A WARNING indicates the potential for bodily harm
and tells you how to avoid the problem.

Preface

Disclaimer: We have tried to identify all situations that may pose a warning or
caution condition in this manual. However, ICS Advent does not claim to have
covered all situations that might require the use of a Caution or Warning.

Advisory Conventions xiii

Safety Instructions

Before handling the Dual BX , read the following instructions and safety
guidelines to prevent damage to the product and to ensure your own personal
safety. Refer to the “Advisories” section for advisory conventions used in this
manual, including the distinction between Warnings, Cautions, and Notes.

J Always use caution when handling/operating the computer. Only

qualified, experienced, authorized electronics service personnel should
access the interior of the computer. The power supplies produce high
voltages and energy hazards, which can cause bodily harm.

J Use extreme caution when installing or removing components. Refer to

the installation instructions in this manual for precautions and
procedures. If you have any questions, please contact ICS Advent
Post-Sales Technical Support.

WARNING

High voltages are present inside the chassis when the
unit’s power cord is plugged into an electrical outlet.
Turn off system power, turn off the power supply, and
then disconnect the power cord from its source before
removing the chassis cover. Turning off the system
power switch does not remove power to components.

When Working Inside a Computer

Before taking covers off a computer, perform the following steps:

xiv Preface

1) Turn off the computer and any peripherals.

2) Disconnect the computer and peripherals from their power sources to

prevent electric shock or system board damage.

3) Follow the guidelines provided in “Protecting Against Electrostatic

Discharge” on the following page.

4) Disconnect any telephone or telecommunications lines from the computer.

In addition, take note of these safety guidelines when appropriate:

J To help avoid possible damage to system boards, wait five seconds after

turning off the computer before removing a component, removing a
system board, or disconnecting a peripheral device from the computer.

J When you disconnect a cable, pull on its connector or on its strain-relief

loop, not on the cable itself. Some cables have a connector with locking
tabs. If you are disconnecting this type of cable, press in on the locking
tabs before disconnecting the cable. As you pull connectors apart, keep
them evenly aligned to avoid bending any connector pins. Also, before
connecting a cable, make sure both connectors are correctly oriented
and aligned.

CAUTION

Do not attempt to service the system yourself except as
explained in this manual. Follow installation and
troubleshooting instructions closely.

Preface

Safety Instructions xv

Protecting Against Electrostatic Discharge

Static electricity can harm system boards. Perform service at an ESD workstation
and follow proper ESD procedure to reduce the risk of damage to components.
ICS Advent strongly encourages you to follow proper ESD procedure, which can
include wrist straps and smocks, when servicing equipment.

You can also take the following steps to prevent damage from electrostatic
discharge (ESD):

J When unpacking a static-sensitive component from its shipping carton,

do not remove the component’s antistatic packing material until you
are ready to install the component in a computer. Just before
unwrapping the antistatic packaging, be sure you are at an ESD
workstation or grounded.

J When transporting a sensitive component, first place it in an antistatic

container or packaging.

J Handle all sensitive components at an ESD workstation. If possible,

use antistatic floor pads and workbench pads.

J Handle components and boards with care. Don’t touch the components

or contacts on a board. Hold a board by its edges or by its metal
mounting bracket.

xvi Preface

When Operating a Computer

When operating a computer, observe the following operating guidelines:

J To help prevent electric shock, plug computer power cables into

properly grounded power sources. Use cables equipped with
three-prong plugs to ensure proper grounding. Do not use adapter
plugs or remove the grounding prong from the cable.

J Be sure nothing rests on chassis cables and that cables are not located

where they can be stepped on or tripped over.

J Keep objects out of chassis openings. This can cause fire or electric

shock by shorting out interior components.

J Keep chassis away from radiators and heat sources. Do not block

cooling vents or place chassis in a closed-in wall unit.

J To help protect chassis from sudden, transient increases and decreases

in electrical power, use a surge suppressor, line conditioner, or
uninterruptible power supply (UPS).

J Consideration should be given to the connection of the equipment to the

supply circuit and the effect that circuit overloading might have on
overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this
concern.

Preface

J The ambient temperature within the rack may be greater than room

ambient temperature. Installation should be such that the amount of
air flow required for safe operation is not compromised. Consideration
should be given to the maximum rated ambient temperature.

