The original PC started out with single-sided, 160K drives, with 8 sectors/track, later on DOS started using 9 sectors/track. Nowadays DOS still uses 9 sectors/track, while other OS's use more, 10 or 11, the amiga packs 880K on a 3.5" disk. The hardware and diskettes is the same, and since Minix is not bound by MS-DOS, is it possible to put more than 720K on a 3.5" disk ? I am not sure about 5.25" disks since people with original IBM-PC's might also run Minix, but 3.5" drives are considerably newer and in my experience more reliable. > > Vincent > > >Vincent Archer | Email:archer%segin4.segin.fr@prime.com >"People that are good at finding excuses are never good at anything else" Newsgroups: comp.os.minix Subject: Re: Needing TOS to format (was Needing DOS to format) References: <21669@nigel.udel.EDU> Organization: Eindhoven University of Technology, The Netherlands In article <21669@nigel.udel.EDU> archer%segin4.segin.fr@prime.com (Vincent Archer) writes: >To use the format (as in format dd0), one should have the 1.5 kernel, fs, the >format command, and define /dev/fmtfd0, /dev/ftmfd1, /dev/fmtdd0, /dev/fmtdd1 >with major number 3 and minor numbers 64, 65, 72 and 73 (64+minors of fd0, fd1, >dd0 and dd1).
