INT 15H 82H: Program Termination

                                                                        [AT]

    Info: This service is designed to be intercepted by a multitasking
          operating system.  It would be used, along with INT 15H fns 80H
          and 81H, to avoid device conflicts.

          When unintercepted, the BIOS simply sets AH to 0 and clears CF.
