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 SBC84621 Series is a Capa board with support for AMD

®

LX800

CPU at FSB 500 MHz (optional LX700 433 MHz) that features graphics, Fast Ethernet and audio interface. The board can be adapted to AMD

®

processors with its designing for space-limited applications, and a standard format conforming to the size of a 3.5”

Hard Disk drive. To simplify the system integration, super I/Os, LVDS,

Ethernet and solid state disk are provided to make all on one single borad. Four serial ports (3 x RS-232, 1 x RS-232/422/485) with

+5V/12V power capability make a unique embedded feature to apply an extensive array of PC peripherals. The industrial-grade construction of SBC84621 Series allows your system to endure the continuous operation in hostile environments where most require stability and reliability. The system dependability of SBC84621 Series can be enhanced by its built-in watchdog timer, a special industrial feature not commonly seen on other motherboards.

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.

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:

4.14 Set Supervisor/User Password

You can set a supervisor or user password, or both of them. The differences between them are:

1.

2.

Supervisor password: You can enter and change the options on the setup menu.

User password: You can just enter, but have no right to change the options on the setup menu.

When you select this function, the following message will appear at the center of the screen to assist you in creating a password.

ENTER PASSWORD

Type a maximum eight-character password, and press <Enter>. This typed password will clear previously entered password from the CMOS memory. You will be asked to confirm this password. Type this password again and press <Enter>. You may also press <Esc> to abort this selection and not enter a password.

To disable the password, just press <Enter> when you are prompted to enter a password. A message will confirm the password is getting disabled. Once the password is disabled, the system will boot and you can enter Setup freely.

PASSWORD DISABLED

When a password is enabled, you have to type it every time you enter the Setup. It prevents any unauthorized persons from changing your system configuration.

Additionally, when a password is enabled, you can also require the

BIOS to request a password every time the system reboots. This would prevent unauthorized use of your computer.

You decide when the password is required for the BIOS Features Setup

Menu and its Security option. If the Security option is set to “System”, the password is required during booting up and entry into the Setup; if it is set as “Setup”, a prompt will only appear before entering the Setup.
