Safety Precautions
Read and follow the content of the Safety Precautions carefully so that you
will not cause damages to yourself or the system.
1. Pay attention to the warnings and notes in this manual to avoid causing
unexpected damages.
2. If you want to wipe the system with a wet cloth, make sure the power
cord is disconnected. We strongly suggest not to wipe the system with
chemical detergent or sprayed detergent.
3. When moving the system, do not put the system on uneven, unsteady
or slanting surfaces.
4. Do not put water cups or beverages near the PC system to protect the
system from being damaged by liquids.
5. There are ventilating holes on the backboard of the computer case
to dissipate heat from the machine. You should pay attention to the
position of the PC so that the ventilating holes will not be blocked.
Meanwhile, don’t put your PC on something not sturdy enough – like
rug or bed mattress – to ensure smooth air ow for heat dissipation.
6. Before plugging on power, make certain the electric voltage in your
area complies with that of the PC. If you are uncertain, consult your PC
dealer or power company rst.
7. Do not place your PC on power cords. Do not leave the power lines in
tangles which may cause people to stumble.
8. It normally takes several power sockets to meet the need of a PC
system. Make sure the extension power line is capable of handling
the total power load for all equipment. In other words, the combined
amperage of all electrical appliances on the same extension line must
not exceed the strength of electric currents or the fuse of the extension
line.

1.5 Get Ready for Installation
Before building your PC, clear a good-size workspace. Open the
components pack. Follow these steps:
Step 1
Carefully select the workspace. Avoid places with heavy dusts, wet or
high temperature. Stay away from other electric equipment. Especially,
the electric source and connecting parts should have a distance from
other electrical appliances to avoid electromagnetic or wireless frequency
interference. This generally should not be a problem at home. But you
should pay special attention when building the PC in other places to stay
away from heating equipment, air conditioners, copy machines, TV sets,
and wireless broadcasting stations or antennas.
Step 2
Open the components pack and count all parts in the pack. Such information
is available at the front section of this manual and make sure all the listed
items are included. Carefully secure the pack because you will need the
pack to collect the items when you have to move the PC to a new place
in the future. In case there are items missing in the pack, contact your PC
dealer immediately to make up all components and accessories.
Step 3
Connecting parts and components: Connect all cables with respective
sockets and plug power cable into power source socket.
Caution: Make sure all wires and cables are connected before you connect
power cable and switch on power source.


Step 4
Turning on power: After completing the preceding steps, reafrm your PC
is connected correctly with peripheral lines for printer, monitor, speaker,
etc. Then you may press the power switch on the front panel of the PC to
activate the machine. Your computer should start operating.
Step 5
Shut down PC properly: When you want to turn off the computer, click the
“Start” button at the left bottom of the PC screen in the operating system
and then click “Shut Down”.
Because the system is delivered as a bare system, a user is offered the
choice to install the CPU, memory module, hard disc drive, or optical disc
drive. In order to install these optional devices, a user needs to know how to
disassemble the system unit. Before disassembling the system unit, a user
needs to get familiarized with the housing.


1.6 Disassemble the System
A user can disassemble the system according to the following steps.
1.6.1 Remove Top Cover
A user can disassemble the upper case by removing the three screws on the
three sides of the rear panel.
Remove the screws fastening the top cover to the back panel of the system
unit.
Pull out the top cover horizontally toward the direction of the front panel
until the rear edge of the top cover is 2 cm (0.787 inch) from the rear panel.
Then, lift the top cover.
Front Panel


Remove the link bar. The link bar is used to add extra stability to the
structure and the riser card.
Remove the two screws fastening the optical drive cage to the chassis.
Optical drive cage


Slide out the drive cage horizontally.
Tilt the front end of the drive cage slightly to release the optical cage from
the chassis.


If you turn the optical drive cage upside down, you will see two tenons,
which should be inserted into the mortises on top of the hard disk drive
cage when you replace the optical drive cage on top of the HDD drive cage.
1.6.2 Remove Hard Drive
The HDD drive cage is fastened to the chassis with one screw. Remove the
screw, and push the HDD drive cage toward the rear of the chassis until it is
detached from the chassis.


