ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic
discharge, observe the following precautions:
!Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
!Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.
!Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

Installation
This chapter describes the procedures for installing the
SBC8232V all-in-one CPU card into your system.
The following is a list of typical peripherals required to build a
minimum system:
!Power supply and passive backplane (optional)
!IBM PC/AT keyboard
!Display monitor
!Floppy or hard disk with MS-DOS or Flash Disk
emulator
3.1 Installing SIMMs
You can install from 1MB up to 32MB memory onboard using 1,
4 or 16MB 72-pin single-side fast-page or EDO SIMMs.
1. Ensure that all power supplies to the system are
switched Off.
2. Insert the first SIMM edge connector at a slight
angle into the socket of SIMM 1 close to the center
of the board. Note that the SIMMs are keyed and
will only go in one way.
3. Push the SIMM back into the connector carefully
until it snaps into place.
4. Check to make sure the SIMM is inserted securely.
5. Repeat Steps 2-4 for remaining SIMM in SIMM 2. Or,
you can install one SIMM only on the board.

3.2 Completing the Installation
To complete the installation, the following steps should be
followed:
1. Make sure the power is off.
2. Set the configuration jumpers in accordance with
Chapter 2.
3. Install the SBC8232V CPU card into one of the slots
in a passive backplane. Or, just take the SBC8232V
alone as a single board computer.
4. Connect the applicable I/O cables and peripherals,
i.e. floppy disk, hard disk, monitor, keyboard,
power supply and etc.
NOTE: The color of pin one is usually red or blue, while
others are gray.
5. Turn on the power.

AMI BIOS Setup
4.1 System Initialization and Setup
Verification
After turning the power on, the system will run routine testing
and initialize board hardware. If there is any error during the
tests, you will either hear a few short beeps or see an error
message on the screen. The errors can either be fatal or non-
fatal. The system usually continues the boot up sequence with
not-fatal errors. Non-fatal error messages usually appear on
the screen along with the following instructions:
press <F1> to RESUME
Write down the message and press the F1 key to continue the
bootup sequence.
The current systems configuration is different from the values
stored in the boards CMOS memory. If they dont match, the
program will produce error messages. Youll have to run the
BIOS setup program again to set the correct configurations into
memory.
You will need to change the CMOS settings in following three
situations:
"during initial boot up of system,
"after adding and/or removing hardware attached to your
system,
"when CMOS memory loses information on the saved
configuration.
The SBC8232Vs CMOS memory has an integrated lithium
battery backup. The battery backup can last for ten years.
Once it runs down, you will need to replace the RTC parts.
Contact your system administrators for assistance.

4.2 AMI BIOS Initial Setup
AMIs Flash BIOS 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 RAM. It retains
the Setup information when the power is turned off.
4.2.1 Entering Setup
Turn on the computer and press <Del> immediately. This will
allow you to enter Setup.

4.2.2 Standard CMOS Setup
When you choose the STANDARD CMOS SETUP option from
the initial setup menu, the screen shown on the following page
is displayed. The Standard Setup Menu allows users to
configure system components such as date, time hard disk
drive, and floppy drive. Once an option is highlighted, on-line
help information is displayed at the left bottom of the Menu
screen.
