Introduction 1
The MS-6394 V1.X Micro ATX mainboard is a high-performance compu-
ter mainboard based on ServerWorks®LC-T North Bridge & ServerWorks®
CSB5 South Bridge chipsets. The MS-6394 is designed for Intel®Pentium®III
(FC-PGA) processor for cost-effective business/personal desktop and entry-
level server markets.
The ServerWorks®LC-T chipset provides an integrated high-perform-
ance main memory sub-system, a dual channel PCI bus bridge that provides an
excellent data flow path between the processor bus and a 64-bit PCI bus/the
processor and a 32-bit PCI bus. The DRAM interface provides support for 64-
Mbit, 128 and 256Mbit technology, which will allow up to 128/256/512 Mbytes
per two rows (Double Sided DIMM) and a maximum memory size of 2GB. It also
implements I2C interface, which can be used to access the internal registers.
The ServerWorks®CSB5 chipset primarily works as a PCI to Low Pin
Count (LPC) Bridge and is also a source of numerous other integrated functions.
Its main features are: PCI-LPC address/data bridge, DMA controller, IDE (up to
ATA100) & IDE RAID interfaces, ACPI, USB controller, SMBus host and slave
interface,...and etc.

The D-LED™ uses graphic signal display to help users understand
their system. Four LEDs embedded in the mainboard provide up to 16 combi-
nations of signals to debug the system. The 4 LEDs can debug all problems
that fail the system, such as VGA, RAM or other failures. This special feature
is very useful for the overclocking users. These users can use the feature to
detect if there are any problems or failures.

Hardware Setup
This chapter provides you with the information about hardware setup
procedures. While doing the installation, be careful in holding the components
and follow the installation procedures. For some components, if you install in
the wrong orientation, the components will not work properly.
Use a grounded wrist strap before handling computer components. Static
electricity may damage the components.

CPU Installation Procedures
The mainboard operates with Intel®Pentium®III, Intel®CoppermineTM /
TualatinTM processors. The mainboard uses a CPU socket called Socket 370
for easy CPU installation. The CPU should always have a Heat Sink and a
cooling fan attached to prevent overheating.
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the gold arrow.
The gold arrow should point
towards the end of lever.
The CPU will only fit in the
correct orientation.
3. Hold the CPU down firmly,
and then close the lever to
complete the installation.

Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.

CPU Core Speed Derivation Procedure
If CPUClock = 100MHz
Core/Bus ratio = 8.5
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 8.5
= 850MHz
While replacing the CPU, always turn off the ATX
power supply or unplug the power cable of the ATX
power supply from grounded outlet first to ensure the
safety of CPU.
WARNING!
