Video Off Method
This field defines the Video Off features. There are three options.
V/H SYNC + Blank Default setting, blank the screen and turn
off vertical and horizontal scanning.
DPMS Allows the BIOS to control the video
display card if it supports the DPMS
feature.
Blank Screen This option only writes blanks to the video
buffer.
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. 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.
