I got may replies (Thank you!) and the solution I used was to jumper my Conner disk correctly to work as master (Sorry, but I had no info on the drive). Here is a table on how to jumper Conner disks that worked for my CP30104: >From torsten@techfac.uni-bielefeld.de: > The jumper settings for one and two Conner drives (CP3504, 500MB > and CP3104, 100MB). If the jumpers on your drive are labelled as > below, you might try this one (no guarantee): > > CONFIGURATION HSP C/D DSP ACT > ------------- --- --- --- --- > One drive Off On Off On > Two drives > Master Off On On On > Slave Off Off Off On > > where "on" means to place the jumper and "off" to remove it. I didn't try to use two controllers, since the easy solution worked, but if someone else needs to do this, you need a controller where you can change the address space for the registers from 1F0 to 170, and you need to change the interrupt from the controller from IRQ 14 to for example IRQ 15, either by moving a jumper, if that is supported, or by soldering. Here is the layout of that part of the bus: >From rcd@eklektix.com Thu Sep 10 04:25:49 1992: > First, orientation: Looking down on the motherboard, with the rear panel > away from you - component sides of boards are to the right - the high- > numbered interrupts are on the secondary connectors (exist only on 16-bit > slots) which are nearer to you.

The unassigned IRQ's in the second group are 10, 11, 12, and 15. Thank you everybody that helped me with this!
