That's why, to be on the safe side, I bought an MB with both SATA and PATA drives - still 2 IDE channels like in good old times :-). Regarding JACK + ecasosund - do you really need JACK in such a case ? I think that ecasound supports ALSA directly, and it can act as a mixer, so why do you need JACK in the first place - if I'm right about ALSA support ?
