Chapter 1 Introduction
Welcome to the most powerful Intel 815E based single board computer.
The CPU board combines the high performance and exceptional value of Intel Celeron / Pentium III CPU
and 815E chipset with a full-featured, new generation, full-size single board computer. The Intel 815E
chipset, which combining internal graphics, LAN, and support for 4 USB ports, Ultra DMA66/100 IDE
interface, that meets the performance, stability and reliability requirements. Moreover, In order to meet the
network requirement, the CPU boards add one more Ethernet Controller Intel 82559 to support dual channel
Ethernet.
For the Display solution, not only the Intel 82815 (GMCH) chipset integrated Graphics controller, the CPU
board also provide On Board Optional ATI Rage Mobility M4 3D VGA accelerator with on die 8MB or 16MB
memory to support 4X AGP, which is compatible with DVI specification to support LCD panel.
The Intel 82815 (GMCH) chipset integrated Graphics with Intel Dynamic Video Memory Technology, the
D.V.M.T. employs direct AGP and intelligent arbitration to dynamically allocate and de-allocate memory for
textures for applications requiring additional texture memory. The operating system requires allocation of up
to 1MB of system memory to support legacy VGA. System properties will display up to 1MB less than
physical system memory available to the operating system. The graphics driver for the Intel 815
configuration will request up to 4MB of memory from the OS to implement a maximum 1024x768 screen
resolution, 2MB for a command buffer and 4MB used for Z-buffering. For high-end 3D applications, the
drivers request allocation of system memory from the O/S for AGP graphics textures. When the 3D
application is closed, the O/S will re-allocate system memory back for generic use.
The board is suitable and valuable for all the embedded applications, which also well support with the
Windows 2000, Windows NT and Linux Operation system.

Chapter 3 Capability Expanding
This chapter explains how you can expand capability of your CPU board in such aspects as system memory
and CPU.
3-1 System Memory
The CPU board supports 2 slots for 168-pin 3.3V Non-registered DIMM modules, providing support for up to
512MB of main memory using DIMM modules from 8MB to 256MB. The following is the example to install
the system SDRAM memory module combination.
Note:
1. It is highly recommended to use the PC-100 or PC-133 Specification DIMM module.
2. Due to limitation of Intel 815E chipset, the board can’t support the ECC memory module.
Q’ty of Module DIMM1 DIMM2 Module Size Max. Size
1 1 st 8~256 MB 256 MB
2 1 st 2 nd 8~256 MB 512 MB
To insert the DIMMs, the modules must be oriented in
the correct way. Notice the notches of the DIMM.
Align these notches as shown in the diagram below.
Gently push the DIMM until the retainers on both
sides of the socket lock the module in place.
To remove a DIMM, push the retainers outwards to
release the module then pull the module out of the
socket.

3-2 Change CPU
To change the CPU, pull the handling bar of the socket upward to the other end to loosen the socket's
openings. Carefully lift the existing CPU up to remove it from the socket.
Removing CPU
Place the new CPU on the middle of the socket, orienting its beveled corner to line up with the socket's
beveled corner. Make sure the pins of the CPU fit evenly to the socket openings. Replace the handling
bar to fasten the CPU to the socket. Be sure to re-arrange the jumper setting for the correct external clock.

BIOS Setup 4-1
Chapter 4 AWARD BIOS Setup
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 RAM (CMOS RAM) so that it retains the Setup
information when the power is turned off.
4-1 BIOS Setup
Entering Setup
Power on the computer and press <Del> immediately will allow you to enter Setup. The other way to
enter Setup is to power on the computer, when the below message appears briefly at the bottom of the
screen during the POST (Power On Self Test), press <Del> key or simultaneously press <Ctrl>, <Alt>,
and <Esc> keys.
TO ENTER SETUP BEFORE BOOT
PRESS <CTRL-ALT-ESC> OR <DEL> KEY
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" button on the system case. You may also
restart by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at the
correct time and the system does not boot, an error message will be displayed and you will again be
asked to,
