17     Before we start, we first list what hardware requirements you need to
18     successfully install Gentoo on your box. This of course depends on your
19     architecture.

28     <p>
29     Check the following requirements before you
30     continue with the Gentoo installation:
31     </p>
32    
33     <ul>
34     <li>
35 dertobi123 1.17 You need at least 2 GB of free disk space
36 swift 1.1 </li>
37     <li>
38 dertobi123 1.17 If you do not use prebuilt packages, you need at least 300 MB of memory (RAM +
39 sejo 1.24 swap), if you do use prebuilt packages you need at least 64 MB of memory to boot the system.
40 swift 1.1 </li>
41     <li>
42 dertobi123 1.17 For the <e>PowerPC architecture</e>, you can install Gentoo/PPC on NewWorld machines
43 swift 1.1 having a Power or PowerPC microprocessor, including but not limited to G3, G4
44 dertobi123 1.17 or G5 powered Apple computers such as the iMac, the eMac, the iBook, the PowerBook,
45 pylon 1.21 Xserve, PowerMac, and bPlan's Pegasos II. We also provide limited
46 dertobi123 1.17 support for OldWorld systems, IBM (RS/6000, iSeries, pSeries, ...) and Amiga
47 swift 1.7 systems. Be sure to read up on the <uri link="/doc/en/gentoo-ppc-faq.xml">Gentoo

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

87     <title>The Three Stages</title>
88     <body>
89    
90     <p>
91     Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
92     The one you choose depends on how much of the system you want to compile
93     yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
94     build the entire system from scratch. The <e>stage2</e> tarball is used for
95     building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
96     The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
97     been built for you. As we will explain later, you can also install
98     Gentoo without compiling anything (except your kernel and some optional
99     packages). If you want this, you have to use a <e>stage3</e> tarball.
100     </p>
101    
102     <p>
103     Now what stage do you have to choose?
104     </p>
105    
106     <p>
107     Starting from a <e>stage1</e> allows you to have total control over the
108     optimization settings and optional build-time functionality that is
109     initially enabled on your system. This makes <e>stage1</e> installs good for
110     power users who know what they are doing. It is also a great
111     installation method for those who would like to know more about the
112     inner workings of Gentoo Linux.
113     </p>
114    
115 swift 1.10 <p>
116     A <e>stage1</e> installation can only be performed when you have a working
117     Internet connection.

206     <p>
207     Choosing to go with a <e>stage3</e> allows for the fastest install of Gentoo
208     Linux, but also means that your base system will have the optimization
209     settings that we chose for you (which to be honest, are good settings
210     and were carefully chosen to enhance performance while maintaining
211     stability). <e>stage3</e> is also required if you want to install Gentoo using
212 swift 1.9 prebuilt packages or without a network connection.

239     Write down (or remember) what stage you want to use. You need this later when
240     you decide what LiveCD (or other installation medium) you want to use. You might
241     be interested to know that, if you decide to use different optimization settings
242     after having installed Gentoo, you will be able to recompile your entire system
243     with the new optimization settings.

256 pylon 1.21 <note>
257     The Gentoo/PPC 2004.2 release is not official, so you will not find them on the
258 pylon 1.25 mirrors. All of our self-organised mirrors are currently down. The only chance
259     you can get the LiveCDs is via <uri
260     link="http://torrents.gentoo.org/torrents/">BitTorrent</uri>.
261 pylon 1.21 </note>
262    
263     <note>
264     It is known that the Pegasos II will not boot the 2004.2 LiveCD. Please use the
265     2004.1 LiveCD.
266     </note>
267    
268 swift 1.1 <p>
269     The <e>Gentoo LiveCDs</e> are bootable CDs which contain a
270     self-sustained Gentoo environment. They allow you to boot Linux from the CD.
271     During the boot process your hardware is detected and the appropriate drivers
272     are loaded. They are maintained by Gentoo developers.
273     </p>
274    
275     <p>
276     All LiveCDs allow you to boot, setup networking, initialize your
277     partitions and start installing Gentoo from the Internet. However, some
278     LiveCDs also contain all necessary source code so you are able to install
279     Gentoo without a working network configuration.
280     </p>
281    
282     <p>
283     Now what do these LiveCDs contain?

291    
292     <p>
293     This is a small, no-nonsense, bootable CD which sole purpose is to boot the
294     system, prepare the networking and continue with the Gentoo installation. It
295     does not contain any stages (or, in some cases, a single stage1 file),
296     source code or precompiled packages. For example the ppc variant of this
297 dertobi123 1.17 LiveCD can be found in the <path>livecd</path> subdirectory and is called
298     <c>install-ppc-minimal-2004.2.iso</c>.

333     <title>Gentoo's Universal LiveCD</title>
334     <body>
335    
336     <p>
337     Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
338     networking. It contains a stage1 and several stage3 tarballs (optimized for the
339     individual subarchitectures). For example the ppc variant of this CD is called
340 dertobi123 1.17 <c>install-ppc-universal-2004.2.iso</c> and can be found in the
341     <path>livecd</path> subdirectory.
342 swift 1.1 </p>
343    
344     <p>
345 swift 1.7 If you take a closer look on our mirrors, you will see
346     that we provide <e>Gentoo Package CDs</e>. This CD (which isn't
347 swift 1.1 bootable) only contains precompiled packages and can be used to install software
348     after a succesfull Gentoo Installation. To install Gentoo, you only
349     need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
350     etc. without having to compile every single one of them, you need the Packages
351     CD too. For example the G4 (a subarchitecture of ppc) Packages CD is
352 dertobi123 1.17 called <c>packages-g4-2004.2.iso</c> and can be found in the appropriate
353 swift 1.1 subdirectory (<path>g4/</path>).
354     </p>
355    
356 swift 1.11 <p>
357     You only need the Packages CD if you want to perform a stage3 with GRP
358     installation.