Safety Instructions xvii

Rack Stability

Installation should be such that a hazardous stability condition is not achieved due
to uneven loading. The chassis should be secured to the rack frame with retaining
screws when it is slid in the rack. This will prevent the chassis from sliding
forward on the slide rails if the cabinet is tilted or vibrated, resulting in possible
mechanical or electrical damage to the system or injury to personnel.

WARNING

There is a real danger of a rack toppling if a heavy
chassis is extended on its slide rails from the rack. ICS
Advent strongly recommends you anchor the mounting
rack to the floor or wall to prevent this from
happening.

Safety Standards

The product(s) described in this manual has met the safety
requirements of Underwriters Laboratories (UL) for the US and
Canadian market based on UL’s published Standards for Safety.

Overview

The Dual BX single board computer (Figure 1-1) is designed to fit high performance
Pentium-III based CPUs and is compatible for high-end computer system
applications with PCI Local Bus architecture. It is designed to meet today’s
demanding pace, and keep complete compatibility with hardware and software
designed for the IBM PC/AT. With the onboard VGA and fast Ethernet interfaces,
you can build up a high performance and high data availability system for VARs or
system integrators.

This single board computer will operate with single or dual Intel Pentium III
processors, and support Dual Inline Memory Modules (DIMM) to 1GB DRAM. The
enhanced onboard PCI IDE interface is capable of supporting 4 drives to PIO mode
4 timing and the Ultra DMA/33 synchronous mode feature. The onboard Super I/O
Chipset integrates a floppy controller, two serial ports, one Fast Infrared FIR (FIR)
port and one parallel port. The high performance 16C550-compatible UARTs
provide 16-byte send/receive FIFOs, and the multi-mode parallel port supports
SPP/EPP/ECP functions. In addition, Universal Serial Bus (USB) ports are
packaged to provide high-speed data communication between peripherals and the
PC. The PICMG standard makes the Dual BX single board computer compatible
with the legacy ISA, ISA/PCI or multi-slots PCI-bus backplane. The onboard 32-pin
DIP sockets support M-systems’ Disk-On-Chip products up to 144MB. The
Watchdog Timer function allows users to monitor the system status. One 6-pin
Mini-DIN connector is provided to connect a PS/2 mouse and keyboard through a
Y-cable. The onboard Flash ROM is used for easy BIOS updates. Two standard

5.25-inch disk drive power connectors are reserved to directly induce sufficient
current required for large power applications, and the additional 5-pin shrouded
connector is reserved for connecting the keyboard interface on the backplane. The
high precision Real Time Clock/calendar is built-in to support the Y2K roll-over for
accurate scheduling and storing of configuration information. In addition, one 4­pin header is designed to support the ATX power function. All of these features
make the Dual BX single board computer excellent in stand-alone applications.

System Architecture

The following diagram will show you how the Dual BX single board computer gives
you a highly integrated system solution. The most current system architecture of
the Dual BX single board computer includes two main VLSI chips, 82443BX Host
Bridge and 82371EB PIIX4E, to support Pentium-III processors, SDRAM with
ECC, PCI bus interface, USB port, SMBus communication, and Ultra DMA/33 IDE
Master. The onboard super I/O chip, Intel© IOAPIC S82093AA, empowers PS/2
keyboard/mouse, two UARTs, FDC, Parallel and Infrared interface. AGP VGA
display and LAN provide more flexibility and reliability in a highly integrated
application.

The Dual BX single board computer has two built-in Socket 370 sockets to support
the Intel Pentium III Flip Chip Pin Grid Array (FC-PGA) processor for high
performance and cost-effective applications.

The North Bridge 82443BX provides a completely integrated solution for the
system controller and data path components in a Pentium III processor system. It
provides a 64-bit GTL+ based host bus interface, an optimized 64-bit DRAM
interface with ECC to support four 3.3V DIMMs at the maximum bus frequency of
100 MHz, and a 32-bit PCI bus interface to support 4 PCI masters for external
backplane support.

