Section 5. Installation and Setup
In this section, you will learn how to install the CPU, DDR
Module, and also how to set up jumpers and all the information
about the components on the motherboard. Not only can you find
the installation steps, but also the details and locations of the
components on the motherboard.
1. CPU Installation1. CPU Installation
1. CPU Installation1. CPU Installation
1. CPU Installation
The motherboard supports the AMD Athlon 64®Socket-754 processor. When
you are installing the CPU, make sure the CPU has a cooling fan attached on the right
to prevent overheating. If you do not find the cooling fan, contact your dealer and make
sure to install them before turning on the computer.
Step1: Pull the lever sideways away from the socket and then raise the
lever up to a 90-degree angle.
Step2: Look for the white dot/cut edge. The white dot/cut edge should
point towards the lever pivot. The CPU will fit only in the cor-
rect orientation.
Step3: Hold the CPU down firmly, and then close the lever.
Step4: Put the CPU fan on the CPU and buckle it. Connect the CPU fan
power cable to the JCFAN1. This completes the installation.

These fan headers support cooling fans built in the computer. Orient the fans to
make the heat sink fins to allow air flow to go across the onboard heat sinks instead of
the expansion slots. The fan wiring and plug may be different according to the fan
manufacturer. Connect the fan fable to the connector while matching the black wire to
the ground pin.

the wireless LAN card with its com-
ponents towards the inner part of the
motherboard.
2. Insert the wireless LAN card verti-
cally and firmly into the slot till the

on pins, the jumper is “close”. IF no jumper cap is placed on the pins, the jumper is
”open”. The illustration shows a 3-pin jumper whose pin1and 2 are “close” when

(1) Floppy Disk Connector: FDD1
The motherboard provides a standard floppy disk connector that supports
360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types. This connector
supports the provided floppy drive ribbon cables.
(2) Hard Disk Connectors: IDE1/ IDE2
The motherboard has a 32-bit Enhanced PCI IDE Controller that provides PIO
Mode 0~4, Bus Master, and Ultra DMA 33/ 66/ 100/ 133 functionality. It has
two HDD connectors IDE1 (primary) and IDE2 (secondary).
The IDE connectors can connect a master and a slave drive, so you can connect
up to four hard disk drives. The first hard drive should always be connected to
IDE1.
(3) Peripheral Component Interconnect Slots: PCI1-5
This motherboard is equipped with 5 standard PCI slots. PCI stands for Pe-
ripheral Component Interconnect, and it is a bus standard for expansion cards.
This PCI slot is designed as 32 bits.
(4) Accelerated Graphics Port Slot: AGP1
Your monitor will attach directly to that video card. This motherboard sup-
ports video cards for PCI slots, but it is also equipped with an Accelerated
Graphics Port (AGP). An AGP card will take advantage of AGP technology to
improve video efficiency and performance, especially with 3D graphics.
(5) Communication Network Riser Slot: CNR1
The CNR specification is an open Industry Standard Architecture, and it de-
fines a hardware scalable riser card interface, which supports modem only.

(7) IDE-Raid Connector: RAID1/2 (optional)
This connector supports RAID0 or RAID1 or RAID 0+1 configuration through
the onboard Parallel ATA (VT6410) controller chip. You can use the IDE
feature to set up a disk array configuration and to support additional IDE
devices. However, it can only support master mode IDE HDD.
(8) Clear CMOS Jumper: JCMOS1
This jumper helps you to clear the Real Time Clock (RTC) Ram in CMOS. You
can erase the CMOS RTC Ram data to clear the CMOS memory of date, time,
and system setup parameters.
JCMOS1 Assignment
Pin 1-2 Close Normal Operation (default)
Pin 2-3 Close Clear CMOS Data
* Clear CMOS Procedures:
1. Remove AC power line.
2. Set the jumper to "Pin 2-3 Close".
3. Wait for five seconds.
4. Set the jumper to "Pin 1-2 Close".
5. Power on the AC.
6. Reset your desired password or clear the CMOS data.
(9) Front USB Header: JUSB1/ (JUSB2: optional)
The motherboard provides two USB 2.0 Pin Header. USB 2.0 technology
increases Data transfer rate up to a maximum throughput of 480 Mbps, which
is 40 times faster than USB 1.1, and is ideal for connecting high-speed USB
interface peripherals such as USB HDD, digital cameras, MP3 players, printers,
modems, etc.
