I have a Precision 380 where the boot device was a RAID 1 mirror using the built in Intel Matrix RAID. I had to convert the RAID 1 volume back to two single drives with no RAID in order to do some recovery activity, and now I want to get those drives back to RAID 1. To my shock:
1) When I boot the Precision 380, I no longer get the Matrix Ctrl+I prompt, so I cannot make the drives RAID/AHCI or explicitly create mirrors. The drives are remaining AHCI non RAID drives and I cannot control it
2) When I get into the Intel Matrix Storage 6.x control application under Windows, there is no option there to let me create a RAID volume.
How do I force the BIOS utility to display an option to enter configuration, so I can get these drives back into RAID 1 configuration?
