You're right in saying that there's no dedicated C, D, Master
or Slave on an IDE controller itself. I'm sorry if I gave the
impression that the jumpers for master/slave were anywhere but
on the IDE drive itself.
Regarding your second point about the order in which devices
are connected to the IDE ribbon cable, I seem to recall having
problems with this, particularly on several older machines. It
could very well be that I'm having a senior moment though (I'll
be 42 next month, so I'm officially a geezer now), and confusing
floppy controller errors with hard drive errors. More telling is
that I'm probably recalling errors I've had with pre-IDE drives.
In any case, the habit of putting the first drive in line first
is hard-wired in me now. You are correct though; I mean, on an
IDE drive, the controller is built into the drive itself, so
cable order shouldn't matter. Thanks for setting me straight.
