To reset hard disk drives to non-RAID, do the following:
1. Enter the Intel RSTe configuration utility. See "Entering the Intel RSTe configuration utility" on page 44.
2. Press the up and down arrow keys to select Reset Disks to Non-RAID. Press Enter to enter the
RESET RAID DATA window.
3. Use the up and down arrow keys and the space key to mark individual hard disk drive to be reset,
and then press Enter to complete the selection.
4. When prompted, press Y to confirm the reset action.
5. If the hard disk drive you reset is part of a RAID volume, the computer might detect that the RAID volume
is degraded. In this case, you are prompted to select a hard disk drive to initiate a rebuild process.
