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 oper-
ating system, it signals this by causing an IRQ to occur. After re-
ceiving the signal, when the operating system is ready, the system
will interrupt itself and perform the service required by the I/O
device.
