Chapter 1 Product Introduction
1.1 Overview
A low profile mini-ITX board with Intel next generation Atom N2800/D2550 Processor. The
MITX-6934 is a new addition to NORCO's extensive line of thin Mini-ITX embedded boards.
Running on the the latest Intel Atom "Cedarview" processor, this network security and
communication appliance board boasts clock speeds of 1.86GHz with both single and dual
core offerings. Another great feature essential to network security appliances is the LAN
bypass feature. In the unlikely event that this device should fail, or perhaps during a power
failure, the LAN bypass feature allows data to flow through passively instead of terminating at
the device. The MITX-6934 also gives you the option to boot directly from a CF card, or from a
standard HDD or SSD drive via the SATA II port. In addition to the 2 external, and 4 internal
USB 2.0 ports, the I/O on this system includes two serial ports one via RJ45 and the other via
pin-header. This feature packed embedded board is capable of supporting 64-bit operating
systems, making it ideal for any network security or communications applications.

LAN Bypass feature removes a single point of failure so that essential business communication
can continue while a network failure is diagnosed and resolved. In the event of a power,
hardware or software failure. Hardware Bypass will automatically activate,allowing network
traffic to continue. Traffic between the LAN and WAN is allowed without interruption. In the
event of a system hang, power down, hardware or software failure, Hardware Bypass will
automaticallyactivate allowing network traffic to continue.

Chapter 3 BIOS SETUP
AMI BIOS Upgrading
It is true that hardware and software are upgrading all the time. When your IPC can not support
the newest processor (for example), you should upgrade the BIOS to try to keep up with the
latest technology. Upgrading (or flashing) the BIOS is not an easy attempt. To make sure
upgrade succeed, please follow the instruction below:
AFUDOS.EXE is the program for BIOS to modify and upgrade，need to be run in DOS mode.
Use boot disk load DOS, run AFUDOS.EXE and write the newest file: XXXX.ROM into the
Flash IC.
Order Format:
A:\ Afudos XXXX.rom / P /B /N /X
If you need to add other parameters, please add <space>/? after the order format.
Remarks:
1. Upgrading BISO may cause your system crash, so please operate carefully.
2. Please use the upgrading program in the CD-ROM provided by us or download the latest
program on related websites
3. Please do not power off or reboot the system when upgrading, otherwise, the BIOS maybe
be damaged.
4. After BIOS flash, to load default optimum manually
5. Please backup your BIOS before upgrading.
AMI BIOS Description
When the computer is power on, BIOS will conduct self-diagnosis to its hardware on
motherboard and configure hardware parameter, finally the operating system will take control.
BIOS is the communication bridge between hardware and O/S. Correct configuration of BIOS
is critical for maintaining system stability and its optimized performance.
BIOS Settings
1. Power on or reboot the computer, self-detection information will show:
2. When message shows as "Press <DEL> to enter setup"，pls press <DEL>, then enter into
BIOS SETUP Program.
3. Use the “←↑→↓”to choose the option which your want to modify, press <Enter> to go to
Page 30
MITX-6934 Intel Cedar Trail Powered 4 Gigabit Mini-ITX Motherboard

its sub-menu.
4. Use the “←↑→↓”and <Enter> to modify the value of the chosen option, then press”Enter”
to modify BIOS options that you choose
5. At any time, press<Esc> can go back to the father-menu.
Remark! BIOS settings have direct impatcs to computer performance. Incorrect configurations
will cause damage to the computer and even lead to system halted. Please use BIOS default
settings to recovery system. As our company is aways ceaselessly update the BIOS SETUP
Utility, so, following BIOS SETUP screens are only for your reference. Some may be

Hyper-Threading
Disable or enable the Hyper-Threading Technology.
Intel® Hyper-Threading Technology uses resources efficiently, enabling multiple threads to run
on each core, and increasing processor throughput.
Execute Disabled Bit
When this field is set to Disabled, it will force the XD feature flag to always return to 0. XD can
prevent certain classes of malicious buffer overflow attacks when combined with a supporting
OS (Windows Server 2003 SP1, Windows XP SP2, SuSE Linux 9.2, RedHat Enterprise 3
Update 3).
Limit CPUID Maximum
The CPUID instruction of some newer CPUs will return a value greater than 3. The default is
Disabled because this problem does not exist in the Windows series operating systems. If you
are using an operating system other than Windows, this problem may occur. To avoid this
problem, enable this field to limit the return value to 3 or lesser than 3.

