CHAPTER 1 INTRODUCTION

1-1

The MICRO ATX EX7 mainboard is a high-performance personal computer

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

combines leading edge AGP ATI®3D RAGE PRO technology in graphics

and YAMAHA®YMF740 PCI technology in audio. The Intel®Pentium®II

processor supports MMXTM(Multimedia Extension) technology.

The mainboard uses the highly integrated Intel®82440EX 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, and system temperature

monitor.

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 jumper switch

(JP1) 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/Bridgeassemblies

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)

*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.

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

HeatSink.

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.
