f you don't have a serial console, there's another way to do it, one I
stepped into accidentally, and it took me a long while to recover from.
There's a different line you could have put into the /boot/loader.conf
file, one that says "boot_mute=YES".  That's going to silence all of the
probing messages completely.  The way it bit me (and you probably ought to
be aware of it) is that it works exactly the same, if you had entered
"boot_mute=NO" or even "boot_mute=Cincinnati", in all cases, the boot
messages are a goner, it's only reading that the word "boot_mute" is being
set, and what it's being set to really doesn't get into the act.

Took me a really long time to learn that one.  I won't soon forget it.