394     <subsection>
395     <title>Downloading and Burning the LiveCDs</title>
396     <body>
397    
398     <p>
399     You have chosen to use a Gentoo LiveCD (if not, then you are reading the
400     wrong section). We'll first start by downloading and burning the chosen
401     LiveCD. We previously discussed the several available LiveCDs, but where can you
402     find them?
403     </p>
404    
405     <p>
406     Visit one of our <uri
407     link="/main/en/mirrors.xml">mirrors</uri> and go to
408 dertobi123 1.17 <path>releases/ppc/2004.2/livecd</path>, which is
409 swift 1.1 the path where the LiveCD(s) of your choice are located. Inside that
410     directory you'll find so-called ISO-files. Those are full CD images
411     which you can write on a CD-R.
412     </p>
413    
414     <p>
415     In case you wonder if your downloaded file is corrupted or not, you can
416     check its MD5 checksum and compare it with the MD5 checksum we provide (such as
417 dertobi123 1.17 <path>install-ppc-minimal-2004.2.iso.md5</path>). You can check the MD5 checksum
418 swift 1.1 with the <c>md5sum</c> tool under Linux/Unix or <uri
419 neysx 1.16 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
420 swift 1.1 </p>
421    
422     <p>
423 dertobi123 1.17 As long as Mac OS X does not support <c>md5sum</c> you have to use the md5
424     capability of <c>openssl</c>. Therefore type in Terminal.app:
425 swift 1.12 </p>
426    
427 dertobi123 1.18 <pre caption="md5sum with the help of openssl">
428 dertobi123 1.17 $ <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 swift 1.12 </pre>
431    
432     <p>
433 dertobi123 1.17 Now compare this output with the appropriate file found on the server where you
434     downloaded the ISO (the file will end with .md5). If it is the same, the ISO
435     image downloaded correctly. Be sure you have not mounted it (e.g. with Disk
436     Copy) yet!
437 swift 1.12 </p>
438    
439 dertobi123 1.17 <p>
440     More information are available in our <uri

442     </p>
443 swift 1.12
444     <p>
445 swift 1.1 To burn the downloaded ISO(s), you have to select raw-burning. How you
446 swift 1.14 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
447 dertobi123 1.17 <c>k3b</c> here; more information can be found in our <uri
448     link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri> and the <uri

450 swift 1.1 </p>
451    
452     <ul>
453     <li>
454     With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace
455     <path>/dev/hdc</path> with your CD-RW drive's device path) followed
456     by the path to the ISO file :)
457     </li>
458     <li>
459 dertobi123 1.17 With k3b, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
460 bennyc 1.6 you can locate your ISO file within the 'Image to Burn' area. Finally click
461 swift 1.3 <c>Start</c>.

475 dertobi123 1.17 On NewWorld machines place the LiveCD in the CD-ROM and reboot the system. When
476     the system-start-bell sounds, simply hold down the 'C' until the CD loads.
477     </p>
478    
479     <p>
480     If you have an OldWorld Mac the bootable portion of the livecd can't be used.
481     Instead you need to download <uri
482     link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working
483     MacOS installed on your system. You need to copy the <c>BootX Extension</c> from
484     the unpacked archive-file into the <c>Extensions Folder</c> and make a new
485     directory called <c>Linux Kernels</c> in the System Folder. In the next step you
486     need to copy the <c>G3</c> kernel and the <c>initrd.img.gz</c> from the LiveCD
487     into the <c>Linux Kernels</c> directory. Then reboot the system and wait for
488     BootX to load. After BootX loaded you still have to set up a few items. In the
489 cam 1.19 options dialog you need to check <c>Use Specified RAM Disk</c> and select the
490 dertobi123 1.17 <c>initrd.img.gz</c> which you put in the <c>Linux Kernels</c> directory. The
491     ramdisk size should be set to at least <c>32000</c>. Furthermore the kernel
492     argument needs to be set to <c>rw init=/linuxrc cdroot</c>. Eventually you are
493     able to boot the LiveCD when you select Linux on Startup.

497     After the LiveCD loaded, you will be greeted by a friendly welcome message and a

502     At this prompt you are able to select a kernel for the subarchitecture you use.
503 dertobi123 1.17 We provide <c>G3</c>, <c>G4</c> and <c>G5</c>. All kernels are built with
504     support for multiple CPUs, but they will boot on single processor machines as
505     well.

524     you want to use. For instance <c>video=radeonfb:1280x1024@75</c>. If you are
525     uncertain what to choose, <c>ofonly</c> will most certainly work.

621 dertobi123 1.17 When the LiveCD boots, it tries to detect all your hardware devices and
622 swift 1.1 loads the appropriate kernel modules to support your hardware. In the
623 dertobi123 1.17 vast majority of cases, it does a very good job. However, in some cases, it may
624     not auto-load the kernel modules you need. If the PCI auto-detection missed some

626     manually.

673     If you plan on giving other people access to your installation

690 swift 1.5 To create a user account, we first enter their credentials, followed by
691 swift 1.1 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.

718     If you want to view the Gentoo Handbook (either from-CD or online) during the

756     If you want to allow other users to access your computer during the
757     Gentoo installation (perhaps because those users are going to help you
758     install Gentoo, or even do it for you), you need to create a user
