A kernel module (or loadable kernel mode) is an object file that contains code that can extend the kernel functionality at runtime (it is loaded as needed); When a kernel module is no longer needed, it can be unloaded. Most of the device drivers are used in the form of kernel modules.

make dep clean modules modules_install zImage Having done that, the module dependencies need to be mapped out. This is done with the following command: depmod −a The new kernel now needs to be inserted in the boot chain. I am assuming the reader is using LILO for this purpose, since this is the only loader I have any experience with.
