Hehe, as if reading your mind I ordered Tyan K8E today, and in case that won't work, i'll just put a pci raiser there and stuck an external SATA from silicon image or promise there :) I've heard from another person (thou have not seen it myself) that there was kind of the same problem (hanging sata) on an opteron-based machine. I was too late to ask the mb model thou, so this info is kind of useless, but just for statistical purposes I mention it here. > [Jeff, could you please say if this is a known problem?]
