the ATX power supply is connected, there are many ways to power on the system.
Please read the following description for the details.
POWER BUTTON
The power button (PW switch) on the front panel is not only for power-on and
power-off the PC system. When the ATX type power supply is connected to the
mainboard, it can be programmed by COMS setup program and it has different
features. Please refer to Section 3-2 (page 3-12, 3~13) for the detail of function
description.
¨ KEYBOARD PASSWORD or HOT KEY (optional)
When ATX type power supply is used with this mainboard, you may enter your
personal password or a combination of hot key in the CMOS setup program so that
you can use the keyboard password or hot key to power on your system. When the
system power is off, This mainboard has the stand-by 5V voltage active and it will
keep scanning the keyboard status waiting for the correct password or hot key input
to turn on the system power. Without the correct password or hot key, no one else
can turn on the PC system ( neither by the power button ).
There are two ways to power-on the PC system by keyboard, they are “Password”
and “Hot KEY”:

external modem installed, you can use it to power on the PC system. When there is
the incoming message from the external modem, the PC system will be triggered by
the ring-in signal and wake up automatically to receive the message for you.
In order to use the ring-in signal to wake up your PC system, you will have to use
the EXTERNAL MODEM and have it connected to one of the Serial Ports (COM1
or COM2). When the system power is off, this mainboard will continue to detect the
serial port status. When it detects the ring-in signal from the serial port, the system
power will be turned on and start to receive the incoming messages automatically.
To enable the Modem Ring-In feature, you have to run the BIOS setup utility and
enable the “Modem or LAN resume” option (it is in the “POWER MANAGEMENT
SETUP”, please refer to Section 4.7 for the settings). Having completed the BIOS
setup, you have to reboot the PC system so that BIOS can verify the setting. (the
“DMI pool data” will be verified by the BIOS when loading the operating system).
Simply speaking, shut down the PC system and then re-start the system. The modem
ring-in feature will be enabled when the operation system has been loaded.
Note: This function is not available when using the internal MODEM card.
¨ WAKE ON LAN ( WOL ) ( For ATX power supply only)
There is a WOL connector CN14 (see Section 3-2) on the mainboard which is
designed to connect to the signal from a LAN card which supports the Wake On
LAN feature. When such LAN card is installed, you may turn on the PC system
from your remote server and monitor the PC status.
To enable this feature, you will have to use the BIOS setup utility to enable the
“Modem or LAN resume” (it is located at “POWER MANAGEMENT SETUP”,