1.6.3 Install HDD Drive
Slide the hard drive into the drive cage and make sure you can drive screws
through the slots of the drive cage.
After the hard drive is xed with screws on its sides, replace the drive cage
into the chassis and x it to the chassis with a screw.
Connect the at ribbon cable and power cord to the hard drive.
Note: Before you install hard drive to the drive cage and chassis, make sure
the power supply has been installed.
1.6.4 Install Memory Module
If you have to install memory modules by yourself, you have to remove
the optical drive cage first because the on-board memory slots are only
accessible after the optical drive cage has been removed. The memory
module is built with a fool-proof notch. The notch makes sure that the
memory module will not be installed incorrectly. The notch should match
an extruding point of the memory socket. Press down the memory modules
into the slots and lock them onto the slots with the clasps on two sides of
the memory slots.


1.6.5 Remove and Install Power Supply
The power supply is fastened to the rear panel with ve screws. After the
ve screws are removed, you can lift it to disassemble it from the chassis.
When you restore it back to the chassis, you have to tilt the power supply
(the side with the fan) slightly toward the rear panel. This will make the
installation easier. Do not force the power supply into its rack.
1.6.6 Install CPU
Remove the CPU cooler from the printed circuit board (PCB) by taking out
the four screws xing the cooler to the PCB.
Remove the CPU plastic protective cap.


Release the steel wire lever of the CPU socket.
Open the metal cap covering the CPU socket. Install the CPU.
Note: You have to keep the CPU socket clean. Keep dust off from the CPU
socket. Before installing the CPU, you have to handle the CPU with care.
Do not touch the CPU pins with your ngers. There are two small extruding
points on two inner sides of the CPU socket, which should t with the two
dents on two sides of the CPU. The extruding points and dents are fool-
proof design which prevents wrong installation. After you have inserted the
CPU into the socket, press the L-shaped socket lever down and x it into
the clasp. The plastic CPU cover will come off. Save it at a safe place.

2. BIOS Installation
2.1 Turn On the Power
Introduction
In the system unit, there is an integrated circuit(IC), in which the basic
input/output system (BIOS) is stored. It is the built-in software that
determines what a computer can do without accessing programs from
a disk. On PCs, the BIOS contains all the code required to control the
keyboard, display screen, disk drivers, serial communications, and a
number of miscellaneous functions. The BIOS is typically placed in a ROM
chip that comes with the computer. The BIOS keeps a record of variables of
system parameters which can determine the functions of the computer.
System parameters can be modified by going into BIOS Setup menu;
this menu allows you to configure the system parameters and save the
conguration into the 128 bytes area (normally in the RTC chip or in the
main chipset).
The Phoenix-Award BIOS that installed in the flash ROM of the
motherboard is a custom version of an industry standard BIOS. The BIOS
provides critical fundamental support for standard input and output devices
such as hard disk drives, serial and parallel ports, optical devices, etc.
In most cases, you are not required to change the BIOS settings because our
R&D engineering team has been optimizing most BIOS settings to meet
the general requirements for the average users. Our BIOS is designed to
allow the experienced users changes a certain settings to meet their specic
requirements. This chapter is intended to explain how to change some
settings. To enter BIOS setup menu, press <Del> when POST( Power-On
Self Test) screen is shown on your video monitor.on your video monitor.
Note: Because BIOS code has been updated from time to time to meet
the latest customers’ requirement, the BIOS information contained in this

0
manual may look slightly different from the BIOS messages, which comes
with your system.
After you turn on the power, you will see the following screen. If you want
to enter BIOS setup menu, press <Del> when POST screen is shown on
your video monitor. If you would like to see the POST screen, you may
press <Tab> key.
Not long after activating the power, you'll see the following screen. Please
press Delete button to get into BIOS. If you would like to see the POST
screen, you may just press Tab button.
After pressing Delete, you'll see the following BIOS setup:
