91Gentoo Linux can be installed using a <e>stage3</e> tarball file.
92Such a tarball is an archive that contains a minimal environment from
93which you can succesfully install Gentoo Linux onto your system.
32<p> 94</p>
33Check the following requirements before you 95
34continue with the Gentoo installation: 96<p>
97Installations using a stage1 or stage2 tarball file are not documented in the

105<title>Gentoo Universal Installation CD</title>
106<body>
107
108<p>
109An Installation CD is a bootable medium which contains a self-sustained Gentoo
110environment. It allows you to boot Linux from the CD. During the boot process
111your hardware is detected and the appropriate drivers are loaded. The Gentoo
112Installation CDs are maintained by Gentoo developers.
113</p>
114
115<p>
116There currently are two Installation CDs available:
35</p> 117</p>
36 118
37<ul> 119<ul>
38<li> 120 <li>
39 You need at least 2 GB of free disk space 121 The Universal Installation CD contains everything you need to install
122 Gentoo. It provides stage3 files for common architectures, source code
123 for the extra applications you need to choose from and, of course, the
124 installation instructions for your architecture.
40</li> 125 </li>
41<li> 126 <li>
42 If you do not use prebuilt packages, you need at least 300 MB of memory (RAM + 127 The Minimal Installation CD contains only a minimal environment that allows
43 swap), if you do use prebuilt packages you need at least 64 MB of memory to boot the system. 128 you to boot up and configure your network so you can connect to the
129 Internet. It does not contain any additional files and cannot be used
130 during the current installation approach.
44</li> 131 </li>
45<li>
46 For the <e>PowerPC architecture</e>, you can install Gentoo/PPC on NewWorld machines
47 having a Power or PowerPC microprocessor, including but not limited to G3, G4
48 or G5 powered Apple computers such as the iMac, the eMac, the iBook, the PowerBook,
49 Xserve, PowerMac, and bPlan's Pegasos II. We also provide limited
50 support for OldWorld systems, IBM (RS/6000, iSeries, pSeries, ...) and Amiga
51 systems. Be sure to read up on the <uri link="/doc/en/gentoo-ppc-faq.xml">Gentoo
52 PPC FAQ</uri> before you begin.
53</li>
54</ul> 132</ul>
55 133
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.

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> 157<p>
71 158You can download the Universal Installation CD (and, if you want to, the
159Packages CD as well) from one of our <uri
160link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
161the <path><keyval id="release-dir"/>installcd</path> directory; the Package CDs
162are located in the <path><keyval id="release-dir"/>packagecd</path> directory.
72<p> 163</p>
73The installation media we will describe are: 164
165<p>
166Inside those directories you'll find ISO files. Those are full CD images which
167you can write on a CD-R.
168</p>
169
170<p>
171After downloading the file, you can verify its integrity to see if it is
172corrupted or not:

77<li>Gentoo's Minimal LiveCD</li> 176 <li>
78<li>Gentoo's Universal LiveCD</li> 177 You can check its MD5 checksum and compare it with the MD5 checksum we
178 provide (for instance with the <c>md5sum</c> tool under Linux/Unix or
179 <uri link="http://www.etree.org/md5com.html">md5sum</uri> for Windows).
180 Verifying MD5 checksums with Mac OS X is described in the <uri
181 link="/doc/en/gentoo-ppc-faq.xml#doc_chap1">Gentoo PPC FAQ</uri>.
182 </li>
183 <li>
184 You can verify the cryptographic signature that we provide. You need to
185 obtain the public key we use (0x17072058) before you proceed though.

82Every single media has its advantages and disadvantages. We will list 190To fetch our public key using the GnuPG application, run the following command:
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

91<title>The Three Stages</title>
92<body>
93
94<p> 191</p>
95Gentoo Linux can be installed using one of three <e>stage</e> tarball files. 192
96The one you choose depends on how much of the system you want to compile 193<pre caption="Obtaining the public key">
97yourself. The <e>stage1</e> tarball is used when you want to bootstrap and 194$ <i>gpg --keyserver subkeys.pgp.net --recv-keys 0x17072058</i>
98build the entire system from scratch. The <e>stage2</e> tarball is used for 195</pre>
99building the entire system from a bootstrapped &quot;semi-compiled&quot; state. 196
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> 197<p>
105 198Now verify the signature:
106<p> 199</p>
107Now what stage do you have to choose? 200

108</p> 203</pre>
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.

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.

261The Gentoo/PPC 2004.2 release is not official, so you will not find them on the
262mirrors. All of our self-organised mirrors are currently down. The only chance
263you can get the LiveCDs is via <uri
264link="http://torrents.gentoo.org/torrents/">BitTorrent</uri>.
265</note>
266
267<note>
268It is known that the Pegasos II will not boot the 2004.2 LiveCD. Please use the
2692004.1 LiveCD.
270</note>
271
272<p>
273The <e>Gentoo LiveCDs</e> are bootable CDs which contain a
274self-sustained Gentoo environment. They allow you to boot Linux from the CD.
275During the boot process your hardware is detected and the appropriate drivers
276are loaded. They are maintained by Gentoo developers.
277</p>
278
279<p>
280All LiveCDs allow you to boot, set up networking, initialize your
281partitions and start installing Gentoo from the Internet. However, some
282LiveCDs also contain all necessary source code so you are able to install
283Gentoo without a working network configuration.

