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.
Wake up by PCI Card
By default, this field is disabled.
Power On by Ring
This field enables or disables the power on of the system through the
modem connected to the serial port or LAN.
Resume by Alarm
This field enables or disables the resumption of the system operation.
When enabled, the user is allowed to set the Date and Time.
Reload Global Timer 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.