The South Bridge, 82371EB PCI ISA IDE Xcelerator (PIIX4E), provides a highly
integrated multifunction PCI-to-ISA bridge solution for the best industry
applications. It supports 2-channels dedicated to Ultra DMA-33 IDE master
interfaces, full Plug-n-Play compatibility, and Advanced Programmable Interrupt
Controller (APIC) interface. It also supports a 2-port USB feature and PCI 2.1
Compliance operation. In addition, it also provides XD-bus via buffer logic control
to support BIOS read/write access and the external real-time clock (RTC) to
maintain date and time of a system.

Introduction

The Super I/O chip Intel IOAPIC S82093AA, which integrates two high-speed
serial ports, one parallel port, an FIR/SIR interface, a 8042 keyboard controller
with PS/2 mouse ports and an FDD interface. This parallel port supports one
PC-compatible printer port (SPP), Enhanced Parallel Port (EPP) and Extended
Capabilities Port (ECP).

System Architecture 1-9

A standard 16-bit ISA bus interface is applied for all slower I/O operations. The
Dual BX single board computer contains a Watchdog Timer (WDT) enabled and
triggered by software, Disk-On-Chip (DOC) for M-systems Flash disk, and ISA
buffer driving for special I/O applications and multi-ISA slots. An advanced
feature is used on the Dual BX single board computer to detect the CPU
temperature. CPU operation will be automatically forced to slow down when
overheating happens. The onboard AGP device, graphics display port, powered by
CHIPS 69000 graphics accelerator supports one VGA display. Another onboard
PCI device, the LAN port, powered by the Intel 82559 10/100 fast Ethernet
controller supports a fast Ethernet interface through the RJ-45 port.

This chapter provides the definitions and locations of jumpers, headers, and
connectors. All of the configuration jumpers on the Dual BX single board computer
are shipped with the default settings. The default settings are marked with a star

*

(

).

Jumpers

In general, the jumpers are used to select options for certain features (Figure 2-1).
Some of the jumpers are user-configurable, allowing system enhancement. Other
jumpers are used for testing purposes only and should not be altered. To select any
option, insert the jumper cap (Short) or remove (NC) the jumper cap from the
jumper pins according to the following instructions. (Here NC stands for “Not
Connected”. )

Note: To determine the correct jumper settings, calculate the

CPU Core/Bus Ratio as follows:

Core/Bus Ratio = processor speed divided by base speed

Base Speeds: Pentium III = 100MHz

Example: The Core/Bus Ratio of a 700MHz Pentium III

processor is calculated as 700MHz divided by 100MHz = 7.0

Overview

This chapter describes how to set up your system, install M-system’s Flash disk,
set up the LCD display, and handle WDT operation.

Socket 370 Processor

Installing CPU1 and CPU2

1) Note the CPU speed and voltage type to adjust the jumper settings

properly.

2) Lift the CPU socket lever outwards and upwards.

3) Align the processor pins with the pin holes in the socket. Make sure the

notched corner or dot mark (pin 1) of the CPU corresponds to the socket’s

beveled end. Press the CPU gently until it fits into place.

4) Push down the lever to lock the processor chip into the socket.

5) Follow the installation instructions for the cooling fan and heat sink to

mount it on the CPU surface and lock it on the socket 370.

Note: The Dual BX single board computer allows operation
using a single processor.

Removing a CPU

1) Unlock the cooling fan.

2) Lift the CPU socket lever outwards and upwards.

3) Carefully lift the CPU out of the socket.

System Installation

Overview 3-3

Main Memory

The Dual BX single board computer provides four 168-pin Dual In-line Memory
Modules (DIMM) to support onboard main memory. The maximum memory size
for 3.3V Extended Data Out (EDO) DRAM or Synchronized DRAM (SDRAM) is
1GB. Normally, the DIMM used can be either 3.3V EDO memory with a speed less
than 70ns or 3.3V SDRAM with a speed less than 100ns. If you use a Pentium III
processor with a 100MHz system clock, use SDRAM with a speed less than 80ns (-

8); it is best to use PC100-compliant memory.

For system compatibility and stability, do not use generic DIMM. Use single- or
double-sided DIMM without parity and ECC functions.

Watch out for the contact and lock integrity of memory modules while they are in
the socket, it will impact on the system reliability. Follow the normal procedure to
install your DRAM module into the memory socket. Before locking, make sure that

the module has been fully inserted into the card slot.

Note: Do not change DRAM from setup defaults. See Chapter 4
for details.

