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 supports 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
                         Attribute 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 tuples are presented to the user.
