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.

Chapter 1
Introduction
The PICO100 is a Pico-ITX board with AMD G-Series APU T40E/T40R and Fusion Controller
Hub A50M that delivers outstanding system performance through high-bandwidth interfaces,
multiple I/O functions for interactive applications and various embedded computing solutions.
The board has one 204-pin unbuffered SO-DIMM socket for DDR3 1066MHz SO-DIMM
memory, maximum memory capacity up to 4GB. It also features one Gigabit/Fast Ethernet,
one serial ATA port with transfer rates up to 6Gb/s, four USB 2.0 high speed compliant, and
built-in high definition audio codec that can achieve the best stability and reliability for industrial
applications. Additionally, it provides you with unique embedded features, such as two serial
ports (2x RS-232) and Pico-ITX form factor that applies an extensive array of PC peripherals.
The board can be enhanced by its built-in watchdog timer function, a special industrial feature
not commonly seen on other motherboards.

Please pay attention to that fan cable is on the right side as the below photo.
For thermal dissipation, a heatspreader enables the PICO100’s components to dissipate heat
efficiently. Below images illustrate how to install the heat spreader.
Installing Heatspreader
The PICO100 has four assembly holes for installing heatspreader plate. Align both of them and
use the four screws to firmly secure the heatspreader plate to the PICO100. Be careful not to
over-tighten the screws.

Jumper Settings
Jumper is a small component consisting of jumper clip and jumper pins. Install jumper clip on 2
jumper pins to close. And remove jumper clip from 2 jumper pins to open. Below illustration
shows how to set up jumper.
Properly configure jumper settings on the PICO100 to meet your application purpose. Below
you can find a summary table of all jumpers and onboard default settings.
Note: Once the default jumper setting needs to be changed, it is suggested to be
set under power-off.

AMI BIOS Setup Utility
The AMI UEFI BIOS provides users with a built-in setup program to modify basic system
configuration. All configured parameters are stored in a 16MB flash chip to save the setup
information whenever the power is turned off. This chapter provides users with detailed
description about how to set up basic system configuration through the AMI BIOS setup utility.
4.1
Starting
To enter the setup screens, follow the steps below:
1.
2.
Turn on the computer and press the <Del> key immediately.
After you press the <Del> key, the main BIOS setup menu displays. You can access the
other setup screens from the main BIOS setup menu, such as the Advanced and Chipset
menus.
Note:
If your computer can not boot after making and saving system changes with Setup,
you can restore BIOS optimal defaults by setting JP5 (see section 2.4.3).
It is strongly recommended that you should avoid changing the chipset’s defaults. Both AMI
and your system manufacturer have carefully set up these defaults that provide the best
performance and reliability.
4.2
Navigation Keys
The BIOS setup/utility uses a key-based navigation system called hot keys. Most of the BIOS
setup utility hot keys can be used at any time during the setup navigation process. These keys
include <F1>, <F2>, <Enter>, <ESC>, <Arrow> keys, and so on.
Note: Some of the navigation keys differ from one screen to another.

Watchdog Timer
About Watchdog Timer
Software stability is major issue in most application. Some embedded systems are not
watched by human for 24 hours. It is usually too slow to wait for someone to reboot when
computer hangs. The systems need to be able to reset automatically when things go wrong.
The watchdog timer gives us solution.
The watchdog timer is a counter that triggers a system reset when it counts down to zero from
a preset value. The software starts counter with an initial value and must reset it periodically. If
the counter ever reaches zero which means the software has crashed, the system will reboot.
How to Use Watchdog Timer
The I/O port base addresses of watchdog timer are 2E (hex) and 2F (hex). The 2E (hex) and
2F (hex) are address and data port respectively.
Assume that program A is put in a loop that must execute at least once every 10ms. Initialize
watchdog timer with a value bigger than 10ms. If the software has no problems; watchdog
timer will never expire because software will always restart the counter before it reaches zero.
