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.
28<p> 94</p>
29Check the following requirements before you 95
30continue with the Gentoo installation: 96<p>
97Installations using a stage1 or stage2 tarball file are not documented in the
98Gentoo Handbook - please read the <uri link="/doc/en/faq.xml#stage12">Gentoo

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:
31</p> 117</p>
32 118
33<ul> 119<ul>
34<li> 120 <li>
35 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.
36</li> 125 </li>
37<li> 126 <li>
38 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
39 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.
40</li> 131 </li>
41<li>
42 For the <e>PowerPC architecture</e>, you can install Gentoo/PPC on NewWorld machines
43 having a Power or PowerPC microprocessor, including but not limited to G3, G4
44 or G5 powered Apple computers such as the iMac, the eMac, the iBook, the PowerBook,
45 Xserve, PowerMac, and bPlan's Pegasos II. We also provide limited
46 support for OldWorld systems, IBM (RS/6000, iSeries, pSeries, ...) and Amiga
47 systems. Be sure to read up on the <uri link="/doc/en/gentoo-ppc-faq.xml">Gentoo
48 PPC FAQ</uri> before you begin.
49</li>
50</ul> 132</ul>
51 133
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.

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> 157<p>
67 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.
68<p> 163</p>
69The 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:

74<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

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.

78Every single media has its advantages and disadvantages. We will list 190To fetch our public key using the GnuPG application, run the following command:
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

87<title>The Three Stages</title>
88<body>
89
90<p> 191</p>
91Gentoo Linux can be installed using one of three <e>stage</e> tarball files. 192
92The one you choose depends on how much of the system you want to compile 193<pre caption="Obtaining the public key">
93yourself. The <e>stage1</e> tarball is used when you want to bootstrap and 194$ <i>gpg --keyserver subkeys.pgp.net --recv-keys 0x17072058</i>
94build the entire system from scratch. The <e>stage2</e> tarball is used for 195</pre>
95building the entire system from a bootstrapped &quot;semi-compiled&quot; state. 196
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> 197<p>
101 198Now verify the signature:
102<p> 199</p>
103Now what stage do you have to choose? 200

104</p> 203</pre>
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.

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.

256<note>
257The Gentoo/PPC 2004.2 release is not official, so you will not find them on the
258mirrors. All of our self-organised mirrors are currently down. The only chance
259you can get the LiveCDs is via <uri
260link="http://torrents.gentoo.org/torrents/">BitTorrent</uri>.
261</note>
262
263<note>
264It is known that the Pegasos II will not boot the 2004.2 LiveCD. Please use the
2652004.1 LiveCD.
266</note>
267
268<p>
269The <e>Gentoo LiveCDs</e> are bootable CDs which contain a
270self-sustained Gentoo environment. They allow you to boot Linux from the CD.
271During the boot process your hardware is detected and the appropriate drivers
272are loaded. They are maintained by Gentoo developers.
273</p>
274
275<p>
276All LiveCDs allow you to boot, set up networking, initialize your
277partitions and start installing Gentoo from the Internet. However, some
278LiveCDs also contain all necessary source code so you are able to install
279Gentoo without a working network configuration.

295does not contain any stages (or, in some cases, a single stage1 file),

335
336<p>
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
340<c>install-ppc-universal-2004.2.iso</c> and can be found in the
341<path>livecd</path> subdirectory.
342</p>
343
344<p>
345If you take a closer look on our mirrors, you will see
346that we provide <e>Gentoo Package CDs</e>. This CD (which isn't
347bootable) only contains precompiled packages and can be used to install software
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
351CD too. For example the G4 (a subarchitecture of ppc) Packages CD is
352called <c>packages-g4-2004.2.iso</c> and can be found in the appropriate
353subdirectory (<path>g4/</path>).

395<title>Downloading and Burning the LiveCDs</title>
396<body>
397
398<p>
399You have chosen to use a Gentoo LiveCD (if not, then you are reading the
400wrong section). We'll first start by downloading and burning the chosen
401LiveCD. We previously discussed the several available LiveCDs, but where can you
402find them?
403</p>
404
405<p>
406Visit one of our <uri
407link="/main/en/mirrors.xml">mirrors</uri> and go to
408<path>releases/ppc/2004.2/livecd</path>, which is
409the path where the LiveCD(s) of your choice are located. Inside that
410directory you'll find so-called ISO-files. Those are full CD images
411which you can write on a CD-R.
412</p>
413
414<p>
415In case you wonder if your downloaded file is corrupted or not, you can
416check its MD5 checksum and compare it with the MD5 checksum we provide (such as
417<path>install-ppc-minimal-2004.2.iso.md5</path>). You can check the MD5 checksum
418with the <c>md5sum</c> tool under Linux/Unix or <uri
419link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
420</p>
421
422<p>
423As long as Mac OS X does not support <c>md5sum</c> you have to use the md5
424capability of <c>openssl</c>. Therefore type in Terminal.app:
425</p>
426
427<pre caption="md5sum with the help of openssl">
428$ <i>openssl md5 /path/to/iso</i>
429<comment>This could take some time depending of the size of the ISO and your CPU</comment>
430</pre>
431
432<p>
433Now compare this output with the appropriate file found on the server where you
434downloaded the ISO (the file will end with .md5). If it is the same, the ISO
435image downloaded correctly. Be sure you have not mounted it (e.g. with Disk
436Copy) yet!
437</p>
438

491If you have an OldWorld Mac the bootable portion of the livecd can't be used. 235
492Instead you need to download <uri
493link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working
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
497need to copy the <c>G3</c> kernel and the <c>initrd.img.gz</c> from the LiveCD
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
504able 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

632When the LiveCD boots, it tries to detect all your hardware devices and
633loads the appropriate kernel modules to support your hardware. In the
634vast majority of cases, it does a very good job. However, in some cases, it may
635not auto-load the kernel modules you need. If the PCI auto-detection missed some
636of your system's hardware, you will have to load the appropriate kernel modules
637manually.

701To create a user account, we first enter their credentials, followed by
702its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
