N400 Pro2 / N400 Series Motherboard

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 DualBIOS

™

 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.

This new technology will eliminate valuable system down time and costly repair bills cause by
BIOS failures.

1. DualBIOS

™

 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 detec-
tion/assignment.

2. DualBIOS

™

 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
DualBIOS

™

 utility, the "Auto Recovery" option will guarantee that if either the main BIOS or

backup BIOS is corrupted, the DualBIOS

™

 technology will use the good BIOS and correct the

wrong BIOS automatically.

3. DualBIOS

™

 provides manual recovery for the BIOS. DualBIOS

™

 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. DualBIOS

™

 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.
