Oh, I remember I had similar trouble on the FireBee (which emulates 
Falcon hardware). When probing the floppy drives, EmuTOS actually waits 
for an IRQ, whatever the cause. The IDE and floppy share the same IRQ on 
Falcon. I had trouble on the FireBee because a few seconds after reset, 
the CompactFlash card (actually an IDE device) issued an IRQ for an 
unknown cause (probably something like "I'm ready to operate"). That 
interfered with EmuTOS floppy detection routine.

Does Hatari emulates such IDE IRQs, or some other interrupts which could 
interfere with the floppy ? That could explain why I have trouble with 
A: and not B: (which is detected a bit later)...
