It is for the stepper motor for 5.25" drives.  $C0E2 turns off stepper motor
one.

If the manuals don't say anything, it's not a documented entry
point and won't be supported in other ROM versions.  So don't call
it from any commercial software you write, but if you want to explore
that's a great idea (if you have the time).  Alas, I have no time to
hack anymore.
