You put this nice big "M" next to your selected option in menuconfig, and voila, a compiled module will be delivered to you, when you compile the kernel. Then you just simply load the module into memory whenever you need to use it, at boot or at the startup of some service or whenever you want to.

Yeah non of that helps really... anybody else want to try and take a stab at it?

I'd like to point out that its

7.e. Kernel Modules

Configuring the Modules

You should list the modules you want automatically loaded in /etc/modules.autoload.d/kernel-2.4 (or kernel-2.6). You can add extra options to the modules too if you want.

To view all available modules, run the following find command. Don't forget to substitute "<kernel version>" with the version of the kernel you just compiled:

Code Listing 21: Viewing all available modules

# find /lib/modules/<kernel version>/ -type f -iname '*.o' -or -iname '*.ko'

For instance, to automatically load the 3c59x.o module, edit the kernel-2.4 or kernel-2.6 file and enter the module name in it.

Code Listing 22: Editing /etc/modules.autoload.d/kernel-2.4

(Example for 2.4 kernels)
# nano -w /etc/modules.autoload.d/kernel-2.4

Code Listing 23: /etc/modules.autoload.d/kernel-2.4 or kernel-2.6

3c59x


This whole bit i'm having trouble with

Well. It is difficult to explain everything in one article and you should read some doc. There is plenty of relevant articles in http://www.gentoo.org/doc/ and not only gentoo, every linux distro uses kernel. For the start I would rcommend to read http://www.gentoo.org/doc/en/kernel-config.xml#doc_chap2

vladimirm,

You will find some useful kernel reading in /usr/src/linux/Documentation.

Optional kernel code (modules) can be selected to be used in two ways.
Configuring as [*] includes the core in the kernel bzImage file, which is copied to /boot when the kernel is installed.
This is the file thats loaded by grub as part of the startup process.
Configuring as [M] makes seperately loadable modules. They are copied to /lib/modules/`uname -r`\ by the make modules_install command.
This way, each kernel has its own modules path.

From the above, if you change a [*], a full kernel rebuild, install and reboot is required. When you change a [M] option, all that required is

Right cheers for all that, i'll read through the documentation and cheers for the help
