II. Q: Why does anyone need a motherboard with DualBIOS TM 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 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 TM 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.
I. Q: What is DualBIOS TM 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. DualBIOS TM 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.
