User friendly instructions
Our objective is to enable the novice computer user to perform the
installation by themselves. We have attempted to write this document in
a very clear, concise and descriptive manner to help overcome any obstacles
you may face during installation. Please read our instructions carefully
and follow them step-by-step.
Installing the Motherboard 2-3
(1)
Installing the Motherboard to the Casing
Most computer cases will have a base on which there will be many mounting
holes that allows the motherboard to be securely attached and at the same time,
prevents short circuits.
There are two ways to attach the motherboard to the base.
l with spacers
l or with bolts
In principle, the best way to attach the motherboard is with bolts, and only if
you are unable to do this should you attach the board with spacers. Take a
careful look at the motherboard and you will see many mounting holes on it.
Line these holes up with the mounting holes on the base. If the holes line up, and
there are screw holes this means you can attach the motherboard with bolts. If
the holes line up and there are only slots, this means you can only attach the
motherboard with spacers. Take the tip of the spacers and insert it into the slots.
After doing this to all the slots, you can slide the motherboard into position
aligned with the slots. After the motherboard has been positioned, check to
make sure everything is OK before putting the casing back on.
Note: If the motherboard has mounting holes, but don’t line up with the
holes on the base and their are no slots to attach the spacers, don’t
worry , you can still attach the spacers to the mounting holes. Just cut
the spacers (along the dotted line) (the spacer may be a little hard so
be careful of our hands). In this way you can still attach the
motherboard to the base without worrying about short circuits.

Introduction of BIOS
3-1
Chapter 3 Introduction of BIOS
The BIOS is a program located on a Flash Memory chip on the
motherboard. This program will not be lost when you turn the computer off.
This program is also referred to as the boot program. It is the only channel for
the hardware circuit to communicate with the operating system. Its main
function is to manage the setup of the motherboard and interface cards
parameters, including simple parameters such as time, date, hard disk drive, as
well as more complex parameters such as hardware synchronization, device
operating mode. The computer will operate normally, or will operate at its best,
only if all these parameters are correctly configured through the BIOS.
Don’t change the parameters inside the BIOS unless you know what
!!!!
you are doing
The parameters inside the BIOS are used to setup the hardware
synchronization or the device operating mode. If the parameters are not
correct, they will produce errors, the computer will crash, and sometimes you
will even not be able to boot the computer after it has crashed. We
recommend that you do not change the parameters inside the BIOS unless you
are familiar with them. If you are not able to boot your computer anymore,
please refer to the section “Erase CMOS data” in Chapter 2.
When you start the computer, it is controlled by the BIOS program. The
BIOS first operates an auto-diagnostic for all the necessary hardware,
configures the parameters of the hardware synchronization, and detects all the
hardware. Only when these tasks are completed does it give up control of the
computer to the program of the next level, which is the operating system.
Since the BIOS is the only channel for hardware and software to communicate,
it will be the key factor for system stability, and to ensure that your system
performs at its best. After the BIOS has achieved the auto-diagnostic and autodetection operations, it will display the following message:
PRESS DEL TO ENTER SETUP
Three to five seconds after the message is displayed, if you press the
key, you will access the BIOS Setup menu. At that moment, the BIOS will
display the following message:

CMOS DATA
Maybe you have heard somebody saying that their CMOS
DATA was lost. What is the CMOS? Is it important? The
CMOS is the memory used to store the BIOS parameters that
you have configured. This memory is passive. You can read
its data, and you can also store data in it. But this memory
has to be powered by a battery, in order to avoid any loss of
its data when the computer is turned off. Since you may have
to change the CMOS battery when it is out of power and if
doing so, you will loose all CMOS data, therefore, we
recommend that you write down all the parameters of your
hardware, or to put a label with these parameters on your
hard disk.
