1. INTRODUCTION

The AR-B1641 Series is a half-size tualatin Pentium® III/Celeron PIC Single Board Computer. Targeting on the rapid
growing networking, and telecommunication markets, the AR-B1641 Series are designed with Intel Dynamic Video
memory technology, and One-10/100M Base-TX Ethernet chips. This makes the AR-B1641 Series a perfect
solution for not only popular Networking Applications like Firewall, Gateway, and e-Server, but also for CTI
(Computer Telephony Integration) equipments such as PBX, Digital Logger, etc.

It accommodates up to 512MB SDRAM for demanding applications. Its 6-layer printed circuit board combining with
noise-tolerant and low power consumption CMOS technology enables the AR-B1641 Series to withstand any harsh
industrial environments very well.

The AR-B1641 Series SBC comes with hardware monitoring that monitors system and CPU temperature, system
voltages, fans Speed and CPU and chassis fan speeds to prevent unexpected system failures by warning the user
of adverse conditions. The power management feature provides power savings by slowing down the CPU clock,
turning off the monitor screen and stopping the HDD spindle motor to conserve energy. If the system stays idle for
certain period of time

Other standard specification include two serial ports (one RS-232 and one RS-232/422/485 selectable), one
multi-mode (ECP/EPP/SPP) parallel port, one floppy drive controller, and one PS/2 keyboard / mouse interface.
The built-in PCI Enhanced IDE controller supports up to four IDE devices and Ultra ATA / 100/66/33 bus master
modes.

For other more simple application, there is B version with one LAN.

1.1 FEATURES

n PCI Bus
n Support Intel Tualatin CPU up to 1.26GHz
n On-board One Intel 100/100BASE-TX Ethernet controllers
n Built-in AGP VGA, shared system memory up to 4MB
n Built-in Sound function

1.2 PACKING LIST

n AR-B1641 socket 370 bases Single Board Computer
n One FDD cable
n Two IDE Cable
n Keyboard / Mouse Adapter Y Cable
n One Printer Cable with bracket
n Two COM ports, one RS-232 and one RS-232/422/485

3.1 HARDWARE SETUP AND INSTALLATION

3.1.1 CPU Installation and Upgrading

CPU

AR-B1641 User’s Guide

Step 1 Locate the ZIF socket and open it by first pulling the lever of socket upward.

Step 2 Insert the CPU into the socket. Please keep the lever right angle when inserting CPU.

16

AR-B1641 User’s Guide

Step 3 When inserting the CPU please note the correct orientation as shown. The notched corner should point
toward the end of the lever.

Step 4 Push the lever down to close the socket.

Step 5 Attach the heatsink onto the CPU.
Step 6 Push the clip of heatsink downward to hock the ear of socket firmly.

Step 7 Finally attach the fan cable to the CPU fan header.

17

3.1.2 System Memory Installation

Step 1 Open latches of DIMM socket.

Step 2 Insert the RAM module into the DIMM socket.

AR-B1641 User’s Guide

Step 3 Press the latches into the notches of the RAM module.

4. BIOS SETUP

The AMI‘s ROM BIOS provides a built-in Setup program that allows user to modify the basic system configuration and
settings. The modified data will be stored in a battery-backed CMOS RAM so that these data will be retained even when
the power is turned off. In general, the information saved in the CMOS RAM stay unchanged unless there is
configuration change in the system, such as hard drive replacement or new equipment is installed. AMI is a registered
trademark of the American Megatrends, Inc.

