CPU Speed Selection
In this motherboard, jumperless feature is implemented such that no jumper is required to
be set for different type of CPU installed.
Notice:
1. Be sure to save the CMOS setting when exit the CMOS.
2. Celeron PGA370 CPU is frequency multiplier locked, no CPU speed change will
be seen even if the frequency multiplier setting in CMOS setup is changed.

Warning:
Before handling the motherboard from its original package, please
ensure that there is no static electricity on your body. Otherwise it
may cause damage to the integrated circuits on the motherboard.

Memory Configuration
You can install up to 768MB SDRAM of memory in the motherboard DIMM
sockets. The board has DIMM sockets arranged as banks 0, 1, and 2. You can
installDIMMs in anyof the threebanks, and usedifferent size DIMMs in different
banks. The BIOS detects the size and type of installed memory.
To Install DIMMs
1. Turnoff allperipheral devicesconnectedto thecomputer.Turnoffthe computer.
2. Remove the computer cover and locate the DIMM sockets.
3. Holding the DIMM by the edges, remove it from its antistatic package.
4. Make sure the clips at either end of the socket are pushed away from the
socket.
5. Position the DIMM above the socket. Align the two small notches in the
bottom edge of the DIMM with the keys in the socket.
6. Insert the bottom edge of the DIMM into the socket.
7. When the DIMM is seated, push down on the top edge of the DIMM until the
retaining clips at the ends of the socket snap into place. Make sure the
clips are firmly in place.
8. Replace the computer cover.
9. If you installed a DIMM with ECC memory, start the computer and use the
ECC Configuration feature in Setup to enable the use of ECC.

Hardware Setup
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.

BIOSSETUP
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 thescreen. The Main Menuallows you toselect from varioussetup functions
and two exit choices. Use the arrow keys to select among the items and press
<Enter> to accept and enter the sub-menu.
