76Gentoo Linux can be installed using one of three <e>stage</e> tarball files. 91Gentoo Linux can be installed using a <e>stage3</e> tarball file.
77A stage file is a tarball (compressed archive) that contains a minimal 92Such a tarball is an archive that contains a minimal environment from
78environment. 93which you can succesfully install Gentoo Linux onto your system.
94</p>
95
96<p>
97Installations using a stage1 or stage2 tarball file are not documented in the
98Gentoo Handbook - please read the <uri link="/doc/en/faq.xml#stage12">Gentoo
99FAQ</uri> on these matters.

105<title>Gentoo Universal Installation CD</title>
106<body>
107
108<p>
109An Installation CD is a bootable medium which contains a self-sustained Gentoo
110environment. It allows you to boot Linux from the CD. During the boot process
111your hardware is detected and the appropriate drivers are loaded. The Gentoo
112Installation CDs are maintained by Gentoo developers.
113</p>
114
115<p>
116There currently are two Installation CDs available:
79</p> 117</p>
80 118
81<ul> 119<ul>
82 <li> 120 <li>
83 A stage1 file contains nothing more than a compiler, Portage (Gentoo's 121 The Universal Installation CD contains everything you need to install
84 software management system) and a couple of packages on which the compiler 122 Gentoo. It provides stage3 files for common architectures, source code
85 or Portage depends. 123 for the extra applications you need to choose from and, of course, the
86 </li> 124 installation instructions for your architecture.
87 <li>
88 A stage2 file contains a so-called bootstrapped system, a minimal
89 environment from which one can start building all other necessary
90 applications that make a Gentoo environment complete.
91 </li>
92 <li>
93 A stage3 file contains a prebuilt minimal system which is almost fully
94 deployable. It only lacks a few applications where you, the Gentoo user,
95 needs to choose which one you want to install.
96 </li>
97</ul>
98
99<p>
100To help you decide what stage file you want to use, we have written down the
101major advantages and disadvantages of each stage file.

107<title>A Stage1 Approach</title>
108<body>
109
110<p>
111A <e>stage1</e> is used when you want to bootstrap and build the entire system
112from scratch.
113</p>
114
115<p>
116Starting from a stage1 allows you to have total control over the
117optimization settings and optional build-time functionality that is
118initially enabled on your system. This makes <e>stage1</e> installs good for
119power users who know what they are doing. It is also a great
120installation method for those who would like to know more about the
121inner workings of Gentoo Linux.

169A <e>stage2</e> is used for building the entire system from a bootstrapped
170"semi-compiled" state.
171</p>
172
173<p>
174Stage2 installs allow you to skip the bootstrap process; doing this
175is fine if you are happy with the optimization settings that we chose
176for your particular stage2 tarball.

219<title>A Stage3 Approach</title>
220<body>
221
222<p>
223A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
224built for you. You will only need to build a few packages of which we can't
225decide for you which one to choose.
226</p>
227
228<p>
229Choosing to go with a stage3 allows for the fastest install of Gentoo
230Linux, but also means that your base system will have the optimization
231settings that we chose for you (which to be honest, are good settings
232and were carefully chosen to enhance performance while maintaining
233stability). Stage3 is also required if you want to install Gentoo using
234prebuilt packages or without a network connection.

253You might be interested to know that, if you decide to use different

262<title>The Gentoo Installation CDs</title>
263<subsection>
264<title>Introduction</title>
265<body>
266
267<p>
268The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
269self-sustained Gentoo environment. They allow you to boot Linux from the CD.
270During the boot process your hardware is detected and the appropriate drivers
271are loaded. They are maintained by Gentoo developers.
272</p>
273
274<p>
275All Installation CDs allow you to boot, set up networking, initialize your
276partitions and start installing Gentoo from the Internet. We currently provide
277two Installation CDs which are equaly suitable to install Gentoo from, as long
278as you're planning on performing an Internet-based installation using the
279latest version of the available packages.
280</p>
281
282<p>
283If you wish to install Gentoo without a working Internet connection, please use
284the installation instructions described in the <uri
285link="2005.0/index.xml">Gentoo 2005.0 Handbooks</uri>.
286</p>
287
288<p>
289The two Installation CDs that we currently provide are:
290</p>
291
292<ul>
293 <li>
294 The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable
295 CD which sole purpose is to boot the system, prepare the networking and
296 continue with the Gentoo installation.
297 </li> 125 </li>
298 <li> 126 <li>
299 The Gentoo <e>Universal</e> Installation CD, a bootable CD with the same 127 The Minimal Installation CD contains only a minimal environment that allows
300 abilities as the Minimal Installation CD. Additionally, it contains a 128 you to boot up and configure your network so you can connect to the
301 stage1 and several stage3 tarballs (optimized for the individual 129 Internet. It does not contain any additional files and cannot be used
302 subarchitectures). 130 during the current installation approach.

307To help you decide which Installation CD you need, we have written down the 135Gentoo also provides a Package CD. This is not an Installation CD but an
308major advantages and disadvantages of each Installation CD. 136additional resource that you can exploit during the installation of your Gentoo
309</p> 137system. It contains prebuilt packages (also known as the GRP set) that allow
310 138you to easily and quickly install additional applications (such as
311</body> 139OpenOffice.org, KDE, GNOME, ...) immediately after the Gentoo installation and
312</subsection> 140right before you update your Portage tree.

318The Minimal Installation CD is called <c>install-ppc-minimal-2005.0.iso</c> and 142
319takes up only 52 MB of diskspace. You can use this Installation CD to install
320Gentoo, but always with a working Internet connection only.

406You have chosen to use a Gentoo Installation CD. We'll first start by
407downloading and burning the chosen Installation CD. We previously discussed
408the several available Installation CDs, but where can you find them?
409</p> 157<p>
410 158You can download the Universal Installation CD (and, if you want to, the
159Packages CD as well) from one of our <uri
160link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
161the <path><keyval id="release-dir"/>installcd</path> directory; the Package CDs
162are located in the <path><keyval id="release-dir"/>packagecd</path> directory.

172corrupted or not:

425check its MD5 checksum and compare it with the MD5 checksum we provide (such as 177 You can check its MD5 checksum and compare it with the MD5 checksum we
