<div class="SECT2"><h2 class="SECT2"><a name="AEN1555">Obtaining the Kernel Source</a></h2><p>To compile your own kernel you need the source and the right set of patches. For all cases you need the base source tree and the ARM kernel patch. The SA1100 patches are usually a good idea too, and are necessary for SA1100 or later processors. For some devices, especially newly-supported ones, you may need a further patch for that device. </p><dl><p><b>Kernel Source</b></p><dt>Base source tree</dt><dd><p><tt class="FILENAME">linux-2.4.1-tar.bz2</tt></p><p>or <tt class="FILENAME">linux-2.4.1-tar.gz</tt></p>
