the problem here is that it's got a SATA drive and there's no SATA driver for it on the XP install.. if you REALLY want xp on it, you'll need to goto the mobo manufacturers site and get their SATA drive and embed it onto a windows xp disk.. theres info on the net about this.. i've got the same problem w/ my hp.. but after turning a bunch of shit off in vista, its actually not that bad..

HOWEVER, i have had some midi timing problems w/ ableton.. :-(
