62Still interested in trying out Gentoo? Well, then it is now time to
63choose the installation medium you want to use. Yes, you have the
64choice, no, they are not all equal, and yes, the result is always the same: a
65Gentoo base system.
66</p>
67
68<p>
69The installation media we will describe are:

73<li>Gentoo's Minimal LiveCD</li>
74<li>Gentoo's Universal LiveCD</li>
75</ul>
76
77<p>
78Every single media has its advantages and disadvantages. We will list
79the pros and cons of every medium so you have all the information to
80make a justified decision. But before we continue, let's explain our
81three-stage installation.

87<title>The Three Stages</title>
88<body>
89
90<p>
91Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
92The one you choose depends on how much of the system you want to compile
93yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
94build the entire system from scratch. The <e>stage2</e> tarball is used for
95building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
96The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
97been built for you. As we will explain later, you can also install
98Gentoo without compiling anything (except your kernel and some optional
99packages). If you want this, you have to use a <e>stage3</e> tarball.
100</p>
101
102<p>
103Now what stage do you have to choose?
104</p>
105
106<p>
107Starting from a <e>stage1</e> allows you to have total control over the
108optimization settings and optional build-time functionality that is
109initially enabled on your system. This makes <e>stage1</e> installs good for
110power users who know what they are doing. It is also a great
111installation method for those who would like to know more about the
112inner workings of Gentoo Linux.
113</p>
114
115<p>
116A <e>stage1</e> installation can only be performed when you have a working
117Internet connection.

160is fine if you are happy with the optimization settings that we chose
161for your particular <e>stage2</e> tarball.
162</p>

206<p>
207Choosing to go with a <e>stage3</e> allows for the fastest install of Gentoo
208Linux, but also means that your base system will have the optimization
209settings that we chose for you (which to be honest, are good settings
210and were carefully chosen to enhance performance while maintaining
211stability). <e>stage3</e> is also required if you want to install Gentoo using
212prebuilt packages or without a network connection.

239Write down (or remember) what stage you want to use. You need this later when
240you decide what LiveCD (or other installation medium) you want to use. You might
241be interested to know that, if you decide to use different optimization settings
242after having installed Gentoo, you will be able to recompile your entire system
243with the new optimization settings.

117The Installation CDs that we currently provide are:
118</p>
273 119
120<ul>
121 <li>
122 The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable
123 CD which sole purpose is to boot the system, prepare the networking and
124 continue with the Gentoo installation.
125 </li>
126 <li>
127 The Universal Installation CD contains everything you need to install
128 Gentoo. It provides stage3 files for common architectures, source code
129 for the extra applications you need to choose from and, of course, the
130 installation instructions for your architecture.
131 </li>
132</ul>
133
134<p>
135Gentoo also provides a Package CD. This is not an Installation CD but an
136additional resource that you can exploit during the installation of your Gentoo
137system. It contains prebuilt packages (also known as the GRP set) that allow
138you to easily and quickly install additional applications (such as
139OpenOffice.org, KDE, GNOME, ...) immediately after the Gentoo installation and
140right before you update your Portage tree.
141</p>
142
143<p>
144The use of the Package CD is covered later in this document.

