days (when I’m procrastinating), I’ve been attempting to make an XFX RX 460 to to work as a GPU Passthrough on a macOS KVM.
Ready-made macOS VM
Flashing a different bios
# Display all adaptors detected ./amdvbflash -ai # Get info about the rom file ./amdvbflash -biosfileinfo vbios.rom # Save bios ./amdvbflash -s 0 original_rom # Force flash a rom ./amdvbflash -f -p 0 ./original_rom
Where to get bios rom files
How to know which BIOS are compatible
Run GPU-Z. Take note of the memory type and size.
Setting Proxmox to use a rom file
Where are the rom files located
How to use the romfile
I think I’ve tried almost all BIOS compatible with my graphics card. I was not able to make it work.
Too much time has been spent. I could have bought a fully compatible one for if I worked for the same amount of time I spent on this.
It was a good try, but I need to cut my losses (of time).
