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 operating 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.
