Yeah, and they exist, but should basically be considered broken.

EFi without BIOS emulation is such a crazy idiotic crock that it's not
even funny. It's pure and utter shite.

EFI as a "extended BIOS rewritten in C" is not bad.

EFI as a "new world order" is totally idiotic and crazy, and only
morons ever believed it was a good idea.

Sadly that "pure EFI" thing still exists. Some of the early EFI
proponents really wanted it, and it's still an option for some
unfathomable reason. The world would be a better place without it.
