Managing The PC BIOS

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.

Note: When set On, activity will neither prevent the system from going into a power management mode nor awaken it.
