GIGABYTE Ultra Durable motherboards feature GIGABYTE DualBIOS, an exclusive technology from GIGABYTE that protects arguably one of your PC's most crucial components, the BIOS. GIGABYTE DualBIOS means that your motherboard has both a 'Main BIOS' and a 'Backup BIOS', protecting users from BIOS failure due to virus, hardware malfunction, improper OC settings or power failure during the update process.
