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

32 <p>
33 Check the following requirements before you
34 continue with the Gentoo installation:
35 </p>
36
37 <ul>
38 <li>
39 You need at least 2 GB of free disk space
40 </li>
41 <li>
42 If you do not use prebuilt packages, you need at least 300 MB of memory (RAM +
43 swap), if you do use prebuilt packages you need at least 64 MB of memory to boot the system.
44 </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.

66 Still interested in trying out Gentoo? Well, then it is now time to
67 choose the installation medium you want to use. Yes, you have the
68 choice, no, they are not all equal, and yes, the result is always the same: a
69 Gentoo base system.
70 </p>
71
72 <p>
73 The installation media we will describe are:
74 </p>
75
76 <ul>
77 <li>Gentoo's Minimal LiveCD</li>
78 <li>Gentoo's Universal LiveCD</li>
79 </ul>
80
81 <p>
82 Every single media has its advantages and disadvantages. We will list
83 the pros and cons of every medium so you have all the information to
84 make a justified decision. But before we continue, let's explain our
85 three-stage installation.

91 <title>The Three Stages</title>
92 <body>
93
94 <p>
95 Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
96 The one you choose depends on how much of the system you want to compile
97 yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
98 build the entire system from scratch. The <e>stage2</e> tarball is used for
99 building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
100 The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
101 been built for you. As we will explain later, you can also install
102 Gentoo without compiling anything (except your kernel and some optional
103 packages). If you want this, you have to use a <e>stage3</e> tarball.
104 </p>
105
106 <p>
107 Now what stage do you have to choose?
108 </p>
109
110 <p>
111 Starting from a <e>stage1</e> allows you to have total control over the
112 optimization settings and optional build-time functionality that is
113 initially enabled on your system. This makes <e>stage1</e> installs good for
114 power users who know what they are doing. It is also a great
115 installation method for those who would like to know more about the
116 inner workings of Gentoo Linux.
117 </p>
118
119 <p>
120 A <e>stage1</e> installation can only be performed when you have a working
121 Internet connection.
122 </p>

160 </table>
161
162 <p>
163 <e>Stage2</e> installs allow you to skip the bootstrap process and doing this
164 is fine if you are happy with the optimization settings that we chose
165 for your particular <e>stage2</e> tarball.
166 </p>
167
168 <p>
169 A <e>stage2</e> installation can only be performed when you have a working
170 Internet connection.

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

243 Write down (or remember) what stage you want to use. You need this later when
244 you decide what LiveCD (or other installation medium) you want to use. You might
245 be interested to know that, if you decide to use different optimization settings
246 after having installed Gentoo, you will be able to recompile your entire system
247 with the new optimization settings.
248 </p>
249
250 <p>
251 Now take a look at the available installation media.

257 <title>Gentoo LiveCDs</title>
258 <body>
259
260 <note>
261 The Gentoo/PPC 2004.2 release is not official, so you will not find them on the
262 mirrors. All of our self-organised mirrors are currently down. The only chance
263 you can get the LiveCDs is via <uri
264 link="http://torrents.gentoo.org/torrents/">BitTorrent</uri>.
265 </note>
266
267 <note>
268 It is known that the Pegasos II will not boot the 2004.2 LiveCD. Please use the
269 2004.1 LiveCD.
270 </note>
271
272 <p>
273 The <e>Gentoo LiveCDs</e> are bootable CDs which contain a
274 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
275 During the boot process your hardware is detected and the appropriate drivers
276 are loaded. They are maintained by Gentoo developers.
277 </p>
278
279 <p>
280 All LiveCDs allow you to boot, set up networking, initialize your
281 partitions and start installing Gentoo from the Internet. However, some
282 LiveCDs also contain all necessary source code so you are able to install
283 Gentoo without a working network configuration.
284 </p>
285
286 <p>
287 Now what do these LiveCDs contain?

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

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

337 <title>Gentoo's Universal LiveCD</title>
338 <body>
339
340 <p>
341 Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
342 networking. It contains a stage1 and several stage3 tarballs (optimized for the
343 individual 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>
349 If you take a closer look on our mirrors, you will see
350 that we provide <e>Gentoo Package CDs</e>. This CD (which isn't
351 bootable) only contains precompiled packages and can be used to install software
352 after a succesfull Gentoo Installation. To install Gentoo, you only
353 need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
354 etc. without having to compile every single one of them, you need the Packages
355 CD too. For example the G4 (a subarchitecture of ppc) Packages CD is
356 called <c>packages-g4-2004.2.iso</c> and can be found in the appropriate
357 subdirectory (<path>g4/</path>).
358 </p>
359
360 <p>
361 You only need the Packages CD if you want to perform a stage3 with GRP
362 installation.

