 Introduction
Gigabyte announces @ BIOS
Windows BIOS live update utility
Have you ever updated BIOS by yourself? Or like
many other people, you just know what BIOS is,
but always hesitate to update it? Because you think
updating newest BIOS is unnecessary and actually
you dont know how to update it.
Maybe not like others, you are very experienced in BIOS updating and spend quite a lot of time
to do it. But of course you don’t like to do it too much. First, download different BIOS from website and
then switch the operating system to DOS mode. Secondly, use different flash utility to update BIOS.
The above process is not a interesting job. Besides, always be carefully to store the BIOS source
code correctly in your disks as if you update the wrong BIOS, it will be a nightmare.
Certainly, you wonder why motherboard vendors could not just do something right to save your
time and effort and save you from the lousy BIOS updating work? Here it comes! Now Gigabyte
announces @BIOS—the first Windows BIOS live update utility. This is a smart BIOS update
software. It could help you to download the BIOS from internetand update it. Not like the other BIOS
update software, its a Windows utility. With the help of @BIOS, BIOS updating is no more than a
click.
Besides, no matter which mainboard you are using, if its a Gigabytes product*, @BIOS help
you to maintain the BIOS. This utility could detect your correct mainboard model and help you to
choose the BIOS accordingly. It then downloads the BIOS from the nearest Gigabyte ftp site
automatically. There are several different choices; you could use Internet Update to download and
update your BIOS directly. Or you may want to keep a backup for your current BIOS, just choose
Save Current BIOS to save it first. You make a wise choice to use Gigabyte, and @BIOS update
your BIOS smartly. You are now worry free from updating wrong BIOS, and capable to maintain and
manage your BIOS easily. Again, Gigabytes innovative product erects a milestone in mainboard
industries.
For such a wonderful software, how much it costs? Impossible! Its free! Now, if you buy a
Gigabytes motherboard, you could find this amazing software in the attached driver CD. But please
remember, connected to internet at first, then you could have a internet BIOS update from your

 4 Introduction
Gigabyte announces EasyTuneTM 
 4
Windows based Overclocking utility
EasyTune 4 carries on the heritage so as to pave the way for future generations.
Overclock might be one of the most common issues
in computer field. But have many users ever tried it?
The answer is probably no. Because Overclock
is thought to be very difficult and includes a lot of
technical know-how, sometimes Overclock is even
considered as special skills found only in some
enthusiasts. But as to the experts in Overclock,
whats the truth? They may spend quite a lot of time
and money to study, try and use many different hard-
ware or BIOS tools to do Overclock. And even with these technologies, they still learn that its quite a
risk because the safety and stability of an Overclock system is unknown. Now everything is different
because of a Windows based overclocking utility EasyTune 4 --announced by Gigabyte. This win-
dows based utility has totally changed the gaming rule of Overclock. This is the first windows based
overclocking utility is suitable for both normal and power users. Users can choose either Easy Mode
or Advanced Mode for overclocking at their convenience. For users who choose Easy Mode, they
just need to click Auto Optimize to have autoed and immediate CPU overclocking. This software will
then overdrive CPU speed automatically with the result being shown in the control panel. If users prefer
Overclock by them, there is also another choice. Click Advanced Mode to enjoy sport drive class
Overclocking user interface. Advanced Mode, allows users to change the system bus / AGP /
Memory working frequency in small increments to get ultimate system performance. It operates in
coordination with Gigabyte motherboards. Besides, it is different from other traditional over-clocking
methods, EasyTune 4 doesnt require users to change neither BIOS nor hardware switch/ jumper setting;
on the other hand, they can do Overclock at easy step . Therefore, this is a safer way for Overclock
as nothing is changed on software or hardware. If user runs EasyTune 4 over systems limitation, the
biggest lost is only to restart the computer again and the side effect is then well controlled. Moreover, if one
well-performed system speed has been tested in EasyTune 4, user can Save this setting and Load
it in next time. Obviously, Gigabyte EasyTune 4 has already turned the Overclock technology toward
to a newer generation. This wonderful software is now free bundled in Gigabyte motherboard attached in
driver CD. Users may make a test drive of EasyTune 4 to find out more amazing features by
themselves.
*Some Gigabyte products are not fully supported by EasyTune 4. Please find the products supported list
in the web site.
*Any Overclocking action is at users risk, Gigabyte Technology will not be responsible for any
damage or instability to your processor, motherboard, or any other components.

							- 62 - GA-8KNXP Ultra-64 MotherboardEnglishFlash BIOS Method Introduction
Method 1: Dual BIOS /Q-Flash
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.
B.How to use Dual BIOS and Q-Flash Utility?
a. After power on the computer, pressing  immediately during POST (Power On Self Test) it will
allow you to enter Award BIOS CMOS SETUP, then press  to enter Flash utility.CMOS Setup Utility-Copyright (C) 1984-2004 Award Software}Standard CMOS Features

							Technical Reference- 65 -EnglishI. 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.DualBIOSTM
 Technology FAQ
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 this motherboard. Future GIGABYTE motherboards will also incorporate this
innovation.
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 well 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. 
						

							- 66 - GA-8KNXP Ultra-64 MotherboardEnglishIII. 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. DualBIOSTM
 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 OS-dependent 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. II. Q: Why does anyone need a motherboard with DualBIOSTM
 technology?
Answer:
In todays 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 ROMs 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.
