On some devices, I see the line "EFI stub: load initrd from command line option" (or similar) as just another line on the same text screen that prints early UEFI messages.
And I'm still wondering about that and how text-mode/console output works.
I get it when I'm attached via a serial port, but... how many console rendering implementations for VGA output are on my system?
