Unfortunately the list management software ate your photo, but never
mind.  Your verbal description is sufficient.

There may be a good reason for your quad card not being recognised, or
it might just be a bug.

If you run:

   % pciconf -lv

You should be able to pick out your unrecognised device.  If you ask
again on freebsd-net at and include relevant sections from
the pciconf output, you should get to the attention of some of the guys
that write network drivers.

Verb Sap.  Calling FreeBSD a 'distro' is definitely non-U.  We generally
consider penguins a bit fishy round here...

If you want to locate the kernel modules for various hardware, look in
/boot/kernel.  NIC modules will generally have a name beginning 'if_'.

If you want to see what modules have been loaded into the kernel, then

    % kldstat

There's also 'kldload' and 'kldunload' but they aren't going to help you
for this problem.  PCI devices are discovered when the kernel probes the
bus at boot time: if the kernel hasn't already assigned a driver for the
device, then there isn't one available.

Keeps asking good questions and you'll get useful answers.
