INTRODUCTION
The 694 Master (MS-6309 ver 3.0) A TX mainboard is a high-performance
computer mainboard based on VIA® VT82C694X chipset. The 694 Master
(MS-6309 ver 3.0) is designed for the Intel® Celeron
TM
or Coppermine (FC-
PGA) processor for inexpensive business/personal desktop markets.
The Apollo Pro133A (VT82C694X) is a Socket-370 system logic north bridge
with the addition of 133 MHz capability for both the CPU and SDRAM
interfaces. Apollo Pro133A may be used to implement both desktop and
notebook personal computer systems from 66MHz to 133MHz based on
Socket-370. The primary features of the Apollo Pro133A-North Bridge are:
Slot-1 or Socket-370 CPU (Front Side Bus) Interface (66 / 100 / 133MHz),
DRAM Memory Interface (66 / 100 / 133MHz), AGP Bus Interface (66MHz),
PCI Bus Interface (33MHz), Mobile Power Management.
The VT82C686B PSIPC (PCI Super-I/O Integrated Peripheral Controller) is a
high integration, high performance, power-efficient, and high compatibility
device that supports Intel and non-Intel based processor to PCI bus bridge
functionality to make a complete Microsoft PC99-compliant PCI/ISA system.

HARDWARE INSTALLATION
Central Processing Unit: CPU
The mainboard operates with Intel® CeleronTM/Pentium® III (FC-PGA)
processor. The mainboard uses a CPU socket called Socket 370 for easy
CPU installation. The CPU should always have a Heat Sink and a cooling
fan attached to prevent overheating.
3. Press the lever down to
complete the installation.
2 . Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.

The BIOS can be used to set the CPU Host Bus Frequency Clock.
If CPU Clock = 66MHz
Core/Bus ratio = 3.5
then CPU core speed = Host Clock x Core/Bus ratio
= 66MHz x 3.5
= 233MHz

• Fan Power Connectors: CPUFAN & SYSFAN
These connectors support system cooling fan with + 12V. It supports
three pin head connector. When connecting the wire to the connector, always take note that the red wire is the positive and should be
connected to the +12V, the black wire is Ground and should be
connected to GND. If your mainboard has System Hardware Monitor
chipset on-board, you must use a specially designed fan with speed
sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System Hardware Monitor will count and report the fan rotation
speed.
Note: Always consult your reseller for proper CPU cooling fan.

A. How to install a DIMM Module
1. The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the
DIMM memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM slot.
Then push it in.
3. The plastic clip at the side of the DIMM slot will automatically
close.
