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 v iruses 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 sy stem,
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 P lug 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 DualB IOS
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. DualB IOS 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 w ith 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 w ill operate as before the main
BIOS was damaged, and is completely transparent to the user.
