Introduction
Welcome to the POS-566/566L 550MHz K6®-3 / Pentium
Processor Multimedia POS Control Board Computer. The POS-
566/566L board is a LPX Spec. board, which equipped with high
performance Pentium®CPU, LCD/CRT and 10/100Mbps Ethernet,
designed for the system manufacturers, integrators, or VARs that
want to provide all the performance, reliability, and quality at a
reasonable price.
This board has a built-in DiskOnChip™(DOC) Flash Disk Socket
for embedded application. The DOC Flash Disk is 100% software
compatible to hard disk. User can use any DOS command without
any extra software utility. The DOC currently is available from 2MB
to 144MB.
The POS-566/566L provides three 168-pin DIMM sockets for its
on-board DRAM with max. 768MB. DIMM module is 3.3V SDRAM.
The board’s Realtek RTL8139 IEEE 802.u network chipset
provides 10MBps or 100MBps Ethernet with auto-sensing function.
In addition, the POS-566 is also Creative Sound Blaster 16 and
Roland MPU401 UART Mode compatible. This feature is not
available in POS-566L.
With its Isolated Digital I/O control for field site application, this

Installation
This chapter describes how to install the POS-566/566L. The
layout of POS-566 is shown on the next page and the Unpacking
Precautions that you should be careful with are described on the
following page. Also included is the jumpers and switches setting
for this board’s configuration, such as: CPU type selection,
system clock setting and Watchdog timer.

2.2 Unpacking Precautions
Some components on POS-566/566L are very sensitive to static
electric charges and can be damaged by a sudden rush of power. To
protect it from unintended damage, please, follow these precautions:
üGround yourself to remove any static charge before touching your
POS-566/566L. You can do it by using a grounded wrist strap at all
times or by frequently touching any conducting materials that is
connected to the ground.
üHandle your POS-566/566L by its edges. Don’t touch IC chips, leads
or circuitry if not necessary.
üDo not plug any connector or jumper while the power is on.
üDo not put your POS-566/566L unprotected on a flat surface because
it has components on both sides.

If you use AMD K6-2/350MHz to run Win95, oftenly the message
‘Windows protection error. You need to restart your
computer’will appear. This is AMD CPU’s problem. To debug
this problem, you must download and run the program:
