9. How does DualBIOS technology work Answer 1 DualBIOS technology provides a wide range of protection during the bootup procedure It protects your BIOS during system POST ESCD update and even all the way to PNP detection assignment DualBIOS provides automatic recovery for the BIOS When the first BIOS used during bootup does notcomplete or ifa 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 DualBIOS provides manual recovery for the BIOS DualBIOS technology contains a builtin flash utility which can flash your system BIOS from backup to main and or visa versa There is no need for an OS dependent fash utility program DualBIOS contains a one way flash utility The builtin one way flash utility will ensure thatthe corrupt BIOS is not mistaken as the good BIOS during recovery and thatthe correct BIOS main vs backup will be flashed This will preventthe good BIOS from being flashed IV Q Who Needs DualBIOS technology Answer 1 Every user should have DualBIOS technology due to the advancementof computer viruses Everyday there are new BIOS type viruses discovered that will destroy your system BIOS Most commercial products on the market do nothave solutions to guard against this ty
