I did mention that all but *broken* drives would obey the jumpers.
There's no sane reason for it to work any other way.  The jumpers select
whether the drive is master/single/slave/cable-select.  If the jumpers
weren't the controlling factor, you wouldn't have those options, nor be
able to make them.

A drive would have to be seriously broken to override or ignore jumpers,
it'd give you NO way to set what you want.
