Introduce Dual BIOS

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.

DualBIOS

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 DualBIOSTM?

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.

47

Introduce Dual BIOS

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.

48

6GXDW

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

49

Introduce Dual BIOS

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.

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. 32-bits
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. HARDWARE INSTALLATION

3.1. UNPACKING

The mainboard package should contain the following:

• The 6GXDW mainboard.

• The Retention Mechanism & Attach Mount

• USER'S MANUALS for mainboard & SCSI device.

• Adaptec User’ s Guide.

• Cable set for IDE, Floppy, SCSI devices.

• Diskettes and CD for Mainboard Utility.(If you want to use LDCM to view

dual CPU Health, please run Patch file.)

• External LVD SCSI port adapter.

The mainboard contains sensitive electric components, which can be easily
damaged by static electricity, so the mainboard 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 mainboard 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 mainboard 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.

damaged by static electricity, so users must keep it away from 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.

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. SCSI DEVICE INSTALLATION

There are two ULTRA II SCSI channels on-board which both channel A and B
have 68-pin Ultra II SCSI ports for Ultra Wide and Ultra II SCSI devices.
Channel B has one 50-pin 8bit SCSI port for Ultra SCSI devices. Total of 30
SCSI devices (15 devices per channel) can exist within one system. The
termination of the channel A and channel B can be adjusted from the
Integrated Peripherals of the CMOS SETUP MENU. The termination of
channel A can be set to “Enabled” or “Disabled”. The termination of channel B
can be set to ”Both”, ”High Byte” ,“Low Byte”, or “None” for those types of the
SCSI devices which being connected to the SCSI ports to ensure proper
functionality.
