SEE ALSO
     firewire(4), fwe(4), sbp(4), fwcontrol(8),	kldload(8)

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 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.
