ESD Precautions
Integrated circuits on computer boards are sensitive to static electricity.
To avoid damaging chips from electrostatic discharge, observe the
following precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

C h a p t e r 1
Introduction
The SBC856A1 is a VIA EDEN 400/667/800/1G FANLESS -based
POS board with Ethernet and audio interface. Designed with the
space-limited applications in mind, the SBC856A1 is practically the
finest embedded PIII-level in existence. SBC856A1 can adapt a wide
variety of VIA EDEN microprocessors by BIOS auto-detection. To
simplify system integration, it packs embedded provisions such as
super I/Os, Graphics with DualView features, LCD (TTL & LVDS),
Ethernet (Gigabit & Fast), solid state disk, all on a single board.
Unique embedded features such as 4 serial ports (3 x RS-232, 1 x
RS-232/422/485) with +5V/12V power capability and simple
automation control are exclusive design features that allow adoption
of an extensive array of PC peripherals.
