ESD Precautions
Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

Introduction
The EP820 Series is an Intel
equipped EP820 board with graphics, Fast Ethernet and audio
interface. With the designing of space-limited application, the EP820
Series makes the finest embedded Pentium
using a newly standardized EPIC format, larger than a PC/104
module, yet smaller than an EBX board.
EP820 Series can be adapted for Intel
Pentium
provides users with super I/Os, XVGA, LCD, Ethernet and solid state
disk that makes all on one single board. There comes with the unique
embedded feature that two serial ports (1 x RS-232, 1 x RS232/422/485) with +5V/12V power capability allow the adoption of an
extensive array of PC peripherals. The industrial-grade construction of
EP820 Series allows your system to endure the continuous operation
in hostile environments where require most stability and reliability.
The system dependability of EP820 series is highly enhanced by a
special industrial feature of the built-in Watchdog Timer, which makes
the board outstanding among others.

+, and Pin 5 as -. The Power LED lights up when the system is
powered ON.
External Speaker and Internal Buzzer Connector
Pin 2, 4, 6 and 8 can be connected to the case-mounted speaker unit
or internal buzzer. While connecting the CPU card to an internal buzzer,
please short pins 2-4; while connecting to an external speaker, you
need to set pins 2-4 to Open and connect the speaker cable to pin 8 (+)
and pin 2 (-).
ATX Power On/Off Button
This 2-pin connector named as Pin 9 and 10 connect the front panel’s
ATX power button to the CPU card, which allows users to control ATX
power supply to be power on/off.
System Reset Switch
Pin 11 and 12 can be connected to the case-mounted reset switch that
reboots your computer, not turns OFF the power switch. It is a better
way to reboot your system for a longer life of the system’s power
supply.

Award BIOS Utility
The Phoenix-Award BIOS provides users with a built-in Setup program
to modify basic system configuration. All configured parameters are
stored in a battery-backed-up RAM (CMOS RAM) to save the Setup
information whenever the power is turned off.
4.1 Entering Setup
There are two ways to enter the Setup program. You may either turn
ON the computer and press <Del> immediately, or press the <Del>
and/or <Ctrl>, <Alt>, and <Esc> keys simultaneously when the
following message appears at the bottom of the screen during POST
(Power on Self Test).
TO ENTER SETUP PRESS DEL KEY
If the message disappears before you respond and you still want to
enter Setup, please restart the system to try it again. Turning the
system power OFF and ON, pressing the “RESET” button on the
system case or simultaneously pressing <Ctrl>, <Alt>, and <Del> keys
can restart the system. If you do not press keys at the right time and
the system doesn’t boot, an error message will pop out to prompt you
the following information:

Award BIOS Utility
Page 61
EP820 All-In-One EPIC Board User’s Manual
This item specifies the power saving modes for ACPI function. If
your operating system supports ACPI, such as Windows 98SE,
Windows ME and Windows 2000, you can choose to enter the
Standby mode in S1 (POS) or S3 (STR) fashion through the setting
of this field. Options are:
[S1 (POS)] The S1 sleep mode is a low power state. In this
state, no system context is lost (CPU or chipset) and
hardware maintains all system contexts.
[S3 (STR)] The S3 sleep mode is a lower power state where
the information of system configuration and open
applications/files is saved to main memory that remains
powered while most other hardware components turn off to
save energy. The information stored in memory will be used
to restore the system when a “wake up” event occurs.
z Power Management
This option allows you to select the type (or degree) of power
saving for Doze, Standby, and Suspend modes. The table below
describes each power management mode:
Max Saving

It is maximum power savings, only available for SL CPUs.
The inactivity period is 1 minute in each mode.
It sets each mode. Select time-out periods in the PM

It is minimum power savings. The inactivity period is 1
hour in each mode (except the hard drive).

z PM Control by APM
If Advanced Power Management (APM) is installed in your system,
the selection of Yes will give better power savings. The default
value is “Yes”.
No
Yes
System BIOS will ignore APM when power is managing the

The System BIOS will wait for APM’s prompt before it enters
any PM mode (i.e., DOZE, STANDBY or SUSPEND).
Note: If APM is installed or there is a task running, even when
the timer has timed out, the APM will not prompt the BIOS to
put the system into any power saving mode
