Power Management features (Basic)
Using power-saving states
The system provides the two power-saving states: Sleep and
Hibernation.
When Sleep is initiated, the power lights blink and the screen clears.
Your working task is saved to memory. Exiting Sleep is faster than
exiting Hibernation. If the system is in the Sleep state for an extra
period or if the battery reaches a critical battery level while in the
Sleep state, the system initiates Hibernation.
When Hibernation is initiated, your work is saved to a hibernation file
on the hard drive and the system turns off.
vi
Embedded Controller AEC-6612
Initiating and exiting Sleep
The system set the Sleep mode after 30 minutes of inactivity when
running on external power. You can change to none Sleep mode if the
system needs to be active at all time. The default power management
settings have been selected for compliance with ENERGY STAR
and are recommended by the ENERGY STAR
®
program for optimal
®
,
energy savings.
Using power plans
You can choose your own power plan which is a collection of system
settings that manages how the system uses power. Power plans can
help you conserve power or maximize performance.

1.1 Introduction
The newest Boxer series AEC-6612 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 AEC-6612 is designed for indoor environments due to the
following reasons; first, the AEC-6612 offers low power
consumption system that while operating in ambient temperatures
ranging from -20° to 60°C. The MTBF (Mean Time Before Failure)
rating states that the AEC-6612 can operate up to 50,000 hours at
40°C ambient temperature, which indicates its careful and long-life
design.
The AEC-6612 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.

Chapter 3 AMI BIOS Setup 3-1
Embedded Controller AEC-6612
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 AEC-6612 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.
Chapter 3 AMI BIOS Setup 3-2

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.
Entering Setup
Power on the computer and press <Del> or <F2> immediately. This
will allow you to enter Setup.
Main
Set the date, use tab to switch between date elements.
Advanced
Enable disable boot option for legacy network devices.

Watchdog Timer
Appendix A Programming the Watchdog Timer A-1
Embedded Controller AEC-6612
A.1 Programming
AEC-6612 utilizes W83627DHG-P chipset as its watchdog timer
controller.
Below are the procedures to complete its configuration and the
AAEON intial watchdog timer program is also attached based on
which you can develop customized program to fit your application.
Configuring Sequence Description
Unlock W83627DHG
Select register of
watchdog timer
Enable the function of
the watchdog timer
Use the function of the
watchdog timer
Lock W83627DHG
There are three steps to complete the configuration setup:
(1) Enter the W83627DHG config Mode
(2) Modify the data of configuration registers
Appendix A Programming the Watchdog Timer A-2
Embedded Controller AEC-6612
(3) Exit the W83627DHG config Mode. Undesired result may
occur if the config Mode is not exited normally.
(1) Enter the W83627DHG config Mode
To enter the W83627DHG config Mode, two special I/O write
operations are to be performed during Wait for Key state. To
ensure the initial state of the key-check logic, it is necessary to
perform two write operations to the Special Address port (2EH).
The different enter keys are provided to select configuration ports
(2Eh/2Fh) of the next step.
Address Port Data Port
87h,87h: 2Eh 2Fh
(2) Modify the Data of the Registers
All configuration registers can be accessed after entering the config
Mode. Before accessing a selected register, the content of Index
07h must be changed to the LDN to which the register belongs,
except some Global registers.
(3) Exit the W83627DHG config Mode
The exit key is provided to select configuration ports (2Eh/2Fh) of
the next step.
