  <title>Installing Without Media</title>
  <para>This section discusses how to install &DISTRO; to your system
    without making any additional physical media.  Instead, you can use
    your existing <application>GRUB</application> boot loader to start
    the installation program.</para>
  <important>
    <title>Linux Required</title>
    <para>This procedure assumes you are already using &DISTRO; or
      another relatively modern Linux distribution, and the
      <application>GRUB</application> boot loader.  It also assumes you
      are a somewhat experienced Linux user.</para>
  </important>
  <section id="sn-medialess-getting-files">
    <title>Retrieving Boot Files</title>
    <para>To perform an installation without media or a PXE server, your
      system must have two files stored locally, a kernel and an initial
      RAM disk.</para>
    <procedure>
      <step>
	<para>Download a Live image or DVD distribution, or to locate an
	  installation mirror, visit <ulink
	    url="http://mirrors.fedoraproject.org/publiclist/Fedora/8/"/>.</para>

      <step>
	<para>Locate the <filename
	    class="directory">isolinux/</filename> folder using one of
	  the following methods:</para>
	<itemizedlist>
	  <listitem>
	    <para>If you chose to download an image, open it with the
	      appropriate desktop tool.  If you are using &DISTRO;,
	      double-click the file to open it with the
	      <application>Archive Manager</application>.  Open the
	      <filename class="directory">isolinux/</filename>
	      folder.</para>
	  </listitem>
	  <listitem>
	    <para>If you chose not to download a whole image because you
	      wish to install via the network, locate the desired
	      release. In general, once you find a suitable mirror,
	      browse to the
	      <filename>releases/&DISTROVER;/&DISTRO;/<replaceable>arch</replaceable>/os/isolinux/</filename> 
	      folder.</para>
	  </listitem>
	</itemizedlist>
	<note>
	  <title>Installation Types Available</title>
	  <para>If you download an image, in the next step you may
	    choose a hard disk-based installation or a network
	    installation.  If you only download selected files from a
	    mirror, in the next step you may only perform a network
	    installation.</para>

      </step>
      <step>
	<para>Copy the <filename>vmlinuz</filename> and
	  <filename>initrd.img</filename> files from the chosen source
	  to the <filename class="directory">/boot/</filename>
	  directory, renaming them to
	  <filename>vmlinuz-install</filename> and
	  <filename>initrd.img-install</filename>You must have
	  <systemitem class="username">root</systemitem> privileges to
	  write files into the <filename

  <section id="sn-medialess-editing-grub-conf">
    <title>Editing the <application>GRUB</application>
      Configuration</title>
    <para>The <application>GRUB</application> boot loader uses the
      configuration file <filename>/boot/grub/grub.conf</filename>. To
      configure <application>GRUB</application> to boot from the new
      files, add a boot stanza that refers to them.</para>
    <para>A minimal boot stanza looks like the following listing:</para>
    <screen><![CDATA[title Installation
        root (hd0,0)
        kernel /vmlinuz-install
        initrd /initrd.img-install]]></screen>
    <para>You may wish to add options to the end of the
      <option>kernel</option> line of the boot stanza.  These options
      set preliminary options in <application>Anaconda</application>
      which the user normally sets interactively.  For a list of
      available installer boot options, refer to <xref
	linkend="ap-admin-options"/>.</para>
    <para>The following options are generally useful for medialess
      installations:</para>
    <itemizedlist>
      <listitem>
	<para><option>ip=</option></para>
      </listitem>

      </listitem>
      <listitem>
	<para><option>ksdevice=</option> (if installation requires an
	  interface other than eth0)</para>
      </listitem>
      <listitem>
	<para><option>vnc</option> and <option>vncpassword=</option> for
	  a remote installation</para>
