FL(4) BSD/vax Kernel Interfaces Manual FL(4)NAMEfl — console floppy interface
This is a simple interface to the DEC RX01 floppy disk unit, which is
part of the console LSI-11 subsystem for VAX-11/780s. Access is given to
the entire floppy consisting of 77 tracks of 26 sectors of 128 bytes.
All I/O is raw; the seek addresses in raw transfers should be a multiple
of 128 bytes and a multiple of 128 bytes should be transferred, as in
other “raw” disk interfaces.
The fl driver appeared in 4.0BSD.
Multiple console floppies are not supported.
If a write is given with a count not a multiple of 128 bytes then the
trailing portion of the last sector will be zeroed.
