I'm under the impression it needs to be setup in the bios first.
if that does not work, then the next option is to install to a spare drive, setup the SRT, then re-install windows.
failing that, then I can only assume intel stuffed up with the system and so their is no option for doing what you want.
I've only read people talking about going down the same path as you want to, I do not expect it to be too complicated, but then it is new tech and intel might not want this to work for some reason.
