Installing the Processor
For easy installation of the CPU, it is recommended that you remove all
Cards in PCI slots first.
• Unpack the CPU and identify the pin 1 corner of the CPU.
• Match pin 1 of the CPU with pin 1 of the CPU socket. The pin 1 corner of
the CPU socket is designated by a small triangle printed on the
motherboard.
• Carefully insert the CPU into the CPU socket and move the metal arm
downward to replace it in its original position. Change any jumper
settings as detailed in the manual.
The small circle marked on the top of the CPU designates the pin 1 corner.
If a heat sink is attached and covers the top of the CPU, identify the pin 1
corner by turning the CPU over. Locate the small gold finger that extends
from one corner of the large central square portion of the CPU. The gold
finger points towards pin 1, which is also uniquely identified by a square pad.
Positioning the CPU incorrectly in the socket can permanently damage
the CPU and the computer when you turn on the system.
Warning:
There is a fan attached the CPU to prevent the overheating, please
ensure that the fan can operate. Otherwise the CPU can overheat
and cause damage to both CPU and motherboard.

BIOS SETUP
This chapter discusses Award’s Setup Program built into the ROM BIOS. The
Setup Program allows users to modify the basic system configuration. This
special information is then stored in battery-backed RAM, which retains the
setup information when the power is turned off.
Starting Setup
The Award BIOS is immediately activated when you turn on the computer. The
BIOS reads the system information contained in the CMOS and begins the
process of checking out the system and configuring it. When it finishes, the
BIOS will seek an operating system on one of the disks and then launch and
turn control over to the operating system .
While the BIOS is in control, the Setup Program can be activated :
1. By pressing <Del> immediately after switching the system on, or
2. By pressing the <Del> key when the following message appears briefly at
the bottom of the screen during the POST (Power On Self Test )
Press DEL to enter SETUP
If the message disappears before you can respond and you still wish to enter
Setup, restart the system to try again by turning it OFF then ON or pressing the
“RESET” button on the system case. You may also restart by simultaneously
pressing the <Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at
the correct time and the system does not reset, an error message will be
displayed and you will again be asked to ...
PRESS F1 TO CONTINUE, DEL TO ENTER SETUP
Getting Help
Press F1 to pop up a small help window that describes the appropriate keys to
use and the possible selections for the highlighted item. To exit the Help
Window press <Esc> or the F1 key again.
In Case of Problems
If, after making and saving system changes with the Setup Program, you
discover that your computer does not reset, use the Award BIOS defaults to
override the CMOS settings.
Main Menu
Once you enter the Award BIOS CMOS Setup Utility , the Main Menu will appear
on the screen. The Main Menu allows you to select from various setup functions
and two exit choices. Use the arrow keys to select among the items and press
<Enter> to accept and enter the sub-menu.

password. A message will be displayed to confirm that the password is
disabled.
PASSWORD DISABLED.
Once the password is disabled, the system will reset and you can enter the
Setup Program freely.
When a password is enabled, you will be prompted to enter it every time you
try to enter setup. This prevents an unauthorized person from changing any
setting of your system configuration.
In addition, when a password is enabled, you can require the BIOS to request
a password every time your system is rebooted. This would further prevent
unauthorized use of your computer.
The password requirement is defined by the Security Option of the BIOS
Features Setup Menu. If the Security Option is set to “System”, the password
will be required both at resetting and at entering setup. If the option is set to
“Setup”, the prompt only appears when you try to enter setup.
