III. Q: How does DualBIOS ™ technology work?
Answer:
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 detection/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.
IV. Q: Who Needs DualBIOS ™ technology?
Answer:
This new technology will eliminate valuable system down time and costly repair bills cause by BIOS failures.
1. Every user should have DualBIOS ™ 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 solutions to guard against this type of virus intrusion. The DualBIOS
™
technology will provide a state-of-the-art solution to protect your PC:
Case I.) 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 II.) If the "Auto Recovery" option is enabled in the DualBIOS ™ utility, and if a virus corrupts your
system BIOS, the backup BIOS will automatically reboot the system and correct the main BIOS.
Case III.) A user may override booting from the main system BIOS. The DualBIOS ™ utility may be en-
tered to manually change the boot sequence to boot from the backup BIOS.
2. During or after a BIOS upgrade, if DualBIOS ™ detects that the main BIOS is corrupt, the backup BIOS
will take over the boot-up process automatically. Moreover, it will verify the main and backup BIOS
checksums when booting-up. DualBIOS
™ technology examines the checksum of the main and backup
BIOS while the system is powered on to guarantee your BIOS operates properly.
3. Power Users will have the advantage of having two BIOS versions on their mainboard. The benefit is
being able to select either version BIOS to suit the performance system needs.
4. Flexibility for high-end desktop PCs and workstation/servers. In the DualBIOS ™ utility, the
option can be set, "Halt On When BIOS Defects" to be enabled to halt your system with awarning
message that the main BIOS has been corrupted. Most workstation/servers require constant operation
to guarantee services have not been interrupted. In this situation, the "Halt On When BIOS Defects"
m e s s a g e m a y b e d i s a b l e d t o a v o i d s y s t e m p a u s e s d u r i n g n o r m a l b o o t i n g .
Another advantage you gain from Giga-Byte's DualBIOS
™ 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.
