You most probably can't change the IO address on _any_ IDE "controller"
since these so called "controllers" are only a bunch of bus drivers or
latches or whatever, don't know exactly.
The real controller is an integral part of your disk drive - hence the
trouble with two drives from different manufacturers, master/slave mode
settings and the like.
Look for some way to set the disk drive into "master only" mode, or
"primary address" or whatever it may be called. If there is no such
option - get a different drive :-(
