+.Sh NAME
+.Nm fwohci
+.Nd OHCI FireWire chipset device driver
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following line in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device firewire"
+.Ed
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+firewire_load="YES"
+.Ed
+.Pp
+To disable physical access (see
+.Sx BUGS
+section for detail), put the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+hw.firewire.phydma_enable=0
+.Ed
+.Sh HARDWARE
+The
+.Nm
+driver provides support for PCI/CardBus FireWire interface cards.
+The driver supports the following IEEE 1394 OHCI chipsets:

+.Sh HISTORY
+The
+.Nm
+device driver first appeared in
+.Fx 5.0 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+device driver was written by
+.An Katsushi Kobayashi
+and
+.An Hidetoshi Shimokawa .
+.Sh 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
+.Xr 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.
