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.

Installing Fan
The processor needs specially designed heatsink and fan assembly to cool down and ensure
sufficient air flow inside your system.
After applying thermal grease on the processor and installing it on the socket, please place
heatsink and fan assembly on top of it. Match the four screws to the fixing holes on the board.
Then screw tightly the heatsink and CPU fan assembly onto the board.
Be careful not to over tighten the screws as it can damage the processor or the
CPU board.
Note
Also make sure the fan cable is plugged to fan connector (see section 2.5.1) as indicated in
image below.

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 CAPA880 to meet your application purpose. Below
you can find a summary table of all jumpers and onboard default settings.
Once the default jumper setting needs to be changed, please do it under power-off
condition.

Pin 2, 4, 6 and 8 connect the case-mounted speaker unit or internal buzzer. While
connecting the board to an internal buzzer, please set pin 2 and 4 closed; while
connecting to an external speaker, you need to set pins 2 and 4 opened and connect the
speaker cable to pin 8(+) and pin 2(-).

Pin 9 and 10 connect the power button on front panel to the board, which allows users to
turn on or off power supply.
System Reset Switch
Pin 11 and 12 connect the case-mounted reset switch that reboots your computer
without turning off the power switch. It is a better way to reboot your system for a longer
life of system power supply.
HDD Activity LED
This connection is linked to hard drive activity LED on the control panel. LED flashes
when HDD is being accessed. Pin 13 and 14 connect the hard disk drive to the front

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.
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.
If your computer cannot boot after making and saving system changes with BIOS
setup, you can restore BIOS optimal defaults by setting JP3 (see section 2.4.3).
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.
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.
Some of the navigation keys differ from one screen to another.

Watchdog Timer
A.1
About Watchdog Timer
Software stability is major issue in most application. Some embedded systems are not
watched by operator 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.
A.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.

About Digital I/O
The digital I/O on CPU board has 8 bits. Each bit can be set to function as input or output by
software programming. In default, all pins are pulled high with +5V level (according to main
power). The BIOS default settings are 3 inputs and 5 outputs where all of these pins are set to

Register 0: Input port register.
This register is a read-only port. It reflects the incoming logic levels of the pins, regardless of
whether the pin is defined as an input or an output by Register 3. Writes to this register have
no effect.
The default “X” is determined by the externally applied logic level, normally “1” when no
external signal externally applied because of the internal pull-up resistors.

Register 1: Output port register.
This register reflects the outgoing logic levels of the pins defined as outputs by Register 3. Bit
values in this register have no effect on pins defined as inputs. Reads from this register return
the value that is in the flip-flop controlling the output selection, not the actual pin value.

Register 2: Polarity Inversion register.
This register allows the user to invert the polarity of the Input port register data. If a bit in this
register is set (written with “1”), the corresponding Input port data is inverted. If a bit in this
register is cleared (written with “0”), the Input port data polarity is retained.

Register 3: Configuration register.
This register configures the directions of the I/O pins. If a bit in this register is set, the
corresponding port pin is enabled as an input with high-impedance output driver. If a bit in this
register is cleared, the corresponding port pin is enabled as an output. At reset, the I/Os are
configured as inputs with a weak pull-up to VDD.
