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.

Diagnostic LED
