The following is a list of IRQ’s, Interrupt ReQuests, which can
be exempted much as the COM ports and LPT ports above can.
When an I/O device wants to gain the attention of the operating
system, it signals this by causing an IRQ to occur. When the operat-
ing system is ready to respond to the request, it interrupts itself and
performs the service.
When set On, activity will neither prevent the system from going
into a power management mode nor awaken it.
