It looks like over 1500 of you have viewed my post with no answers. I finally inquired with Intel and an engineer responded with to me in one day. Please see that response below, and thanks to Intel for the prompt and excellent response. I feel a little more secure now.
Thank you for contacting Intel Technical Support.
As we understand you would like to know if the RAID configuration on a system would be kept if there is a CMOS failure on the computer which may cause a change on the settings of the RAID configuration.
The configuration on how the RAID is set is saved on the metadata of the hard drives, so, if there is a CMOS failure that reverts the SATA mode from RAID to AHCI or IDE mode, you could be able to get into the BIOS and change back the SATA mode to RAID and then the RAID controller will be able to identify the metadata on the disks and continue working.
However, if the setting has been set to IDE or AHCI mode, you need to change it back to RAID mode before any change is done to any of the disks, otherwise the parity or information on the RAID cannot be restored.
