More aboutwhat motherboard dual bios
Dual BIOS can help in several ways. If a BIOS update is interrupted or corrupted somehow like by power loss it will literally kill your motherboard. Also sometimes when overclocking a certain version of BIOS may be more stable than others. I have actually had a motherboard that was not stable with a newer BIOS version when overclocking and would start a reboot loop. Gigabyte's dual BIOS allwed me to revert to the older more stable version. In my opinion it's a necessary feature.
If the first "normal" flash BIOS is damaged, then a function built into the board checks to see if the BIOS starts correctly or not.
If BIOS does not start correctly, then the motherboard automatically switches over to the backup BIOS.
This gives you the possibility of overwriting the damaged flash BIOS and initiating a new startup process.
