3.5.7.9 IRQ Wakeup Events

The VGA, LPT & COM, HDD & FDD, and PCI master are I/O events which can prevent the

system from entering a power saving mode or can awaken the system from such a mode.

When an I/O device wants to gain the attention of the operating system, it makes a signal

by causing an IRQ to occur. When the operating system is ready to respond to the request,

it interrupts itself and performs the service.
