ESD Precautions
Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

CEM820 Intel®Pentium®M/Celeron®COM ExpressTM Type-II Module
Introduction 1
C h a p t e r 1
Introduction
The CEM820 is a new and practically finest COM ExpressTM Type-II
Module in the market with embedded Socket 478 and BGA type for
Intel®Pentium®M and Celeron®M processors at 400/533 MHz FSB,
and integrates Intel®chipsets 915GME & ICH6M (for socket 478) and
910GMLE & ICH6M (for BGA type).
This powerful module supports excellent Multiple I/O, LVDS LCD,
Fast/Gigabit Ethernet, AC'97/HD digital Audio, one PATA -100, two
SATA and eight USB 2.0 ports to make all in one single module as
computing engine. It provides one PCI Express X16 for graphics or
SDVO, four PCI Express X1, and four 32-bit/33MHz PCI master for
expansion purpose.
It can achieve the best stability and reliability that makes your system
perform the most endurable operation in any critical environments.
The built-in Watchdog Timer has enhanced the system reliability that
achieves a unique feature to distinguish itself from other boards.
