.Nm lmmon

information
.Sh SYNOPSIS
.Nm lmmon
.Op Fl hipsv
.Op Fl r Ar delay
.Sh DESCRIPTION
.Nm
lmmon is a console application to display information
associated with information received from a motherboard
power management controller.  By default it cycles once
every second using a curses-based display.
.Pp
The following options are available:
.Bl -tag -width indent
.It Fl h
Display help.
.It Fl i
Use /dev/io interface instead of /dev/smb0.  Required for
FreeBSD 3.x (prior to 01 November 1999) and some
motherboards without actual LM78/79 chipsets.
.It Fl m
Simple output format, suitable for further processing.  
Forces -p and -s.
.It Fl p
Plain display (no curses).
.It Fl r Ar delay
Redisplay every
.Ar delay
seconds (default 1).
.It Fl s
Single-shot mode (run once).
.It Fl v
Display version information.
.El
.Pp
The following kernel configuration options are
required to use the /dev/smb0 interface:
.Bd -literal -offset indent
\&controller      smbus0
\&controller      iicbus0
\&controller      iicbb0  
\&controller      intpm0                
\&device          smb0    at smbus?
.Sh BUGS
Currently, the
.Xr intpm 4
controller is only available in FreeBSD 4.0 and
3.3-STABLE after 01 November 1999; however, the
/dev/io interface may work on older versions and
a wider variety of motherboards.
