Well, I am only guessing about this after the fact, but it looks like
the 5000P which is a server chipset, and is the one in the SuperMicro
X7 systems, is the one with I/OAT.
I went to Intel's site and I gotta admit, I dont see an easy way to
tell this.
Have to talk to some sales/marketing types though, not some
lowly engineer like me :)
Cheers,
Jack
