Hardware Setup
Memory
The mainboard provides 2 slots for 184-pin, 2.5V DDR DIMM with 4
memory banks. You can install DDR266/PC2100 or DDR333/PC2700 DRAM
modules on the DDR DIMM slots (DDR 1~2). The supported maximun memory
size is 2GB. To operate properly, at least one DIMM module must be installed.
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod-
ules rather than 168-pin DIMM modules used by SDR SDRAM. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta-
tions and servers.

DDR Module Combination
Install at least one DIMM module on the slot. Memory modules can be
installed on the slots in any order. You can install either single- or double-sided
modules to meet your own needs.
Memory modules can be installed in any combination as follows:

Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The module
will only fit in the right orientation.
2. Insert the DIMM memory module vertically into the DIMM slot. Then
push it in until the golden finger on the memory module is deeply inserted
in the socket.
TIP: You can barely see the golden finger if the module is properly
inserted in the socket.
3. The plastic clip at each side of the DIMM slot will automatically close.

Jumpers
The motherboard provides one jumper for you to set the computer’s
function. This section will explain how to change your motherboard’s function
through the use of the jumper.
Clear CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power supply from external
battery to keep the data of system configuration. With the CMOS RAM, the
system can automatically boot OS every time it is turned on. That battery has
long life time for at least 5 years. If you want to clear the system configuration,
use the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions
below to clear the data:

Slots
The motherboard provides three 32-bit Master PCI bus slots, one AGP
slot and one CNR slot.
AGP Slot
PCI Slots
CNR Slot
AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card. AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory. The slot supports 2x/4x AGP card.
PCI Slots
Three PCI slots allow you to insert the expansion cards to meet your
needs. When adding or removing expansion cards, make sure that you unplug
the power supply first. Meanwhile, read the documentation for the expansion
card to make any necessary hardware or software settings for the expansion
card, such as jumpers, switches or BIOS configuration.
CNR (Communication Network Riser)
The CNR slot allows you to insert the CNR expansion cards. CNR is a
specially designed audio, or modem riser card for ATX family motherboards.
Its main processing is done through software and controlled by the
motherboard’s chipset.

SpreadSpectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec-
trum function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves. If you do not have any EMI
problem, leave the setting at Disabled for optimal system stability and
performance. But if you are plagued by EMI, setting to Enabled for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking be-
cause even a slight jitter can introduce a temporary boost in clockspeed which
may just cause your overclocked processor to lock up.

BIOS (basic input/output system)
On PCs, an essential software that contains all the control code of input/output inter-
face (such as keyboard, disk drives, etc.). It executes hardware test on booting the
system, starts the OS, and provides an interface between the OS and the components.
The BIOS is stored in a ROM chip.
Bus
A set of hardware lines within the computer system, through which the data is trans-
ferred among different components. In a PC, the term bus usually refers to a local bus
that connects the internal components to the CPU and main memory.
Cache
A special memory subsystem that is used to speed up the data transfer. It stores the
contents of frequently accessed RAM locations and the addresses where these data
items are stored.
Chipset
A collection of integrated chips designed to perform one or more related functions. For

example, a modem chipset contains all the primary circuits for transmitting and receiv-
ing data; a PC chipset provides the electronic interfaces between all subsystems.
CMOS (complementary metal-oxide semiconductor)
CMOS is a widely used type of semiconductor, which features high speed and low
power consumption. PCs usually contain a small amount of battery-powered CMOS
memory to retain the date, time, and system setup parameters.
COM
In MS-DOS system, the name of a serial communications port. DOS supports four
serial ports. For example, if a modem is connected to one serial port and a serial mouse
to another, they are identified as COM1 and COM2.
DIMM (dual in-line memory module)
A small circuit board that holds memory chips. A SIMM (single in-line memory
module) has a 32-bit path to the memory chips whereas a DIMM has 64-bit path.
DRAM (Dynamic RAM)
A most common type of computer memory. It usually uses one transistor and a
capacitor to represent a bit. As the development of technology, the memory type and
specification used in computer becomes variety, such as SDRAM, DDR SDRAM, and
RDRAM. For further instruction, please see the table below:

ECC Memory (error correcting code memory)
A type of memory that contains special circuitry for testing the accuracy of data and
correcting the errors on the fly.
IDE (Integrated Drive Electronics)
A type of disk-drive interface widely used to connect hard disks, CD-ROMs and tape
drives to a PC, in which the controller electronics is integrated into the drive itself,
eliminating the need for a separate adapter card. The IDE interface is known as the
ATA (AT Attachment) specification.
IEEE1394
A new, high speed external bus standard, also known as FireWire or iLink, which
supports data transfer rates of up to 400 Mbps for connecting up to 63 external
devices.
IrDA (Infrared Data Association)
A group of device vendors, including computer, component and telecommunications,
who have developed a standard for transmitting data via infrared light waves. This
enables you to transfer data from one device to another without any cables.
LAN (local area network)
A computer network that covers a relatively smaller area, such as in a building or an
enterprise. It is made up of servers, workstations, shared resources, a network oper-
ating system and a communications link. These individual PCs and devices on a LAN
are known as “nodes”, and are connected by cables to access data and devices any-
where on the LAN, so that many users can share expensive devices and data.
LED (light emitting diode)
A semiconductor device that converts electrical energy into light. Since it lights up
(usually red) when electricity is passed through it, it is usually used for the activity
lights on computer’s component, such as disk drivers.
LPT (line printer terminal)
Logical device name for a line printer; a name reserved by the MS-DOS for up to three
parallel printer ports: LPT1, LPT2, and LPT3. It is frequently used by the OS to
identify a printer.

PCI (Peripheral Component Interconnect)
A local bus standard developed by Intel that first appeared on PCs in late 1993. PCI
provides “plug and play” capability and allows IRQs to be shared. The PCI controller
can exchange data with the system's CPU either 32 bits or 64 bits at a time.
PnP (Plug and Play)
A set of specifications that allows a PC to configure itself automatically to work with
peripherals. The user can "plug" in a peripheral device and "play" it without configur-
ing the system manually. To implement this useful feature, both the BIOS that sup-
ports PnP and a PnP expansion card are required.
POST (Power On Self Test)
During booting up your system, the BIOS executes a series of diagnostic tests, include
checking the RAM, the keyboard, the disk drives, etc., to see if they are properly
connected and operating.
PS/2 Port
A type of port developed by IBM for connecting a mouse or keyboard to a PC. The
PS/2 port supports a mini DIN plug containing just 6 pins. Most modern PCs equipped
with PS/2 ports so that the special port can be used by another device, such as a
modem.
USB (universal serial bus)
A hardware interface for low-speed peripherals such as the keyboard, mouse, joystick,
etc. USB provides a maximum bandwidth of 12 Mbit/sec (Mbps) for connecting up to
127 peripheral devices to PC. USB features hot swap capability and multiple data
streams, allows external devices to be plugged in and unplugged without turning the
system off.
Virus
A program or a piece of code that infects computer files by inserting in those files
copies of itself. The virus code is buried within an existing program, and is activated
when that program is executed. All the viruses are man-made, and often have damaging
side effects.
