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

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

164is fine if you are happy with the optimization settings that we chose
165for your particular <e>stage2</e> tarball.
166</p>
167

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

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

341Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
342networking. It contains a stage1 and several stage3 tarballs (optimized for the
343individual subarchitectures). For example the ppc variant of this CD is called

352after a succesfull Gentoo Installation. To install Gentoo, you only
353need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
354etc. without having to compile every single one of them, you need the Packages

203Installation CD but an additional resource that can be exploited during a

222A stage3 tarball is an archive containing a minimal Gentoo environment, suitable
223to continue the Gentoo installation using the instructions in this manual.
224Previously, the Gentoo Handbook described the installation using one of three
225stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
226official installation method uses the stage3 tarball. If you are interested in
227performing a Gentoo installation using a stage1 or stage2 tarball, please read

496Instead you need to download <uri

498MacOS installed on your system. You need to copy the <c>BootX Extension</c> from
499the unpacked archive-file into the <c>Extensions Folder</c> and make a new
500directory called <c>Linux Kernels</c> in the System Folder. In the next step you

502into the <c>Linux Kernels</c> directory. Then reboot the system and wait for
503BootX to load. After BootX loaded you still have to set up a few items. In the
504options dialog you need to check <c>Use Specified RAM Disk</c> and select the
505<c>initrd.img.gz</c> which you put in the <c>Linux Kernels</c> directory. The
506ramdisk size should be set to at least <c>32000</c>. Furthermore the kernel
507argument needs to be set to <c>rw init=/linuxrc cdroot</c>. Eventually you are
508able to boot the LiveCD when you select Linux on Startup.

401<title>Alternative: Booting the Installation CD with BootX</title>
402<body>
403
404<p>
405If you have an OldWorld Mac the bootable portion of the livecd can't be used.
406The most simple solution is to use MacOS to bootstrap into a Linux environment
407with a tool called BootX.
408</p>
409
410<p>
411First, download <uri link="http://penguinppc.org/projects/bootx/">BootX</uri>
412and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
413archive into <c>Extensions Folder</c> and the BootX App Control Panel into
414<c>Control Panels</c>, both of which are located in your MacOS System Folder.
415Next, create a folder called "Linux Kernels" in your System folder and copy the
416<c>ppc32</c> kernel from the CD to this folder. Finally, copy <c>ppc32.igz</c>
417from the Installation CD <path>boot</path> folder into the MacOS
418<c>System Folder</c>.
419</p>
420
421<p>
422To prepare BootX, start the BootX App Control Panel. First select the Options
423dialog and check <c>Use Specified RAM Disk</c> and select <c>ppc32.igz</c> from
424your System Folder. Continue back to the initial screen and ensure that the
425ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
426shown below:
427</p>
428
429<pre caption="BootX kernel arguments">
430cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0 nodevfs udev
431</pre>
432
433<note>
434The kernel parameters in the yaboot section above are also applicable here. You
435can append any of those options to the kernel arguments above.
436</note>
437
438<p>
439Check once more to make sure the settings are correct and then save the
440configuration. This saves typing just in case it doesn't boot or something is
441missing. Press the Linux button at the top of the window. If everything goes
442correctly, it should boot into the Installation CD. Continue with
