+.Sh NAME
+.Nm mopd
+.Nd MOP loader daemon
+.Sh SYNOPSIS
+.Nm mopd
+.Op Fl 3 | 4
+.Op Fl adfv
+.Ar interface
+.Sh DESCRIPTION
+.Nm
+services MOP Load requests on the Ethernet connected to
+.Ar interface
+or all interfaces if
+.Fl a
+is given.
+In a load request received by
+.Nm
+a filename can be given.
+This is the normal case for, e.g., terminal servers.
+If a filename isn't given,
+.Nm
+must know what image to load.
+.Pp
+Upon receiving a request,
+.Nm
+checks if the requested file exists in
+.Pa /tftpboot/mop .
+The filename is normally all uppercase and with an extension of
+.Pa .SYS .
+If the filename isn't given, the Ethernet address of the target is used as
+filename (e.g.,
+.Pa 08002b09f4de.SYS ) ,
+and it might be a soft link to another file.
+.Pp
+.Nm
+supports two kinds of files.
+The file is first checked to see if it is in a.out format.
+If not, a few of Digital's formats are checked.
+.Pp
+In normal operation,
+.Nm
+forks a copy of itself and runs in
+the background.
+Anomalies and errors are reported via
+.Xr syslog 3 .
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl 3
+Ignore MOP V3 messages (Ethernet II).
+.It Fl 4
+Ignore MOP V4 messages (Ethernet 802.3).
+.It Fl a
+Listen on all the Ethernets attached to the system.
+If
+.Fl a
+is omitted, an interface must be specified.
+.It Fl d
+Run in debug mode, with all the output to stdout.
+The process will run in the foreground.
+.It Fl f
+Run in the foreground.
+.It Fl v
+Show version of
+.Nm .
