True, but I didn=92t say that the chip wasn=92t interesting. What I = said is that it=92s not that attractive (to the real market for these: = micro servers). The dual 10Gig Ethernet and 8 SATA 3.0 ports are interesting. You = won=92t get that with a C2K system at 25W TDP, (4 x GigE that can run at = 2.5Gbps per port, and 2 SATA 3.0 ports currently) but Intel owns IP for = both, so if that becomes a differentiator for design wins, I=92d expect = a future variant to cover. But by all means, port FreeBSD to it. Perhaps it can be the = long-desired =93reference platform=94 to bring ARM into a =93Tier 1=94 = architecture status. Jim
