63<p>
64The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
65self-sustained Gentoo environment. They allow you to boot Linux from the CD.
66During the boot process your hardware is detected and the appropriate drivers
67are loaded. They are maintained by Gentoo developers.
28<p> 68</p>
29Check the following requirements before you 69
30continue with the Gentoo installation: 70<!--
71<p>
72All Installation CDs allow you to boot, set up networking, initialize your
73partitions and start installing Gentoo from the Internet. We currently provide
74two Installation CDs which are equally suitable to install Gentoo from, as long
75as you're planning on performing an Internet-based installation using the
76latest version of the available packages.
77</p>
78
79<p>
80If you wish to install Gentoo without a working Internet connection, please use
81the installation instructions described in the <uri
82link="2007.0/index.xml">Gentoo 2007.0 Handbooks</uri>.

53Still interested in trying out Gentoo? Well, then it is now time to
54choose the installation medium you want to use. Yes, you have the
55choice, no, they are not all equal, and yes, the result is always the same: a
56Gentoo base system.

74<title>The Three Stages</title>
75<body> 112<body>
76 113
77<p>
78Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
79The one you choose depends on how much of the system you want to compile
80yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
81build the entire system from scratch. The <e>stage2</e> tarball is used for
82building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
83The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
84been built for you.
85</p> 114<p>
86 115The Minimal Installation CD is called <c>install-alpha-minimal-2007.0.iso</c>
116and takes up only 65 MB of diskspace. You must use this Installation CD to
117install Gentoo, and you need a working Internet connection.
87<p> 118</p>
88Now what stage do you have to choose? 119<!--
89</p>
90
91<p>
92Starting from a <e>stage1</e> allows you to have total control over the
93optimization settings and optional build-time functionality that is
94initially enabled on your system. This makes <e>stage1</e> installs good for
95power users who know what they are doing. It is also a great
96installation method for those who would like to know more about the
97inner workings of Gentoo Linux.
98</p>
99
100<p>
101A <e>stage1</e> installation can only be performed when you have a working
102Internet connection.

193Linux, but also means that your base system will have the optimization
194settings that we chose for you (which to be honest, are good settings
195and were carefully chosen to enhance performance while maintaining
196stability). <e>stage3</e> is also required if you want to install Gentoo using
197prebuilt packages or without a network connection.

224Write down (or remember) what stage you want to use. You need this later when

226be interested to know that, if you decide to use different optimization settings
227after having installed Gentoo, you will be able to recompile your entire system
228with the new optimization settings.

180You might find a Package CD on one of our mirrors. This CD is not an
181Installation CD but an additional resource that can be exploited during a
182networkless installation. It contains prebuilt packages (also known as the GRP
183set) that allow you to easily and quickly install additional applications
184(such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless
185Gentoo installation.

189If you intend to use the Packages CD to quickly install additional software,
190make sure that you use the same subarchitecture as the stage3 tarball you use.

274Visit one of our <uri 225

282In case you wonder if your downloaded file is corrupted or not, you can 239In case you wonder if your downloaded file is corrupted or not, you can
283check its MD5 checksum and compare it with the MD5 checksum we provide (such as 240check its MD5 checksum and compare it with the MD5 checksum we provide (such as

293</p> 246<p>
247Another way to check the validity of the downloaded file is to use GnuPG to
248verify the cryptographic signature that we provide (the file ending with
