-.Dt MODLOAD 8
-.Os
-.Sh NAME
-.Nm modload
-.Nd load a kernel module
-.Sh SYNOPSIS
-.Nm modload
-.Op Fl dnSsv
-.Op Fl A Ar kernel
-.Op Fl e Ar entry
-.Op Fl o Ar output_file
-.Op Fl p Ar postinstall
-.Ar input_file
-.Sh DESCRIPTION
-The
-.Nm
-utility loads a loadable kernel module into a running system.
-The input file is an object file (.o file).
-.Pp
-The options to
-.Nm
-are as follows:
-.Bl -tag -width Ds
-.It Fl A Ar kernel
-Specify the file that is passed to the linker
-to resolve module references to external symbols.
-The symbol file must be for the currently running
-kernel or the module is likely to crash the system.
-.It Fl d
-Debug.
-Used to debug
-.Nm
-itself.
-.It Fl e Ar entry
-Specify the module entry point.
-This is passed by
-.Nm
-to
-.Xr ld 1
-when the module is linked.
-The default module entry point name is `xxxinit'.
-If `xxxinit' cannot be found, an attempt to use `<module_name>_lkmentry'
-will be made, where <module_name> is the filename being loaded without
-the `.o'.
-.It Fl n
-Do everything, except calling the module entry point (and any
-post-install program).
-.It Fl o Ar output_file
-Specify the name of the output file that is produced by
-the linker.
-.It Fl p Ar postinstall
-Specify the name of a shell script or program that will
-be executed if the module is successfully loaded.
-It is always passed the module id (in decimal) and module
-type (in hexadecimal) as the first two arguments.
-For loadable drivers, the third argument is
-the block or character major device number.
-For a loadable system call, the third argument is the system
-call number.
-.It Fl S
-Do not remove the temporary object file.
-By default, the
-.Xr ld 1
-output is removed after being loaded into the kernel.
-.It Fl s
-Do not load symbols from the kernel module.
-.It Fl v
-Print comments about the loading process.
-.El
-.Sh FILES
-.Bl -tag -width "/usr/include/sys/lkm.hXXX" -compact
-.It Pa /dev/ksyms
-Default file passed to the linker to resolve external
-references in the module.
-.It Pa /usr/include/sys/lkm.h
-File containing definitions of module types.
-.El
-.Sh EXIT STATUS
-The
-.Nm
-utility exits with a status of 0 on success
-and with a nonzero status if an error occurs.
-.Sh SEE ALSO
-.Xr ld 1 ,
-.Xr lkm 4 ,
-.Xr securelevel 7 ,
-.Xr modstat 8 ,
-.Xr modunload 8
-.Sh HISTORY
-The
-.Nm
-command was designed to be similar in functionality
-to the corresponding command in
-.Tn "SunOS 4.1.3" .
-.Sh AUTHORS
-.An Terrence R. Lambert Aq Mt terry@cs.weber.edu
-.Sh BUGS
-.Bl -bullet
-.It
-The loadable device driver framework can
-only reserve either a character or block device entry, not both.
-.It
-Loading the symbol table is expensive in terms of space:
-it presently duplicates all the kernel symbols for each lkm loaded
-with
-.Fl s .
-.El

-.Nd unload a kernel module
-.Sh SYNOPSIS
-.Nm modunload
-.Op Fl i Ar id
-.Op Fl n Ar name
-.Op Fl p Ar postunload
-.Sh DESCRIPTION
-The
-.Nm
-utility unloads a loadable kernel module from a running system.
-The
-.Ar id
-or
-.Ar name
-is the ID or name of the module as shown by
-.Xr modstat 8 .
-.Pp
-One of the following options must be specified:
-.Bl -tag -width indent
-.It Fl i Ar id
-Unload the module with the ID
-.Ar id .
-.It Fl n Ar name
-Unload the module with the name
-.Ar name .
-.It Fl p Ar postunload
-Specify the name of a shell script or program that will be executed if the
-module is successfully unloaded.
-This program is passed no arguments.
-.El
-.Sh EXIT STATUS
-The
-.Nm
-utility exits 0 on success or with a non-zero status if an error occurred.
-.Sh SEE ALSO
-.Xr lkm 4 ,
-.Xr securelevel 7 ,
-.Xr modload 8 ,
-.Xr modstat 8
-.Sh HISTORY
-The
