I never get any output from pnpinfo.  I have several different machines
running FreeBSD 4.2-RELEASE and FreeBSD 4.3-RELEASE.  All systems have PnP
motherboards.  In fact, the kernel can find and use most of the PnP devices
on the systems.  But when I run pnpinfo all it says is

    Checking for Plug-n-Play devices...
    No Plug-n-Play devices were found

I recompiled pnpinfo with -DDEBUG, and it gives this output:

    Checking for Plug-n-Play devices...
    Trying Read_Port at 203...
    Trying Read_Port at 243...
    Trying Read_Port at 283...
    Trying Read_Port at 2c3...
    Trying Read_Port at 303...
    Trying Read_Port at 343...
    Trying Read_Port at 383...
    Trying Read_Port at 3c3...
    No Plug-n-Play devices were found

The only reason I am started down this road is that the system does not
recognize two PnP devices on one system: the parallel port hardware and
the builtin modem.  I was going to add the necessary strings to sio.c
and ppc.c so they would be recognized automatically at boot time.  The
work-around is easy: configure the devices in the config file as non-PnP
devices.  But sometimes it would just generally be useful to be able
to use the pnpinfo command.

I have made at least a half-hearted search through the PRs, the FAQs,
the handbook, and the mailing lists, but to no avail.  Several people
have reported the opposite problem: pnpinfo works, but they can't get
the devices to work.  But I don't seem to see anybody with my particular
problem.

Any idea why I cannot get pnpinfo to work?

A couple different things I have already tried which made no difference:

- Changing the BIOS setting of "PnP Operating System" back and forth
  between YES and NO.

- Compiling the kernel with and without "options PNPBIOS".
  Looking at the code for pnpbios, this one seems like it should
  be irrelevant.

Thanks!