3-4 System Installation

Flash Disk

The Dual BX single board computer includes one 32-pin DIP socket for installing
Flash disk from 2MB to 288MB, such as those from M-systems. This operation
structure operates with pure ISA bus without the Plug-n-Play (PnP) function.
Before installing it, make certain that the I/O address jumper setting is set to the
correct position to prevent an I/O resource conflict. Remember to follow the Disk­On-Chip (DOC) installation procedure to prevent the Flash chip from burning out
due to incorrect installation.

Installing DOC

CAUTION

Make sure your DOC is properly inserted. Placing the
DOC in reverse will damage it severely.

Align the DOC with the pin holes on the socket. Make sure that the notched corner
or dot mark (pin 1) of the DOC corresponds to the notched corner of the socket.
Then press the DOC gently until it fits into place. When correctly installed, the
Flash disk can be viewed as a normal hard disk to access read/write data.

If you want to boot from the Flash disk, refer to the application note from
M-systems. You can easily obtain information from M-system’s shipping package
(such as the product manual) or their Web site: (www.m-sys.com).

System Installation

Flash Disk 3-5

Installing the Single Board Computer

To install the Dual BX single board computer into a chassis, perform the following
steps:

1) Ensure all jumpers are set properly.

2) Install and configure the CPU and memory module.

3) Place the Dual BX into the dedicated position in your system.

System Installation

LCD Driver Support

Note: For successful installation of the VGA driver in
NT4.0 environments, ICS Advent recommends that you build a
diskette with the VGA drivers to support a valid data path to
“Disk 1”. Please prepare one diskette and create a directory
\disk1 under its root. Copy all files under \Drivers\Graphics
from the CD into \disk1. Then when prompted for VGA drivers
during the installation of NT4.0, the VGA drivers will all be
located on the diskette.

The Dual BX onboard VGA (or 69000) device drivers are provided on CD. Before
installing the device driver, please see the reference files in each sub-directory.

The VGA69000 supports NT4.0, Win95, Win98, and Win2000 environments.

2-3 Disable the onboard Ethernet

Ethernet Driver Support

The 82559 LAN driver is located in the Drivers directory under the Ethernet
subdirectory of the CD.

Onboard LED Indicator (for LAN status)

The Dual BX provides three LED indicators to show the status of the LAN
interface. These messages will assist in troubleshooting.

3-8 System Installation

LED1 (left) (LAN Link Integrity LED)

ON: indicates link is good in either 10 or 100Mbps
OFF: link is bad

LED2 (right) (LAN active LED)

ON: indicates Tx/Rx activity
OFF: no activity

LED3 (center) (LAN speed LED)

ON: indicates 100Mbps activity
OFF: indicates 10Mbps activity

Onboard 68-pin PCI Connector

The Dual BX single board computer provides one onboard 68-pin PCI connector
that allows you to apply additional PCI devices, such as SCSI or Ethernet. If you
have a compatible PCI device, simply plug it onto the connector and secure it with

two retention bars.

Note: If you plug a bus-mastering PCI device, such as a SCSI
or Ethernet device, into this 68-pin PCI connector, this PCI
device will consume one REQ and GNT pair signal designed on
the primary PCI slot #3. In this case, only a non-bus-mastering
PCI device is allowed to sit on primary PCI slot #3.

CHIPS 69000 Graphics Controller 3-9

System Installation

Clear CMOS Operation

The following table indicates how to enable/disable the CMOS Clear Function
hardware circuit by putting jumpers at their proper positions.

JP1 FUNCTION

NC Normal Operation

Short Clear CMOS Contents

To correct operate CMOS Clear function, users may apply a jumper over JP1
always (this will not consume any power), and configure in the BIOS (Advanced
Chipset Setup) CMOS RAM Clear Function to “Enabled”. Reboot system will then
produce a “CMOS Check Sum Error” message and hold up the system. Users may
then follow the displayed message to load in BIOS default setting.

Watchdog Timer Programming

The super I/O chipset, Intel IOAPIC S82093AA, provides a mechanism for
Watchdog Timer operation. As there is no hardware jumper on the Dual BX to
enable the Watchdog Timer, users need to produce a program to enable and start
the Watchdog Timer. There is one programming guide (source code in C language)
and test program in Appendix A, "WDT Programming".
Please refer to the programming guide in Appendix A to create your own
Watchdog Timer application.

