I remember a thing called menuetos, written mostly in assembly and fitting a single floppy drive while still having a decent ui and some drivers. You could probably fit that in a normal bios chip and/or boot it as a efi payload.
Imo it’s mostly about nobody having tried that yet (at least afaik).
I’ve been waiting for someone to do something more interesting with EFI. It’s extremely capable and could easily host a minimal recovery environment that would be invaluable in many situations, particularly on laptops which might be out in the field away from recovery tools when things break.
