Motherboard Feature Introduction

Based on Intel’s 810 GMCHset & ICH (82810-DC100 + 82801)
chipsets, the BIW1A is an advanced motherboard that comes with onboard
audio and video capabilities, an audio modem riser slot, a 4MB BIOS that
includes built-in anti-virus protection and UltraDMA/66 technology for
lightning-fast IDE transfer speeds.

The BIW1A is an ATX-sized motherboard, measuring 305mm by 173
mm, and it uses a four-layer printed circuit board. Designed for a Socket 370
CPU, the BIW1A also includes two DIMM sockets for the addition of up to
512MB of memory. The bus system supports speeds of 66MHz to 100MHz,
which means either inexpensive 66MHz or high-performance 100MHz
memory modules can be added to the system.

In addition to its 32-bit onboard sound functionality, the BIW1A comes
with an integrated VGA adapter with 2D and 3D graphics engines and 4MB
of onboard video memory. An audio modem riser slot is included as well as
hardware monitoring and wake-on LAN capabilities. Built-in anti-virus
protection ensures you will maintain a clean operating environment free of
unwanted viruses. The BIW1A also features UltraDMA/66 technology,
which allows for Master IDE transfer rates of up to 66MB/sec.

The BIW1A is a powerful platform that leverages the benefits of a low­cost system with high-performance functionality, and we are confident you
will see for yourself how convenient this motherboard is when you assemble
your system.

FEATURES

Full-function Processing -

Intel’ s new-generation chipset—t he Intel 810 GMCHset —supports all Socket
370 and compatible processors. The motherboard comes with many excellent
functions built in, such as an audio modem riser slot, onboard 3D graphics,
UltraDMA/66 support and built-in anti-virus protection. The motherboard
enables users to move up to optimized performance at a low cost. Processor

~2~

BIW1Aseries

speed configurations are automatically set through the board’ s firmware,
which means changing switch or jumper settings on the motherboard is not
necessary.

High Performance -

The board has two DIMM sockets for the installation of 168-pin, 3.3V non­buffered DIMM memory modules. The DIMM memory modules must be
SDRAM memory chips. The board supports a memory bus of 100/66MHz,
and each DIMM socket can accept modules up to 256MB in capacity for up
to 512MB of total system memory.

3D Graphic VGA & Clear 32-bit Audio Built In -

Full multimedia function is integrated onto the motherboard, which means
you won’ t need to spend extra money on additional adapters, processors and
cards. Either 2D or 3D graphics can be displayed, and the motherboard
comes with a 4MB onboard SDRAM display cache that supports 1024 X 768
X 16-bit 3D graphics and 1600 X 1200 X 8-bit color 2D graphics. AC’ 97
DAC/ADC, which is built into the audio CODEC, reduces noise and results
in improved audio quality and performance for a signal to noise ratio of
+90dB. These features greatly improve voice synthesis and recognition.

Double or Quadruple IDE Transfer Speeds -

IDE transfers using UltraDMA/33 Bus Master IDE technology can handle
rates of up to 33MB/sec., while UltraDMA/66 technology supports IDE
transfer speeds of 66MB/sec. Best of all, this technology is compatible with
existing ATA-2 IDE specifications, so there is no need to upgrade current
IDE devices or cables.

Slot Expansion Options -

The motherboard has a full set of expansion slots, with five usable slots: four
32-bit PCI slots and one 8/16-bit ISA slot. The ISA slot and one PCI slot
share the same physical area, which means you cannot use both at the same
time.(BIW1A-I only)

Integrated I/O -

With its built-in Windbond I/O chip, this motherboard has a comprehensive
set of integrated I/O ports. The I/O port array features PS/2 keyboard and
mouse ports, a parallel port, two USB ports, two serial ports, a monitor port,
a game/MIDI port, and three audio jacks. You may also use the built-in

~3~

BIW1Aseries

motherboard header to add in an infrared port. In addition, the motherboard
has two PCI-IDE channels and a floppy disk drive interface.

ACPI Ready -

APCI (Advanced Configuration and Power Interface) technology provides
for more energy saving functions for future operating systems supporting OS
Director Power Management (OSPM) functionality. With these features
implemented in the operating system, your system can be ready around the
clock while meeting all energy-saving standards.

Programmable Firmware -

The motherboard includes a 4MB Award BIOS that allows CPU
parameters to be set through the BIOS. The firmware BIOS includes a new,
easy-to-use interface that gives users more control over their system’ s
performance. The fully programmable firmware provides enhanced system
features and allows users to set power management, CPU and memory timing
levels, as well as LAN and modem wake-up alarms.

Sockets permit system memory expansion from 8MB to 512MB. Each bank
provides a 64-bit wide data path. You can install 100MHz SPD RAM or
66MHz SDRAM into the motherboard, using your CPU clock to make the
selection.

If you want to install more memory and there are no sockets available,
you must remove some installed modules and replace them with the upgrade
modules.

If you have to do this, be sure to identify what type of memory is already
installed. In some cases, there may be a mix of module types. You can
confirm this by checking the configuration screen that appears while the
computer is starting up. Press the pause key to temporarily interrupt the start­up so that you have more time to read the screen. When you’ re done, press
any key to resume.

Remove the lowest performance and smallest size modules and replace
them with the upgrades.

