Introduction

1.6 What is AGP

?

The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI
bridge device that supports an AGP port. The main purpose of the AGP port
is to provide fast access to system memory.

The AGP port can be used either as fast PCI port (32-bits at 66MHz vs.32­Bits at 33MHz) or as an AGP port which supports 2x data-rate, a read queue,
and side band addressing. When the 2x-data rate is used the port can
transmit data at 533MB/sec (66.6*2*4). The read-queue can be used to
pipeline reads – removing the effects of the reads-latency. Side band
addressing can be used to transmit the data address on a separate line in
order to speed up the transaction.

3.1. UNPACKING

The main board package should contain the following:

• The BX2000 main board.

• The Universal Retention Mechanism & Attach Mount

• USER’ S MANUAL for main board.

• Cable set for IDE, Floppy devices.

• Diskette or CD for main board Utility.

The main board contains sensitive electric components, which can be easily
damaged by static electricity, so the main board should be left in its original
packing until it is installed.

Unpacking and installation should be done on a grounded anti-static mat.
The operator should be wearing an anti static wristband, grounded at the
same point as the anti-static mat.

Inspect the main board carton for obvious damage. Shipping and handling
may cause damage to your board. Be sure there are no shipping and
handling damages on the board before proceeding.

After opening the main board carton, extract the system board and place it
only on a grounded anti-static surface component side up. Again inspect the
board for damage. Press down on all of the socket IC's to make sure that
they are properly seated. Do this only on with the board placed on a firm flat
surface.

3.4. DRAM INSTALLATION

The main board can be installed with 8 / 16 / 32 / 64 / 128 / 256 MB 168
pins DIMM module DRAM, and the DRAM speed must be 67~100 MHz for
SDRAM when system bus speed is set to 66MHz. When system bus speed
is set to 100MHz, 100MHz SDRAM is required. The DRAM memory system
on main board consists of bank 0, 1, 2 & bank 3.

Since 168 pins DIMM module is 64 bits width, therefore 1 piece of DIMM
module may match a 64 bits system. The total memory size is 8 MB ~1GB
SDRAM. The DRAM installation position refer to Figure 3.1, and notice the
Pin 1 of DIMM module must match with the Pin 1 of DIMM socket. Insert the
DRAM DIMM module into the DIMM socket at Vertical angle. If there is a
wrong direction of Pin 1, the DRAM DIMM module could not be inserted into
socket completely.

3.5. CPU SPEED SETUP

The system bus speed can be set to 66 / 100MHz form the DIP SWITCH
(SW). The user can change the DIP SWITCH selection to set up the CPU
speed for different processors.

metal surface when the CPU is installed onto main board.

3.6. CMOS RTC & ISA CFG CMOS SRAM

There're RTC & CMOS SRAM on board; they have a power supply from
external battery to keep the DATA inviolate & effective. The RTC is a REAL­TIME CLOCK device, which provides the DATE & TIME to system. The
CMOS SRAM is used for keeping the information of system configuration, so
the system can automatically boot OS every time. Since the lifetime of
internal battery is 5 years, the user can change a new Battery to replace old
one after it cannot work.

M Danger of explosion if battery is incorrectly replaced.

M Replace only with the same or equivalent type recommended by the

manufacturer.

M Dispose of used batteries according to the manufacturer’ s instructions.

3.7. SPEAKER CONNECTOR INSTALLATION

There is a speaker in AT system for sound purpose. The 4 - Pins connector

SPKR is used to connect speaker. Anode connects +, Cathode connects −.

3.8. HARDWARE RESET SWITCH CONNECTOR INSTALLATION

The RESET switch on panel provides users with HARDWARE RESET
function. The system will do a cold start after the RESET switch is pushed
and released by user. The RESET switch is a 2 PIN connector and should be
installed to RST on main board.

3.9. POWER LED CONNECTOR INSTALLATION

System has Power LED lamp on the panel of case. The Power LED will light
on off or flash to indicate which step on the system. The connector should be
connected to PWR of main board in correct direction.

