MSI ATX BX7 Manual de usuario
CHAPTER 1 INTRODUCTION
1-1
The MICRO ATX BX7 mainboard is a high-performance personal computer
mainboard based on the Intel®Pentium®II processor. This mainboard
combinesleadingedgeAGPATI®3D RAGE PRO/RAGE PRO Turbo technol-
ogy in graphics and Creative®ES1371/ES1373(reserved) PCI technology in
audio. The Intel®Pentium®II processor supports MMXTM (Multimedia
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 as an
optional function. 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/Bridgeassemblies
inserted up through the bottom of the
motherboard. RM secures to RMAM ( 2
RMAM required per RM ).
*Heat SinkSupport Base(HSSBASE) - Plastic support bar mounted to
the mainboard under the ATX heatsink.
(One leg is always bigger than the other one)

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.
