Yeap, this is how IDE deals with polling commands but I'm not sure how

enlighten me here?
Simple answer: Badly. If you've got the IRQ shared it mucks up the
behaviour of the other device especially when its doing PIO.
OIC, I've been thinking I must be missing something but it's just
supposed to work that way. Doesn't sound too attractive. :-(
Yeah. It's ugly -- designed for use at boot time only, really.
As I've said a few times here, the IDE Subsystem was designed/implemented
*pre-hotplug*, and though it does work well most of the time,
the world has moved on.
