+!!! Updating the [Kernel] SourceCode without reconfiguring from scratch

+Download and unpack the latest [Kernel] TarBall (ie from [http://kernel.org/]). Copy the <tt>.config</tt> file from the previous [Kernel]'s directory to the fresh one. From the new directory, run <tt>make oldconfig</tt> to pick up the old configuration, then <tt>make menuconfig</tt> to change any options for the new [Kernel].

+apt-get kernel-source-''version''

!!! Compiler Version
The [Kernel] can be sensitive to the version of [GCC] in use. F.ex. 2.4 and early 2.6 kernels did not work with [GCC] 3.x. They contained the following snippet in <tt>README</tt>:

OTOH kernels since about 2.6.15 require [GCC] 3.x. Read the file to find the versions of compilers and other tools you need. Make sure to check the <tt>README</tt> and <tt>Documentation/Changes</tt> files to find out which version you need. Of course you always read the compile instructions for software you download, right? :)
To compile a kernel with a specific compiler, you can say eg. <tt>make CC=gcc-2.95 bzImage</tt> to make the <tt>bzImage</tt> target using the <tt>gcc-2.95</tt> compiler.
