 XT-IDE? What's that? I didn't know that there was
an XT compatible IDE
 controller, except a few rare and expensive ones. 
 
It's 8 bit IDE.
At the time, they were neither rare, nor very expensive.
If you waited until now to buy one, then you may be outa luck. 
Sometimes called XTA; these drives could do 8 bit data transfers--i.e.,
they actually paid attention to IOCS16\.
