    Info: This service is designed to be intercepted by a multitasking

          operating system.  It could be used by disk or other hardware

          handlers so the handler can be notified when I/O is completed.

          This fn could also be used by an operating system to learn when

          I/O is completed so the requesting task could be reactivated.

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