Subject: Boot process, kernel.conf, and "di" commands

I'm trying to figure out a bit of how the boot process works. I've
gotten quite a bit of information from the man pages and the handbook,
but I still am missing something.

First, I'm running 3.4-RELEASE.

When I boot I used to get a bunch of lines on the order of:
config> di zp0
config> di ze0
config> di lnc0
config> di le0
config> di ie0
config> di fe0
config> di ex0
config> di ed0
config> di cs0
config> di wt0
config> di mcd0
config> di matcdc0
config> q

This looks a lot like a list of NIC cards, although not all of
the ones supported by FreeBSD. Perhaps those which need pccard
support?

In any case, I rebuilt my kernel and commented out all of the cards I
know I didn't have and I now get:
config> di zp0
No such device: zp0
Invalid command or syntax.  Type `?' for help.
config> di ze0
No such device: ze0
Invalid command or syntax.  Type `?' for help.
and so on.

I found that the file kernel.conf seems to have these commands, but
what are they? Do I need them for pccard NICs? My laptop has a Xircom
card and I have configured it into my kernel (although I have yet to
boot it). Do I need a "di xe0" in my kernel.conf file? Is there a man
page for what ever program is generating the 'config> ' prompts?

Any clues appreciated.
