I can now boot nitros9 over DW4! However when I try to access a real floppy on my Tandy FD-502 with /d0 it returns error #240 (no such unit number) In OS9 Lvl II the floppy driver was called CC3Disk (I think) which I can't find under Nitros9. What driver and descriptors do I need to access my physically connected FD-502 floppy drives? Walter
