It would appear that your disk controller is not supported by the 
version of FreeBSD you are trying to run.  Have you checked it against 
the hardware compatibility list?

You can find the controller by looking through /var/run/dmesg.boot - 
with ad0 reconnected of course :-)

You could try a -STABLE or -CURRENT CD to see if support has appeared 
more recently than your release.

I have previously reported an inability to get my amd Freebsd

Device nodes are created automatically when devices are recognised.  If the device isn't recognised there is no point trying to manually create device nodes - it won't help even if you created them correctly.


AFAIK, the only things worth creating in /dev these days are symlimks, which can be done automatically using a devfs.conf rule like
link    acd0    cdrom

The days of MAKEDEV are over as its manpage testifies :-)
