MODLOAD(8) Maintenance Procedures MODLOAD(8)


modload - load a kernel module


modload [-p] [-e exec_file] filename


The modload command loads the loadable module filename into the running

filename is an object file produced by ld -r. If filename is an absolute
pathname then the file specified by that absolute path is loaded. If
filename does not begin with a slash (/), then the path to load filename
is relative to the current directory unless the -p option is specified.

The kernel's modpath variable can be set using the /etc/system file. The
default value of the kernel's modpath variable is set to the path where
the operating system was loaded. Typically this is /kernel /usr/kernel.

For example, the following command looks for ./drv/foo:

example# modload drv/foo

The following command looks for /kernel/drv/foo and then

example# modload -p drv/foo


The following options are supported:

-e exec_file
Specify the name of a shell script or executable image
file that is executed after the module is successfully
loaded. The first argument passed is the module ID (in
decimal). The other argument is module specific. The
module specific information is: the block and character
major numbers for drivers, the system call number for
system calls, or, for other module types, the index into
the appropriate kernel table. See modinfo(8)

Use the kernel's internal modpath variable as the search
path for the module.

Use add_drv(8) to add device drivers, not modload. See for procedures on
adding device drivers.
