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 swift 1.1 swap)
40     </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     Xserve, PowerMac, and bPlan's Pegasos I and II. We also provide limited
46     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.

159     <e>Stage2</e> installs allow you to skip the bootstrap process and doing this

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.
244     </p>
245

247     Now take a look at the available installation media.

253     <title>Gentoo LiveCDs</title>
254     <body>
255    
256     <p>
257     The <e>Gentoo LiveCDs</e> are bootable CDs which contain a
258     self-sustained Gentoo environment. They allow you to boot Linux from the CD.
259     During the boot process your hardware is detected and the appropriate drivers
260     are loaded. They are maintained by Gentoo developers.
261     </p>
262    
263     <p>
264     All LiveCDs allow you to boot, setup networking, initialize your
265     partitions and start installing Gentoo from the Internet. However, some
266     LiveCDs also contain all necessary source code so you are able to install
267     Gentoo without a working network configuration.
268     </p>
269    
270     <p>
271     Now what do these LiveCDs contain?

277     <title>Gentoo's Minimal LiveCD</title>

279    
280     <p>
281     This is a small, no-nonsense, bootable CD which sole purpose is to boot the
282     system, prepare the networking and continue with the Gentoo installation. It
283     does not contain any stages (or, in some cases, a single stage1 file),
284     source code or precompiled packages. For example the ppc variant of this
285 dertobi123 1.17 LiveCD can be found in the <path>livecd</path> subdirectory and is called
286     <c>install-ppc-minimal-2004.2.iso</c>.

321     <title>Gentoo's Universal LiveCD</title>
322     <body>
323    
324     <p>
325     Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
326     networking. It contains a stage1 and several stage3 tarballs (optimized for the
327     individual subarchitectures). For example the ppc variant of this CD is called
328 dertobi123 1.17 <c>install-ppc-universal-2004.2.iso</c> and can be found in the
329     <path>livecd</path> subdirectory.
330 swift 1.1 </p>
331    
332     <p>
333 swift 1.7 If you take a closer look on our mirrors, you will see
334     that we provide <e>Gentoo Package CDs</e>. This CD (which isn't
335 swift 1.1 bootable) only contains precompiled packages and can be used to install software
336     after a succesfull Gentoo Installation. To install Gentoo, you only
337     need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
338     etc. without having to compile every single one of them, you need the Packages
339     CD too. For example the G4 (a subarchitecture of ppc) Packages CD is
340 dertobi123 1.17 called <c>packages-g4-2004.2.iso</c> and can be found in the appropriate
341 swift 1.1 subdirectory (<path>g4/</path>).
342     </p>
343    
344 swift 1.11 <p>
345     You only need the Packages CD if you want to perform a stage3 with GRP
346     installation.

382     <subsection>
383     <title>Downloading and Burning the LiveCDs</title>
384     <body>
385    
386     <p>
387     You have chosen to use a Gentoo LiveCD (if not, then you are reading the
388     wrong section). We'll first start by downloading and burning the chosen
389     LiveCD. We previously discussed the several available LiveCDs, but where can you
390     find them?
391     </p>
392    
393     <p>
394     Visit one of our <uri
395     link="/main/en/mirrors.xml">mirrors</uri> and go to
396 dertobi123 1.17 <path>releases/ppc/2004.2/livecd</path>, which is
397 swift 1.1 the path where the LiveCD(s) of your choice are located. Inside that
398     directory you'll find so-called ISO-files. Those are full CD images
399     which you can write on a CD-R.
400     </p>
401    
402     <p>
403     In case you wonder if your downloaded file is corrupted or not, you can
404     check its MD5 checksum and compare it with the MD5 checksum we provide (such as
405 dertobi123 1.17 <path>install-ppc-minimal-2004.2.iso.md5</path>). You can check the MD5 checksum
406 swift 1.1 with the <c>md5sum</c> tool under Linux/Unix or <uri
407 neysx 1.16 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
408 swift 1.1 </p>
409    
410     <p>
411 dertobi123 1.17 As long as Mac OS X does not support <c>md5sum</c> you have to use the md5
412     capability of <c>openssl</c>. Therefore type in Terminal.app:
413 swift 1.12 </p>
414    
415 dertobi123 1.18 <pre caption="md5sum with the help of openssl">
416 dertobi123 1.17 $ <i>openssl md5 /path/to/iso</i>
417     <comment>This could take some time depending of the size of the ISO and your CPU</comment>
418 swift 1.12 </pre>
419    
420     <p>
421 dertobi123 1.17 Now compare this output with the appropriate file found on the server where you
422     downloaded the ISO (the file will end with .md5). If it is the same, the ISO
423     image downloaded correctly. Be sure you have not mounted it (e.g. with Disk
424     Copy) yet!
425 swift 1.12 </p>
426    
427 dertobi123 1.17 <p>
428     More information are available in our <uri
429     link="/doc/en/gentoo-ppc-faq.xml">PPC FAQ.</uri>
430     </p>
431 swift 1.12
432     <p>
433 swift 1.1 To burn the downloaded ISO(s), you have to select raw-burning. How you
434 swift 1.14 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
435 dertobi123 1.17 <c>k3b</c> here; more information can be found in our <uri
436     link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri> and the <uri
437     link="/doc/en/gentoo-ppc-faq.xml">PPC FAQ</uri>.
438 swift 1.1 </p>
439    
440     <ul>
441     <li>
442     With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace
443     <path>/dev/hdc</path> with your CD-RW drive's device path) followed
444     by the path to the ISO file :)
445     </li>
446     <li>
447 dertobi123 1.17 With k3b, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
448 bennyc 1.6 you can locate your ISO file within the 'Image to Burn' area. Finally click
449 swift 1.3 <c>Start</c>.

