'change fda /dev/zero' gets things straight again. Actually, when I start qemu with -fda /dev/zero, the floppy drive is detected ok. So that would be a very quick fix to the problem. The only remaining problem is that I get a segfault when I try to format the virtual floppy when it points to /dev/zero (I would expect a 'disk is write protected' error). Johannes
