Q: What is the dual boot protection mechanism on ASUSTOR NAS?

ASUSTOR NAS devices use two boot partitions in the internal flash memory to provide boot protection.

During startup, the system verifies the primary boot partition. If checksum verification fails, the NAS can load the secondary boot partition to prevent boot failure.

This mechanism is supported on both ARM-based and x86-based ASUSTOR NAS devices.