281This is a small, no-nonsense, bootable CD which sole purpose is to boot the

283does not contain any stages (or, in some cases, a single stage1 file),

323 183
324<p>
325Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
326networking. It contains a stage1 and several stage3 tarballs (optimized for the
327individual subarchitectures). For example the ppc variant of this CD is called
328<c>install-ppc-universal-2004.2.iso</c> and can be found in the
329<path>livecd</path> subdirectory.
330</p> 184<p>
331 185A stage3 tarball is an archive containing a minimal Gentoo environment,
186suitable to continue the Gentoo installation using the instructions in this
187manual. Previously, the Gentoo Handbook described the installation using one of
188three stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
189official installation method uses the stage3 tarball. If you are interested in
190performing a Gentoo installation using a stage1 or stage2 tarball, please read
191the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo
192Using a Stage1 or Stage2 Tarball?</uri>
332<p> 193</p>
333If you take a closer look on our mirrors, you will see 194
334that we provide <e>Gentoo Package CDs</e>. This CD (which isn't
335bootable) only contains precompiled packages and can be used to install software
336after a succesfull Gentoo Installation. To install Gentoo, you only
337need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
338etc. without having to compile every single one of them, you need the Packages
339CD too. For example the G4 (a subarchitecture of ppc) Packages CD is
340called <c>packages-g4-2004.2.iso</c> and can be found in the appropriate
341subdirectory (<path>g4/</path>).
342</p> 195<p>
343 196Stage3 tarballs can be downloaded from <path><keyval
197id="release-dir"/>current-stage3/</path> on any of the <uri
198link="/main/en/mirrors.xml">Official Gentoo Mirrors</uri> and are not provided
199on the LiveCD.
344<p> 200</p>
345You only need the Packages CD if you want to perform a stage3 with GRP
346installation.

468If you have an OldWorld Mac the bootable portion of the livecd can't be used. 290
469Instead you need to download <uri
470link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working
471MacOS installed on your system. You need to copy the <c>BootX Extension</c> from
472the unpacked archive-file into the <c>Extensions Folder</c> and make a new
473directory called <c>Linux Kernels</c> in the System Folder. In the next step you
474need to copy the <c>G3</c> kernel and the <c>initrd.img.gz</c> from the LiveCD
475into the <c>Linux Kernels</c> directory. Then reboot the system and wait for
476BootX to load. After BootX loaded you still have to set up a few items. In the
477options dialog you need to check <c>Use Secified RAM Disk</c> and select the
478<c>initrd.img.gz</c> which you put in the <c>Linux Kernels</c> directory. The
479ramdisk size should be set to at least <c>32000</c>. Furthermore the kernel
480argument needs to be set to <c>rw init=/linuxrc cdroot</c>. Eventually you are
481able to boot the LiveCD when you select Linux on Startup.

393<title>Alternative: Booting the Installation CD with BootX</title>
394<body>
395
396<p>
397If you have an OldWorld Mac the bootable portion of the livecd can't be used.
398The most simple solution is to use MacOS 9 or earlier to bootstrap into a Linux
399environment with a tool called BootX.
400</p>
401
402<p>
403First, download <uri link="http://penguinppc.org/bootloaders/bootx/">BootX</uri>
404and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
405archive into <c>Extensions Folder</c> and the BootX App Control Panel into
406<c>Control Panels</c>, both of which are located in your MacOS System Folder.
407Next, create a folder called "Linux Kernels" in your System folder and copy the
408<c>ppc32</c> kernel from the CD to this folder. Finally, copy <c>ppc32.igz</c>
409from the Installation CD <path>boot</path> folder into the MacOS
410<c>System Folder</c>.
411</p>
412
413<p>
414To prepare BootX, start the BootX App Control Panel. First select the Options
415dialog and check <c>Use Specified RAM Disk</c> and select <c>ppc32.igz</c> from
416your System Folder. Continue back to the initial screen and ensure that the
417ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
418shown below:
419</p>
420
421<pre caption="BootX kernel arguments">
422cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0
423</pre>
424
425<note>
426The kernel parameters in the yaboot section above are also applicable here. You
427can append any of those options to the kernel arguments above.
428</note>
429
430<p>
431Check once more to make sure the settings are correct and then save the
432configuration. This saves typing just in case it doesn't boot or something is
433missing. Press the Linux button at the top of the window. If everything goes
434correctly, it should boot into the Installation CD. Continue with

609When the LiveCD boots, it tries to detect all your hardware devices and
610loads the appropriate kernel modules to support your hardware. In the
611vast majority of cases, it does a very good job. However, in some cases, it may
612not auto-load the kernel modules you need. If the PCI auto-detection missed some
613of your system's hardware, you will have to load the appropriate kernel modules
614manually.

663security reasons), you need to create the necessary user accounts and change
664the root password.
665</p>
666
667<p>
668To change the root password, use the <c>passwd</c> utility:

676
677<p>
678To create a user account, we first enter their credentials, followed by
679its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
680In the next example, we create a user called &quot;john&quot;.
