How do you know that the monitor receives something?
Well, when no receives nothing there is a no signal message on screen and disappears when the console is initialized by coreboot.
Please try it to know that the VGA Option ROM you are using is correct for example. It’s a valuable data point.
The VGA option rom is correct. Previously I was using tianocore payload and was able to initialize a EFI console.
No clue about the entry not enumerated in the pci_bus 0000:00 ?
Thanks!
