Soft-Off by PWRBTN

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. The
default value is
Instant Off .

Wake Up Events
The HDD, FDD, COM, LPT Ports, and PCI PIRQ 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 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.
