Oh, so there is a bug in EmuTOS floppy routines. Strangely, it works
fine with ARAnyM... It also works fine on Hatari with ST/TT hardware,
with any CPU/speed combination. But it fails on Hatari as soon as Falcon
hardware is selected.
Some info from Didier Méquignon:
In HD bits 0/1 of 0xFFFF860E.W are set.
In DD bits 0/1 of 0xFFFF860E.W are cleared.
Why 2 bits, I don't know.
Also, EmuTOS uses the bit 6 of the hardware DIP switches to detect a
High Density floppy drive. But this information is not used afterwards.
I will have to make some investigation...
