MSI Reminds You...
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 I/O device.
