before installation.
1. AW-A795 Low Power Embedded SBC
2. Quick Setup
3. Cable: Please refer to Appendix B Optional Cables
4. CD-ROM which contains the following folders:
(1) Manual
(2) System Driver
(3) Ethernet Driver
(4) Tools
If any of these items are missing or damaged, please contact your dealer from
whom you purchased the board at once. Save the shipping materials and
carton in the event that you want to ship or stor e the board in the future. After
you unpack the board, inspect it to assure an intact shipment. Do not apply
power to the board if it appears to have been damaged.
Leave the board in its original packing until you are ready to install
Precautions
Please make sure you properly ground yourself before handling the AW-A795 board or
other system components. Electrostatic discharge can be easily damage the AW-A795
board.
Do not remove the anti-static packing until you are ready to install the AW-A795 board.
Ground yourself before removing any system component from it protective anti-static
packaging. To ground yourself, grasp the expansion slot covers or other unpainted parts of
the computer chassis.
Handle the AW-A795 board by its edges and avoid touching its component.

2.2. Installing Processors
The A W -A795 onboard built-in socket 479 for Intel® Pentium® 4 Processors. After installing
the processor, you should proceed to installing the heatsink or cooler.
Before you install CPU please make sure the CPU is exactly Pentium 4 processor.
You can see the difference from CPU code and the pin out at backside.
(1) Pentium M CPU (Socket 479)
To Insert a DIMM Memory: Please align the module with the socket key and press down
until the levers at each end of the socket snap close up.
There is only one direction for installing a module in the socket. Do not attempt to force the
The ROM chip of your AW-A795 board is configured with a customized Basic Input/Output
System (BIOS) from Phoenix-Award BIOS. The BIOS is a set of permanently recorded
program routines that give the system its fundamental operational characteristics. It also
tests the computer and determines how the computer reacts to instructions that are part of
programs.
The BIOS is made up of code and programs that provide the device-level control for the
major I/O devices in the system. It contains a set of routines (called POST, for Power-On
Self Test) that check out the system when you turn it on. The BIOS also includes CMOS
Setup program, so no disk-based setup program is required CMOS RAM stores information
for:
Date and time
Memory capacity of the main board
Type of display adapter installed
Number and type of disk drives
The CMOS memory is maintained by battery installed on the AW-A795 board. By using
the battery, all memory in CMOS can be retained when the system power switch is turned
off. The system BIOS also supports easy way to reload the CMOS data when you replace
the battery of the battery power lose.
3.1 Quick Setup
In most cases, you can quickly configure the system by choosing the following main menu
options:
1. Choose “Load Optimized Defaults” from the main menu. This loads the setup default
values from the BIOS Features Setup and Chipset Features Setup screens.
2. Choose “Standard COS Features” from the main menu. This option lets you configure
the date and time, hard disk type, floppy disk drive type, primary display and more.
3. In the main menu, press F10 (“Save & Exit Setup”) to save your changes and reboot the
system.
Use the CMOS Setup program to modify the system parameters to reflect the options
installed in your system and to customized your system. For example, you should run the
Setup program after you:
Received an error code at startup
Install another disk drive
Use your system after not having used it for a long time
Find the original setup missing
Replace the battery
Change to a different type of CPU
Run the Phoenix-Award Flash program to update the system BIOS
Run the CMOS Setup program after you turn on the system. On-screen instructions
explain how to use the program.
Enter the CMOS Setup program’s main menu as follows:
1. Turn on or reboot the system. After the BIOS performs a series of diagnostic
checks, the following message appears:
“Press DEL to enter SETUP”
2. Preess the <DEL> key to enter CMOS Setup program. The main menu appears:

3. Choose a setup option with the arrow keys and press <Enter>. See the following
sections for a brief description of each setup option.
In the main menu, press F10 (“Save & Exit Setup) to save your changes and reboot the
system. Choosing “EXIT WITHOUT SAVING” ignores your changes and exits the
program. Pressing <ESC> anywhere in the program returns you to the main menu.
3.3 Menu Options
The main menu options of the CMOS Setup program are described in the following and the
following sections of this chapter.

SET SUPERVISORS & USER PASSWORD:
Configure the system so that a password is required when the system boots or you attempt
to enter the CMOS setup program. When you log in with this password, you will be able to
enter the COS Setup main menu, but you can not enter other menus in the CMOS Setup
program.
SAVE & EXIT SETUP:
Save changes of values to CMOS and exit the CMOS setup program
EXIT WITHOUT SAVING:
Abandon all CMOS changes and exit the CMOS setup program

The AW-A795 is a fully PC compatible control board, it consists of 16 ISA interrupt request
lines and most of them already in used by other part of the board. Please make sure that
the IRQs do not conflict if you would like to use extra add-on cards.
System IRQs are available to cards installed in the ISA expansion Bus first. Any
remaining IRQs then may be assigned to this PCI Bus. You are able to use the Microsof t’ s