Overview

The Dual BX single board computer is equipped with AMI BIOS, which is stored in
Flash ROM. AMI BIOS features a built-in setup program, allowing users to modify
the system configuration. The system configuration is stored in CMOS RAM so it is
retained during power-off periods. When the computer is turned on, the Dual BX
single board computer communicates with peripheral devices and checks its
hardware resources against the information stored in CMOS memory. If an error is
detected or CMOS parameters need to be initially defined, the diagnostic program
will prompt the user to enter the SETUP program. Some errors will abort the
start-up.

The Setup program is for viewing and changing the BIOS settings for a computer.

Entering Setup

First Method

1) Setup can be accessed by pressing the [F2] key after the POST memory test

begins and before the operating system boot begins.

Second Method

1) Turn on or reboot the computer.

CMOS Display Type Wrong” message

Password Check

This option enables password checking when the system boots up or runs the
CMOS Setup. It only takes effect after setting the Change Supervisor Password.

Setup – This option will force the system to run a password check before running
setup if you have already entered the current user password in “Change User
Password”. The system will boot, denying access to setup.

Always – Password prompt appears every boot-up. The system will not boot and
will deny access to Setup with an invalid password. The best method is to clear
CMOS or to reload BIOS Setup to boot up the system.

Boot To OS/2 > 64MB

BIOS Setup

Set this option to Yes to support the OS/2 environment.

System BIOS Cacheable

Enable this option to enhance system performance by shadowing and caching
system BIOS. When disabled, this BIOS shadow function will be ignored.

Advanced CMOS Setup Menu 4-17

Shadow Memory (from address C000 – DFFF, 16K per segment)

Each segment provides three options Disabled, Enabled, and Cached for a
faster adapter’s ROM execution. However this shadow function is chipset oriented
and dependent on system hardware features. In general, C000 and C800 will be
allocated for VGA BIOS and set to Cached to get a higher display performance
using the shadowing and caching features. If the user chooses the Enabled
setting, only the BIOS shadow function is active.

4-18 BIOS Setup Information

Advanced Chipset Setup Menu

This setup is very important to maintain system stability. The optimal default
setting is recommended.

Configure SDRAM Timing by SPD

This option provides DIMM Plug-n-Play support by the Serial Presence Detect
(SPD) mechanism via the System Management Bus (SMBus) interface. You can
disable this option to manage the following four SDRAM timing options by
yourself. In addition, SDRAM operating timings may follow serial presence from
the EEPROM content by setting this option to Enabled, and all of SDRAM timing
options will be not available and hidden.

SDRAM RAS# to CAS# Delay

This option controls the number of SDRAM Clocks (SCLKs) from a row activate
command to a read or write command. Normally, the option will be set to
3 SCLKs.

SDRAM RAS# Precharge

This option controls the number of SCLKs for RAS# precharge.

BIOS Setup

SDRAM CAS# Latency

This option controls the number of SCLKs between the time a read command is
sampled by the SDRAMs and the time the North Bridge, 82443BX, samples
correspondent data from the SDRAMs. For a registered DIMM with CAS#
Latency = 2, this option should be set to 2 SCLKs to acquire better memory
performance.

SDRAM Leadoff Cmd Timing

This option is used to control when the SDRAM command pins (SRASx#, SCASx#
and Wex#) and CSx# are considered valid on leadoffs for CPU cycles. If you select
Auto, this timing will be automatically initialized and set by the BIOS.

Advanced Chipset Setup Menu 4-19

DRAM Integrity Mode

There are three options in this feature: Non-Error Checking and Correction
hardware (Non-ECC), Error Check Only (EC-Only) and Error Checking and
Correction Hardware (ECC). The DRAM integrity mode will be implemented by
the parity algorithm when this option is set to Non-ECC.

DRAM Refresh Rate

This option specifies the refresh rate frequency for the installed system memory
SDRAM DIMMs.

Memory Hole

This option allows the end user to specify the location of a memory hole for
memory space requirements from ISA-bus cards.

8bit I/O Recovery Time

This option specifies the length of the delay (in Sysclks) inserted between
consecutive 8-bit I/O operations.

