 <p>
 The Gentoo Linux 32bit chroot guide will help you setting up a true 32bit chroot for your Gentoo/AMD64 system. 
 </p>
+
 <p>
 As you know 64bit systems don't run 32bit applications natively yet (at least not with portage) so you need to use emulation libraries to make them working or create a true 32bit system inside a chroot to install and run native 32bit applications. For the most common uses you do not need do build a 32bit chroot system. However, if you want to run applications that don't have a binary available to run with 32bit libraries, you should use a 32bit chroot. This guide will teach you how to set up a 32bit chroot and how to install and run applications inside the chroot.

 <title>Installation of your 32bit chroot</title>

 <p>
 To install a 32bit chroot you need to follow many footsteps that you use to install Gentoo Linux on a x86 computer. For now you need the latest stage3 available on our <uri link="http://www.gentoo.org/main/en/mirrors.xml">mirrors</uri>.
 </p>
+
 <pre caption="downloading stage3 from a gentoo mirror">
 $ cd /home/user/downloads
 $ wget -c ftp://distfiles.gentoo.org/releases/x86/2006.1/stages/stage3-i686-2006.1.tar.bz2
 </pre>
+
 <note>Note that we download a stage for x86, <c>not</c> for AMD64.</note>
+
 <p>
 After downloading the stage3 you need to create a new directory to build your new chroot.
 </p>
+
 <pre caption="creating directory for 32bit chroot">
 $ su root <i>insert your root password</i>
 # cd /mnt
 # mkdir gentoo32
 </pre>

 <p>
 Then move the stage you have already downloaded, unpack it and set it up it like this example.

 If everything went well until here now you will be able to set up your new 32bit chroot and finish the installation of this chroot.

 Now you have a true 32bit chroot installed in your 64bits system which is almost ready for use. Next, you need to create a link from your portage available in your 64bit system to your chroot. This way, you only need to update it in one installation instead of duplicating a lot of data.

 <note>Everytime you update your portage by doing a emerge sync, you update your 32bit chroot's portage as well.</note>

 With this chroot you can install many packages available only for x86 arch. Some packages like <c>OpenOffice</c> can be installed by using the binary available for Gentoo/AMD64. Some of the codecs available for <c>MPlayer</c> need this 32bit chroot so you can install <c>win32codecs</c> with this chroot.
