Ive left messages for Tyan and sent emails and have gotten NO response in several weeks. Not a good way to foster trust! Im just trying to get a simple question answered which I could not find on the website. What is the difference (are the differences) between the S2469 K7X Pro with Green PCI socket and the boards without the green PCI socket (all brown White PCI sockets)? Why the Green PCI socket? Is that board the same as the other K7X pro boards? We have several racks of the K7X PRO 's running, and Id like to know more about what we have - feature wise and spec. wise. thanks
