Indeed, when I was trying to track down a bug in floppy booting
(with mixed drive types), I wasted some time thinking I had found
the bug in one such instance, having temporarily forgotten about

exactly what is meant, instead of invoking some behind-the-scene
mapping. But I think it was an interesting experiment anyway.
