Chapter 3 IRQs Activities Press to enter the sub-menu and the following screen appears: Primary INTR Selecting ON will cause the system to wake up from power saving modes if activity is detected from any enabled IRQ channels. Settings: OFF and ON. IRQ3~IRQ15 Enables or disables the monitoring of the specified IRQ line. If set to Enabled, the activity of the specified IRQ line will prevent the system from entering power saving modes or awaken it from power saving modes. Settings: Disabled and Enabled. Note: IRQ (Interrupt Request) lines are system resources allocated to I/O devices. When an I/O device needs to gain attention of the operating system, it signals this by causing an IRQ to occur. After receiving the signal, when the operating system is ready, the system will interrupt itself and perform the service required by the IO device. 3-20
