NAME
fl
- console floppy interface
DESCRIPTION
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.

HISTORY
The
fl
driver appeared in
4.0BSD.
BUGS
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.
