How can I read/write MS-DOS floppy disks?
If you have a floppy disk drive on your ULTRIX or OSF/1 system, get
"mtools", a set of MS-DOS utilities for UNIX. The package can be
copied from ftp://prep.ai.mit.edu/pub/gnu/mtools-2.0.7 It works on
both DECstations and Alphas.
When you build mtools, you need to find out which device your floppy
is (/dev/rrz2c is common). Then you can clone the SPARC definitions,
or #define SPARC and make /dev/rfd0c a symlink to the one you need.