299does not contain any stages (or, in some cases, a single stage1 file),

340<p>
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
344<c>install-ppc-universal-2004.2.iso</c> and can be found in the
345<path>livecd</path> subdirectory.
346</p>
347
348<p>
349If you take a closer look on our mirrors, you will see
350that we provide <e>Gentoo Package CDs</e>. This CD (which isn't
351bootable) only contains precompiled packages and can be used to install software
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
355CD too. For example the G4 (a subarchitecture of ppc) Packages CD is
356called <c>packages-g4-2004.2.iso</c> and can be found in the appropriate
357subdirectory (<path>g4/</path>).

399<title>Downloading and Burning the LiveCDs</title>
400<body>
401
402<p>
403You have chosen to use a Gentoo LiveCD (if not, then you are reading the
404wrong section). We'll first start by downloading and burning the chosen
405LiveCD. We previously discussed the several available LiveCDs, but where can you
406find them?
407</p>
408
409<p>
410Visit one of our <uri
411link="/main/en/mirrors.xml">mirrors</uri> and go to
412<path>releases/ppc/2004.2/livecd</path>, which is
413the path where the LiveCD(s) of your choice are located. Inside that
414directory you'll find so-called ISO-files. Those are full CD images
415which you can write on a CD-R.
416</p>
417
418<p>
419In case you wonder if your downloaded file is corrupted or not, you can
420check its MD5 checksum and compare it with the MD5 checksum we provide (such as
421<path>install-ppc-minimal-2004.2.iso.md5</path>). You can check the MD5 checksum
422with the <c>md5sum</c> tool under Linux/Unix or <uri
423link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
424</p>
425
426<p>
427As long as Mac OS X does not support <c>md5sum</c> you have to use the md5
428capability of <c>openssl</c>. Therefore type in Terminal.app:
429</p>
430
431<pre caption="md5sum with the help of openssl">
432$ <i>openssl md5 /path/to/iso</i>
433<comment>This could take some time depending of the size of the ISO and your CPU</comment>
434</pre>
435
436<p>
437Now compare this output with the appropriate file found on the server where you
438downloaded the ISO (the file will end with .md5). If it is the same, the ISO
439image downloaded correctly. Be sure you have not mounted it (e.g. with Disk

495If you have an OldWorld Mac the bootable portion of the livecd can't be used. 235
496Instead you need to download <uri
497link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working
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
501need to copy the <c>G3</c> kernel and the <c>initrd.img.gz</c> from the LiveCD
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.

338<title>Alternative: Booting the Installation CD with BootX</title>
339<body>
340
341<p>
342If you have an OldWorld Mac the bootable portion of the livecd can't be used.
343The most simple solution is to use MacOS 9 or earlier to bootstrap into a Linux
344environment with a tool called BootX.
345</p>
346
347<p>
348First, download <uri link="http://penguinppc.org/bootloaders/bootx/">BootX</uri>
349and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
350archive into <c>Extensions Folder</c> and the BootX App Control Panel into
351<c>Control Panels</c>, both of which are located in your MacOS System Folder.
352Next, create a folder called "Linux Kernels" in your System folder and copy the
353<c>apple</c> kernel from the CD to this folder. Finally, copy <c>apple.igz</c>
354from the Installation CD <path>boot</path> folder into the MacOS
355<c>System Folder</c>.
356</p>
357
358<p>
359To prepare BootX, start the BootX App Control Panel. First select the Options
360dialog and check <c>Use Specified RAM Disk</c> and select <c>apple.igz</c> from
361your System Folder. Continue back to the initial screen and ensure that the
362ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
363shown below:
364</p>
365
366<pre caption="BootX kernel arguments">
367cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0
368</pre>
369
370<note>
371The kernel parameters in the yaboot section above are also applicable here. You
372can append any of those options to the kernel arguments above.
373</note>
374
375<p>
376Check once more to make sure the settings are correct and then save the
377configuration. This saves typing just in case it doesn't boot or something is
378missing. Press the Linux button at the top of the window. If everything goes
379correctly, it should boot into the Installation CD. Continue with

636When the LiveCD boots, it tries to detect all your hardware devices and
637loads the appropriate kernel modules to support your hardware. In the
638vast majority of cases, it does a very good job. However, in some cases, it may
639not auto-load the kernel modules you need. If the PCI auto-detection missed some
640of your system's hardware, you will have to load the appropriate kernel modules
641manually.
642</p>
643
644<p>
645In the next example we try to load the <c>8139too</c> module (support for
646certain kinds of network interfaces):

705To create a user account, we first enter their credentials, followed by
706its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
