Printing current settings
-------------------------

`-T'
`--type'
     Print out the drive name of a floppy device. This is used by the
     `MAKEFLOPPIES' script. The drive name is a letter (describing the
     drive type) followed by the capacity of the format in bytes. The
     letter is E for 3.5 ED drives, H for 3.5 HD drives, D for 3.5 DD
     drives, h for 5.25 HD drives and d for 5.25 DD drives. The drive
     type letter corresponds to the oldest drive type supporting the
     format of this device node (not necessarily the type of the drive
     refered by this node.)  For the generic format nodes (/dev/fd0 et
     al.)  the name of "native format" of the drive is printed, and for
     the default formats, if a generic format has been redefined, its
     name becomes `(null)'.

`-p'
`--print'
     Prints out the configuration of the drive. The names of the various
     fields are the same as the names of the option to set them, see
     below.

`-P'
`--printstate'
     Prints out the cached internal state of the driver. The first line
     lists various attributes about the disk:
    `drive present'
    `disk present'
    `disk writable'
          These are only updated when the drive is accessed.

    `spinup'
          is the time when the motor became switched on for the last
          time.

    `select'
          is the time when the drive became selected for the last time

    `first_read'
          is the time when the first read request after the last spin up
          completed.

    `probed_fmt'
          is the the index of the autodetected format in the
          autodetection sequence for this drive.

    `cylinder'
          is the cylinder where the drive head currently sits.  If this
          number is negative, it has the following meaning:
             * -1 means that the driver doesn't know, but the
               controller does (a seek command must be issued).

             * -2 means that the controller doesn't know either, but is
               sure that it not beyond the 80th track.  The drive needs
               a recalibration.

             * -3 means that the head may be beyond the 80th track.
               The drive needs two successive recalibrations, because
               at each recalibration, the controller only issues 80
               move head commands per recalibration.

    `maxblock'
          is the highest block number that has been read.

    `maxcylinder'
          is a boolean which is set when a sector that is not on
          cylinder 0/head 0 has been read.  These are used for smart
          invalidation of the buffer cache on geometry change.  The
          buffer cache of the drive is only invalidated on geometry
          change when this change actually implies that a block that
          has already been read changes position. This optimization is
          useful for mtools which changes the geometry after reading
          the boot sector.

    `generation'
          is roughly the number of disk changes noticed since boot.
          Disk changes are noticed if the disk is actually changed, or
          if a flush command is issued and for both cases if any I/O
          to/from the disk occurs. (i.e. if you insert several disks,
          but don't do any I/O to them, the generation number stays the
          same.)

    `refs'
          is number of open file descriptors for this drive. It is
          always at least one, because floppycontrol's file descriptor
          is counted too.

    `device'
          is format type (as derived from the minor device number)
          which is currently being used.

    `last_checked'
          is date (in jiffies) when the drive was last checked for a
          disk change, and a disk was actually in the drive.

`--pollstate'
     Polls the drive and then prints out the internal state of the
     driver.(`--Printstate' only prints out the cached information
     without actually polling the drive for a disk change.)

`--printfdcstate'
     Prints out the state of the controller where the target drive is
     attached to.
    `spec1'
    `spec2'
          are the current values of those registers.

    `rate'
          is current data transfer rate

    `rawcmd'
          is true if a raw command has been executed since the last
          reset. If this is the case, a reset will be triggered when a
          drive on the same FDC is next opened.

    `dor'
          is the value of the digital output register. The 4 high bits
          are a bit mask describing which drives are spinning, the 2
          low bits describe the selected drive, bit 2 is used to reset
          the FDC, and bit 3 describes whether this FDC has hold of the
          interrupt and the DMA. If you have two FDCs, bit 3 is only
          set on one of them.

    `version'
          is the version of the FDC. See `linux/include/linux/fdreg.h'
          for a listing of the FDC version numbers.

    `reset'
          is true if a reset needs to be issued to the FDC before
          processing the next request.

    `need_configure'
          is true if this FDC needs configuration by the `FD_CONFIGURE'
          command.

    `has_fifo'
          is set if the FDC understands the `FD_CONFIGURE' command.

    `perp_mode'
          describes the perpendicular mode of this FDC. 0 is
          non-perpendicular mode, 2 is HD perpendicular mode, 3 is ED
          perpendicular mode, and 1 is unknown.

    `address'
          is the address of the first I/O port of the FDC.  Normally,
          this is 0x3f0 for the first FDC and 0x370 for the second.
