Next is that such "hardware support" exist in every modern PC today: such
pin is used by Linux and even MS DOS already (to discard cache contents
only when floppy was changed). But you need to poll it from time to time
since you can ask drive a question "was floppy changed" but you can not get
an interrupt when floppy is changed. So if we'll call THAT "hardware support"
then either it's not "like Mac" or it's not "something which the PC's don't
have" (I'm not know Mac internals good enough to say exactly).
