# Installing a kernel

A kernel is the heart of a Linux system. We could use the kernel image from our normal system, but we might as well compile a new kernel from the most recent kernel sources available.

Building the kernel involves a few steps: configuring it and compiling it. There are a few ways to configure the kernel. If you don't like the way this book does it, read the `README` file and find out what your other options are. Run the following commands to build the kernel:

> `cd /usr/src/linux &&`
> `make mrproper &&`
> `make menuconfig &&`
> `make dep &&`
> `make bzImage &&`
> `make modules &&`
> `make modules_install &&`
> `cp arch/i386/boot/bzImage /boot/lfskernel &&`
> `cp System.map /boot`
