My understanding is that in a machine with multiple VGA devices only one vga device is setup to forward the legacy VGA IO ranges over PCI, and only that device should have its option ROM executed.
My understanding is that running the vga option roms for all vga devices would be incorrect and could cause a real machine to not boot properly.
how's that different in pci vs vgaroms/ ? "Could cause a real machine to not boot" is true regardless.
I don't understand your question. For regular PCI devices every option rom should be run, regardles of how many devices are in the system. VGA option roms are special though - my understanding is exactly one VGA device should have its option rom executed.