16bit I/O Recovery Time

This option specifies the length of the delay (in Sysclks) inserted between
consecutive 16-bit I/O operations.

USB Passive Release

When enabled, this allows PIIX4 to use Passive Release to obtain better USB
performance while transferring control information or data for USB transactions.
When disabled, PIIX4 will perform PCI functions for the USB without using
Passive Release.

PIIX4 Passive Release

Choose the Enabled option to help raise the available bandwidth of the PCI bus
for increasing PCI bus performance.

4-20 BIOS Setup Information

PIIX4 Delayed Transaction

Choose the Enabled option to increase PCI bus performance for slower ISA bus
applications.

Spread Spectrum Control

This option is for Electromagnetic Interference (EMI) test issues only.

USB Function

This option will enable the on-chip USB function to support USB peripheral
devices if the user chooses the Enabled setting.

USB Keyboard Legacy Support

This feature will be automatically disabled and hidden if the user chooses the
Disabled setting from the foregoing USB Function option. Otherwise, enabling
this option provides support for a USB keyboard without the auxiliary driver in a
DOS environment.

CMOS RAM Clear Function

If your system supports Y2K RTC, set this option to Enabled to support the
hardware CMOS clearing operation.

BIOS Setup

Advanced Chipset Setup Menu 4-21

Power Management Setup Menu

This APM (Advanced Power Management) determines how much energy can be
saved by setting the below items to handle system power resources. The following
descriptions will specify the definition of each item.

Power Management/APM

Use this feature to control system power resources. Set this option to Enabled to
enable the power management function. It becomes effective when based on the
following parameter settings.

Green PC Monitor Power State

This option is used to decide what kind of power states are effective. There are
three options Standby, Suspend, and Off . The Standby option is to turn off
light power by handling monitor signals. The Suspend mode is to turn off heavy
power. The Off state is really to turn off the power of the monitor.

Video Power Down Mode

This option specifies the power conserving state that the Video Electronics
Standards Association (VESA) VGA video subsystem enters after the specified
period of display inactivity has expired.

Hard Disk Power Down Mode

This option specifies the power management state that the HDD enters after the
specified period of hard drive inactivity has expired. It is the same as video power
control. If the user chooses Standby or Suspend, it will depend on the duration of
Standby Time-out or Suspend Time-out.

Standby Time-out (Minute)

This option specifies the length of the period of system inactivity while the
computer is in a full-on power state before the computer is placed in Standby
mode. When this length of time expires, the computer enters the Standby Time-
out state. In Standby mode, some power use is curtailed.

4-22 BIOS Setup Information

Suspend Time-out (Minute)

This option is the same as the Standby Time-out function. These two features
are enabled to monitor the power of sub-items Display Activity, Serial Port,
Parallel Port, Floppy, Pri-HDD, and Sec-HDD independently. It is also used to
control CPU throttle running function. All of the sub-items will be ineffective in
disabling Standby Time-out or Suspend Time-out even if they can be chosen by
the user in the BIOS setup menu.

Throttle Slow Clock Ratio

This option specifies the speed at which the system clock runs in power saving
modes. The settings are expressed as a duty cycle of the STPCLK# signal. This
duty cycle indicates the percentage of time the STPCLK# signal is asserted while
in the throttle mode.

Display Activity

This option specifies whether the BIOS will monitor activity on the display monitor
for power conservation purposes. If set to Monitor and the computer is in a power
saving state, BIOS watches for video display activity. The computer enters the full­on power state if any activity occurs. BIOS reloads the Standby and Suspend
timeout timers if activity occurs on the specified IRQ lines. If set to Ignore, video
display monitor activity is not monitored.

BIOS Setup

Device 6/7/8/5/0/1/2/3 (Serial 1&2, Parallel, FDD, Pri/Sec HDD)

When set to Monitor, these options enable event monitoring on the specified
hardware device. If set to Monitor and the computer is in a power saving state,
BIOS watches for activity on the device with specified IRQ line. The computer
enters the full-on power state if any activity occurs. BIOS reloads the Standby and
Suspend time-out timers if activity occurs on the specified device. No monitoring
activity occurs if the option is set to Ignore. The settings for each of these options
are Monitor or Ignore.

