I don't believe that is true; any ESDI controller

ESDI controller was what I used on some of the Maxtor ESDI drives with
no problems. I do not know if changing the controller brand would
require another low-level format for the drive to work properly. The
controller cards (at least for the ones I used) have the formatting
routines built into the BIOS and I *think* they are accessed in the same
way as XT HD controller cards, i.e. debug g=C006 (?).
Back when the cost of SCSI drives was dear and MFM had limited
capacity, I picked up a couple of refurbished ESDI drives and an Everex
EV-348 controller (still have it). It was more or less a drop in
replacment for a 16-bit ISA MFM controller, with an on board BIOS and
support for 2 floppy and 2 hard drives.

Default BIOS address was C8000h and could be disabled.
