I used to use the idefix cd32 emulation and it worked really well. Can't use it now as I have a Mediator.

Anyway, are you running the emulation from a floppy or your hard drive?
I put it on my hard drive bit used to fire it up manually by running a little script as I didn`t want it altering my startup-sequence. Where ever you are running it from, you need to configure it for your system, don't you?
