1.1 Introduction
The newest Boxer series TKS-G20-LN05 Rev.B has been
introduced by AAEON and it utilizes Intel
®
Atom™ processor. In this
era of information explosion, the advertising of consumer products
will not be confined to the family television, but will also spread to
high-traffic public areas, like department stores, the bus,
transportation station, the supermarket etc. The advertising
marketing industry will resort to every conceivable means to
transmit product information to consumers. System integrators will
need a multifunction device to satisfy commercial needs for such
public advertising.
The TKS-G20-LN05 Rev.B is designed for indoor environments due
to the following reasons; first, the TKS-G20-LN05 Rev.B offers low
power consumption system that while operating in ambient
temperatures ranging from 0° to 45°C.
The TKS-G20-LN05 Rev.B is a standalone high performance
controller designed for long-life operation and with high reliability. It
can replace traditional methods and become the mainstream
controller for the multimedia entertainment market.

Note:
Issue: COM port limitation for the speed test during the communication.
Root Cause:
In serial communication, data bits received at the serial port are bundled
into a byte and transmitted into the serial port hardware buffer. From the
buffer, the byte is sent into the CPU. If a new byte arrives before the byte
in the buffer is moved into the CPU, a Hardware Overrun Error occurs.
Solution:
1. Try hardware handshaking.
2. See if the UART is an older un-buffered version or a new buffered
UART (such as a 16550A or 16750). You should use a buf fered UART
for the reasons discussed above.
3. Change the Receive (Rx Trigger) buffer to 8, 4, or 1 (1 is a last resort).
4. For the product, the speed setting of Series Port (COM) is under
9600bps.

Chapter 3 AMI BIOS Setup 3-1
Embedded Controller TKS-G20-LN05 Rev.B
3.1 System Test and Initialization
These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few short
beeps or see an error message on the screen. There are two kinds
of errors: fatal and non-fatal. The system can usually continue the
boot up sequence with non-fatal errors.
System configuration verification
These routines check the current system configuration against the
values stored in the CMOS memory. If they do not match, the
program outputs an error message. You will then need to run the
BIOS setup program to set the configuration information in memory.
There are three situations in which you will need to change the
CMOS settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The TKS-G20-LN05 Rev.B CMOS memory has an integral lithium
battery backup for data retention. However, you will need to replace
the complete unit when it finally runs down.

3.2 AMI BIOS Setup
AMI BIOS ROM has a built-in Setup program that allows users to
modify the basic system configuration. This type of information is
stored in battery-backed CMOS RAM so that it retains the Setup
information when the power is turned off.
