Chapter 2 Quick Installation Guide
2.1 Layout
The following picture is interface index for EMB-3682, when you install your devices,
please consult it and read the following guide. During installation please care for
some devices. Incorrect installation will lead to malfunctions.
Remark：During installation, please put on antistatic gloves in case of any damage
EMB-3682 Interface Location
2.2 Jumper Setting
*REMIND：
Jumpers are located on the mainboard, they represent clear CMOS jumper JCC etc.
pin1 for all jumpers are located on the side with a thick white line(pin1 .) refer to
the mainboard′s silkscreen , jumpers with three pins will be shown as to
represent pin1&pin2 connected and to represent pin2&pin3 connected.
2.2.1CMOS Content Clearance / Hold Setting（JCC）
Board contains a CMOS RAM, where the instored CMOS data is maintained by an
EMB-3682 AMD LX700, support VGA+LVDS or TTL

external battery. If you want to reset the CMOS data, first disconnect the power
supply (10V/220V) and set J1 to 1-2 closed for just a few seconds, then move the
jumper JCC back to the default status with pin2-3 closed and power on the system
again.
Setting state
1-2 Clear CMOS (retrieve the initial set)
2-3 Normal(default)
＊Do not clear CMOS when power on, otherwise the motherboard will be damaged
2.2.2 CF Card Function Master/Slave Selection（JCF）
The jumper is used for setting CF card’s slave or master disk. When JCF is closed，
CF card is Master device. When you remove jumper, it will be slave.

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.
Use boot disk to load DOS, run Afudos.exe to update the BIOS (eg. XXXX.ROM)
into the Flash IC.
Order format: A:\ Afudos XXXX.ROM
If you need to add other parameters after the order format, please add <space>/?
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
from our website
3. Please do not power off or reboot the system when upgrading, otherwise, the
BIOS maybe be damaged.
4. Please backup your BIOS before upgrading
3.2 AMI BIOS Description
When the computer is power on, BIOS will conduct self-diagnosis (POST)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.
3.3 BIOS Parameter Configuration
Power on your computer. After finishing the self-diagnosis, following message
will show on the screen:
Del->SETUP please press “DEL”, then it will enter BIOS setup interface.
1. Power on or Restart computer, self-detection information will show:

2. When message "Press <Del> to enter setup" shows up on screen, please press
<Del> to enter into BIOS configuration program..
3. Use the “←↑→↓”to choose the options that your want to modify, press <Enter>
and show the sub-menu.
4. Use the “←↑→↓”and <Enter> to modify the value of the options that you chosen
5. At any time, press<Esc> can back to the father-menu.

Appendix 1: Glossary
ACPI
Advanced Configuration and Power Management Interface for short. ACPI
specifications allow OS to control most power of computer and its extended devices.
Windows 98/98SE, Windows 2000 and Windows ME are all support ACPI, it provide
users a flexible system power management.
ATX:
AT extended, a motherboard layout complied with modern standard
motherboard layout replacing Baby AT. It changes disposal of many components,
and do some new high efficiency design, so it is widely used now.
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 channels 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
EMB-3862 AMD LX700, support VGA+LVDS or TTL
49
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.
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
IDE
Driver specifications for integrated circuit devices, It is widely used for
connecting HDD / CD-ROM devices.
IRDA
Infrared Data Association for short. Here it refers to infrared transmit interface,
to connect infrared transmit devices. This sort of device transmits data by infrared
light-wave without connecting any cables .It has been developed into a standard
now.
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.
LPT
Line print terminal, the denomination reserved by DOS, is an universal parallel
interface usually used to connect printer.
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, 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 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 on.
