No, what I meant by "industry standard" parts were the drives. Since
there's virtually no room for creativity in the host side of interface
as far as the vanilla IDE is concerned, I thought it's got to be
something on the drive itself if Apple had decided to deviate from the
ANSI standard.

That's exactly my point.
