Yes, that's expected. Unfortunately not documented. Sorry.

You have to download the NPE microcode binary (exactly this missing file from 
the Intel download site). Here a link for the newest microcode (I have *not* 
tested with this microcode version):

Could be that you have to register to access this file though.
