<p><strong>Debian GNU/Linux 4.0 has been superseded by
<a href="../../lenny/">Debian GNU/Linux 5.0 (<q>lenny</q>)</a>. Some of these
installation images may no longer be available, or may no longer work, and
you are recommended to install <q>lenny</q> instead.
</strong></p>
<h1>Installing Debian GNU/Linux <q>etch-and-a-half</q></h1>
<h2>Overview</h2>
<p>
The <q>etch-and-a-half</q> release is essentially just the most recent
point release for etch, but with a more recent kernel (version 2.6.24).
The main purpose of this release is to allow installation of <q>etch</q>
on systems not supported by the 2.6.18 kernel that is used in regular
<q>etch</q> installs.
</p>
<p>
For further details about scope, purpose and limitations of the
<q>etch-and-a-half</q> release, see the
<a href="../etchnhalf">Release Notes</a>.
</p>
<h2>Installing</h2>
<p>
For new installations of <q>etch-and-a-half</q> the current release of
<em>Debian Installer for <strong>lenny</strong></em> is used, with minor
changes for compatibility with <q>etch</q>.
</p>
<p>
Please read the notes below carefully before installing <q>etch-and-a-half</q>.
</p>
<ul>
<li>Because the current <q>lenny</q> installer is an RC release, it
may have some errata you would not expect in a stable release.
See the <a href="#errata">errata section</a> at the bottom of this
page for details.</li>
<li>The <q>lenny</q> installer includes a number of changes from the
<q>etch</q> installer. See the release announcements for the
<a href="$(HOME)/devel/debian-installer/News/2008/20080317">beta1</a>,
<a href="$(HOME)/devel/debian-installer/News/2008/20080609">beta2</a>,
<a href="$(HOME)/devel/debian-installer/News/2008/20081112">RC1</a> and
<a href="$(HOME)/devel/debian-installer/News/2009/20090131">RC2</a>
releases of the installer for an overview of changes.</li>
<li>This includes changes that affect preseeding (automated
installations). See the appendix on preseeding in the Installation
Guide for <q>lenny</q> (linked below) for correct preseeding options.</li>
</ul>
<p>
The following installation options are available to install Debian GNU/Linux
<q>etch-and-a-half</q>.

<p>
<strong>Additional notes</strong>
</p>
<ul>
<li>
The current <q>etch-and-a-half</q> installation images based on
Debian Installer Lenny RC1 use a newer kernel (2.6.26) than the
version that was included in the <q>etch-and-a-half</q> release
and is installed for the target system (2.6.24). In some cases this
can mean that hardware which is supported during the installation
does not work after the reboot into the installed system because
support for it was added after the 2.6.24 version.
</li><li>
If any of the hardware in your system requires firmware to be loaded
with the device driver, the installer may ask if it should load the
firmware from a removable medium, such as a floppy disk or USB stick.
General information about loading firmware during an installation can
be found in the Installation Guide (see Documentation below).
</li><li>
For the installation images, verification files (<tt>SHA256SUMS</tt>,
<tt>SHA512SUMS</tt> and other) are available from the same directory as the
images.
</li><li>
There are two reasons the netinst image is only available for selected
architectures. First, a lot of architectures don't really have new
hardware that is not supported by the 2.6.18 kernel. Second, some
architectures are most commonly installed using netboot, making the CD
image unnecessary.
</li>
</ul>
<h2>Documentation</h2>
<p>
<strong>If you read only one document</strong> before installing, read our
<a href="../../lenny/i386/apa">Installation Howto</a>, a quick
walkthrough of the installation process. Other useful documentation includes:

<ul>
<li>
The <q>etch-and-a-half</q> 4.0r5 netinst images for both i386 and amd64 had some
minor problems with the isolinux boot menu. This was fixed in the 4.0r5a images.
