BIOS Flash
MCU External Flash
•
BIOS Flash: Master ROM for BIOS
•
MCU External Flash: Slave ROM for backup BIOS
In case the motherboard fails to boot, it will run BIOS self diagnostics to
verify the BIOS status on the master ROM. If problem is detected on the
BIOS, then the recovery process will automatically start to load the backup
BIOS from the slave ROM. The whole process will take about 2~3 minutes
where a BIOS recovery status LED will show the recovery status as
described below:
•
The LED blinks fast to indicate erasing data from the master ROM.
•
The LED blinks slowly to indicate the MCU is writing system backup
BIOS from the slave ROM to the master one.