Power Management/APM 4-23

Power Button Function

This feature is only available on systems with an ATX power control interface. If
you use a standard AT power supply, this option will be ignored. If you set it to
on/off, you can easily power on/off the system by pressing the power button
(toggle switch). However, if the Suspend setting is chosen, the system will be
forced into suspend mode when the user turns it off, unless the power button is
continuously pressed for more than 4 seconds to initiate soft off mode.

Ring Resume From Soft Off

This item wakes up the system from remote ringing control under a soft off
condition. If you choose the Disabled setting, the system will not be resumed by a
modem ring.

4-24 BIOS Setup Information

PCI/Plug-n-Play Setup

This section describes how to configure the PCI bus system. PCI is a system which
allows I/O devices to operate at speeds close to the CPU’s speed when they
communicate.

All of the options described in this section are important and technical and it is
strongly recommended that only experienced users make changes to the default
settings.

Plug-n-Play Aware O/S

Set this option to Yes if the operating system installed in the computer is
Plug-n-Play (PnP) aware. The BIOS only detects and enables PnP ISA adapter
cards that are required for the system to boot. The Windows 95/98/2000 operating
systems detect and enable all other PnP aware adapter cards and are PnP aware.
Set this option to No if the operating system (such as DOS, OS/2, Windows 3.x)

does not use PnP.

Note: Set this option correctly or the PnP aware adapter cards installed in
your computer will not be configured properly.

BIOS Setup

Clear NVRAM

This option is used to clear NVRAM and to check or update the Extended System
Configuration Data (ESCD) data after a system power on. Setting this option to
No will not clear NVRAM. Updating the ESCD is effective in a different ESCD
data comparision. If you select the Yes setting, the BIOS will update the ESCD
every power on.

PCI Latency Timer (PCI Clocks)

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

PCI/Plug-n-Play Setup 4-25

PCI VGA Palette Snoop

Some display cards that are non-standard VGA, such as graphics accelerators or
MPEG video cards, may not show colors properly. You can choose the Enabled
setting to correct this display mismatch problem. Supporting ISA adapter cards
installed in the computer requires VGA palette snooping.

Allocate IRQ to PCI VGA

This option will be used to allocate an IRQ for a PCI VGA card.

PCI IDE BusMaster

Set this option to Enabled to specify that the IDE controller on the PCI local bus
has a bus mastering capability.

Offboard PCI IDE Card

This option specifies if an offboard PCI IDE controller adapter board is used in the
computer. You must also specify the PCI expansion slot on the single board
computer (SBC) where the offboard PCI IDE controller card is installed. If an
offboard PCI IDE controller is used, the onboard IDE controller on the SBC is
automatically disabled. If Auto is selected, BIOS automatically determines the
correct setting for this option. If you want to respectively control offboard PCI IDE
primary/secondary IRQ resources, you should set this option between Slot 1 and
Slot 4. Otherwise, all of these sub-options will not be available.

Offboard PCI IDE Primary/Secondary IRQ

This option specifies the PCI interrupt used by the primary/secondary IDE
channel on the offboard PCI IDE controller. The settings are Disabled, INTA,
INTB, INTC, INTD, or Hardwired for installing offboard non-compliant
PCI IDE cards.

PCI Slot 1/2/3/4 IRQ Priority

These options specify the priority IRQ to be used for PCI devices installed in PCI
expansion slots 1 through 4, but do not force selection. The settings are Auto (AMI
BIOS automatically determines the priority IRQ), (IRQ) 3, 4, 5, 7, 9, 10, or 11.

4-26 BIOS Setup Information

DMA Channel 0/1/3/5/6/7

These options specify if the named DMA channel is available for use on the ISA/
EISA bus or PnP.

IRQ 3/4/5/7/9/10/11/12/14/15

These options specify the bus that the named interrupt request lines (IRQs) are
used on. These options allow you to specify IRQs for use by legacy ISA adapter
cards. These options determine if AMI BIOS should remove an IRQ from the pool of
available IRQs passed to devices that are configurable by the system BIOS. The
available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs are
needed, the user can use the PCI/PnP setup to remove the IRQ by assigning the
option to the ISA/EISA setting. All IRQs used by onboard I/O peripherals are
configured as PCI/PnP.

BIOS Setup

PCI/Plug-n-Play Setup 4-27

Peripheral Setup

This section describes the I/O resources assignments for all onboard peripheral
devices.

