    control can be returned to the instruction following this power-off
    call. (PC Convertible only.)

    Control is returned immediately if this service is not available. If
    it is available, then power is turned off. The next time the system is
    turned on, if the event type code (AL) is 1 or the System Profile (see
    Service 40h) has warm start mode set, the machine will start right
    where it left off, executing the program that generated this service.

       Notes:         This service is available only for the PC
                      Convertible.

                      Before the system is powered down, the diskette
                      motors are turned off.
