SOMETHING IMPORTANT !
¶TRADEMARKS
All trademarks used in this manual are the property of their respective owners.
¶LOAD SETUP DEFAULTS
“LOAD SETUP DEFAULTS” is the function which will have the BIOS default
settings loaded into the CMOS memory, these default settings are the best-case
values which will optimize system performance and increase system stability This
function will be necessitated when you receive this mainboard, or when the system
CMOS data is corrupted. Please refer to the Section 4.12 for the procedures.
¶DISCHARAGE CMOS DATA
Whenever you want to discharge the CMOS data or open the system chassis, Make
sure to disconnect the AC power first because there is always the 5V standby voltage
connected to the ATX form-factor mainboard. Without disconnecting the AC power
connector from the PC system, the mainboard can be damaged by any improper
action .
¶WAKE ON LAN
In order to support the Wake On LAN feature, the system requires a special SPS
(Switching Power Supply), Such power supply must be able to provide at least 700
mA of driving capability on the “5V standby” voltage. Please refer to the Section 3.3
for pin assignment.
¶WARNING !
The "Static Electricity" may cause damage to the components on the mainboard, In
order to avoid the damage to the mainboard accidentally, please discharge all static
electricity from your body before touching this mainboard.
¶NOTICE
Information presented in this manual has been carefully checked for reliability;
however, no responsibility is assumed for inaccuracies. The information contained in

1. INTRODUCTION
1.1 OVERVIEW
This Mainboard is a revolutionary high performance personal computer
mainboard. It is the ATX form-factor with the Socket 370 CPU connector
designed on the board for the Pentium™ !!! and Celeron™ processors. VIA
VT82C694X and VT82C686A chipsets are chosen as the system core logic of the
mainboard to give the most outstanding performance and reliability. VIA
VT82C694X is the energy efficient chipset and it supports the system front side
bus speed from 66MHz, 100MHZ to 133MHz for various Celeron™ and
Pentium™ !!! processors
VIA VT82C686A is a high integration, high integration, power-efficient and high
compatibility device which supports Intel and non-Intel processors to PCI bridge
functionality to make a complete PC99-compliant PCI/ISA system.. Beside the
ISA extension bus functionality, the VT82C686A provides two channels of "PIO”
and "Ultra DMA33/66 Bus Master” mode PCI IDE ports to support the most
updated Ultra DMA 66 HDD. There are one Floppy Disk controller, two high
speed Serial ports (UARTs), one multi-mode Parallel port, one PS/2™ mouse
port, one IR interface and four USB ports designed on the board for wide variety
of peripheral connection.
There is the full featured AGP (Accelerated Graphics Port) slot designed on the
mainboard which supports the 4X AGP mode. When you have the 4X AGP
display card installed on the mainboard, it will enhance the system display
performance tremendously. There is also the 3D audio interface integrated on the
mainboard (694TX has the audio interface designed on the board, but 694TXL
does not support audio interface and AMP slot.). When the audio interface is
installed on the mainboard, you need not invest any on the audio interface card.
Simply have the speaker connected to the audio connector (CN18) on the
mainboard and you will have the 3D sound effect in your PC system.
Note Pentium™ !!! and Celeron™ are the 32-bit processors with RISC technology,
which offers several key features such as built-in 512K/256/128K L2 cache, 12-
stage super-pipeline architecture, out of order execution … etc. In order to
optimize of its capabilities and performances, the 32-bit Operating System (such
as Windows® and OS/2™) and 32-bit applications are recommended.

2. INSTALLATION
2.1 UNPACKING
The mainboard contains the following components. Please inspect the following
contents and confirm that everything is there in the package. If anything is missing or
damaged, call your supplier for instructions before proceeding.
lThis mainboard.
lOne USER‘S MANUAL.
lOne Cable set for IDE and Floppy devices.
lOne CD diskette for device driver and utility programs plus the Virtual Drive.
This mainboard contains electrostatic sensitive components and it can be easily
damaged by static electricity. So please leave it sealed in the original packing until
when installing.
A grounded anti-static mat is recommended when unpacking and installation. Please
also attached an anti static wristband to your wrist and have it grounded to the same
point as the anti-static mat.
After the opening of the mainboard carton, please observe the mainboard carefully to
make sure there is no shipping and handling damage before you can start to install the
PC system.
Having finished all the procedures above, you are now ready to install the mainboard to
the chassis. Please make sure that the chassis is the ATX type so that the mounting hole
will match with this mainboard.

2.2 AMAZING WAYS TO POWER ON THE PC SYSTEM
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 3-12 for detail function description.
¨RTC ALARM
PC system can be started up by the RTC setting in the CMOS. You can set the
alarming date and time in the RTC memory, When RTC alarms, the PC system will
be triggered and waked up automatically on the date and time which you selected in
the BIOS setup program.
Enable the "RTC Alarm Resume” selection in the BIOS setup utility, and then you
will see the input request for the date and time. (the " RTC Alarm Resume” is
located in the "POWER MANAGEMENT SETUP”, please refer to Section 4.8),
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
The PC system can be used as a fax machine to send or receive fax messages. But
most people still use fax machine to receive their messages because it is not
practical to have the system powered on all day long waiting for the incoming
messages. Now the problem can be solved because this mainboard can be triggered
by a modem ring-in signal.
When you have a external modem installed, you can leave the PC system power
off. Whenever there is the incoming message, the PC system will be triggered by
the ring-in signal and wake up automatically to receive the message for you. From
now on, you can tell your PC system to receive the fax 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

VIA 82C694 ATX Mainboard INSTALLATION
2-3
( 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 and start to receive
the incoming messages automatically. ( you need to have the software like Award
Zero-Volt Data-Suspend Utility so that you can use the fax utility to receive the
incoming fax message ).
To enable the Modem Ring-In feature, you have to run the BIOS setup utility and
enable the "Modem / LAN Resume” option (it is located in the "POWER
MANAGEMENT SETUP”, please refer to Section 4.8 for the settings).
Note: This function is not available when using the internal MODEM card.
¨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 "Resume by Ring or LAN” in the BIOS setup program.
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
the Shut Down from the file menu and the system will be powered off immediately ).
