CHAPTER 1 INTRODUCTION
1-1
The MS-6111 is a high-performance personal computer mainboard based on
the Pentium®II processor.
The mainboard uses the highly integrated Intel®82440LX chipset to support
the PCI/ISA and Green standards, and to provide the Host/AGP bridge. 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 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 withIntel®Pentium®II processor. The mainboard
uses a CPU Slot called Slot 1 for easy CPU installation and a DIP switch
(JBF1) to set the proper speed for the CPU. The CPU should always have a
Heat Sink and a cooling fan attached to prevent overheating.

CHAPTER 2 HARDWARE INSTALLATION
2.1-1 CPU Installation Procedures
2-2
A. OEM Pentium®II processor Installation Procedures
There are two kinds of Pentium®II processors 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®IIprocessor - Processor.
*RetentionMechanism(RM) - Plastic Guidethat holds the S.E.C. Catridge
in the Slot 1 connector.
*HeatSink Support Base(HSSBASE) - Plastic support bar mounted to
the mainboard under the ATX heatsink.
(One leg is always bigger than the other one)
*HeatSink Support Pin (HSSPIN)- Plastic pins inserted through the
HSSBASE to secure it to the mainboard (2
required per Assembly).

Step 1: Place the bubble bag that came with your mainboard or use
any soft material like Styrofoam underneath the mainboard. Find a
flat surface to do the installation.
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 the proper direction. Then, insert the Two
Keylock of the Retention Mechanism into the two holes on the sides
of Slot 1. Take note that one hole is wider than the other. The
Retention Mechanism will only fit in one direction.
Push the Retention Mechanism onto the mainboard, until you hear a
“click” sound. Check for a perfect fit.

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.

B. Boxed Pentium®II processor Installation Procedures
The Boxed Pentium®II processor has a built- in Fan and Heat Sink. It also
has a Heat Sink Support. So if you’re going to use a Boxed processor, all
you need is the Retention Mechanism.
