YES ! For one very simply reason. Both controller will want to use
the same port, same BIOS address etc etc. and they will fight with
one another. Likewise for the ESDI controller.

So far, the only thing that I know which co-exist with other controller
is the SCSI controller. A friend of mine just added a SCSI drive to
his system with existing ESDI drive.
