Introduction 1
The 850 Pro5 (MS-6545 v1.X) ATX mainboard is a high-performance
computer mainboard based on Intel®82850 chipset. It is optimized to support
Intel®Pentium®4 processors for high-end business/personal desktop markets.
The Intel®850 chipset supports 64-byte cache line size and a 32-bit host
addressing, allowing the processor to access the chipset’s memory address
space. It also provides 4x AGP data transfers and AGP Fast Write capability.
The Intel®850 chipset features a dual channel Direct RDRAM memory
operating in lock-step using RSL technology. It is a highly-flexible chipset
which is designed to extend the basic graphics/multimedia PC platform up to
the mainstream performance desktop platform.
The Intel®82801BA (ICH2) chipset is a highly integrated multifunctional
I/O Controller Hub that provides the interface to the PCI Bus and integrates
many of the functions needed in today’s PC platforms. It communicates with
the host controller over a dedicated hub interface and provides added flexibil-
ity in designing cost-effective system solutions.

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

D-LED™ & D-Bracket™ (Optional)
The D-LED™ uses graphic signal display to help
users understand their system. Four LEDs embedded in
the mainboard 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.
The D-Bracket™ which integrates four Diagnostic LEDs is optional.
Definitions of the D-Bracket™ LED signals are the same as D-LED™ as shown
below.

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.