463 dertobi123 1.17 On NewWorld machines place the LiveCD in the CD-ROM and reboot the system. When
464     the system-start-bell sounds, simply hold down the 'C' until the CD loads.
465     </p>
466    
467     <p>
468     If you have an OldWorld Mac the bootable portion of the livecd can't be used.
469     Instead you need to download <uri
470     link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working
471     MacOS installed on your system. You need to copy the <c>BootX Extension</c> from
472     the unpacked archive-file into the <c>Extensions Folder</c> and make a new
473     directory called <c>Linux Kernels</c> in the System Folder. In the next step you
474     need to copy the <c>G3</c> kernel and the <c>initrd.img.gz</c> from the LiveCD
475     into the <c>Linux Kernels</c> directory. Then reboot the system and wait for
476     BootX to load. After BootX loaded you still have to set up a few items. In the
477     options dialog you need to check <c>Use Secified RAM Disk</c> and select the
478     <c>initrd.img.gz</c> which you put in the <c>Linux Kernels</c> directory. The
479     ramdisk size should be set to at least <c>32000</c>. Furthermore the kernel
480     argument needs to be set to <c>rw init=/linuxrc cdroot</c>. Eventually you are
481     able to boot the LiveCD when you select Linux on Startup.
482     </p>
483    
484     <p>
485     After the LiveCD loaded, you will be greeted by a friendly welcome message and a
486     <e>boot:</e> prompt at the bottom of the screen.
487 swift 1.1 </p>
488    
489     <p>
490     At this prompt you are able to select a kernel for the subarchitecture you use.
491 dertobi123 1.17 We provide <c>G3</c>, <c>G4</c> and <c>G5</c>. All kernels are built with
492     support for multiple CPUs, but they will boot on single processor machines as
493     well.

609 dertobi123 1.17 When the LiveCD boots, it tries to detect all your hardware devices and
610 swift 1.1 loads the appropriate kernel modules to support your hardware. In the
611 dertobi123 1.17 vast majority of cases, it does a very good job. However, in some cases, it may
612     not auto-load the kernel modules you need. If the PCI auto-detection missed some
613     of your system's hardware, you will have to load the appropriate kernel modules
614     manually.

630     <body>
631    
632     <p>
633     If you are an advanced user, you might want to tweak the IDE hard disk
634     performance using <c>hdparm</c>. With the <c>-tT</c> options you can
635     test the performance of your disk (execute it several times to get a
636     more precise impression):
637     </p>
638    
639     <pre caption="Testing disk performance">
640     # <i>hdparm -tT /dev/hda</i>
641     </pre>
642    
643     <p>
644     To tweak, you can use any of the following examples (or experiment
645     yourself) which use <path>/dev/hda</path> as disk (substitute with your
646     disk):
647     </p>
648

657     <title>Optional: User Accounts</title>
658     <body>
659    
660     <p>
661     If you plan on giving other people access to your installation
662     environment or you want to chat using <c>irssi</c> without root privileges (for
663     security reasons), you need to create the necessary user accounts and change
664     the root password.
665     </p>
666    
667     <p>
668     To change the root password, use the <c>passwd</c> utility:
669     </p>
670    
671     <pre caption="Changing the root password">
672     # <i>passwd</i>
673     New password: <comment>(Enter your new password)</comment>
674     Re-enter password: <comment>(Re-enter your password)</comment>
675     </pre>
676    
677     <p>
678 swift 1.5 To create a user account, we first enter their credentials, followed by
679 swift 1.1 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
680     In the next example, we create a user called &quot;john&quot;.
681     </p>
682    
683     <pre caption="Creating a user account">
684     # <i>useradd john</i>
685     # <i>passwd john</i>
686     New password: <comment>(Enter john's password)</comment>
687     Re-enter password: <comment>(Re-enter john's password)</comment>
688     </pre>
689    
690     <p>
691     You can change your user id from root to the newly created user by using
692     <c>su</c>:
693     </p>
694    
695     <pre caption="Changing user id">

702     <title>Optional: Starting the SSH Daemon</title>
703     <body>
704    
705     <p>
706     If you want to allow other users to access your computer during the
707     Gentoo installation (perhaps because those users are going to help you
708     install Gentoo, or even do it for you), you need to create a user
709     account for them and perhaps even provide them with your root password
710     (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
711     </p>
712    
713     <p>
714     To fire up the SSH daemon, execute the following command:
715     </p>
716    
717     <pre caption="Starting the SSH daemon">
718     # <i>/etc/init.d/sshd start</i>
719     </pre>
720    
721     <p>
722     To be able to use sshd, you first need to setup your networking. Continue with
723     the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
