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.

163<e>Stage2</e> installs allow you to skip the bootstrap process and doing this
164is fine if you are happy with the optimization settings that we chose
165for your particular <e>stage2</e> tarball.
166</p>
167

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.

260<note>
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

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.

339
340<p> 113</p>
341Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without 114
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> 115<p>
347 116There currently are two Installation CDs available:
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>).
358</p>
359

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
440Copy) yet!
441</p>
442
443<p>
444More information are available in our <uri
445link="/doc/en/gentoo-ppc-faq.xml">PPC FAQ.</uri>
446</p>
447
448<p>
449To burn the downloaded ISO(s), you have to select raw-burning. How you
450do this is highly program-dependent. We will discuss <c>cdrecord</c>,
451<c>k3b</c> and the MacOS burning possibilities here; more information can
452be found in our <uri link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri> and
453the <uri link="/doc/en/gentoo-ppc-faq.xml">PPC FAQ</uri>.

455 118
456<ul> 119<ul>
457 <li> 120 <li>
458 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace 121 The Universal Installation CD contains everything you need to install
459 <path>/dev/hdc</path> with your CD-RW drive's device path) followed 122 Gentoo. It provides stage3 files for common architectures, source code
460 by the path to the ISO file :) 123 for the extra applications you need to choose from and, of course, the
124 installation instructions for your architecture.
461 </li> 125 </li>
462 <li> 126 <li>
127 The Minimal Installation CD contains only a minimal environment that allows
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.
131 </li>
132</ul>
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.

495If you have an OldWorld Mac the bootable portion of the livecd can't be used. 236
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.

329<body>
330
331<p>
332If you have an OldWorld Mac the bootable portion of the livecd can't be used.
333The most simple solution is to use MacOS 9 or earlier to bootstrap into a Linux
334environment with a tool called BootX.
335</p>
336
337<p>
338First, download <uri link="http://penguinppc.org/projects/bootx/">BootX</uri>
339and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
340archive into <c>Extensions Folder</c> and the BootX App Control Panel into
341<c>Control Panels</c>, both of which are located in your MacOS System Folder.
342Next, create a folder called "Linux Kernels" in your System folder and copy the
343<c>apple</c> kernel from the CD to this folder. Finally, copy <c>apple.igz</c>
344from the Installation CD <path>boot</path> folder into the MacOS
345<c>System Folder</c>.
346</p>
347
348<p>
349To prepare BootX, start the BootX App Control Panel. First select the Options
350dialog and check <c>Use Specified RAM Disk</c> and select <c>apple.igz</c> from
351your System Folder. Continue back to the initial screen and ensure that the
352ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
353shown below:
354</p>
355
356<pre caption="BootX kernel arguments">
357cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0
358</pre>
359
360<note>
361The kernel parameters in the yaboot section above are also applicable here. You
362can append any of those options to the kernel arguments above.
363</note>
364
365<p>
366Check once more to make sure the settings are correct and then save the
367configuration. This saves typing just in case it doesn't boot or something is
368missing. Press the Linux button at the top of the window. If everything goes
369correctly, it should boot into the Installation CD. Continue with
