The point was that the boot menu function and the no emulation vs. hard
disk emulation vs. floppy emulation are orthogonal.
It appears that really old BIOSes work like crap for anything but floppy
emulation; some contemporary BIOSes like crap for anything but no
emulation. This seems to follow what the current Micro$oft OSes use,
i.e. again -- the BIOS vendors test "does it boot M$, ok then."
