66	Still interested in trying out Gentoo? Well, then it is now time to
67	choose the installation medium you want to use. Yes, you have the
68	choice, no, they are not all equal, and yes, the result is always the same: a
69	Gentoo base system.
70	</p>
71
72	<p>
73	The installation media we will describe are:
74	</p>
75
76	<ul>
77	<li>Gentoo's Minimal LiveCD</li>
78	<li>Gentoo's Universal LiveCD</li>
79	</ul>
80
81	<p>
82	Every single media has its advantages and disadvantages. We will list
83	the pros and cons of every medium so you have all the information to
84	make a justified decision. But before we continue, let's explain our
85	three-stage installation.

90	<subsection>
91	<title>The Three Stages</title>
92	<body>
93
94	<p>
95	Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
96	The one you choose depends on how much of the system you want to compile
97	yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
98	build the entire system from scratch. The <e>stage2</e> tarball is used for
99	building the entire system from a bootstrapped "semi-compiled" state.
100	The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
101	been built for you. As we will explain later, you can also install
102	Gentoo without compiling anything (except your kernel and some optional
103	packages). If you want this, you have to use a <e>stage3</e> tarball.
104	</p>
105
106	<p>
107	Now what stage do you have to choose?
108	</p>
109
110	<p>
111	Starting from a <e>stage1</e> allows you to have total control over the
112	optimization settings and optional build-time functionality that is
113	initially enabled on your system. This makes <e>stage1</e> installs good for
114	power users who know what they are doing. It is also a great
115	installation method for those who would like to know more about the
116	inner workings of Gentoo Linux.
117	</p>
118
119	<p>
120	A <e>stage1</e> installation can only be performed when you have a working
121	Internet connection.

161

163	<e>Stage2</e> installs allow you to skip the bootstrap process and doing this
164	is fine if you are happy with the optimization settings that we chose
165	for your particular <e>stage2</e> tarball.
166	</p>
167
168	<p>

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

243	Write down (or remember) what stage you want to use. You need this later when
244	you decide what LiveCD (or other installation medium) you want to use. You might
245	be interested to know that, if you decide to use different optimization settings
246	after having installed Gentoo, you will be able to recompile your entire system
247	with the new optimization settings.
248	</p>
249
250	<p>
251	Now take a look at the available installation media.

		134	<p>
		135	Gentoo also provides a Package CD. This is not an Installation CD but an
		136	additional resource that you can exploit during the installation of your Gentoo
		137	system. It contains prebuilt packages (also known as the GRP set) that allow
		138	you to easily and quickly install additional applications (such as
		139	OpenOffice.org, KDE, GNOME, ...) immediately after the Gentoo installation and
		140	right before you update your Portage tree.

341	Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
342	networking. It contains a stage1 and several stage3 tarballs (optimized for the
343	individual subarchitectures). For example the ppc variant of this CD is called
344	<c>install-ppc-universal-2004.2.iso</c> and can be found in the
345	<path>livecd</path> subdirectory.
346	</p>	184	<p>
347		185	A stage3 tarball is an archive containing a minimal Gentoo environment,
		186	suitable to continue the Gentoo installation using the instructions in this
		187	manual. Previously, the Gentoo Handbook described the installation using one of
		188	three stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
		189	official installation method uses the stage3 tarball. If you are interested in
		190	performing a Gentoo installation using a stage1 or stage2 tarball, please read
		191	the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo
		192	Using a Stage1 or Stage2 Tarball?</uri>
348	<p>	193	</p>
349	If you take a closer look on our mirrors, you will see	194
350	that we provide <e>Gentoo Package CDs</e>. This CD (which isn't
351	bootable) only contains precompiled packages and can be used to install software
352	after a succesfull Gentoo Installation. To install Gentoo, you only
353	need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
354	etc. without having to compile every single one of them, you need the Packages
355	CD too. For example the G4 (a subarchitecture of ppc) Packages CD is
356	called <c>packages-g4-2004.2.iso</c> and can be found in the appropriate
357	subdirectory (<path>g4/</path>).
358	</p>	195	<p>
359		196	Stage3 tarballs can be downloaded from <path><keyval
		197	id="release-dir"/>current-stage3/</path> on any of the <uri
		198	link="/main/en/mirrors.xml">Official Gentoo Mirrors</uri> and are not provided
		199	on the LiveCD.
360	<p>	200	</p>
361	You only need the Packages CD if you want to perform a stage3 with GRP
362	installation.

