I am attempting to add a third hard drive to my NEC Powermate I AT clone.

I have a WD1003-WAH hard disk controller with two hard drives attached.
I also have a FileCard 20  with a WDC 60-000227-01 controller.

I have configured the 1003 as controller 1, and configured the 60-000227 as
the second controller at BIOS address CA00. I can't get it to recognize the
drives. When I try to boot, the D drive on the 1003 and the Drive on the
File Card start *chirping* and everything seems to stop. I suspect a Port
conflict or some such problem. I don't quite understand completely how
the system addresses the drives on the first and second controllers. Do
they share ports/per/controller? I can configure the controller on the
Hard Card for ports 320 or 324 Hex.

I don't have any tech sheets on the 1003, so i am not sure exactly how it
is configured.

Anyone else accomplish this? Is it a futile effort? I'd really like to use
this filecard for *slow* storage.

Thanks
