Chapter 2 Installation Instruction2.1 Interface Location and Dimension Diagram

The following picture is the interface index for MITX-6946。when you install your

devices, please consult it and read the following guide. During installation please

care for some devices. Improper installation will lead to system malfunctions.

Note：During installation, in order to protect the parts of the board, please put

on anti-static gloves.

MITX-6946 Interface Location and Dimension Diagram

2.2 Installation StepsPlease refer to the following steps to install your computer:

1．Adjust all Jumpers on MITX-6946 according to the manual;

2．Install CPU and memory；

3．Install other expansion cards；


4

4．Connect all the signal lines, cable, panel-control circuitry and power supply；

5．Start the computer，finish BIOS setup.

Key components of this motherboard are Integrated circuit, and these componentswill be easily damaged by electrostatic influence. So, before installing the motherboard,

you should always keep the following precautions in mind:

1．Hold the board by the edges; don't touch any components or pins on the board.

2．Use a anti-static wrist strap or wear anti-static gloves while getting in touch with integrated

circuit components (such as CPU, RAM).

3 ． Place components in a grounded anti-static bag/pad when these components are

uninstalled.

4．Please make sure the power switch is disconnected before inserting the power plug.

2.3 CPU & Memory InstallationThis motherboard is equipped with 1xDDR3Lslot.Please pay attention to the following two

points when installing memory bank：

1．When fixing, make sure the notch matches SO-DIMM socket and then insert memory bank

into the socket. Press it down to tight the connection.

2．Choose the proper memory bank that supports motherboard specification。

2.4 Jumper SettingPlease setup the jumpers accordingly before installing hardware devices.

Note: How to identify jumper and PIN1 of interface

Please observe the word mark of plug socket, it will use “1” or bold line or triangular

symbols; and please look at the back of PCB,each weld spot has a squar point, that is PIN 1;

Usually there is a withe arrow beside PIN 1.

2.4.1 CMOS Content Clearance /Hold Setting（JCC）CMOS powered by on board button battery. Clean CMOS will lead to a permanent

elimination of the previous system setting and back to the original (default setting) system

settings.

Steps :（1）Turn off the computer, disconnect the power supply ；

（2）Use jumper cap short JCC Pin 1 and Pin 2 for 5~6 sec，Then restore the default

setting of Pin2 and Pin 3.；；

（3）Turn on the computer, then press DEL key into the BIOS setting and reload the

optimized defaults；

（4）Save and exit setting.

Chapter 3 BIOSSETUPAMI BIOS Refresh

BIOS functions as a bridge connecting hardware and operating system. Hardware and

software are upgrading all the time, so when your system goes wrong, for example, your

system can not support the newest CPU, you need to upgrade BIOS to keep up with the latest

technology.

FPT.EXE is a read and write program for FLASH IC loaded with BIOS data on the

motherboard which needs to be run in Shell model.

Please use the bootable DOS U disk to run in Shell model, then run AFUDOS.EXE to

upgrade BIOS write（for example: ****. bin) into FLASH IC.

Order Format：

fpt.exe -f 6946***.bin

If you need to add other parameters, pls add <space>/? after the order format

Remark:

1. BIOS upgrading is only executed when your system goes wrong.

2. Please use the upgrading program in the CD-ROM provided by us or download the

latest version of the upgrading program on-line.

3. Please do not power off or reboot the system when upgrading, otherwise, the BIOS

maybe be damaged or system may not be able to boot again.

4．After upgrading the BIOS, manually load defaults

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 Setup:

1、Power on or reboot the computer, self-detection information will show:

2、When message shows as“Press <DEL> to enter setup, <F11> to Popup menu”, pls press



27

<DEL>, then enter into BIOS SETUP Program.

3、Use the“←↑→↓”to choose the option which your want to modify, press <Enter> and then

the sub-menu.will show.

4、Use the“←↑→↓”and <Enter> to modify the value; press”Enter” to modify BIOS options

that you choose.

5、At any time, press<Esc> can go back to the last menu.

Intel Virtualization Technology

Intel Virtualization is a hypothetical technology used in Intel's CPU. It makes it possible to

run a plurality of OS on a single PC, and VT technology is about to play a very important role in

all types of processors, including dual-core processors. This technology enables processors to

have and/or virtualization technology. Using Vanderpool technology, we can run two operating

systems simultaneously on the same machine. One processor runs one operating system and

the other processor runs another operating system.

Appendix 2: 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 South bridge & North bridge; 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

Cluster Communication Port. A universal serial communication interface, usually adopts

normative DB9 connector.



41

DIMM

Dual-Inline-Memory-Module. It’s a small circuit board with memory chipset, providing 64bit

RAM bus width.

DRAM

Dynamic Random Access Memory. 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

Local Area Network. 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

Power On Self Test. While booting, BIOS will do an uninterrupted testing to the system, including



42

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’s 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
