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 conven-
tional 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 entered 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" message may be disabled to avoid system pauses during normal booting.
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.
