<title>Before You Begin</title>
<para>Welcome to the Adélie Linux 1.0 Installation Guide. This guide will describe the process you will use to install Adélie Linux on to a computer.</para>
<para>If you are installing Adélie Linux to your main computer, you may use another device - such as a mobile phone or a friend's laptop, if available - to follow along with this guide.
Additionally, most portions of this guide are available on the installation CD for viewing during installation. Just choose "Help" from any page in the Horizon Installation Wizard.</para>
<section>
<title>Preparing for the installation</title>
<para>Please back up all of your data before beginning installation.
While every effort is made to ensure that the Adélie Linux installation routines are safe and error-free, we cannot guarantee that your data will be preserved once you start the installation.
If you intend on dual-booting your computer with another operating system, such as Mac OS X or Windows, ensure there is adequate disk space available to install Adélie Linux.
You will need up to 1 GB for a standard desktop installation, or at least 300 MB for a server installation.</para>
<para>To install Adélie Linux to a desktop or portable computer, you will need a display capable of at least 800x600 pixel resolution.
Most common desktop displays display in at least this resolution. HiDPI (or "Retina") displays are supported only on the KDE Desktop installation media.
Please note that the server installation media may render incorrectly, or even not at all, when using HiDPI displays.
You may install server packages using the desktop installation media if you need to use a HiDPI display during server installation.</para>
<para>To install Adélie Linux to a server, you will need either a display capable of at least 80x25 text console (720x480), or a supported serial line.
If you are installing via serial line, be sure you know your server's serial line settings.
Most servers default to either 9600 or 57200 baud; Adélie Linux does not reconfigure the serial line, so you will need to know your firmware's default settings.</para>
<para>If you plan on connecting to the Internet directly from your Adélie Linux computer without using a router (not common),
ensure you have your Internet access credentials (typically a username and password) available before starting installation.
Adélie Linux supports connecting to most ADSL and dial-up Internet providers using PPP; and cable, T1, and fibre providers using Ethernet.
If you use a static IP address (not common), make sure you have your IP address, subnet, and default gateway and nameserver settings before starting installation.</para>
<para>If your computer came with recovery media, we recommend that you have it available in the very unlikely event you have an issue with Adélie Linux, or your hardware has an incompatibility.
This way, you will be able to quickly restore your computer to normal operation.</para>

<title>Creating the installation media</title>
<para>You will need either:</para>
<itemizedlist>
<listitem><para>a <hardware>CD drive</hardware> capable of burning a CD, and a blank CD; or</para></listitem>
<listitem><para>a blank <hardware>USB flash drive</hardware>.</para></listitem>
</itemizedlist>
<para>Download the installation media file from your local Adélie Linux mirror. Follow the instructions on the mirror's site to choose the media file appropriate for your computer.
Then, follow the steps below for your current operating environment.</para>

<title>Using Linux or BSD</title>
<para>On Linux or BSD systems, you can use either <command>cdrecord</command> or <command>cdrskin</command> to write the installation image to a CD via the command line. Both commands basically share the same syntax.</para>
<para>For example, to burn the image onto a CD at a speed of 4 and with verbose command output, run <command>cdrecord -v speed=4 <userinput>[image]</userinput></command> or <command>cdrskin -v speed=4 <userinput>[image]</userinput></command>, replacing <userinput>[image]</userinput> with the file name of the image you want to burn to the CD.</para>
<para>If there's only one optical disc drive on your system, it should be auto-detected. If not, find the device name using 'dmesg' or 'lsblk' and specify it using the 'dev' option. For example, if your optical device is <literal>/dev/sr0</literal>, run <command>cdrecord -v dev=/dev/sr0 speed=4 <userinput>[image]</userinput></command>.</para>
