We have a X12DDW-A6 with Intel premium VROC key, and in GRAID website, it shows that it is possible to set up VROC with SED.

This was all written for Intel BIOS, not AMI. Can you assist us with getting this completed?
Intel standard release of VROC does not support SED drives. You can only setup SED drive as individual drive.
