PCCARDC(8)              FreeBSD System Manager's Manual             PCCARDC(8)

     pccardc -- PC-CARD (PCMCIA) management and monitoring tool

     pccardc subcommand [arg ...]

     The pccardc utility controls PC-CARD slots and configures and displays
     information about PCMCIA cards.  It understands the following subcom-

     beep         Set beep type
     dumpcis      Print card CIS(s)
     dumpcisfile  Print card CIS(s) from files
     enabler      Device driver enabler
     help         Print command summary
     pccardmem    Allocate memory for pccard driver
     power        Power on/off slots and leaves them disabled
     rdattr       Read attribute memory
     rdmap        Read pcic mappings
     rdreg        Read pcic register
     wrattr       Write byte to attribute memory
     wrreg        Write pcic register

     1.   beep beep_mode

          Specifies the sound made upon card insertion or removal.  This sub-
          command corresponds to pccard_beep in rc.conf(5).  Allowed values
          for beep_mode are:

          0       silent mode
          1       simple beep mode
          2       melody mode

     2.   dumpcis [slot]

          Displays CIS (Card Information Structure) tuple in EEPROM of a PC-
          CARD card.  Slot specifies which slot to read.  When no option is
          supplied, it displays the CIS of all of the available cards.

     3.   dumpcisfile file ...

          Displays CIS(s) in the same format as dumpcis, but does so using one
          or more files as the input CIS data instead of physical PC-CARD

     4.   enabler slot driver [-m card addr size] [-a iobase] [-i irq]

          This is a "point enabler" which can be used to set parameters manu-
          ally to enable a card when pccardd(8) cannot allocate drivers to a
          PC-CARD card properly.  Specify a PC-CARD slot in slot and a device
          name (such as "ed0" or "sio2") in driver, along with some or all of
          the following options:

          -m card addr size
                  maps the shared-memory window of the card to host address.
                  card is the starting address of shared-memory (hex) in the
                  card's address space, addr is the address (hex) to map the
                  memory to in the computer's address space, and size is the
                  size of memory window (kb).

          -a iobase
                  iobase specifies the port a number to be mapped to the I/O
                  window (hex)

          -i irq  irq specifies the IRQ (decimal from 1 to 15) the card will
                  use for interrupts.

          For example,

                  enabler 0 ed0 -m 2000 d4000 16 -a 300 -i 3

          assigns the card in slot zero to the first NE2000 ethernet card
          driver at port 0x300 and IRQ 3, mapping the 16KB memory region at
          0x2000 in the card to 0xd4000.

          This allows use of some unrecognized cards with broken CIS tuples,
          and is also useful for testing a card that has not yet reported.
          However, beware that it frequently cannot recognize new cards prop-

     5.   help

          Prints help for pccardc.

     6.   pccardmem addr

          Specifies the host address using PC-CARD controller(PCIC) will use
          to map cards to.  Because the PCIC needs a contiguous 16KB memory,
          and most machines have other ROMs or devices at other places in the
          ISA I/O memory address range, generally you can only use the follow-
          ing four addresses:

          0xd0000  0xd0000-0xd3fff (default)
          0xd4000  0xd4000-0xd7fff
          0xd8000  0xd8000-0xdbfff
          0xdc000  0xdc000-0xdffff

          You can use "DEFAULT" instead of 0xd0000.  This subcommand corre-
          sponds to pccard_mem in rc.conf(5).

     7.   power slot power_mode

          Changes the state of the power supply of the card in the specified

          0       Turn off a power supply.  If a card becomes unstable when it
                  is removed at activate state, this can force it into inac-
                  tive state first and remove it safely.  The slot will remain
                  disabled until you eject the card with the system running or
                  reenable the card with another pccardc power power command.
                  The slot will even remain disabled when you suspend and
                  resume the computer.

          1       Turn on a power supply and set it into active state (the
                  system treats the card as if it was just inserted).

     8.   rdattr slot offs length

          Prints a hex dump length bytes long of the EEPROM of the card in
          slot slot starting at offs.  All parameters are in hex.

     9.   rdmap [slot]

          Displays where the four memory windows and two I/O windows of a PC-
          CARD slot are mapped to on the host.  If slot is not supplied, it
          displays the information for all of slots in the system.

     10.  rdreg [slot]

          Displays the 64 registers of the card in slot (all slots by

     11.  wrattr slot offs value

          Writes a single byte to the card's EEPROM at an offset address from
          the top specified in offs (hex), with a value specified in value
          (hex).  This is preserved after the card is removed.

     12.  wrreg slot reg value

          Writes a register of a PC-CARD.  Specify a PC-CARD slot number in
          slot, a register number in reg (hex) and a value in value (hex).

     /etc/rc.conf  configuration file

     rc.conf(5), pccardd(8)

     The original version was written by Andrew McRae <>.
     Tatsumi Hosokawa <> fixed bugs and added some
     features.  This man page was written by Toshihiko ARAI

     Be careful when using enabler and wrattr.  Misuse can make the system
     unstable or damage the card.