Onboard FDC

If you want to install a different add-on super I/O card to connect floppy drives, set
this field to Disabled. Otherwise, set it to Auto to call BIOS to automatically
determine if the floppy controller should be enabled.

Onboard Serial Port A/Port B

These fields control the resource assignments of two onboard serial interfaces:
SIO1 and SIO2. The following list shows the options of onboard serial
port A/port B:

Auto à set serial I/O resources automatically
Disabled à indicates onboard COM port function is disabled
3F8h/COM1 à assign I/O address 3F8h to COM1
2F8h/COM2 à assign I/O address 2F8h to COM2
3E8h/COM3 à assign I/O address 3E8h to COM3
2E8h/COM4 à assign I/O address 2E8h to COM4

Onboard IR Port

This option controls the resource assignments of onboard serial port 3. The IR
Mode Select has three settings IrDA, ASK IR, and FIR.

4-28 BIOS Setup Information

Onboard Parallel Port

There are four optional items used to control the onboard parallel port interface
while the user selects the I/O base address manually: Parallel Port Mode, EPP
Version, Parallel Port IRQ, and Parallel Port DMA Channel. The following
lists the available options of the onboard parallel port:

Auto à LPT port I/O resources assigned automatically
Disabled à onboard parallel port function is disabled
378h à IRQ7 for this default I/O address
278h à assign this I/O address to LPT1
3BCh à assign this I/O address to LPT1

Parallel Port Mode:

This option specifies the parallel port mode. ECP and EPP are both bi-directional
data transfer schemes that adhere to the IEEE 1284 specifications. This parallel
port mode includes four options: Normal, Bi-Dir, EPP, and ECP. The optimal
default setting is Bi-Dir.

S e t t i n g De sc ri pt io n

Normal Uni-direction operation at normal speed

Bi-Dir Bi-direction operation at normal speed

BIOS Setup

EPP 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 bi-directional
data transfer driven by the host device.

ECP The parallel port can be used with devices that adhere to the

Extended Capabilities Port (ECP) specification. ECP uses the
DMA protocol to achieve data transfer rates up to 2.5 Megabits
per second. ECP provides symmetric bi-directional
communication.

Peripheral Setup 4-29

EPP Version:

This option is only valid if the parallel port mode option is set to EPP. This option
specifies the version of the Enhanced Parallel Port specification that will be used
by the AMI BIOS.

Parallel Port IRQ:

This option is only valid if the onboard parallel port option is set to Enabled. This
option sets the IRQ used by the parallel port.

Parallel Port DMA Channel:

This option is only available if the onboard parallel port is set to a fixed I/O
address and the setting of parallel port mode is ECP. This option sets the DMA
channel used by the ECP-compatible parallel port.

Onboard IDE

This option specifies the onboard IDE controller channels that will be used. The
settings are Disabled, Primary, Secondary, or Both.

4-30 BIOS Setup Information

Hardware Monitor Setup

This setup describes the current system status detected by the hardware monitor
sensor. The status shown on screen will include:

I Current CPU Temperature (Generally indicates the surface

temperature of the SBC),

I Current Chassis Fan Speed,

I Current CPU1 and CPU2 Fan Speed, and

I System operating voltages including Vcore, Vtt, Vcc3, +5V, +12V,

-12V, and -5V.

BIOS POST Check Point List

The AMI BIOS provides all IBM standard Power On Self Test (POST) routines as
well as enhanced AMI BIOS POST routines. The POST routines support CPU
internal diagnostics. The POST checkpoint codes are accessible via the
Manufacturing Test Port (I/O port 80h).

During the POST, the BIOS signals a checkpoint by issuing one code to I/O address
80h. This code can be used to establish the status of the BIOS power-on sequence
and what test is currently being performed. This is done to help troubleshoot a
faulty system board.

BIOS Setup

If the BIOS detects a terminal error condition, it will halt the POST process and
attempt to display the checkpoint code written to I/O address port 80h. If the
system hangs before the BIOS detects the terminal error, the value at port 80h will
be the last test performed. In this case, the terminal error cannot be displayed on
the screen. The following POST checkpoint codes are valid for all AMI BIOS
products with a core BIOS date of 07/15/95.
