Well, I think that's an error in the fdc emulation that timeouts too 
soon when no disk is inserted (or an unformatted disk (but you can't do 
this with ST/MSA)). I should wait 1.6 sec for each read access when no 
disk is in drive, but at the moment I just returns immediatly with the 
appropriate error bit in the status register.

MY 520 STF takes 54 sec to boot to desktop when no disk is in drive, so 
maybe emutos checks the floppy in a different way, but it doesn't seem 
too much different from real ST if it takes 34 sec.

I'll take a look later to see how I can slow down the fdc when no disk 
is present ;)  (it doesn't really matter for 1.7)


By the way, don't we miss an option to boot without an already 
configured gemdos HD drive ? I can't see it (only option is to press F12 
and eject on gemdos drive).
