I would imagine that the UEFI framebuffer works even before the OS loads. It would be interesting to learn how this happens and what state the cards are in.

UEFI implementations are not called "Operating Systems" because they lack things like interrupts and a scheduler but they can do 10 times more than what MSDOS (MS Disk _Operating System_) ever did.

Because MS-Dos never claimed to be an _Operating System_. It operated the disk. That was all it claimed, it didn't claim to operate the computer ...

Cheers,

Precisely - DOS sits at the same layer GRUB does, it's the liminal space between the MBR and what you turned your computer on for, not a useful application unto itself.

(Suddenly the EFI Shell being designed the way it is makes a lot more sense to me…)
