Model: KR7A-133 / KR7A-133R

Note: The RAID function is for KR7A-133R only. This BIOS version is also for non RAID boards and HPT BIOS will be automatically disabled while RAID controller chip not detected.

!!! Attention for upgrading KR7A-133R BIOS!!!

When you upgrade bios from old version to 9N, we highly recommend you backup your system and data to an independent storage device first. New HPT 2.31 bios may corrupt original RAID configuration created on old bios occasionally. That means you may need to rebuild RAID configuration. If it happens, all the data on RAID-0 will be gone!

For RAID-1 user, please press "CTRL+H" to enter HPT372 setup screen and do "Duplicate Mirror Disk " to recover RAID system.
