IV. Q: Who Needs DualBIOS TM technology?
Answer:
1. Every user should have DualBIOS TM 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
TM 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
TM 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
TM
III. Q: How does DualBIOS TM technology work?
Answer:
1. DualBIOS TM 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 TM 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
TM utility, the “Auto Recovery” option will guarantee that if either the main
BIOS or backup BIOS is corrupted, the DualBIOS TM technology will use the good BIOS
and correct the wrong BIOS automatically.
3. DualBIOS TM provides manual recovery for the BIOS. DualBIOS TM 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 TM 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.
