MSI MS-6117 User Manual

CHAPTER 1 INTRODUCTION

1-1

The MS-6117 is a high-performance personal computer mainboard based on
the Pentium® II processor .

The mainboard uses the highly integrated Intel® 82440LX AGPset which
optimize the system bandwidth and concurrency with the implementation of
Quad Port Acceleration (QPA). QPA provides 4-port concurrent arbitration
of the processor bus, graphics, PCI bus and SDRAM.

The Intel® 82371AB chipset integrates all system control functions such as
ACPI (Advanced Configuration and Power Interface). The ACPI provides
more Energy Saving Features for the OSPM(OS Direct Power Management)
function. The Intel® 82371AB chipset also improves the IDE transfer rate by
supporting Ultra DMA/33 IDE that transfers data at the rate of 33MB/s.

The mainboard also supports the LM78 System Hardware Monitor
Controller as optional function. The LM78 function includes: CPU /power
supply/chassis fan revolution detect, CPU/system voltage monitor, system
temperature monitor , and chassis intrusion detect(optional).

HARDWARE INSTALLATION

2.1 Central Processing Unit: CPU

The mainboard operates with Intel® Pentium® II processor . The mainboard
uses a CPU Slot called Slot 1 for easy CPU installation and a DIP switch
(SW1) to set the proper speed for the CPU. The CPU should always have a
Heat Sink and a cooling fan attached to prevent overheating.

2.1-1 CPU Installation Procedures

2-2

A. OEM Pentium® II Processor Installation Procedures

There are two kinds of Pentium® II processor that is currently used: the
OEM version and the Boxed version. OEM Pentium® II Processor has no
Heat Sink, Fan and Heat Sink Support, while the Boxed Pentium® II
Processor is provided with Heat Sink w/ fan and Heat Sink Support.

Required Things:

Pentium® II processor - Processor .
*Retention Mechanism(RM) - Plastic Guide that holds the S.E.C. Catridge

in the Slot 1 connector .

*Retention Mechanism Attach Mount(RMAM) - Bolt/Bridge assemblies

inserted up through the bottom of the
motherboard. RM secures to RMAM ( 2
RMAM required per RM ).

*Heat Sink Support Base (HSSBASE) - Plastic support bar mounted to

the mainboard under the ATX heatsink.
(One leg is always bigger than the other one)

of the Heat Sink Support Base for the proper direction. T ake note
that one hole/leg is bigger than the other. The Four top pins of the
Heat Sink Support Base should also be oriented towards Slot 1.

Push the Heat Sink Support Base onto the mainboard, until you hear
a click sound. Check for a perfect fit.

Step 4: Install the Heat Sink Support Pin.

Push the Heat Sink Support Pins onto the two holes of the Heat Sink

Step 5: Install the Heat Sink with Fan to the Processor .

Push down the metal clips, so that they are in line with the back of
the Heat Sink. Be careful, so as not detach the metal clips from the
Heat Sink.

In case the metal clips are detached from the Heat Sink, re-attach
them. Look for the arrow on the metal clip. This arrow should be
pointing down and aligned with the Heat Sink Support Base Holder.

Attach the Heat Sink to the processor.

- Look at the back of the Heat Sink and take note of the 2 secure
posts. Insert these 2 Secure posts to the 2 secure holes on the
back of the processor.

- Align the ears of the metal clips with the clip holders on the back of
the processor. Use a screw driver to push the metal clips onto the
clip holders. Check for a perfect fit.

2.1-2 CPU Speed Setting: SW1

To adjust the speed of the CPU, you must know the specification of your
CPU (always ask the vendor for CPU specification). Then look at Table 2.1

(200 ~ 333MHz Pentium® II processor ) for proper setting.

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 LM78 chipset on-board, you must use a specially designed
fan with speed sensor to take advantage of LM78’ s CPU fan control.

The mainboard supports a maximum of 1 GB of memory for EDO and 512MB
for SDRAM: It provides three 168-pin unbuffered DIMMs (Double In-Line
Memory Module) sockets. It supports 8 MB to 256 Mbytes DIMM memory
module. The memory module can be either SDRAM or EDO (Extended Data
Output) Mode DRAM. A DIMM consists of two Banks and may have a
maximum of 256 MB of memory .

DIMM1(Bank0 + Bank1)

DIMM2(Bank2 + Bank3)

DIMM3(Bank4 + Bank5)

A. How to install a DIMM Module

1. The DIMM slot has a two Notch Key “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. Close the plastic clip at the side of the DIMM slot.

Single Sided DIMM

Double Sided DIMM

Note: Y ou can only use a 3.3 volt DIMM module (EDO or SDRAM).
