BE SURE YOU KNOW WHA T YOU ARE DOING!
•It’s easy to get overly excited about your purchase, and to jump right into installing the
system board into your case. T oo many times, people fail to read the manual or insist on
installing it themselves, only to find out later that they’ve permanently damaged their
motherboard and as well as their components. Though this manual will make installation
seem like a fairly simple procedure, it is not. So, if you’re not a technophile or have little
or no computer knowledge, consider asking your vendor or a trained technician to install
this board.
SETUP THE CPU RETENTION CLIP(S)
•Look at the CPU installation page for instructions on setting up the retention clips.
INSERT THE CPU INTO THE SOCKET

Award’s BIOS ROM has a built-in Setup program that allows users to modify the basic
system configuration. This type of information is stored in battery-backed CMOS SRAM
so that it retains the Setup information when the power is turned off.
WARNING
•Due to the frequent upgrades of the AWARD BIOS, this manual may not include
descriptions of all the features available to you in your current BIOS.
•Do not change the settings in the BIOS unless you know EXACTLY what you are doing
or when told to do so by a trained technician. Changing any of the BIOS settings, may
affect the performance of your system and can also cause your system to hang.
ENTERING THE BIOS SETUP
•Power ON the computer and press <Del> immediately will allow you to enter Setup. If the
message disappears before you respond and you still wish to enter Setup, restart the
system to try again by turning it OFF then ON or pressing the “RESET” bottom on the
system case. You may also restart by simultaneously press <Ctrl>, <Alt>, and <Del>
keys.

The system bus speed can be set to 66.6MHz or 100MHz from the jumper (JP6). The
user can change the DIP SWITCH (SW) selection to set up the CPU speed for different
processors. The CPU speed must match with the frequency RATIO and Front Side Bus

This motherboard supports an Intel Pentium II processor using a Single Edge Contact
(SEC) slot. Make sure that you have the following items (which should be included in the
package) before doing any installation: (1) 4 screws (2) 1 retention clip.
(1) There are 2 sets of small holes along Slot 1 of your
motherboard: two on the top and two on the bottom. Snap the
retention clip (2) right into those 2 sets of holes. If the retention
clip is installed incorrectly, you will not be able to insert the CPU
into the retention clip.

MEMORY CONSIDERATIONS
•The mainboard lets you add up to 768MB of system memory through 3 DIMM
sockets on the board
•The three 168-pin DIMM sockets are divided into three banks: BANK 0, 1 & 2.
•The speed of all DIMM modules must be 67 - 100 MHz for SDRAM when system bus
speed is set to 66MHz
•When system bus speed is set to 100MHz, 100MHz SDRAM is required.
•When installing DIMM modules, make sure that Pin 1 of the module must match with Pin
1 of the DIMM socket. Press down firmly until the side clips lock into place.
(2) Find the holes in each corner of the retention clip and insert
one of the four screws into each of these holes.
(3) Push the screws downward to secure the retention
clip.
(4) Flatten the two latches on the side of the CPU. Insert
CPU INSTALLATION
the CPU into the retention clip. Lock the two latches to
secure the CPU.
