The O/S APM driver must poll the APM BIOS to determine an event code. The O/S driver uses its interface connection to
call function Get_power_managed_event (AH = 0x0B). The APM BIOS will acknowledge the call with an event code in reg-
ister BX. When multiple events occur, the APM BIOS will return all events in a time-ordered sequence. Table 567 is a quick
reference for event codes.
