English III. Q: How does DualBIOSTM technology work? Answer: 1. DualBIOSTM technology provides a wide range of protection during the boot up procedure. It protects your BIOS during system POST, ESCD update, and e ven all the way to PNP detection/assignment. 2. DualBIOSTM 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 DualBIOSTM utility, the "Auto Recovery"option will guarantee that if either the main BIOS or backup BIOS is corrupted, the DualBIOSTM technology will use the good BIOS and correct the wrong BIOS automatically. 3. DualBIOSTM provides manual recovery for the BIOS. DualBIOSTM 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. DualBIOSTM 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. ba ckup) will be fla shed. This will p revent the good BIOS from being flashed. IV. Q: Who Needs DualBIOSTM technology? Answer: 1. Every user should have DualBIOSTM technology due to the advancementof computer viruses. Everyda y, there are n ew BIOS-type viruses discovered that will destroy your system BIOS. Most commercial products on the market do not have solutions to guard against this typ e of virus intrusion. The Du alBIOSTM techn ology 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 conve ntional single system BIOS PC, the PC will not be functiona l until it is sen t for repairs. Case II.) If the "Auto Recovery"option is enabled in the DualBIOSTM 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 DualBIOSTM - 79 - Technical Reference
