PM Timers and IRQ Wakeup Events
The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that 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 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.
Modem Use IRQ
This field sets the IRQ used by the Modem. By default, the setting is 3.
Soft-Off by PWRBTN
This field defines the power-off mode when using an ATX power supply.
The Instant Off mode allows powering off immediately upon pressing the
power button. In the Delay 4 Sec mode, the system powers off when the
power button is pressed for more than four seconds or enters the suspend
mode when pressed for less than 4 seconds.
