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:
MITX-6948 User's Manual
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.
2.4.1 CMOS Clear/Hold Jumper Setting (JCC)CMOS is powered by the on board button cell. Clear CMOS will lead to permanent
elimination of previous system settings(factory default).

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”

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.

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:

ACPI
Advanced Configuration and Power Management. ACPI specifications allow operating system
to control most power of the computer and its add-on.
BIOS
Basic input/output system. It is a kind of software including all in/out control code interface in
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

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.
