DESCRIPTION
Themodload
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:
-b
var=boolean- Pass the module a boolean property with the name
var. boolean may be either
true
orfalse
. -d
var- 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).
-i
var=integer- Pass the module an integer property with the name var and integral value integer.
-m
plist- 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
-m
and-d
to read and modify an existing property list. -s
var=string- Pass the module a string property with the name var and string value string.
DIAGNOSTICS
The modload
utility exits with a status of
0 on success and with a nonzero status if an error occurs.

HISTORY
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.
AUTHORS
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>.
