When the mainboard has been installed successfully, there are several ways to
power on the system. Please read the following description for all the details.
¨POWER BUTTON
The power button can be programmed by COMS setup program and it has different
features. Please refer to page 3-11 for detail function description.
¨KEYBOARD (PASSWORD OR HOT KEY)
This mainboard allows you to use your personal password or a combination of hot
key to power on your PC system. (Before you can use this feature, the jumper
setting on JP1 must be “Enabled”). When you have used the BIOS setup program
and selected the Password to power on the PC system, the keyboard OnNow
function will be activated and this mainboard will keeps scanning the keyboard
status waiting for the correct password or hot key input even when the system power
is “OFF”. Under this circumstance, the only way to power on the PC system will be
the correct password or a combination of “hot key”. ( you can not use the power
button on the front panel to power on the PC system.). Please refer to the “Power On
Function” setup in Section 4.9.- " Integrated Peripherals " for setup details.
In case that you forget the “Password” or “Hot Key”, disconnect the AC power for
30-60 seconds then re-connect the AC power to the PC system, the power button will
be activated again and you can use the power button to turn on the system. Input
your personal password again in the BIOS setup program, and then you may use the
new password to power-on the PC system afterward.
¨PS/2™ MOUSE (LEFT OR RIGHT MOUSE BUTTON)
If you have a PS/2™ mouse connected to the system, you may change the setup in
the BIOS and use the mouse click to turn on the PC system power. Please refer to
section 4.9.- " Power On Function " for the BIOS setting
To use the mouse key to turn on the PC system power, the mouse click must be done
quickly and continually. Basically, 2-5 quick clicks on the mouse key ( left key or
right key ) will turn the power immediately.
Note: 1. This feature is not available on the COM port mouse (serial mouse).
2. To use the PS/2 mouse power-on the PC system, JP1 must me "Enabled"

VIA 693A ATX MAINBOARD INSTALLATION
2-3
¨RTC ALARM
PC system can be waked up by the RTC setting in the CMOS. You can set the
alarming date and time in the BIOS setup program, When RTC alarms, the PC
system will be triggered and wakes up automatically.
Enable the “RTC Alarm Resume” selection in the BIOS setup utility, and then you
will see the input request for the date and time. (you can find the “RTC Alarm
Resume” in the “POWER MANAGEMENT SETUP” in Section 4.7), When you
have stored the RTC alarm setting, the PC system will be turned on automatically
according to the date and time which is recorded in the CMOS memory.
¨MODEM RING-IN
This mainboard supports the Modem Ring-In power on feature. 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 )
on the mainboard. When the mainboard detects the ring-in signal from the serial
port, the system power will be turned on instantly
To enable the Modem Ring-In feature, you have to run the BIOS setup utility and
enable the “Modem or LAN Resume” option (refer to Section 4-7 - “POWER
MANAGEMENT SETUP”).
¨WAKE ON LAN ( WOL )
There is a WOL connector CN16 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 the 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” in the BIOS setup program.
Note: This function will be disabled if you turn off the power before the system can
verify the DMI pool data.
2.3 POWER OFF THE PC SYSTEM
There are two ways to power off the system. They are “Shut Down by Power Button”
and “ Shut Down by OS”. (such as Windows® 95 and Windows® 98, you can choose
