MSI MICRO ATX BX11 Manual de usuario

CHAPTER 1 INTRODUCTION

1-1

The MICRO ATX BX11 mainboard is a high-performance personal computer

mainboard based on the Intel®Pentium®II processor. This mainboard

features the leading edge Creative®ES1371/ES1373(reserved)PCItechnol-

ogy in audio. The Intel®Pentium®II processor supports MMXTM (Multime-

dia Extension) technology.

The mainboard uses the highly integrated Intel®82443BX AGP chipset to

support the PCI/ISA and Green standards, and to provide the Host/AGP

bridge. The Intel®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

of33MB/s.

The mainboard also supports the System Hardware Monitor Controller. Its

functions include: 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/CeleronTM processor. The

mainboard uses a CPU Slot called Slot 1 for easy CPU installation and a

jumper 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

Different kinds of Pentium®II processor that is currently used: the OEM

version, the Boxed version, and CeleronTM. OEM Pentium®II Processor has

no Heat Sink, Fan and Heat Sink Support, the Boxed Pentium®II Processor

is provided with Heat Sink w/ fan and Heat Sink Support, while the

CeleronTM processor is a plain processor card without cover or heatsink..

Required Things:

Pentium®IIprocessor- Processor.

*RetentionMechanism(RM)- Plastic Guide that holds the S.E.C. Catridge

in the Slot 1 connector.

*RetentionMechanismAttachMount(RMAM)-Bolt/Bridge assemblies

inserted up through the bottom of the

motherboard. RM secures to RMAM ( 2

RMAM required per RM ).

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

the mainboard under the ATX heatsink.

(One leg is always bigger than the other one)

required per Assembly).

*Heat Sink Support Top 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

processorwith metal clip.

Step 1: Insert the Retention Mechanism Attach Mount at the bottom

of the mainboard.

Step 2: Install the Retention Mechanism.

Look for the key on Slot 1, and match it with the Notch Key on the

Retention Mechanism for proper direction. Then, attach the

Retention Mechanism to the Retention Mechanism Attach Mount.

Use a Screwdriver to secure the Retention Mechanism.

Step 3: Install the Heat Sink Support Base.

Look for the Two holes across Slot 1, and match it with the Two legs

of the Heat Sink Support Base for the proper direction. Take 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.
