Gigabyte announces @BIOS

Windows BIOS live update utility

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.

EasyTune

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 is-

sues in computer field. But have many users ever

tried it? The answer is probably "no". Because

"Overclock" is thought to be very difficult and in-

cludes 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 hardware 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 windows 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.
