       Notes:         This service disables the alarm process. It does so
                      by not executing an INT 4Ah at any time. See Service
                      06h (Set Real-Time Clock Alarm) to set the alarm.
 
                      The real-time clock is the clock that runs even when
                      the computer is turned off. A CMOS battery is used
                      so that, even while the computer is off, the date,
                      time, and alarm time are maintained.
 
                      This service is available only for ATs, XT-286s, and
                      PC Convertibles. Previous machines will report
                      unpredictable results (including the state of the
                      Carry Flag).
