MULTI BIOS SWITCH: Multi BIOS Switch

This mainboard has two built-in BIOS ROMs (Labeled A and B, default BIOS ROM is A). If one is crashed, you can shift to the other for booting by sliding the switch. In addition, these two BIOS ROMs do not have the Auto Recovery feature, you need to maintain or update the BIOS version by yourself.

BIOS recovery using the M-flash utility:

1.Ensure that the system is switched off.

2.Boot up the system with the operational BIOS ROM by switching the Multi-BIOS switch.

3.Enter the BIOS setup → Utilities → M-Flash → Save BIOS to storage and then save the file to a bootable USB pen drive (root folder).

4.Switch back to the BIOS ROM that needs to be recovered.

5.Choose “Select one file to update BIOS” and recover the BIOS ROM with the file saved in the USB pen drive.

Important

Do not use the BIOS switch when system is booting up.