3.10. IDE & ATAPI DEVICE INSTALLATION

There are two-Enhanced PCI IDE ports (IDE1, IDE2) on board, which
following ATAPI standard SPEC. Any one IDE port can connected to two
ATAPI devices (IDE Hard Disk, CD-ROM & Tape Driver), so total four ATAPI
devices can exist in a system. The HD is the active LED port for ATAPI
devices.

3.11. PERIPHERAL DEVICE INSTALLATION

After the I/O device installation and jumpers setup, the main board can be
mounted into the case and fixed by screw. To complete the main board
installation, the peripheral device could be installed now. The basic system
needs a display interface card. If the PCI - Bus device is to be installed in the
system, any one of four PCI - Bus slots can be used.

3.12. KEYBOARD & PS/2 MOUSE INSTALLATION

3-8

Hardware Installation

The main board supports PS/2 Mouse. The BIOS will auto detect whether the
PS/2 Mouse is installed or not & assign IRQ12 for PS/2 Mouse port if it is
installed. After installing the peripheral device, the user should check
everything again, and prepare to power-on the system.

3-9

Suspend To RAM Installation

IV. Suspend to RAM Installation
A.1 Introduce STR function:

Suspend-to-RAM (STR) is a Windows 98 ACPI sleep mode function.
When
recovering from STR (S3) sleep mode, the system is able, in just a few
seconds, to retrieve the last “state” of the system before it went to sleep
and
recover to that state. The “state” is stored in memory (RAM) before the
system goes to sleep. During STR sleep mode, your system uses only
enough energy to maintain critical information and system functions,
primarily the system state and the ability to recognize various “wake up”
triggers or signals, respectively.

A.2 STR function Installation

Please use the following steps to complete the STR function installation.

Step-By-Step Setup

Step 1:

To utilize the STR function, the system must be in Windows 98 ACPI mode.

Putting Windows 98 into ACPI mode is fairly easy.

There are two ways to accomplish this:

1. Setup with Windows 98 CD:

A. Insert the Windows 98 CD into your CD-ROM drive, select Start, and

then Run.

B. Type (without quotes) “D:\setup /p j” in the window provided. Hit the

enter key or click OK.
C. After setup completes, remove the CD, and reboot your system
(This manual assumes that your CD-ROM device drive letter is D:).

V. Introduce Dual BIOS

A. What is Dual BIOS Technology?

Dual BIOS means that there are two system BIOS (ROM) on the
motherboard, one is the Main BIOS and the other is Backup BIOS.
Under the normal circumstances, the system works on the Main BIOS. If
the Main BIOS is corrupted or damaged, the Backup BIOS can take over
while the system is powered on. This means that your PC will still be
able to run stably as if nothing has happened in your BIOS.

GIGABYTE Technology is pleased to introduce DualBIOS technology, a hot
spare for your system BIOS. This newest “Value-added” feature, in a long
series of innovations from GIGABYTE, is available on GA-BX2000
motherboard. Future GIGABYTE motherboards will also incorporate this
innovation.

Technology FAQ

What’ s DualBIOS?

On GIGABYTE motherboards with DualBIOS there are physically two BIOS
chips. For simplicity we’ ll call one your “ Main BIOS” and the other we’ ll call
your “Backup” BIOS (your “ hot spare”). If your Main BIOS fails, the Backup
BIOS almost automatically takes over on your next system boot. Almost
automatically and with virtually zero down time! Whether the problem is a
failure in flashing your BIOS or a virus or a catastrophic failure of the Main
BIOS chip, the result is the same - the Backup BIOS backs you up, almost
automatically.

I. Q: What is DualBIOSTM technology?
Answer:

DualBIOS technology is a patented technology from Giga-Byte Technology.
The concept of this technology is based on the redundancy and fault
tolerance theory. DualBIOSTM technology simply means there are two
system BIOSes (ROM) integrated onto the motherboard. One is a main
BIOS, and the other is a backup BIOS. The mainboard will operate normally
with the main BIOS, however, if the main BIOS is corrupt or damaged for
various reasons, the backup BIOS will be automatically used when the
system powered-On. Your PC will operate as before the main BIOS was
damaged, and is completely transparent to the user.

II. Q: Why does anyone need a motherboard with DualBIOS

TM

technology?
Answer:

In today’ s systems there are more and more BIOS failures. The most
common reasons are virus attacks, BIOS upgrade failures, and/or
deterioration of the BIOS (ROM) chip itself.

