2.1 Safety Precautions
Always completely disconnect the power cord
from your board whenever you are working on
it. Do not make connections while the power is
on, because a sudden rush of power can
damage sensitive electronic components.
Always ground yourself to remove any static
charge before touching the board. Modern
electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis

2.6 Setting Jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected by a
plastic cover) that slides over the pins to connect them. To “close” a
jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will
have three pins, labeled 1, 2 and 3. In this case you would connect
either pins 1 and 2 or 2 and 3.

Open Closed Closed 2-3
A pair of needle-nose pliers may be helpful when working with
jumpers.
If you have any doubts about the best hardware configuration for your
application, contact your local distributor or sales representative
before you make any change.
Generally, you simply need a standard cable to make most
connections.

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. Non-fatal error messages usually appear on
the screen along with the following instructions:
Press <F1> to RESUME
Write down the message and press the F1 key to continue
the boot up sequence.
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 EMB-945T 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.

Appendix A Programming the Watchdog Timer A-1
Mini-ITX EMB-945T Rev.B
A.1 Programming
EMB-945T Rev.B utilizes ITE 8712 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
After the hardware reset or power-on reset, the ITE 8712 enters the
normal mode with all logical devices disabled except KBC. The
initial state (enable bit ) of this logical device (KBC) is determined
by the state of pin 121 (DTR1#) at the falling edge of the system
reset during power-on reset.
Appendix A Programming the Watchdog Timer A-2
Mini-ITX EMB-945T Rev.B
There are three steps to complete the configuration setup: (1) Enter
the MB PnP Mode; (2) Modify the data of configuration registers; (3)
Exit the MB PnP Mode. Undesired result may occur if the MB PnP
Mode is not exited normally.
(1) Enter the MB PnP Mode
To enter the MB PnP Mode, four 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 four write opera -tions
to the Special Address port (2EH). Two different enter keys are
provided to select configuration ports (2Eh/2Fh) of the next step.
(2) Modify the Data of the Registers
All configuration registers can be accessed after entering the MB
PnP 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 MB PnP Mode
Set bit 1 of the configure control register (Index=02h) to 1 to exit the
MB PnP Mode.
Appendix A Programming the Watchdog Timer A-3
Mini-ITX EMB-945T Rev.B
WatchDog Timer Configuration Registers
Configure Control (Index=02h)
This register is write only. Its values are not sticky; that is to say, a
hardware reset will automatically clear the bits, and does not
require the software to clear them.
