MULTI BIOS SWITCH1: Multi-BIOS Switch
This motherboard 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 → M-Flash → Save BIOS to storage and then save the file to
a bootable USB drive disk (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 drive disk.
Important
Do not use the Multi-BIOS switch when system is booting up.