Appendix 3: Glossary
ACPI
Advanced Configuration and Power Management. ACPI specifications allow O/S to control
most power of the computer and its add-ons
Windows 98/98SE，Windows 2000 and Windows ME all support this function, which enable
users to manage the system power flexibly.
BIOS
Basic input/output system. It’s a kind of software including all in/out control code interface in PC.
It will do hardware testing while system is booting, then system runs, it provides an interface
between OS and hardware. BIOS is stored in a ROM chip.
BUS
In a computer system, it is the channel among different parts for exchanging data; it’s also a
group of hardware lines. BUS here refers to part lines inside CPU and main components of
memory.
Chipset
Integrated chips for executing one or more functions. Here “Chipset” refers to system level
chipset structured by Southbridge & Northbridge; it determines motherboard’s structure and
main functions.
CMOS
Complementary Metal-Oxide Semiconductor, a widely used semiconductor with the
characteristic of high speed but low-power-consumption. CMOS here refers to part of reserved
space in on-board CMOS RAM, for saving date, time, system information and system
parameter etc.
COM
Computer-Output Microfilmer. A universal serial communication interface, usually adopts
normative DB9 connector.
Page 50
MITX-6934 Intel Cedar Trail Powered 4 Gigabit Mini-ITX Motherboard
40
DIMM
Dual-Inline-Memory-Module. It’s a small circuit board with memory chipset, providing 64bit
RAM bus width.
DRAM
Dynamic Random Access Memorizer. It’s a normal type of universal memory often with a
transistor and a capacitance to store 1 bit. With the development of the technology, more and
more types of ORAM with various specifications exist in computer application, such as SDRAM,
DDR SDRAM and RDRAM
I2C
I2C（Inter－Integrated Circuit）, generically referred to as two-wire interface, is a multi-master
serial single-ended computer bus invented by Philips that is used to attach low-speed
peripherals to a motherboard, embedded system, cellphone, or other electronic device.
LAN
Network interface. Network grouped by correlative computers in a small area, generally in a
company or a building. Local area network is generally buildup by sever, workstation, some
communication links. Terminals can access data and devices anywhere through cables so that
many users can share costly device and resource.
LED
Light-Emitting Diode. a semiconductor device that shines when power supply is connected,
often used to denote info directly by light, for example, to denote power on or HDD work
normally.
PnP
Plug-and-Play. It is a specification that allows PC to configure its external devices automatically
and can work independently without the manual operation by its user . To achieve this function,
its BIOS should be able to support PnP and a PnP expansion card.
POST
Self-test when power on. While booting, BIOS will do an uninterrupted testing to the system,
Page 51
MITX-6934 Intel Cedar Trail Powered 4 Gigabit Mini-ITX Motherboard
41
including RAM, keyboard, hard disk driver etc. to check if all the components are in normal
situation and work well.
PS/2
A keyboard & mouse connective interface specification developed by IBM.PS/2 is a DIN
interface with only 6PIN; it also can connect other devices, like modem.
USB
It is the Universal Serial Bus for short. A hardware interface adapts to low speed external
devices, and is always used to connect keyboard, mouse etc. One PC can connect maximum
127 USB devices, providing 12Mbit/s transmit bandwidth；USB supports hot swap and multi-
data stream, namely, you can plug USB devices while system is running, system can
auto-detect and makes it work.
