Dual BIOS Introduction

Dual BIOS Introduction (Optional) 

A. What is Dual BIOS Technology? 

 Dual BIOS means that there are two system BIOS (ROM) on the motherboard, one is the 

Main BIOS and the other is Backup BIOS. Under the normal circumstances, the system 
works on the Main BIOS. If the Main BIOS is corrupted or damaged, the Backup BIOS can 
take over while the system is powered on. This means that your PC will still be able to run 
stably as if nothing has happened in your BIOS.
