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.

2.3 Installing Thermal Solution
For thermal dissipation, a thermal solution enables the CEM700’s components to dissipate
heat efficiently. All heat generating components are thermally conducted to the heatsink in
order to avoid hot spots. Below images illustrate how to install the thermal solution on
CEM700.
1. There is a protective plastic covering on the thermal pads. This must be removed before
the heatsink can be mounted.
2. Each heatsink is designed for a specific CEM module. The thermal pads on the heatsink
are designed to make contact with the necessary components on the CEM module.
When mounting the heatsink you must make sure that the thermal pads on the heatsink
make complete contact (no space between thermal pad and component) with the
corresponding components on the CEM module. This is especially critical for CEM
modules that have higher CPU speeds (for example 1.0GHz or more) to ensure that the
heatsink acts as a proper thermal interface for cooling solutions.
3. This CPU module has six assembly holes for installing heatsink plate. Use screws to
secure heatsink plate to the CEM700. Be careful not to over-tighten the screws.

2.4 Switch Settings
Properly configure switch settings on the CEM700 to meet your application purpose. Below
you can find a summary table of switch and onboard default setting.
Note
Once the default switch setting needs to be changed, please do it under power-off
condition.
Switch

Default: Normal Operation
SW1-2 OFF
2.4.1 Auto Power On and Restore BIOS Optimal Defaults (SW1)
If dip1 of SW1 (SW1-1) is set to ON position, the system will be automatically power on
without pressing soft power button. If this switch is set to OFF position, it is necessary to
manually press soft power button to power on the system.
The dip2 of SW1 (SW1-2) is for restoring BIOS default status. Flip SW1-2 to ON position
for a few seconds then flip it back to OFF position. Doing this procedure can restore
BIOS optimal defaults.

Hardware Description
3.1 Microprocessor
The CEM700 supports Intel® Xeon D
®
and Pentium D® processors, which enables your system
to operate under Windows® 7/10, Windows® Server 2012/2016 and Linux environments. The
system performance depends on the microprocessor. You must install the heatsink or cooler
carefully and properly to prevent damage.
3.2 BIOS
The CEM700 uses AMI Plug and Play BIOS with a single 128Mbit SPI Flash.
3.3 System Memory
The CEM700 supports two 260-pin DDR4 SO-DIMM sockets for maximum memory capacity
up to 32GB. The memory module can come in sizes of 4GB, 8GB and 16GB.

AMI BIOS Setup Utility 21
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 the <Del> key immediately.
2. 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.
Note
If your computer cannot boot after making and saving system changes with BIOS
setup, you can restore BIOS optimal defaults by setting SW1-2 (see section 2.4.1).
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.

After the system stops working for a while, it can be auto-reset by the watchdog timer. The
integrated watchdog timer can be set up in the system reset mode by program.
Assembly sample code :
mov dx,fa10 ; 5 seconds (Maximum is 65535 seconds; fill in
; 0xFA10 and 0xFA11 register, ex: 0xFA11=0x01,
; 0xFA10=0x68 means 360 seconds)
mov al,05
out dx,al
mov dx,fa12 ; Enable WDT
mov al,01
out dx,al
A.2 About GPIO
The onboard GPIO or digital I/O has 8 bits (DIO0~7). Each bit can be set to function as input or
output by software programming. In default, all pins are pulled high with +3.3V level (according
to main power). The BIOS default settings are 4 inputs and 4 outputs where all of these pins
are set to 1.
Assembly sample code :
mov dx,fa31 ; Set DIO 0-7 to Output
mov al,00
out dx,al
mov dx,fa32 ; Set DIO 4-7 to High
mov al,f0
out dx,al
mov dx,fa31 ; Set DIO 0-7 to Input
mov al,ff

The BIOS Flash utility is a new helpful function in BIOS setup program. With this function you
can easily update system BIOS without having to enter operating system. In this appendix you
may learn how to do it in just a few steps. Please read and follow the instructions below
carefully.
1. In your USB flash drive, create a new folder and name it “Axiomtek”, see figure below.
2. Copy BIOS ROM file (e.g. CEM700.005) to “Axiomtek” folder.
3. Insert the USB flash drive to your system.
4. Enter BIOS setup menu and go to Advanced\Utility Configuration. Select BIOS Flash

5. BIOS automatically detect all USB drive(s) attached to the system. In this example only
one USB drive is attached to the system. That’s why, you can see only one device is
displayed in figure below.
6. Select the USB drive containing BIOS ROM file you want to update using the <> or
<> key. Then press <Enter> to get into “Axiomtek” folder.
7. Now you can see the BIOS ROM file on the screen, press <Enter> to select.
8. Select Start to flash system BIOS option to begin updating procedure.
