Int 70 - IRQ8 - Cmos Real-time Clock [H]
Desc: this interrupt is called when the real-time clock chip generates an
alarm or periodic interrupt, among others. The periodic interrupt
occurs 1024 times per second.
Nots: many BIOSes turn off the periodic interrupt in the INT 70h handler
unless in an event wait (see INT 15/AH=83h or INT 15/AH=86h).
may be masked by setting bit 0 on I/O port A1h
