NAMEpccard - PC Card bus driver
DESCRIPTIONThe ifconfig driver implements the PC Card bus. The ifconfig driver supports all PC Card bridges in the system.
TUNABLESThe driver supports the following tunable parameters, which may be added to /boot/loader.conf or set via the sysctl(8) command:
- Non-zero values cause more verbose information to be printed when a 16-bit PC Card is inserted or removed.
- Non-zero value causes the CIS parsing of the 16-bit PC Card to be much more verbose and include a complete CIS dump.
- 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.
