NAME
       pccard -- PC Card bus driver

SYNOPSIS
       device pccard

DEPRECATION NOTICE
       This   driver  is  scheduled  for  removal  prior  to  the  release  of
       FreeBSD 13.0.

DESCRIPTION
       The pccard driver implements the	PC Card	bus.  The pccard  driver  sup-
       ports all PC Card bridges in the	system.

TUNABLES
       The  driver  supports  the  following  tunable parameters, which	may be
       added to	/boot/loader.conf or set via the sysctl(8) command:
       hw.pccard.debug	    Non-zero values cause more verbose information  to
			    be	printed	 when  a 16-bit	PC Card	is inserted or
			    removed.
       hw.pccard.cis_debug  Non-zero value  causes  the	 CIS  parsing  of  the
			    16-bit PC Card to be much more verbose and include
			    a complete CIS dump.

FILES
       /dev/pccard0.cis	 This  exclusive-use  device  will  report all the CIS
			 chains	present	in a PC	Card, if a 16-bit PC  Card  is
			 inserted  in  the  slot.  Only	one user at a time may
			 access	the CIS.  The CIS is presented as the relevant
			 byte stream from the PC Card.	For CIS	tuples in  At-
			 tribute Memory	(the default), only the	even locations
			 are  presented	 (the  ODD locations are undefined per
			 the standard).	 For  CIS  tuples  in  Common  Memory,
			 every byte is presented to the	user.  Decoding	of the
			 CIS  tuples  is done via a userland program.  All tu-
			 ples are presented to the user.
