INTRODUCTION

The ATX BX2 mainboard is a high-performance dual-processor personal computer mainboard based on the Intel® Pentium® II processor. The Intel

Pentium® II processor supports MMXTM(Multimedia Extension) technology .

The mainboard uses the highly integrated Intel® 82440BX chipset to support the PCI/ISA and Green standards, and to provide the Host/AGP bridge. The 82371EB 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® 82371EB 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 System Hardware Monitor Controller as an optional function. This 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 with MMX

technology . 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

A. OEM Pentium

II processor Installation Procedures

There are two kinds of Pentium® II processor that is currently used: the OEM Pentium® II processor and the Boxed Pentium® II processor. 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)

*Heat Sink Support Pin (HSSPIN) - Plastic pins inserted through the

HSSBASE to secure it to the mainboard (2 required per Assembly).

*Heat Sink Support T op Bar (HSSTOP) - Plastic bar that clips onto the

HSSBASE through the fins on the ATX heatsink.

**Heat Sink w/ fan - Heat Sink that can be attached to the Pentium® II

processor with metal clip.

Note: * Provided by MSI mainboard.

** Provided by Special request.

Step 3: Install the Heat Sink Support Base.

Look for the T wo holes across Slot 1, and match it with the Two legs 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 Support Base. Check for a perfect fit. These pins are used to secure the Heat Sink Support Base.

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.
