How can one tell before purchase which machines/chipsets have I/OAT?

We just bought a pair of Dell 2950s with a "5000X" Chipset
(8086:25c0), and there is no I/OAT DMA engine that I can see (no
device 8086:1a38).

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
