this isn't really "classic" per se, but... I grabbed a performa 636cd, w/ a 500mb ide drive. being curious i ripped out the 1-connector ide cable and connected a 2-connector; the mac ide quantum (which specifically says "apple" on it...) was set as master, and i popped a seagate on as a slave. no boot unless i popped in the mac disk tools. if i take off the 2nd ide drive, it boots. being a total mac idiot, is it even possible to use a ATA ide drive on a mac? or is there something else to this that i'm missing? any help would be gratefully appreciated. thanks. -Eric
