Key Features

Introduction
1-7
The MSI special features are designed and developed by MSI R&D,
which are only available in MSI mainboards. The MS-6391 mainboard
is OPTIONALLY equipped with the following features:
PC Alert™ III
The PC AlertTM III is a utility you can find in the CD-ROM disk.
The utility is just like your PC doctor that can detect the following PC
hardware status during real time operation:
*monitor CPU & system temperatures
*monitor fan speed(s)
*monitor system voltage
*monitor chassis intrusion
If one of the items above is abnormal, the program main screen will be
immediately shown on the screen, with the abnormal item highlighted
in red. This will continue to be shown, until user disables the warning.
MSI Special Features
Note: Items shown on PC Alert III vary depending on your system’s
status.

D-LED™
The D-LED™ uses graphic signal display to
help users understand their system. Four LEDs em-
bedded in the mainboard provide up to 16 combina-
tions 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 use-
ful 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.

The mainboard supports Intel®Pentium®4 processor in FC-PGA2
package. The mainboard uses a CPU socket called PGA478 for easy CPU
installation. When you are installing the CPU, make sure the CPU has
a heat sink and a cooling fan attached on the top to prevent overheating.
If you do not find the heat sink and cooling fan, contact your dealer to
purchase and install them before turning on the computer.
CPU Installation Procedures
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
2. Look for the dot/cut edge.
The dot/cut edge should
point towards the lever
pivot. The CPU will only
fit in the correct orientation.
3. Hold the CPU down firmly,
and then close the lever to
complete the installation.
