NAME

     tnt4882 -- National Instruments TNT4882A GPIB controller driver

SYNOPSIS

     device tnt4882

DESCRIPTION

     The tnt4882 driver provides support for driving an IEEE-488 bus, also called IEC-625 (or just "IEC bus"), or HP-IB (Hewlett Packard Instru-
     ment Bus), or GPIB (General Purpose Instrument Bus).  The driver supports National Instruments PCI GPIB cards using the TNT4882 bus interface
     chip.  This chip emulates a NEC uPD7210 controller IC as the main interface between the host computer and the instrument bus.

SEE ALSO

     gpib(3), gpib(4)

HISTORY

     The tnt4882 driver was written by Poul-Henning Kamp, and first appeared in FreeBSD 5.4.

NAME

     fwohci -- OHCI FireWire chipset device driver

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device firewire

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   firewire_load="YES"

     To disable physical access (see BUGS section for detail), put the following line in loader.conf(5):

	   hw.firewire.phydma_enable=0

HISTORY

     The fwohci device driver first appeared in FreeBSD 5.0.

AUTHORS

     The fwohci device driver was written by Katsushi Kobayashi and Hidetoshi Shimokawa.

BUGS

     The driver allows physical access from any nodes on the bus by default.  This means that any devices on the bus can read and modify any mem-
     ory space which can be accessed by an IEEE 1394 OHCI chip.  It is allowed mostly for sbp(4) devices.  This should be changed to allow it only
     for specific devices.  Anyway, FireWire is a bus and not expected to be connected with un-trustable devices because a node can monitor all
     the traffic.
