I have solved the problem and have all three IDE drives working. The problem
was that the IDE controller I bought did not support IRQ 15; it would appear
that many of these controllers are designed with DOS in mind, thus when used
with a dos driver the secondary controller is polled and not interrupt
driven. The solution is to make sure that the ide controller supports IRQ 14
for the primary controller, and IRQ 15 if set up as a secondary controller !

In the end I purchased a UMC EIDE VL-bus controller that supports 4 IDE
drives, etc...  This even came with a driver that works with OS/2.x. I now
have a system with three drives that is running a hell of a lot faster thanks
to the supplied UMC driver !

It is about time that hardware manufacturers learnt that there is more to
life than MS-DOS <grin>.
