INT 1Ah,  07h (7)        Reset Real-Time Clock Alarm                     many

Prevents the real-time clock alarm from occurring.

On entry:      AH         07h

Returns:       None

                                                                          

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).