398 <subsection>
399 <title>Downloading and Burning the LiveCDs</title>
400 <body>
401
402 <p>
403 You have chosen to use a Gentoo LiveCD (if not, then you are reading the
404 wrong section). We'll first start by downloading and burning the chosen
405 LiveCD. We previously discussed the several available LiveCDs, but where can you
406 find them?
407 </p>
408
409 <p>
410 Visit one of our <uri
411 link="/main/en/mirrors.xml">mirrors</uri> and go to
412 <path>releases/ppc/2004.2/livecd</path>, which is
413 the path where the LiveCD(s) of your choice are located. Inside that
414 directory you'll find so-called ISO-files. Those are full CD images
415 which you can write on a CD-R.
416 </p>
417
418 <p>
419 In case you wonder if your downloaded file is corrupted or not, you can
420 check 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
422 with the <c>md5sum</c> tool under Linux/Unix or <uri
423 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
424 </p>
425
426 <p>
427 As long as Mac OS X does not support <c>md5sum</c> you have to use the md5
428 capability 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>
437 Now compare this output with the appropriate file found on the server where you
438 downloaded the ISO (the file will end with .md5). If it is the same, the ISO
439 image downloaded correctly. Be sure you have not mounted it (e.g. with Disk
440 Copy) yet!
441 </p>
442
443 <p>
444 More information are available in our <uri
445 link="/doc/en/gentoo-ppc-faq.xml">PPC FAQ.</uri>
446 </p>
447
448 <p>
449 To burn the downloaded ISO(s), you have to select raw-burning. How you
450 do this is highly program-dependent. We will discuss <c>cdrecord</c>,
451 <c>k3b</c> and the MacOS burning possibilities here; more information can
452 be found in our <uri link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri> and
453 the <uri link="/doc/en/gentoo-ppc-faq.xml">PPC FAQ</uri>.
454 </p>
455
456 <ul>
457 <li>
458 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace
459 <path>/dev/hdc</path> with your CD-RW drive's device path) followed
460 by the path to the ISO file :)
461 </li>
462 <li>
463 With k3b, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
464 you can locate your ISO file within the 'Image to Burn' area. Finally click
465 <c>Start</c>.
466 </li>
467 <li>
468 With Mac OS X Panther, launch <c>Disk Utility</c> from
469 <path>Applications/Utilities</path>, select <c>Open</c> from the
470 <c>Images</c> menu, select the mounted disk image in the main window and
471 select <c>Burn</c> in the <c>Images</c> menu.
472 </li>
473 <li>
474 With Mac OS X Jaguar, launch <c>Disk Copy</c> from
475 <path>Applications/Utilities</path>, select <c>Burn Image</c> from the
476 <c>File</c> menu, select the ISO and click the <c>Burn</c> button.

487 <body>
488
489 <p>
490 On NewWorld machines place the LiveCD in the CD-ROM and reboot the system. When
491 the system-start-bell sounds, simply hold down the 'C' until the CD loads.
492 </p>
493
494 <p>
495 If you have an OldWorld Mac the bootable portion of the livecd can't be used.
496 Instead you need to download <uri
497 link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working
498 MacOS installed on your system. You need to copy the <c>BootX Extension</c> from
499 the unpacked archive-file into the <c>Extensions Folder</c> and make a new
500 directory called <c>Linux Kernels</c> in the System Folder. In the next step you
501 need to copy the <c>G3</c> kernel and the <c>initrd.img.gz</c> from the LiveCD
502 into the <c>Linux Kernels</c> directory. Then reboot the system and wait for
503 BootX to load. After BootX loaded you still have to set up a few items. In the
504 options 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
506 ramdisk size should be set to at least <c>32000</c>. Furthermore the kernel
507 argument needs to be set to <c>rw init=/linuxrc cdroot</c>. Eventually you are
508 able to boot the LiveCD when you select Linux on Startup.
509 </p>
510
511 <p>
512 After the LiveCD loaded, you will be greeted by a friendly welcome message and a
513 <e>boot:</e> prompt at the bottom of the screen.
514 </p>
515
516 <p>
517 At this prompt you are able to select a kernel for the subarchitecture you use.
518 We provide <c>G3</c>, <c>G4</c> and <c>G5</c>. All kernels are built with
519 support for multiple CPUs, but they will boot on single processor machines as
520 well.
521 </p>
522
523 <p>
524 You are also able to tweak some kernel options at this prompt. The following
525 table lists the available boot options you can add:

