      NAME
           fl - floppy disc device driver

      DESCRIPTION
           /dev/fl refers to the floppy disc drive in the Bull-SPS9
           cabinet. A file on the floppy disc is referred to by the
           device name, plus the / character, plus its own name.
           /dev/fl/dog refers to file dog on the floppy disc.

           The floppy disc file name consists of 1 to 15 characters
           from the set [A to Z, a to z, 0 to 9, and "." ]. When
           specifying a pathname, upper- and lowercase characters are
           considered equivalent. The floppy disc directory stores
           names in uppercase only.

           The floppy disc must be doubled-sided, with double-density
           formatting following the IBM 3740 soft-sectored standard. A
           floppy disc is normally formatted by ROS utilities as
           double-sided, double-density with 512 bytes of data per
           block.

           The directory and file structure maintained on a floppy disc
           is compatible with the University of California, San Diego
           (UCSD) Pascal system format. This structure allows up to 77
           files per volume, with a single directory for the entire
           volume.

           ROS utilities are available to format a new floppy disc
           (zero(1)), to list the directory (dir(1)), and to duplicate
           the contents of the floppy (copyfloppy(1)). To compact the
           space allocation of a floppy disc, use copyfloppy(1).
