Model: KT7E / KT7E-RAID

Version: ALL

Note: The RAID function is for KT7E-RAID 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 KT7E-RAID BIOS!!!

When you upgrade bios from ZH / ZT to 3C / 3R / 4A / 64 / 7N, we highly recommend you backup your system and data to an independent storage device first. New HPT 1.11.0402 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 HPT370 setup screen and do "Duplicate Mirror Disk " to recover RAID system.