539 you want to use. For instance <c>video=radeonfb:1280x1024@75</c>. If you are

598 You will be greeted by a root ("#") prompt on the current console. You can also
599 switch to other consoles by pressing Alt-fn-F2, Alt-fn-F3 and Alt-fn-F4. Get

604 If you are installing Gentoo on a system with a non-US keyboard, use
605 <c>loadkeys</c> to load the keymap for your keyboard. To list the available
606 keymaps, execute <c>ls /usr/share/keymaps/i386</c>. Do not use the keymaps in
607 <path>ppc</path> or <path>mac</path> as they are for ADB-based OldWorld
608 machines.

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

645 In the next example we try to load the <c>8139too</c> module (support for

656 <title>Optional: Tweaking Hard Disk Performance</title>
657 <body>
658
659 <p>
660 If you are an advanced user, you might want to tweak the IDE hard disk
661 performance using <c>hdparm</c>. With the <c>-tT</c> options you can
662 test the performance of your disk (execute it several times to get a
663 more precise impression):
664 </p>
665
666 <pre caption="Testing disk performance">
667 # <i>hdparm -tT /dev/hda</i>
668 </pre>
669
670 <p>
671 To tweak, you can use any of the following examples (or experiment
672 yourself) which use <path>/dev/hda</path> as disk (substitute with your
673 disk):
674 </p>
675
676 <pre caption="Tweaking hard disk performance">

687 <p>
688 If you plan on giving other people access to your installation
689 environment or you want to chat using <c>irssi</c> without root privileges (for
690 security reasons), you need to create the necessary user accounts and change
691 the root password.
692 </p>
693
694 <p>
695 To change the root password, use the <c>passwd</c> utility:
696 </p>
697
698 <pre caption="Changing the root password">
699 # <i>passwd</i>
700 New password: <comment>(Enter your new password)</comment>
701 Re-enter password: <comment>(Re-enter your password)</comment>
702 </pre>
703
704 <p>
705 To create a user account, we first enter their credentials, followed by
706 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
707 In the next example, we create a user called &quot;john&quot;.
708 </p>
709
710 <pre caption="Creating a user account">
711 # <i>useradd -m -G users john</i>
712 # <i>passwd john</i>

718 You can change your user id from root to the newly created user by using
719 <c>su</c>:

730 <body>
731
732 <p>
733 If you want to view the Gentoo Handbook (either from-CD or online) during the
734 installation, make sure you have created a user account (see <uri
735 link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
736 go to a new terminal and log in.
737 </p>
738
739 <p>
740 If you want to view the documentation on the CD you can immediately run
741 <c>links2</c> to read it:
742 </p>
743
744 <pre caption="Viewing the on-CD documentation">
745 # <i>links2 /mnt/cdrom/docs/html/index.html</i>
746 </pre>
747
748 <p>
749 However, it is preferred that you use the online Gentoo Handbook as it will be
750 more recent than the one provided on the CD. You can view it using <c>links2</c>
751 as well, but only after having completed the <e>Configuring your Network</e>
752 chapter (otherwise you won't be able to go on the Internet to view the
753 document):
754 </p>
755
756 <pre caption="Viewing the Online Documentation">
757 # <i>links2 http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml</i>

767 <title>Optional: Starting the SSH Daemon</title>
768 <body>
769
770 <p>
771 If you want to allow other users to access your computer during the
772 Gentoo installation (perhaps because those users are going to help you
773 install Gentoo, or even do it for you), you need to create a user
774 account for them and perhaps even provide them with your root password
775 (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
776 </p>
777
778 <p>
779 To fire up the SSH daemon, execute the following command:
780 </p>
781
782 <pre caption="Starting the SSH daemon">
783 # <i>/etc/init.d/sshd start</i>
784 </pre>
785
786 <p>
787 To be able to use sshd, you first need to set up your networking. Continue with
788 the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
