The <acronym>BIOS</acronym> has a predefined set of services, requested by applications as software-generated interrupts through the <literal>int</literal> instruction and receiving arguments in registers (in this case, <literal>%ah</literal>). Here, particularly, we are requesting the number of clock ticks since last midnight; this value is computed by the <acronym>BIOS</acronym> through the <acronym>RTC</acronym> (Real Time Clock).
