@ BIOS Introduction

English

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 don’t 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, it’s 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 it’s a Gigabyte’s 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, Gigabyte’s innovative product erects a milestone in mainboard

industries.

For such a wonderful software, how much it costs? Impossible! It’s free! Now, if you buy a

Gigabyte’s 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

Gigabyte @BIOS.

Easy Tune

4 Introduction

Gigabyte announces EasyTune

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",

what's 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 it's 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 doesn't 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 system's 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 user's risk, Gigabyte Technology will not be responsible for any

damage or instability to your processor, motherboard, or any other components.