How to Install DIMM Modules on Motherboard

1. The SDRAM sockets are keyed with notches and the DIMMs are keyed

with cut-outs so that they cannot be installed incorrectly. Check that the
cut-outs on the DIMM edge connector match the notches in the SDRAM
socket. In other words, before inserting the DIMM, make sure the pin1 of
the DIMM matches with the pin1 on the DIMM socket.

2. Push down the latches on each side of the SDRAM socket.

3. Install the DIMM into the socket and press it carefully but firmly down so

that it seats correctly. The latches at either side of the socket will be
levered upwards and latch on the edges of the DIMM when it is installed
correctly.

How to Remove DIMM Modules from Motherboard

1. Press the holding latches at either side of the socket outward to release the

DIMM.

2. Gently pull the DIMM out of the socket.

CPU & Power Supply Fan Connectors (3-pin FanPWR)

These connectors support cooling fans of 500mAMP (6 watts) or less.
Position the fans so that the heat-sink fins allow the airflow to go across the
onboard heat-sink(s) instead of the expansion slots. Depending on the fan
manufacturer, the wiring and plug may be different. The red wire should be
positive, while the black one should be grounded. Connect the fan's plug to
the board, taking into consideration the polarity of this connector.

The "rotation" signal is to be used only by a specially designed fan with a
rotation signal.

The CPU and motherboard will overheat if the hot air generated

by the CPU does not flow across the onboard heat-sinks, and the
CPU fan and motherboard can be damaged if these pins are used
improperly.

2.3-4 Installing the Motherboard

The BIW1Aseries motherboard complies with the specifications for an ATX
board, so you can also install this kind of board into a full-size ATX case.
Some features on the motherboard are implemented by cabling connectors on
the motherboard to indicators and switches on the system case. Ensure that
your case supports all the features required. The BIW1A
can support one or two floppy diskette drives and four enhanced IDE drives.
Ensure that your case has sufficient power and space for all the drives that
you intend to install.

2.3-5 Installing the interface card

This section explains how to install new interface cards on your
motherboard. It covers installing ISA cards and PCI cards. There are five
expansion card slots on the motherboard, four PCI slots and one ISA
slots.(BIW1A-Ionly) When you get an expansion card, it will come with
instructions on how to install it, so this section covers relevant information
for the motherboard only.

PCI Cards and Slots

With very few exceptions, any PCI expansion card you are likely to get
will be Plug and Play compliant. If you are using an Operating System that
supports PnP, such as Windows 98/95, you should be able to follow the
installation instructions that come with the card and have the Operating
System automatically recognize and configure the card.

The PCI slots on the motherboard all have “Bus Master” capability. For
installed PCI cards to use this feature, an Operating system specific Bus
Master software driver that comes with this motherboard must be installed
under your Operating System. These drivers are located on the support Disk.

ISA Cards and Slots (BIW1A-I only)

ISA expansion cards often use system resources in the form of IRQs and
DMA channels. Newer cards that comply with the Plug and Play (PnP)
standard are designed to allow the Operating System to automatically
configure system resources. Cards that do not support PnP may require
manual configuration of both the card hardware and settings in the CMOS
Setup Utility.

If you have a PnP compliant card to install, there should be little to do
other than follow the installation instructions. If, however, you have a non­PnP card and it requires configuring system resources, you may need to setup
the configuring expansion card resources in CMOS Setup.

2.3-6 Installing Accessory Cables

This section describes how to connect the accessory cable that motherboard
or system housing supports. In the case of ATX, there is no need to use a
bracket to extend the connectors to the rear panel, so here we will discuss
only the installation instructions for Floppy, IDE. Power supply and Front
Panel switch/LED cables.

! Caution: Make sure that the power supply is OFF before

connecting or disconnecting any bracket or cable.

ATX Power Cable

The 20-pin ATX power cable supports 5V standby current and soft
power-on switch. The soft power switch can be either momentary or toggle
type and must comply with the ATX specification.

Chapter 3

Award BIOS Setup

This chapter explains how to use and modify the BIOS setup utility that
is stored on the motherboard. The setup utility stores information about the
motherboard components, and the configuration of other devices that are
connected to it. The system uses this information to test and initialize
components when it is started up, and to make sure everything runs property
when the system is operating.

The setup utility is installed with a set of default values. The default
values are designed to ensure that the system will operate adequately. You
will probably have to make changes to the setup utility whenever you add
new components to your system such as new disk drives. You may be able to
generate increased performance by changing some of the timing values in the
setup, but this can be limited by the kind of hardware you are using, for
example the rating of your memory chips. In certain circumstances, the
system may generate an error message which asks you to make changes to
the setup utility. This happens when the system finds an error during the
POST (power on self test) that it carries out at start up.

Starting the Setup Utility

You can only start the setup utility shortly after the computer has been
turned on. A prompt appears on the computer display which says " Press
DEL to run Setup”. When you see this prompt press the Delete key, and the
system will start the setup utility and display ft main menu of the utility.

Using the Setup Utility

When you press the Delete key to start setup, the main menu of the
utility appears.

The main menu of the setup utility shows a list of the options that are
available in the utility. A highlight shows which option is currently selected.
You can use the cursor arrow keys to move the highlight to other options.

~31~

BIW1Aseries

When an option is highlighted, you can execute the option by pressing the
Enter key. Some options lead to dialog boxes which ask you verify that that
you wish to execute that option. You usually answer these dialogs by typing
Y for yes and N for no.

Some options lead to dialog boxes which ask for more information.
