FWOHCI(4)	       FreeBSD Kernel Interfaces Manual		     FWOHCI(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 follow-
     ing line in loader.conf(5):

	   hw.firewire.phydma_enable=0

HARDWARE
     The fwohci	driver provides	support	for PCI/CardBus	FireWire interface
     cards.  The driver	supports the following IEEE 1394 OHCI chipsets:

     o	 Adaptec AHA-894x/AIC-5800
     o	 Apple Pangea
     o	 Apple UniNorth
     o	 Intel 82372FB
     o	 IOGEAR	GUF320
     o	 Lucent	/ Agere	FW322/323

     o	 NEC uPD72870
     o	 NEC uPD72871/2
     o	 NEC uPD72873
     o	 NEC uPD72874
     o	 National Semiconductor	CS4210
     o	 Ricoh R5C551
     o	 Ricoh R5C552
     o	 Sony CX3022
     o	 Sony i.LINK (CXD3222)
     o	 Texas Instruments PCI4410A
     o	 Texas Instruments PCI4450
     o	 Texas Instruments PCI4451
     o	 Texas Instruments TSB12LV22
     o	 Texas Instruments TSB12LV23
     o	 Texas Instruments TSB12LV26
     o	 Texas Instruments TSB43AA22
     o	 Texas Instruments TSB43AB21/A/AI/A-EP
     o	 Texas Instruments TSB43AB22/A
     o	 Texas Instruments TSB43AB23
     o	 Texas Instruments TSB82AA2
     o	 VIA Fire II (VT6306)

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 memory
     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 con-
     nected with un-trustable devices because a	node can monitor all the traf-
     fic.
