INTRODUCTION

The MS-6312 Flex A TX WH11 mainboard is a high-performance computer
mainboard based on Intel® 810 (810/810 DC100/810e) chipset. The MS-6312
is designed for the Intel® Pentium III(FC-PGA) or CeleronTM processor for
inexpensive business/personal desktop markets.

The Intel® 810 chipset is the first generation Integrated Graphics chipset for
the Intel® CeleronTM processor. The graphics accelerator architecture
consists of dedicated multi-media engines executing in parallel to deliver
high performance 3D, 2D, and motion compensation video capabilities. An
integrated centralized memory arbiter allocates memory bandwidth to
multiple system agents to optimize system memory utilization. A new
chipset component interconnect, the hub interface, is designed into the Intel
810 chipset to provide an efficient communication channel between the
memory controller hub and I/O hub controller.

The series of Intel® 810 chipset contains three core components: the
Graphics and Memory Controller Hub (GMCH), the I/O Controller Hub (ICH)
and the Firmware Hub (FWH). The GMCH integrates a 66/100MHz for 810
and 810 DC100 and 66/100/133 MHz for 810e, P6 family system bus control­ler, 2D/3D graphics accelerator , 100MHz SDRAM controller and high-speed
hub interface for communication with the ICH. The ICH integrates an Ultra
A T A 33(ICHO)/66(ICH) controller , USB host controller, LPC interface
controller, FWH interface conroller , PCI interface controller, AC’97 digital
controller and a hub interface for communication.

The Intel® 82802 Firmware Hub (FWH) component is part of the series of
Intel® 810 chipset. The FWH is key to enabling future security and manage-

ability infrastructure for the PC platform.

processor . The mainboard uses a CPU socket called Socket 370 for easy

CPU installation. The CPU should always have a Heat Sink and a cooling
fan attached to prevent overheating.

2.1-1 CPU Installation Procedures

1 . Pull the lever sideways away

from the socket. Then, raise
the lever up to a 90-degree
angle.

2 . Locate Pin 1 in the socket

and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.

3. Press the lever down to
