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.

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 CAPA881 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 CPU 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(-).
Power On/Off Button
Pin 9 and 10 connect the power button on front panel to the CPU 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
panel HDD LED, pin 13 is assigned as cathode(-) and pin 14 is assigned as anode(+).

Microprocessors
The CAPA881 supports Intel® CoreTM i7 /i5 /i3 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.
3.2
BIOS
The CAPA881 uses AMI Plug and Play BIOS with a single 16Mbit SPI Flash.
3.3
System Memory
The CAPA881 supports one 204-pin DDR3L SO-DIMM socket for maximum memory capacity
up to 8GB DDR3L 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.
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 JP6 (see section 2.3.4).
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.
