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.

Note
To identify the first pin of a header or jumper, please refer to the following
information:
Usually, there is a thick line or a triangle near the header or jumper pin 1.
Square pad, which you can find on the back of the motherboard, is usually
used for pin 1.
2.3 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. The following
illustration shows how to set up jumper.
Before applying power to MANO842 Series, please make sure all of the jumpers are in factory
default position. Below you can find a summary table of all jumpers and onboard default
settings.
Note
Once the default jumper setting needs to be changed, please do it under power-off
condition.

2.3.1 Clear CMOS Select (JP1)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can
clear the CMOS memory of date, time, and system setup parameters by erasing the
CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS,
which includes system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper clip from pins 1-2 (default) to pins 2-3. Keep the clip on pins 2-3
for about 5~10 seconds, then move the clip back to pins 1-2.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter
data.
2.3.2 LVDS VDD Select (JP2)
This motherboard supports voltage selection for flat panel displays. Use this 3x2-pin
p=2.54mm jumper to set up VDD power of the LVDS connector. To prevent hardware
damage, before connecting please make sure that the input voltage of LVDS panel is
correct.

Hardware Description
3.1 Microprocessors
The MANO842 Series supports Intel® Celeron® J1900 processor, which enable your system to
operate under Windows® 7, Windows® 8, Windows® 8.1 and Linux 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 MANO842 Series uses AMI Plug and Play BIOS with a single SPI Flash.
3.3 System Memory
The MANO842 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.

Chapter 4
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. Turn on the computer and press <Del> during the Power On Self Test (POST) to enter
BIOS setup, otherwise, POST will continue with its test routines.
2. Once you enter the BIOS, 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.
Note
If your computer cannot boot after making and saving system changes with BIOS
setup, you can restore BIOS optimal defaults by setting JP1 (see section 2.3.1).
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.
Note
Some of the navigation keys differ from one screen to another.
