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:
70</p>
71
72<ul>
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>
163

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.
244</p>
245

247Now take a look at the available installation media.

337Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
338networking. It contains a stage1 and several stage3 tarballs (optimized for the
339individual subarchitectures). For example the ppc variant of this CD is called

348after a succesfull Gentoo Installation. To install Gentoo, you only
349need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
350etc. 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

491If you have an OldWorld Mac the bootable portion of the livecd can't be used. 319
492Instead you need to download <uri

494MacOS installed on your system. You need to copy the <c>BootX Extension</c> from
495the unpacked archive-file into the <c>Extensions Folder</c> and make a new
496directory called <c>Linux Kernels</c> in the System Folder. In the next step you

498into the <c>Linux Kernels</c> directory. Then reboot the system and wait for
499BootX to load. After BootX loaded you still have to set up a few items. In the
500options dialog you need to check <c>Use Specified RAM Disk</c> and select the
501<c>initrd.img.gz</c> which you put in the <c>Linux Kernels</c> directory. The
502ramdisk size should be set to at least <c>32000</c>. Furthermore the kernel
503argument needs to be set to <c>rw init=/linuxrc cdroot</c>. Eventually you are

412<body>
413
414<p>
415If you have an OldWorld Mac the bootable portion of the livecd can't be used.
416The most simple solution is to use MacOS 9 or earlier to bootstrap into a Linux
417environment with a tool called BootX.
418</p>
419
420<p>
421First, download <uri link="http://penguinppc.org/projects/bootx/">BootX</uri>
422and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
423archive into <c>Extensions Folder</c> and the BootX App Control Panel into
424<c>Control Panels</c>, both of which are located in your MacOS System Folder.
425Next, create a folder called "Linux Kernels" in your System folder and copy the
426<c>ppc32</c> kernel from the CD to this folder. Finally, copy <c>ppc32.igz</c>
427from the Installation CD <path>boot</path> folder into the MacOS
428<c>System Folder</c>.
429</p>
430
431<p>
432To prepare BootX, start the BootX App Control Panel. First select the Options
433dialog and check <c>Use Specified RAM Disk</c> and select <c>ppc32.igz</c> from
434your System Folder. Continue back to the initial screen and ensure that the
435ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
436shown below:
437</p>
438
439<pre caption="BootX kernel arguments">
440cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0 nodevfs udev
441</pre>
442
443<note>
444The kernel parameters in the yaboot section above are also applicable here. You
445can append any of those options to the kernel arguments above.
446</note>
447
448<p>
449Check once more to make sure the settings are correct and then save the
450configuration. This saves typing just in case it doesn't boot or something is
451missing. Press the Linux button at the top of the window. If everything goes
452correctly, it should boot into the Installation CD. Continue with
