Introduction
The 845 Pro (MS-6529) ATX mainboard is a high-performance
computer mainboard based on Intel®82845 & 82801BA chipsets. The 845
Pro (MS-6529) is designed for Intel®Pentium®4 processor in the 423 pin
package that delivers a high performance and professional desktop platform
solution.
The Intel®82845 Memory Controller Hub (MCH) provides the proces-
sor interface, SDRAM interface, AGP interface and hub interface. It supports:
a single processor with a data transfer rate of 400MHz, SDRAM at 133MHz
operation (PC133), AGTL+ host bus with integrated termination supporting
32-bit host addressing, 1.5V AGP interface with 4x SBA/data transfer and 2x/4x
fast write capability, and 8-bit, 66MHz 4x hub interface to the Intel ICH2.
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 flexibility in designing cost-effective system solutions.

D-LED™ & D-Bracket™
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.
If your motherboard supports and installs D-
Bracket™ which also integrates four Diagnostic LEDs, definitions of the
LED signals are the same as D-LED™ as shown below.
