INTRODUCTION

The MS-6309 A TX VA5 mainboard is a high-performance computer
mainboard based on VIA® VT82C694X chipset. The MS-6309 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 (Intel Celeron processors). 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 VT82C686A 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

2.1 Central Processing Unit: CPU

The mainboard operates with Intel® CeleronTM/Coppermine 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.

2.1-1 CPU Installation Procedures

CHAPTER 2 HARDWARE INSTALLATION

2-2

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

2.1-3 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: 1. Always consult vendor for proper CPU cooling fan.

2. CPU F AN supports the FAN control. You can install PC Alert

utility . This will automatically control the CPU F AN Speed according
to the actual CPU temperature.