4.1 RUNNING AMI BIOS

The Setup Utility is stored in the BIOS ROM. When the power of the computer system is turned on, a screen message
appears to give you an opportunity to call up the Setup Utility; while the BIOS will enter the Power On Self Test (POST)
routines. The POST routines perform various diagnostic checks while initializing the board hardware. If the routines
encounter an error during the tests, the error will be reported in either of the two different ways – (1) hear a series of
short beeps, or (2) see an error message on the screen display. There are two kinds of error: fatal or non-fatal. The
system can usually continue to boot up sequence with the non-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. After the POST routines are

Plug and Play Aware O/S: Set this option to “ Yes” if the operation system installed in the computer is Plug and
Play-aware. BIOS only detect and enable PnP ISA adapter cards that are required for system boot. The Windows 95
operating system detects and enables all other PnP-aware adapter cards. Windows 95 is PnP-aware. Set this option to
“ No” if the operating system (such as DOS, OS/2, Windows 3.x) does not use PnP.

Fail-Safe default setting is No.

Option Description

No

boot. This is the default setting.

Yes This option allows the PnP data to be rebuilt by the BIOS at every boot.

PCI Latency Timer (PCI Clocks): This option is used to control PCI latency timer period (follow PCI clocks). Based on
PCI specification 2.1 or later and PCI bus frequency in system, user can select different timer to meet their PCI bus
environment.

Primary Graphics Adapter: Initialize the PCI video display card on PCI slot before initializing any other display device
on the system. Thus the PCI slot display card becomes the primary display. Available options are [PCI] and [AGP].
Allocate IRQ to PCI VGA: This option will be used to allocate IRQ for PCI VGA card. In general, some of PCI VGA cards
needs IRQ support.

DMA Channel 0/1/3/5/6/7: These items specify the bus that the system DMA (Direct Memory Access) channel is used.
The settings determine if AMIBIOS should remove a DMA from the available DMAs passed to devices that are
configurable by the system BIOS. The available DMA pool is determined by reading the ESCD NVRAM. If more DMAs
must be removed from the pool, the end user can reserve the DMA by assigning an ISA/EISA setting to it.

BIOS. The available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must be removed from the IRQ
pool, the end user can use these settings to reserve the IRQ by assigning an ISA/EISA setting to it. Onboard I/O is
configures by AMIBIOS. All IRQs used by onboard I/O are configured as PCI/PnP. If all IRQs are set to ISA/EISA, and
IRQ14/15 are allocated to the onboard PCI IDE, IRQ9 will still be available for PCI and PnP devices. Settings: ISA/EISA

Normal The normal parallel port mode is used. This is the default setting.
Bi-Dir Use this setting to support bidirectional transfers on the parallel port.
The parallel port can be used with devices that adhere to the Enhanced

Parallel Port (EPP) specification. EPP uses the existing parallel port signals
to provide asymmetric bidirectional data transfer driven by the host device.

The parallel port can be used with devices that adhere to the Extended
Capabilities Port (ECP) specification. ECP uses the DMA protocol to
Achieve transfer rates of approximately 2.5 Mbs. ECP provides symmetric
Bidirectional communications.

parallel ports on computer systems use IRQ7 and I/O Port 378H as the standard setting.

previously set password from CMOS memory. You will be prompted to confirm the password. Retype the password and
press<Enter>. You may also press<Esc> to abort the selection and not enter a password.

To clear a set password, just press<Enter> when you are prompted to enter the password. A message will show up
confirming the password will be disabled. Once the password is disabled, the system will boot and you can enter Setup
without entering any password.

When a password has been set, you will be prompted to enter it every time you try to enter Setup. This prevents an
unauthorized person from changing any part of your system configuration.

Additionally, when a password is enabled, you can also have AMIBIOS to request a password each time the system is
booted. This would prevent unauthorized use of your computer. The setting to determine when the password prompt is
required is the PASSWORD CHECK option of the ADVANCED BIOS FEATURES menu. If the PASSWORD CHECK
option is set to Always, the password is required both at boot and at entry to Setup. If set to Setup, password prompt only
occurs when you try to enter Setup.

Note: About Supervisor Password & User Password
Supervisor Password : Can enter and change the settings of the setup menu.
User Password : Can only enter but do not have the right to change the settings of the setup menu.
