Chapter Two Installation Specification2.1 Interfaces Location & Dimension

Following picture illustrates the interfaces location and dimension of MITX-6948. Please

take care of some components during the installation. Improper installation may leads to

system failure.

Note: In case of any electrostatic damage caused to some components, please wear

anti-static gloves to install the motherboard.

MITX-6948 Interfaces Location & Dimension

2.2 Installation StepsPlease refer to following steps to assemble your computer:


4

1．Adjust all jumpers on board MITX-6948 according to the user manual；

2．Install Memory；

3．Install other expansion cards；

4．Connect all signal lines, cables, control panel circuit and power supply unit.；

5．Start the computer and complete BIOS Settings

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

always keep the following precautions in mind:

1．Hold the board by edges and don’t touch any components, plugs or socket pins.

2．Wear anti-static gloves/wrist strap while touching the integrated circuit components, such as

CPU, RAM, etc.

3．Put those unused or uninstalled components in static shielding bags or trays.

4．Please first check the power switch is off before connecting the power plug.

2.3 Memory InstallationBoard with 1xDDR3L slot, Please pay attention to following two points when installing the

memory bank：

1．Align the notch of the DIMM memory bank with that of the socket. Insert the memory bank

into the socket and press the memory bank vertically and evenly on both sides until the

memory bank enters into the slot.

2．Select the memory bank that matches your motherboard.

2.4 Jumper SettingsPlease refer to following instructions to do jumper settings before installing your hardware

devices.

Remark: How to identify the PIN1 of all jumpers and interfaces: Please observe the word

mark on the side of the plug socket, which will be a “1” or bold line or triangular symbol; And

please look at the back of PCB, each with a square shape will be the PIN 1; and all the jumpers’

PIN1 have a white arrow on the side.

Chapter Three BIOS SET UPAMI BIOS Refresh

BIOS provides the underlying driver of hardware resources and is the bridge between

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 the FLASH IC program for BIOS to upgrade, which needs to be run in Shell

mode.

Please use DOC U disk to load Shell, then run FPT.EFI to upgrade BIOS（ for example:

write XXXX. bin into FLASH IC）.

Specific Command：

fpt.exe -f 6948***.bin

If you need to add other parameters after the order format, please add space /？

Reminder：

1．BIOS Flash is only executed when it is necessary.

2．Please use the BIOS SETUP programs in the CD-ROM provided by us or download the

latest version on related websites.

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

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

4．After finishing BIOS flash, users need to manually select to enter BIOS SETUP LOAD

DEFAULT to optimize

5．To prevent any unexpected problems, please backup your BIOS in advance.

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.

Correct configuration of BIOS is critical for maintaining system stability and its optimized

performance.

BIOS Set up

1、Power on or restart the system, self-detection message will display on the screen.

2、、When system pops out the prompt“Press <DEL> to enter setup, <F11> to Popup menu”


26

please press <Del> key to enter BIOS setup interface.

3、Use the“←↑→↓”to select the option which you want to modify, press <Enter> to go to the

sub-menu.

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 former menu.

This is the specific information for displaying the CPU.

Limit CPUID Maximum

CPUID refers to CPU information， including model, CPU family, cache size, clock speed

and label, as well as the number of transistors, pin type, size and so on. The BIOS settings for

Intel platforms are usually Limit CPUID MAX to 3. The implication is to limit the return value of

CPUID instructions to more than 3. Because the return value of more than 3 may cause some

operating systems to act incorrectly, generally setting this option to [Disabled] in Windows

system can achieve better overclocking effect. Default: [Disabled].

Execute Disable Bit

Execution forbidden bit is a hardware feature of Intel CPU, which can make CPU avoid

some malicious attacks based on buffer overflow virus. In addition, the execution of forbidden

bits requires OS cooperation such as Windows XP SP2 and Windows Server 2003 SP1 to work

properly. The principle of implementation is to divide several areas in memory by the processor.

Some areas can execute application code, while others are not allowed. Set value:

PC. It will do hardware testing while system is booting. BIOS provides is stored in a ROM chip.

BUS

In a computer system, it is the channel among different parts for exchanging data; it is also a

set of hardware lines. BUS here refers to part lines inside CPU and the main components of

system memory.

Chipset

Chipset is an integrated set of chips for executing one or more related functions。Here it refers

to a system level chipset structured by South Bridge & North Bridge; Chipset decides the

structure and main functions of motherboard.

CMOS

Complementary Metal-Oxide Semiconductor, which is a widely used semiconductor with the

characteristics of high-speed and low-power. COMS here refer to part of space 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 DB 9 connector.

DIMM

Dual-Inline-Memory-Modules. It is a small circuit board with memory chipset providing 64 bit

memory bus width.


43

DRAM

Dynamic Random Access Memory. It’s a general type of memory for regular computer which

usually store 1 bit with a transistor and a capacitance. With the development of the technology,

more and more types of DRAM with different specifications exist in computer applications. For

example: SDRAM/DDR SDRAM/RDRAM.

I2C

Inter－Integrated Circuit Bus is a two-wire serial bus developed by PHILIPS Company, which is

used to connect micro-controller and its peripheral equipment.

LAN

Local Area Network. Network grouped by correlative computers in a small area, generally in a

company or a building. Local area network is buildup by sever, workstation, some

communications links. Terminals can access data and devices anywhere through cables, which

enables users to share costly devices and resource.

LED

Light-Emitting Diode. A semiconductor device that lighted when power supply is connected, It is

often used to indicate information directly, for example, to indicate power on or HDD working

normally.

PnP

Plug-and-Play. It is a specification that allows PC to configure its external devices automatically

and it works independently without the manual operation. To achieve this function, BIOS should

be able to support PnP and a PnP expansion card.

POST

Power On Self Test. While the system is booting, BIOS will keep testing the system which

including RAM, keyboard, hard disk driver to check if all the components are connected directly

and function well.

PS/2

A keyboard & mouse connective interface specification developed by IBM.PS/2 is a DIN


44

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 peripherals,

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 on.
