modload —
load a kernel module
  
    | modload | [ -fP] [-bvar=boolean] [-ivar=integer] [-svar=string] module | 
  
    | modload | -p[-bvar=boolean] [-dvar] [-ivar=integer] [-mplist] [-svar=string] | 
The modload utility loads a kernel module specified by
  the module parameter into the running system.
Modules are loaded from the default system module areas unless the
    module parameter contains a path separator character
    (‘/’).
The options to modload are as follows:
  - -bvar=boolean
- Pass the module a boolean property with the name
      var. boolean may be either
      trueorfalse.
- -dvar
- When used in conjunction with -m, delete
      var from the plist
    specified.
- -f
- When a module is loaded, the kernel checks if the module is compatible
      with the running kernel and will refuse to load modules that are
      potentially incompatible. This option disables compatibility checks.
      Note: an incompatible module can cause system
      instability, including data loss or corruption.
    This option is also required for re-enabling a builtin module
        that was disabled using
        modunload(8). 
- -ivar=integer
- Pass the module an integer property with the name
      var and integral value
      integer.
- -mplist
- When used in conjunction with -p, merge new
      options with an existing property list contained in
      plist.
- -P
- This option tells the kernel not to load an associated property list.
- -p
- Output a property list suitable for loading along with a module. When
      using this option, you do not need to specify a module. Use
      -mand-dto read and
      modify an existing property list.
- -svar=string
- Pass the module a string property with the name var
      and string value string.
Themodload utility exits with a status of 0 on success
  and with a nonzero status if an error occurs.
A modload utility appeared in NetBSD
  0.9. The modload command was designed to be
  similar in functionality to the corresponding command in SunOS 4.1.3.
  modload was switched to the module framework for
  NetBSD 5.0.
The original NetBSD implementation was written by
  Terrence R. Lambert
  <terry@cs.weber.edu>.
  The switch to the module framework was by Andrew Doran
  <ad@NetBSD.org>.
