Yes, I think you're correct. I found a south bridge spec., http://www.tser.org/vt8231/vt8231.pdf, and I don't see a pin for driving an IDE RESET-.
Oh well, I suppose I either dike out RESET- from the IDE cable and wire it up to a serial or parallel port, or give up using a PC for the task and use a dedicated circuit.
Thanks for your help.
Ralph.
