VIA VT8237 Serial ATA RAID Introduction
A-11
Duplicate Critical RAID 1 Array
When booting up the system, BIOS will detect if the RAID 1 array has
any inconsistencies between user data and backup data. If BIOS detects any
inconsistencies, the status of the disk array will be marked as critical, and BIOS
will prompt the user to duplicate the RAID 1 in order to ensure the backup data
consistency with the user data.
If user selects Continue to boot, it will enable duplicating the array after
booting into OS.
