It's been ages since I've messed with floppies, but I seem to recall that
traditionally the floppy drive hardware was incapable of alerting the OS

As far as I was aware, pin 34 was a diskchange indicator. And there's
various ways for the drive to sense media is in the drive (optical
sensors, pin sensors, at least).
Yes, but no interrupt is generated on medium change.
Supposedly both floppies and CD/DVD drives have a method of telling the
host about media changes, but it seems like people don't bother to take
advantage of them (doing silly things like periodically trying to spin
the disc to see if one's being inserted, instead).
At one time Solaris did that, if you configured it to.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
