the best method would probably be to put a

dumpdev="/dev/ad0s1b"

statement into your /etc/rc.conf (see rc.conf(5)) to enable crash dumps.

'man dumpon' says to use the dumpdev variable of 'loader' for panics which happen before the rootfs is mounted -- as in this case.

The 'show' command at the loader prompt doesn't show a dumpdev variable.
I tried 'set dumpdev=disk1s2b:' which was accepted by the loader but
it didn't result in a crashdump.

I wasn't sure about what value to give for the dumpdev variable, and
I wasn't sure about the : after the name of the disk.  I noted that
the rootdev had a : following the name of the disk.

Can you tell if any of this sounds right?  Anything I should be doing
differently?

Thanks!
