Intel wanted to rip OpenFirmware off and wanted to EEE it without paying lip service to Sun et al.

It isn't an accident that both, for example, use Forth.

That's why I've asked? Where is the FORTH in EFI, or any UEFI, for that matter?

[DiabloD3]

Look up "UEFI shell" for your vendor. Sometimes this is an unlisted F key, sometimes its as simple as selecting it as which OS you want to boot, sometimes it will happen automatically if no boot device is discovered, sometimes you must supply it as a bootx64.efi from the vendor (or from Tianocore).

Just because UEFI is a standard doesn't mean all the vendors don't smoke crack.
