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

69	The installation media we will describe are:

73	<li>Gentoo's Minimal LiveCD</li>
74	<li>Gentoo's Universal LiveCD</li>

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

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

146
147	<p>
148	<e>Stage2</e> installs allow you to skip the bootstrap process and doing this
149	is fine if you are happy with the optimization settings that we chose
150	for your particular <e>stage2</e> tarball.

181	</tr>
182	</table>
183
184	<p>
185	Choosing to go with a <e>stage3</e> allows for the fastest install of Gentoo
186	Linux, but also means that your base system will have the optimization
187	settings that we chose for you (which to be honest, are good settings
188	and were carefully chosen to enhance performance while maintaining
189	stability). <e>stage3</e> is also required if you want to install Gentoo using
190	prebuilt packages.

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

		133
		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.

299	Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
300	networking. It contains a stage1 and several stage3 tarballs (optimized for the
301	individual subarchitectures). For example the ppc variant of this CD is called
302	<c>install-ppc-universal-2004.0.iso</c> and can be found in the
303	<path>universal</path> subdirectory.
304	</p>	184	<p>
305		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>
306	<p>	193	</p>
307	If you take a closer look into our <path>livecd</path> directory you will see	194
308	that some architectures provide <e>Gentoo Package CDs</e>. This CD (which isn't
309	bootable) only contains precompiled packages and can be used to install software
310	after a succesfull Gentoo Installation. To install Gentoo, you only
311	need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
312	etc. without having to compile every single one of them, you need the Packages
313	CD too. For example the G4 (a subarchitecture of ppc) Packages CD is
314	called <c>packages-g4-2004.0.iso</c> and can be found in the appropriate
315	subdirectory (<path>g4/</path>).

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

533	When the Live CD boots, it tries to detect all your hardware devices and
534	loads the appropriate kernel modules to support your hardware. In the

536	SPARC LiveCDs don't even do autodetection), it may not auto-load the kernel
537	modules you need. If the PCI auto-detection missed some of your system's
538	hardware, you will have to load the appropriate kernel modules manually.
