Enable this driver if you have an IEEE 1394 controller based on the
OHCI-1394 specification. The current driver is only tested with OHCI
chipsets made by Texas Instruments and NEC. Most third-party vendors
use one of these chipsets. It should work with any OHCI-1394
compliant card, however.

To compile this driver as a module, say M here: the module will be
called ohci1394.

NOTE:
ohci1394 is superseded by the newer firewire-ohci driver. See
http://ieee1394.wiki.kernel.org/index.php/Juju_Migration for
further information on how to switch to the new FireWire drivers.

If you want to install firewire-ohci and ohci1394 together, you
should configure them only as modules and blacklist the driver(s)
which you don't want to have auto-loaded. Add either

blacklist ohci1394
blacklist video1394
blacklist dv1394
or
blacklist firewire-ohci

to /etc/modprobe.conf or /etc/modprobe.d/* and update modprobe.conf
depending on your distribution.
