Warning: Turn off PSU (Power Supply Unit) completely (no mains power connected to the

PSU) or leave the Power Connectors unconnected while configuring the board. Otherwise

components (RAM, LAN cards etc.) might get damaged.

Do not use PSU’s without 3.3V monitoring watchdog, which is standard feature in ATX PSU’s.

Running the board without 3.3V connected will damage the board after a few minutes.

Warning: When mounting the board to chassis etc. please notice that the board contains

components on both sides of the PCB which can easily be damaged if board is handled

without reasonable care. A damaged component can result in malfunction or no function at all.

1 Installation procedure

1.1 Installing the board

To get the board running, follow these steps. In some cases the board shipped from KONTRON has already

components like DRAM, CPU and cooler mounted. In this case relevant steps below, can be skipped.

1. Turn off the PSU (Power Supply Unit)

2. Insert the DDR3 DIMM 240pin DRAM module(s)

Be careful to push it in the slot(s) before locking the tabs. For a list of approved DDR3 DIMM modules

contact your Distributor or FAE. DDR3-800/1066 DIMM 240pin (PC3-6400/PC3-8500) are supported.

3. Install the processor

The CPU is keyed and will only mount in the CPU socket in one way. Use the handle to open/ close the

CPU socket. Penryn and Meron CPU’s via mPGA479 or mPGA478 ZIF Socket are supported, refer to

supported processor overview for details.

4. Cooler Installation

Use heat paste or adhesive pads between CPU and cooler and connect the Fan electrically to the

FAN_CPU connector.

5. Connecting Interfaces

Insert all external cables for hard disk, keyboard etc. A CRT monitor must be connected in order to

change CMOS settings.

6. Connect and turn on PSU

Connect PSU to the board by the ATX/BTXPWR and the 4-pin ATX+12V connectors. Alternatively use only

the 4-pin ATX+12V connector if single voltage operation (+12V +/-5%) is requested. Notice that single

voltage operation has limited power support for add-on cards etc. Turn on power.

7. Power Button

The PWRBTN_IN must be toggled to start the Power supply; this is done by shorting pins 16

(PWRBTN_IN) and pin 18 (GND) on the FRONTPNL connector (see Connector description). A “normally

open” switch can be connected via the FRONTPNL connector.

8. BIOS Setup

Enter the BIOS setup by pressing the <Del> key during boot up.

Enter Exit Menu and Load Optimal Defaults.

Refer to the “BIOS Configuration / Setup“ section of this manual for details on BIOS setup.

9. Mounting the board to chassis

When fixing the Motherboard on a chassis it is recommended using screws with integrated washer and

having diameter of ~7mm.

Note: Do not use washers with teeth, as they can damage the PCB and may cause short circuits.

Installation procedure

Note: To clear all CMOS settings, including Password protection, move the Clear CMOS jumper in the

Clear CMOS position (with or without power) for ~10 sec. This will Load Failsafe Defaults and make sure

Secure CMOS is disabled.
