USER MANUAL GA-7VAX1394 GIGABYTE

When you installing AGP card, please make sure the following notice is fully understood and practiced. If your AGP card has "AGP 4X/8X(1.5V) notch"(show below), please make sure your AGP cardis AGP 4X/8X(1.5V). ACP 2x noteh / AGP4X/ÆEX notch Caution: AGP 2X(3.3V) card is not supported by VIA® KT400. You might experience system unable to boot up normally. Please insert an AGP 4X/8X(1.5V) card Example 1: Diamond Vipper V770 golden finger is compatible with 2X/4X mode AGP slot. It can be switched between AGP 2X(3.3V) or 4X (1.5V) mode by adjusting the jumper. The factory default for this card is 2X(3.3V). The GA-7VAX/ GA-7VAX1394 / GA-7VAXP / GA-7VAXP Ultra (or any AGP 4X only) motherboards might not function propeny, if you installthis card without switching the jumper to4X(1.5) mode init. Example 2: Some ATi Rage 128 Pro graphics cards made by “Power Color”, the graphics card manufacturer & some SiS 305 cards, their golden finger is compatible with 2X(3.3V)/4X(1.5V) mode AGP slot, but they support 2X(3.3V) only. The GA-7VAX / GA-TVAX1394/ GA-7VAXP 1 GA-7VAXP Ultra (or any AGP 4X only) motherboards mightnot function properly, lfyou install this cardin it. Note : Although Gigabyte's AG32S(G) graphics card is based on ATiRage 128 Pro chip, the design of AG32S(G) is compliance With AGP 4X(1.5V) specification. Therefore, AG32S (G)will work fine with VIA® KT400 based motherboards. Before you install PCIcards, please remove the Dual BIOS label from PCI slots ifthere is one.

This new est “Value-added” feature, in a long series ofinnovañons from GIGABYTE, is available on GA-6OXET Series motherboard. Future GIGAB YTE motherboards will also incorporate this innovation. What'sDualBIOSW? On GIGABYTE motherboards wGith 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"). lfyour Main BIOS fails, the Backup BIOS almost automatically takes over on your next System boot Almost automatically and with virually zero down ime! Whether the problem is a failure in flashing y our 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. KT400 Series Motherboard -70-

1.Q: Whatis DualBlOS "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. DualB 10S'" 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, ifthe 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 trans parent to the user. Il. Q: Whydoes anyone need a motherboard with DualBIOST" 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 he 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 corupted if a power loss/surge occurs, or if a user resets the sy stem,

orifthe power button is pressed during the process of performing a system BIOS upgrade.

3. lfa user mistakeniy updates their mainboard with the incorrect BIOS fle, then the

system may not be able to boot correct. This may cause the PC system hang in operation or during boot.

4. Aflash ROM's life cycleis limited according to electronic characteristics. The modem

PC uülizes 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-By te Technology's patented DualB1OST" technology you can reduce the possibility ofhangs during system boot up, and/or loss BIOS data due to above reasons. This new technology will eliminate valuable system down time and costiy repair bills cause by BIOS failures. -71- Technical Reference

111. Q: How does DualBIOS technology work?

DualB1OST" technology provides a wide range of protection during the boot up procedure. lt protects your BIOS during system POST, ESCD update, and even all the way to PNP detecton/assignment DualBIOST" provides automatic recovery for the BIOS. When the first BIOS used during boot up does not complete or ifa BIOS checksum error occurs, boot-up is still possible. In the DualBIOST" utility, the “Auto Recovery” opüon will guarantee that if either the main BIOS or backup BIOS is corupted, the DualBlOST“ technology will use the good BIOS and correct the wrong BIOS automañcally DualBlOS"" provides manual recovery for tre BIOS. DualBlOS'" technology contains a built-in flash uïlity, which can flash your system BIOS from backup to main and/or visa versa. There is no need for an OS-dependent fash utility program. DualBIOST" contains a one-way flash utlity. The built-in one-w ay 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 fashed. This will prevent the good BIOS from being flashed.

Every user should have DualB 1OST" 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 solufons to guard against this type of virus intrusion. The DualBIOST" technology will provide a state-ofthe-art solution to protect your PC: Case |.) 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 Il.) If the “Auto Recovery” opfon is enabled in the DualBlOST# utility, and ifa virus corupts your system BIOS, the backup BIOS will automaïcally reboot the system and correct the main BIOS. Case lil) A usermay overtide bootng from îne main system B10S. The DualB10 S TM KT400 Series Motherboard -72-

uflity may be entered to manually change the boot sequence to boot from the backup BIOS.

2. During or afer a BIOS upgrade, if DualBIOS'" detects that he main BIOS is corrupt, the

backup BIOS will take over the bootup process automañcally. Moreover, itwill verify the main and backup BIOS checksums when booting-up. DualBlOST" technology examines the checksum ofthe main and backup BIOS while the system is powered on to guarantee your BIOS operates properly.

3. Power Users will have the advantage of hav ing two BIOS versions on their mainboard.

Thebeneît is being able to select either version BIOS to suit the perfomance system needs.

4. Flexibility for high-end desktop PCs and workstation/servers. In the DualBIOST“ utlity,

the option can be set, “H alt On When BIOS Defects,” to be enabled to halt y our system with awarning message thatthe main BIOS has been corrupted. Most w orkstation/servers require constant operafon 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 adv antage y ou gain from Giga-Byte's DualB 10 ST" 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. -73- Technical Reference

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 every thing is different because of a Win- dows based overclocking utility "Easy Tune 4" -announced by Gigabyte. This windows based utility has totally changed the gaming rule of"Overclock". This is the first windows based overclocking uility is suitable for both normal and power users. U sers can choose either "Easy Mode" or "Ad- vanced Mode" for overclocking at their convenience. For users who choose "Easy Mode”, they just need to click "Auto Opümize" to have autoed and immediate CPU ov erclocking. This sofware will then overdrive CPU speed automañcally 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 l'AGP / Memory working frequency in small increments to get ulimate system performance. lt oper- ates in coordination with Gigabyte motherboards. Besides, it is different from other traditional over- clocking methods, Easy Tune 4 doesn't require users to change neither BIOS nor hardware sw itch/ jumper setfng; on the other hand, they can do "Overclock" at easy step . Therefore, this is a safer way for "Overclock" as nothing is changed on sofware or hardware. lfuser runs Easy Tune 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 Easy Tune 4, user can "Save" this setting and "Load" itin nexttime. Obviously, Gigaby te Easy Tune 4 has already turned the "Overclock" technology toward to a newer generaon. This wonderful sofware is now free bundied in Gigabyte motherboard attached in driver C D. Users may make a test drive of "Easy Tune 4" to find out more amazing features by themselves. *Some Gigabyte products are notfully supported by Easy Tune 4. Please find the products sup- ported list in the web site. “Any "Overclocking action" is atusers risk, Gigaby te Technology will not be responsible for any damage or instability to your processor, motherboard, or any other components. -77- Technical Reference
