MSI MS-6117 User manual

CHAPTER 1 INTRODUCTION
1-1
The MS-6117 is a high-performance personal computer mainboard based on
the Pentium®II processor.
The mainboard uses the highly integrated Intel®82440LX AGPset which
optimize the system bandwidth and concurrency with the implementation of
Quad Port Acceleration (QPA). QPA provides 4-port concurrent arbitration
of the processor bus, graphics, PCI bus and SDRAM.
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 Intel®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
(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
2-2
A. OEM Pentium®II Processor Installation Procedures
There are two kinds of Pentium®II processor that is currently used: the
OEM version and the Boxed version. 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 holdsthe 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 ).
*HeatSinkSupportBase(HSSBASE) - Plastic support bar mounted to
the mainboard under the ATX heatsink.
