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.

The PICO121 is a Pico-ITX board with AMD G-Series Embedded SoC GX-210HA and
GX-210JA 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 DDR3/3L1333/1066MHz
SO-DIMM memory, maximum memory capacity up to 8GB. It also features one Gigabit/Fast
Ethernet, one SATA 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. Moreover, it has one full-size PCI-Express Mini Card and one half-size
PCI-Express Mini Card which provide good expansions for network connecting. Additionally, it
provides you with unique embedded features, such as two serial ports (one RS-232/422/485
and one 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.

Microprocessors
The PICO121 supports AMD G-Series Embedded SoC GX-210HA/GX-210JA processors,
®
®
which enable your system to operate under Windows 7 and Windows 8 environments. The
system performance depends on the microprocessor. Make sure all correct settings are
arranged for your installed microprocessor to prevent the CPU from damages.
5.2
BIOS
The PICO121 uses AMI Plug and Play BIOS with a single 16Mbit SPI Flash.
5.3
System Memory
The PICO121 supports one 204-pin DDR3/3L SO-DIMM socket for a maximum memory of
8GB DDR3/3L SDRAMs. The memory module comes in sizes of 1GB, 2GB, 4GB and 8GB.

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 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.
6.1
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.
If your computer cannot boot after making and saving system changes with BIOS
setup, you can restore BIOS optimal defaults by setting JP7 (see section 2.4.7).
Note
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.
6.2
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.
Some of the navigation keys differ from one screen to another .

You can use Discovery page to find computers capable of ASF or DASH. In the
discovery phase, you can find ASF or DASH manageable computers by giving a range
of IP addresses along with port lists and protocols specified. When computers are found,
they would be shown in the window. By double clicking the found IP, a Manageability
page would appear. Figure 6 shows the results when finding a range of computers from
192.168.0.1 to 192.168.0.255. In addition to the current found devices, computers ever

Administrator as user name and Axiomtek as password to login. After successful login,
a new pop-out window with all supported profiles would appear, such as shown in Figure

Remote Control
In the Remote Control node within Manageability page, you can power on, power off,
power reset, or power recycle the DASH capable computer. You can use the check
box to specify the boot device during next booting. Currently this feature is based on
PLDM for BIOS Control and Configuration Specification and the system needs at
least a one-time boot before you could get attached bootable devices. Figure 8 shows
the snap shot of this feature.
Figure 8: Remote Control and Boot Device Order Change

Console Redirection
The DASH on PICO121 supports two redirection services, text console redirection and
USB redirection services. These two features can be found in the Console Redirection
tab, such as shown in Figure 9.
For USB redirection, users can redirect a pre-created image, CD-ROM drive, USB
dongle and floppy from a remote console as if the device is plugged within the client
computer. You can use the check box to choose an image file (Using image file) or a
physical drive (Using true device) for redirection. By pressing the “…” button, you must
specify the file name or the drive letter used for redirection before starting redirection
service. Besides, except for CD-ROM drive redirection, USB redirection also implements
write operations, which means you can write data from the client side back to the
console side. Moreover, you can check the Using URL and provide a valid URL to do
the same thing. However, you need to setup a web server and put the USB image in that
server before enabling the USB redirection service. Only read operations are supported.
If write operations are needed, please consider using image file or true device.
Text console redirection has the ability to directly enter BIOS setup or pop out a BBS
screen without user’s pressing any key during the booting time. This can reduce the
effort for users when they want to enter BIOS setup or just temporary change boot
device. Whenever a new option is chosen (Normal Boot, Enter BIOS Setup, and Enter
BBS Popout), you should press the Stop TCR button first and then press the Start TCR
button to get it work correctly.
DASH User Guide
87
PICO121 AMD G-Series Embedded SoC Pico-ITX Board
After Start TCR button is pressed, the remote control function would also be invoked,
according to the selected check box in the After Rebooting field. This means that you
can do text console redirection right now without doing any remote operation, or do it the
next time when the computer boots.
Both TELNET and SSH protocols are supported. You can choose to use either of them
according to your need.

Watchdog Timer
B.1
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.
B.2
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.