1. New computer viruses are being found that attack and destroy the
system BIOS. They may corrupt your BIOS code, causing your PC to be
unstable or even not boot normally.

2. BIOS data will be corrupted if a power loss/surge occurs, or if a user
resets the system, or if the power button is pressed during the process
of performing a system BIOS upgrade.

3. If a user mistakenly updates their mainboard with the incorrect BIOS
file, then the system may not be able to boot correctly. This may cause
the PC system hang in operation or during boot.

4. A flash ROM's life cycle is limited according to electronic characteristics.
The modern PC utilizes the Plug and Play BIOS, and is updated
regularly. If a user changes peripherals often, there is a slight chance of
damage to the flash ROM.

With Giga-Byte Technology’ s patented DualBIOSTM technology you can
reduce the possibility of hangs during system boot up, and/or loss BIOS data
due to above reasons. This new technology will eliminate valuable system
down time and costly repair bills cause by BIOS failures.

43

Introduce Dual BIOS

III. Q: How does DualBIOSTM technology work?
Answer:

1. DualBIOSTM technology provides a wide range of protection during the

boot up procedure. It protects your BIOS during system POST, ESCD
update, and even all the way to PNP detection/assignment.

2. DualBIOSTM provides automatic recovery for the BIOS. When the first

BIOS used during boot up does not complete or if a BIOS checksum error
occurs, boot-up is still possible. In the DualBIOSTM utility, the "Auto
Recovery" option will guarantee that if either the main BIOS or backup
BIOS is corrupted, the DualBIOSTM technology will use the good BIOS
and correct the wrong BIOS automatically.

3. DualBIOSTM provides manual recovery for the BIOS. DualBIOS

TM

technology contains a built-in flash utility, which can flash your system
BIOS from backup to main and/or visa versa. There is no need for an OS­dependent flash utility program.

4. DualBIOSTM contains a one-way flash utility. The built-in one-way flash

utility will ensure that the corrupt BIOS is not mistaken as the good BIOS
during recovery and that the correct BIOS (main vs. backup) will be
flashed. This will prevent the good BIOS from being flashed.

IV. Q: Who Needs DualBIOSTM technology?
Answer:

1. Every user should have DualBIOSTM technology due to the advancement

of computer viruses.
Everyday, there are new BIOS-type viruses discovered that will destroy
your system BIOS. Most commercial products on the market do not have
solutions to guard against this type of virus intrusion. The DualBIOS
technology will provide a state-of-the-art solution to protect your PC:
Case I.) Vicious computer viruses may wipe out your entire system BIOS.
With a conventional single system BIOS PC, the PC will not be functional
until it is sent for repairs.
Case II.) If the "Auto Recovery" option is enabled in the DualBIOSTM utility,
and if a virus corrupts your system BIOS, the backup BIOS will
automatically reboot the system and correct the main BIOS.
Case III.) A user may override booting from the main system BIOS. The
DualBIOSTM utility may be entered to manually change the boot sequence
to boot from the backup BIOS.

TM

44

BX2000

2. During or after a BIOS upgrade, if DualBIOSTM detects that the main BIOS
is corrupt, the backup BIOS will take over the boot-up process
automatically. Moreover, it will verify the main and backup BIOS
checksums when booting-up. DualBIOSTM technology examines the
checksum of the main and backup BIOS while the system is powered on
to guarantee your BIOS operates properly.

3. Power Users will have the advantage of having two BIOS versions on their
mainboard. The benefit is being able to select either version BIOS to suit
the performance system needs.

4. Flexibility for high-end desktop PCs and workstation/servers. In the
DualBIOSTM utility, the option can be set, "Halt On When BIOS Defects,"
to be enabled to halt your system with a warning message that the main
BIOS has been corrupted. Most workstation/servers require constant
operation to guarantee services have not been interrupted. In this
situation, the "Halt On When BIOS Defects" message may be disabled to
avoid system pauses during normal booting. Another advantage you gain
from Giga-Byte’ s DualBIOSTM technology is the ability to upgrade from
dual 2 Mbit BIOS to dual 4 Mbit BIOS in the future if extra BIOS storage is
need.
