Again, ndiswrapper doesn't use /lib/firmware.  Those messages are not
coming from ndiswrapper.  Please forget about ndiswrapper unless/until
you have actually tried using b43 on an F7, F8, or Rawhide kernel.

The b43 driver requires version 4 firmware.  Using an F8 kernel,
the firmware needs to be extracted with b43-fwcutter.

Once you install or upgrade to F8, the easiest method I can offer
you to get this working is to download and install this package:


Then you will need to establish a wired connection to the Internet.
Afterwards you can either reboot (presuming your wired configuration
was configured with system-config-network) or run the following command
(as root):


I'm sorry, but I can't be confident that even the latest FC6 kernels
will support your card.  I also doubt that the rpm above will work
on anything earlier than at least F7.  Your best bet to get your
4318 working is to use a modern Fedora installation.  If your 4318
doesn't work with the stock F8 kernels then you can always fall back
on ndiswrapper, which I presume will still work (although I cannot
support it).
