Editing Loadable kernel module (section)

=== FreeBSD ===
Kernel modules for [[FreeBSD]] are stored within <code>/boot/kernel/</code> for modules distributed with the [[operating system]], or usually <code>/boot/modules/</code> for modules installed from [[FreeBSD ports]] or [[FreeBSD ports#Packages|FreeBSD packages]], or for proprietary or otherwise binary-only modules.  FreeBSD kernel modules usually have the extension <code>.ko</code>. Once the machine has booted, they may be loaded with the <code>kldload</code> command, unloaded with <code>kldunload</code>, and listed with <code>kldstat</code>. Modules can also be loaded from the loader before the kernel starts, either automatically (through <code>/boot/loader.conf</code>) or by hand.
