BIOS SETUP
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.
AC Loss Auto Restart
This field sets the auto restarting function of the system when there is
AC power loss.
IRQ/Event Activity Detect
The items under this field 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.
