This is off the top of my head, so be warned: I remember doing 
something similar in the past (a sector editor/recronstruction/backup
utility) and I'm sure that when using int13/func2 you specify DL=2 to
read C:, unlike disk reset (int13/func0). ???

My main reaon for posting: this reminded my of a long standing question
I've had. Is there any way of telling exactly which drive was the boot device?
(other than assuming it from the COMSPEC variable or other inductive means)
This must be documented somewhere, but God knows I've tried finding the answer
without success.
