Notes
DR DOS 3.41-5.0 DRIVER.SYS does not support drive mapping and thus
always returns AL=00h; Windows NT 4.0 also always returns AL=00h in addition to the normal operation, if Stacker is installed, this call also sets the volume number at offset 58h in the Stacker device driver (DR DOS 3.41-5.0 only; use AX=4408h otherwise) (see AX=4404h"Stacker",INT 25/AX=CDCDh)
