  • Page 60 DualBIOS Technology FAQ GIGABYTE Technology is pleased to introduce DualBIOS technology, a hot spare for your system BIOS. This newness “Value-added” feature, in a long series of innovations from GIGABYTE, is available on GA-6CX7 motherboard. Future GIGABYTE motherboards will also incorporate this innovation.
  • Page 61 Dual BIOS Introduction I. Q: What is DualBIOS technology? Answer: DualBIOS technology is a patented technology from Giga-Byte Technology. The concept of this technology is based on the redundancy and fault tolerance theory. DualBIOS technology simply means there are two system BIOSes (ROM) integrated onto the motherboard. One is a main BIOS, and the other is a backup BIOS.
  • Page 62 6CX7 Motherboard III. Q: How does DualBIOS technology work? Answer: 1. DualBIOS 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.
  • Page 63 Dual BIOS Introduction 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.
