I am a bit disappointed about the answers for floppy problems on the A4000. In my case I wanted to create extra room in my A4000D and I simply removed the floppy and moved the jumper close to the IDE port to set DF0 to external. Now I can use any external drive and it will be recognized as DF0 because the A4000 doesn´t search for an internal floppy anymore. :-o It´s so easy !!
