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 de-
tect 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.
Note: Items shown on PC Alert III vary depending on your system’s
status.

Live BIOS™/Live Driver™
The Live BIOSTM is a tool used to detect and update your
BIOS online so that you don’t need to search for the correct
BIOS version through the whole web site. To use the function,
you need to install the “MSI Live Update Series” application.
After installation, the “MSI Live Update Series” icon (as the
right view) will appear on the screen.
Double click the “MSI Live Update Series” icon, and the following screen
will appear.
Four buttons are placed on the left column of the screen. Click the desired
button to start the update process.

D-Bracket™
D-Bracket™ is an USB bracket integrating four Diagnostic LEDs, which
use graphic signal display to help users understand their system. The LEDs
provide up to 16 combinations 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.

Chapter 2. 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.

Central Processing Unit: CPU
The mainboard supports Intel®Pentium®4 processor in the 478 pin
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
sinkandacoolingfanattachedonthetoptopreventoverheating. Ifyoudonot
find the heat sink and cooling fan, contact your dealer to purchase and install
them before turning on the computer.
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 to-
wards 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.
CPUInstallationProcedures
Overheating will seriously damage the CPU and system,
always make sure the cooling fan can work properly to
protect the CPU from overheating.
WARNING!
