MS-DOS woudn't find it, even if you cleared all IRQ and adress conflicts.

These is a real cheap solution:

3drvs110.zip (on an ftp site near you (simtel20 has it))
shareware $20

You'll need :

MFM controller (the good old one works)
with 1 or 2 MFM disks !

IDE controller with "moveable adresses"
(so you could set it up as secondary controller)
The readme in the zip file describes a seagate controller (ST07A or ST08A)
I tried it succesfully with an DTK PTI 227 (jumper settings are at home)
just - disable the floppy drive (if any)
     - move the adresses of the harddisk (170 range)
     - disable the IRQ (if any).

any IDE drive (one supported in the shareware version
up to two IDE drives for the commercial version).
The setup of the PC will contain the drive types for the MFM drives,
no info on the IDE drive(s)
The driver reads the params form your IDE drive and sets it up.
It does this by reading the Master Boot Record on the IDE.
You can LOADHIGH the driver, so you won't waste any memory <640K
