Two BIOS Chips, Dual Protection!

The integrated Dual BIOS design improves safety and convenience by allowing enthusiasts to manually switch between two different BIOS ROMs when one is corrupted by improper overclocking, virus attack, or HW failure.

How to Use Dual BIOS?

  1. 1. The Dual BIOS allows you to choose one of the BIOS ROMs (ROM1/ROM2) for booting up.
  2. 2. If you want to flash BIOS ROM, please make sure the Dual BIOS switch is set to the BIOS ROM which you want to update.
  3. 3. The failed BIOS can be updated by using BIOSTAR BIOS Flasher or BIOSTAR BIOS Update Utility.

Do not use the Dual BIOS switch during a BIOS update since it will result to the corruption of BIOS ROMs.
