TheMS-6176MicroLPXWH4mainboardisahigh-performanceall-in-one
computermainboard based on Intel®810 (810/810 DC100/810e) chipset. The
MS-6176 is designed for the Intel®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
GraphicsandMemoryControllerHub(GMCH),theI/OControllerHub(ICH)
andtheFirmware Hub (FWH). The GMCH integrates a 66/100MHz for 810
and810DC100and66/100/133MHzfor810e,P6familysystembuscontrol-
ler, 2D/3D graphics accelerator, 100MHz SDRAM controller and high-speed
hub interface for communication with the ICH. The ICH integrates an Ultra
ATA33(ICHO)/66(ICH)controller,USB hostcontroller,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 seried of
Intel®810 chipset. The FWH is key to enabling future security and manage-
ability infrastructure for the PC platform.

Hardware Installation
2.1 Central Processing Unit: CPU
The mainboard operates with Intel®CeleronTM 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.

3. Press the lever down to
complete the installation.
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.

The mainboard CPU Bus Frequency can be set through BIOS setup
If CPUClock = 66MHz
Core/Bus ratio = 3.5
then CPU core speed = Host Clock x Core/Busratio
= 66MHzx3.5
= 233MHz

2.1-3 Fan Power Connectors: CPUFAN & SYSFAN
These connector support system cooling fan with + 12V. It supports three
pin head connector. When connecting the wire to the connector, always
take note that the red wire is the positive and should be connected to the
+12V, the black wire is Ground and should be connected to GND. If your
mainboard has System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System Hardware Monitor will count and report the fan rotation
speed.

2.2 Clear CMOS Jumper: JBAT1
A battery must be used to retain the mainboard configuration in CMOS
RAM. To retain the on-board battery you must always short pins 1-2 of
JBAT1.
Note: You can clear CMOS by shorting 2-3 pin, while the system is
off. Leave for about 5 to 10 seconds. Then, return to 1-2 pin
position. Avoid clearing the CMOS while the system is on for
it will damage the mainboard. Always unplug the power cord
from the wall socket.

b. HowtoinstallaDIMMModule
1. The DIMM slot has two Notch Key called “VOLT and DRAM”, so
the DIMM memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM slot.
Then, push it in.
3. Close the plastic clip at the side of the DIMM slot.
