They're all synonymous, so I'd say that they're different names for a double-sided, high density 5.25" floppy. The difference between 135 and 96 is probably sector sizes. In any case, I wouldn't worry over them at all. > 2. Why they are commented out? Obsolescence, I'd think. > 3. Are these entries mandatory for all floppy disk devices? (Should I > make such lines when I add new mode for floppy disk?) When's the last time you saw new modes for 5.25" floppies? I'm not being sarcastic; I'm just pointing out that they're all obsolete. > > Thanks. > > -----------------------------------------------+--------------------------+ > KATO Takenori <kato@ganko.eps.nagoya-u.ac.jp> | FreeBSD | > Dept.
