I think this might work (I have not tried it):
use function (_FUNCTION_, not interrupt) call Eh. It will do two things:
make the drive selected in DL the current drive, and
return the number of drives in AL.

The way the drives are numbered is A=0, B=1, ....
BUT:   I believe if you have one physical drive (i.e. 0 being called A:),
then you will also have 1 (B:), and DOS will do the prompting for switching
of disks (i.e. Diskcopy a: b: with only one drive....)
