pccardc(8)

NAME

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

SYNOPSIS

     pccardc subcommand [arg ...]

DESCRIPTION

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

     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
	  cards.

     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

	  -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-
	  erly.

     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
	  slot:

	  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]

	  default).

     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).

BUGS

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