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

662	test the performance of your disk (execute it several times to get a
663	more precise impression):
664	</p>
665
666	<pre caption="Testing disk performance">
667	# <i>hdparm -tT /dev/hda</i>
668	</pre>
669
670	<p>
671	To tweak, you can use any of the following examples (or experiment
672	yourself) which use <path>/dev/hda</path> as disk (substitute with your
673	disk):
674	</p>
675
676	<pre caption="Tweaking hard disk performance">
677	<comment>Activate DMA:</comment> # <i>hdparm -d 1 /dev/hda</i>
678	<comment>Activate DMA + Safe Performance-enhancing Options:</comment> # <i>hdparm -d 1 -A 1 -m 16 -u 1 -a 64 /dev/hda</i>

686
687	<p>
688	If you plan on giving other people access to your installation
689	environment or you want to chat using <c>irssi</c> without root privileges (for
690	security reasons), you need to create the necessary user accounts and change
691	the root password.
692	</p>
693
694	<p>
695	To change the root password, use the <c>passwd</c> utility:
696	</p>
697
698	<pre caption="Changing the root password">
699	# <i>passwd</i>
700	New password: <comment>(Enter your new password)</comment>
701	Re-enter password: <comment>(Re-enter your password)</comment>
702	</pre>
703
704	<p>
705	To create a user account, we first enter their credentials, followed by
706	its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
707	In the next example, we create a user called "john".
708	</p>
709
710	<pre caption="Creating a user account">
711	# <i>useradd -m -G users john</i>
712	# <i>passwd john</i>
713	New password: <comment>(Enter john's password)</comment>
714	Re-enter password: <comment>(Re-enter john's password)</comment>
715	</pre>
716
717	<p>
718	You can change your user id from root to the newly created user by using
719	<c>su</c>:

729	<title>Optional: Viewing Documentation while Installing</title>
730	<body>
731
732	<p>
733	If you want to view the Gentoo Handbook (either from-CD or online) during the
734	installation, make sure you have created a user account (see <uri
735	link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
736	go to a new terminal and log in.
737	</p>
738
739	<p>
740	If you want to view the documentation on the CD you can immediately run
741	<c>links2</c> to read it:
742	</p>
743
744	<pre caption="Viewing the on-CD documentation">
745	# <i>links2 /mnt/cdrom/docs/html/index.html</i>
746	</pre>
747
748	<p>
749	However, it is preferred that you use the online Gentoo Handbook as it will be
750	more recent than the one provided on the CD. You can view it using <c>links2</c>
751	as well, but only after having completed the <e>Configuring your Network</e>
752	chapter (otherwise you won't be able to go on the Internet to view the
753	document):
754	</p>
755
756	<pre caption="Viewing the Online Documentation">
757	# <i>links2 http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml</i>
758	</pre>
759
760	<p>
761	You can go back to your original terminal by pressing <c>Alt-F1</c>.

767	<title>Optional: Starting the SSH Daemon</title>
768	<body>
769
770	<p>
771	If you want to allow other users to access your computer during the
772	Gentoo installation (perhaps because those users are going to help you
773	install Gentoo, or even do it for you), you need to create a user
774	account for them and perhaps even provide them with your root password
775	(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
776	</p>
777
778	<p>
779	To fire up the SSH daemon, execute the following command:
780	</p>
781
782	<pre caption="Starting the SSH daemon">
783	# <i>/etc/init.d/sshd start</i>
784	</pre>
785
786	<p>
787	To be able to use sshd, you first need to set up your networking. Continue with
788	the chapter on <uri link="?part=1&chap=3">Configuring your Network</uri>.
