Doesn't make a bit of difference. In PNPBIOS or ACPI world you're free
to move things wherever.

Better to just make the BIOS call to turn off the floppy motor -- and
much more certain since the BIOS by definition will do it right and
know the proper location. We already use the BIOS for all I/O in the
boot blocks, so one more BIOS call makes more sense.
