.Sh NAME
|
||||
.Nm wfd
|
||||
.Nd ATAPI floppy driver (LS-120 floppy driver)
|
||||
.Sh SYNOPSIS
|
||||
.Cd options ATAPI
|
||||
.Cd options ATAPI_STATIC
|
||||
.Cd device wfd
|
||||
.Pp
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
driver provides support for
|
||||
.Em ATAPI
|
||||
floppy disks, typically LS-120 style 120mb/1.4mb floppy drives.
|
||||
In general the interfaces are similar to those described by
|
||||
.Xr wd 4 .
|
||||
.Pp
|
||||
As the IDE controllers are probed during boot, the
|
||||
.Em IDE
|
||||
buses are scanned for devices.
|
||||
Any devices found which answered as
|
||||
.Sq Em Floppy
|
||||
and
|
||||
.Sq Em removable
|
||||
type device will be attached to the
|
||||
.Nm
|
||||
driver.
|
||||
The first device found will be attached as
|
||||
.Em wfd0
|
||||
and the next,
|
||||
.Em wfd1 ,
|
||||
and so on.
|
||||
.Pp
|
||||
When used with a LS-120 drive, this driver will read/write the following
|
||||
types of floppy disk:
|
||||
.Bl -tag -width 1.25MB -compact
|
||||
.It 120mb
|
||||
.It 1.44mb
|
||||
.It 1.25mb (PC-9801 series format)
|
||||
.It 1.2mb
|
||||
.It 720kb
|
||||
.El
|
||||
.Sh PARTITIONING
|
||||
The
|
||||
.Nm
|
||||
driver allows the disk to have two levels of partitioning.
|
||||
One layer, called the
|
||||
.Dq slice layer ,
|
||||
is used to separate the
|
||||
.Tn FreeBSD
|
||||
areas of the disk from areas used by other operating systems.
|
||||
The second layer is the native
|
||||
.Bx 4.4
|
||||
partitioning scheme,
|
||||
.Xr disklabel 5 ,
|
||||
which is used to subdivide the
|
||||
.Tn FreeBSD
|
||||
slices into areas for individual filesystems.
|
||||
For more information, see
|
||||
.Xr fdisk 8
|
||||
and
|
||||
.Xr disklabel 8 ,
|
||||
respectively.
|
||||
.Pp
|
||||
If an uninitialized disk is opened, the slice table will be
|
||||
initialized with a fictitious
|
||||
.Tn FreeBSD
|
||||
slice spanning the entire disk. Similarly, if an uninitialized
|
||||
(or
|
||||
.No non- Ns Tn FreeBSD )
|
||||
slice is opened, its disklabel will be initialized with parameters
|
||||
returned by the drive and a single
|
||||
.Sq Li c
|
||||
partition encompassing the entire slice.
|
||||
.Sh EXAMPLES
|
||||
Making LS-120/ZIP disks can be a bit more complicated than usual depending
|
||||
upon whether or not you chose to use the slice code or not.
|
||||
LS-120 floppies are typically considered floppy devices and do not carry
|
||||
a slice table. On the other hand, Zip disks, which use the same driver,
|
||||
are considered hard disks by the vendor, so for compatibility, you should
|
||||
use a slice table.
|
||||
.Pp
|
||||
The driver will handle either type of disk with or without a slice
|
||||
table, but for compatibility, you should generally create disks
|
||||
that follow the vendor's behavior.
|
||||
.Pp
|
||||
To create a UFS LS-120 disk (no slice table),
|
||||
First, make sure there is no slice table on the disk):
|
||||
.Dl # dd if=/dev/zero of=/dev/wfd0 count=16
|
||||
|
||||
Next, disklabel the disk:
|
||||
.Dl # disklabel -rw wfd0 fd120m
|
||||
|
||||
Then newfs as usual:
|
||||
.Dl # newfs /dev/rwfd0a
|
||||
.Fi
|
||||
|
||||
To create a standard 1.44mb floppy in a LS-120 drive, do the same
|
||||
procedure, but use
|
||||
.Ar fd1440
|
||||
as the disk layout when using the
|
||||
.Nm disklabel
|
||||
command.
|
||||
|
||||
.Sh KERNEL CONFIGURATION
|
||||
Only one
|
||||
.Nm
|
||||
device is necessary in the config file; data structures are dynamically
|
||||
allocated as disks are found on the
|
||||
.Tn IDE
|
||||
buses.
|
||||
.Sh NOTES
|
||||
This driver is attached to the
|
||||
.Xr wdc 4
|
||||
IDE/ATAPI disk controller driver. It will not work unless
|
||||
IDE controllers have been configured and enabled in the kernel.
|
||||
.Sh BUGS
|
||||
Floppy formatting is not yet supported.
|
||||
.Pp
|
||||
This driver is still a beta version.

||||
