16 <p>
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.

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

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 <p>
116 A <e>stage1</e> installation can only be performed when you have a working
117 Internet connection.
118 </p>

156 </table>
157
158 <p>
159 <e>Stage2</e> installs allow you to skip the bootstrap process and doing this
160 is fine if you are happy with the optimization settings that we chose
161 for your particular <e>stage2</e> tarball.
162 </p>
163
164 <p>
165 A <e>stage2</e> installation can only be performed when you have a working
166 Internet connection.

205
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 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
246 <p>
247 Now take a look at the available installation media.

253 <title>Gentoo LiveCDs</title>
254 <body>
255
256 <note>
257 The Gentoo/PPC 2004.2 release is not official, so you will not find them on the
258 mirrors. Nevertheless we compiled LiveCDs and made them available at <uri
259 link="http://www.metadistribution.org/gentoo/2004.2/"/>, <uri
260 link="ftp://ftp2.stw-bonn.de/pub/mirror/gentoo/releases/ppc/2004.2/livecd/"/> and
261 via <uri link="http://torrents.gentoo.org/torrents/">BitTorrent</uri>.
262 </note>
263
264 <note>
265 It is known that the Pegasos II will not boot the 2004.2 LiveCD. Please use the
266 2004.1 LiveCD.
267 </note>
268
269 <p>
270 The <e>Gentoo LiveCDs</e> are bootable CDs which contain a
271 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
272 During the boot process your hardware is detected and the appropriate drivers
273 are loaded. They are maintained by Gentoo developers.
274 </p>
275
276 <p>
277 All LiveCDs allow you to boot, setup networking, initialize your
278 partitions and start installing Gentoo from the Internet. However, some
279 LiveCDs also contain all necessary source code so you are able to install
280 Gentoo without a working network configuration.
281 </p>
282
283 <p>
284 Now what do these LiveCDs contain?

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

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

394 <title>Download, Burn and Boot a Gentoo LiveCD</title>
395 <subsection>
396 <title>Downloading and Burning the LiveCDs</title>
397 <body>
398
399 <p>
400 You have chosen to use a Gentoo LiveCD (if not, then you are reading the
401 wrong section). We'll first start by downloading and burning the chosen
402 LiveCD. We previously discussed the several available LiveCDs, but where can you
403 find them?
404 </p>
405
406 <p>
407 Visit one of our <uri
408 link="/main/en/mirrors.xml">mirrors</uri> and go to
409 <path>releases/ppc/2004.2/livecd</path>, which is
410 the path where the LiveCD(s) of your choice are located. Inside that
411 directory you'll find so-called ISO-files. Those are full CD images
412 which you can write on a CD-R.
413 </p>
414
415 <p>
416 In case you wonder if your downloaded file is corrupted or not, you can
417 check its MD5 checksum and compare it with the MD5 checksum we provide (such as
418 <path>install-ppc-minimal-2004.2.iso.md5</path>). You can check the MD5 checksum
419 with the <c>md5sum</c> tool under Linux/Unix or <uri
420 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
421 </p>
422
423 <p>
424 As long as Mac OS X does not support <c>md5sum</c> you have to use the md5
425 capability of <c>openssl</c>. Therefore type in Terminal.app:
426 </p>
427
428 <pre caption="md5sum with the help of openssl">
429 $ <i>openssl md5 /path/to/iso</i>
430 <comment>This could take some time depending of the size of the ISO and your CPU</comment>
431 </pre>
432
433 <p>
434 Now compare this output with the appropriate file found on the server where you
435 downloaded the ISO (the file will end with .md5). If it is the same, the ISO
436 image downloaded correctly. Be sure you have not mounted it (e.g. with Disk
437 Copy) yet!
438 </p>
439
440 <p>
441 More information are available in our <uri
442 link="/doc/en/gentoo-ppc-faq.xml">PPC FAQ.</uri>
443 </p>
444
445 <p>
446 To burn the downloaded ISO(s), you have to select raw-burning. How you
447 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
448 <c>k3b</c> here; more information can be found in our <uri
449 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri> and the <uri
450 link="/doc/en/gentoo-ppc-faq.xml">PPC FAQ</uri>.
451 </p>
452
453 <ul>
454 <li>
455 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace
456 <path>/dev/hdc</path> with your CD-RW drive's device path) followed
457 by the path to the ISO file :)
458 </li>
459 <li>
460 With k3b, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
461 you can locate your ISO file within the 'Image to Burn' area. Finally click
462 <c>Start</c>.

470 <title>Booting the PPC LiveCD(s)</title>
471 <subsection>
472 <title>Default: Apple/IBM</title>
473 <body>
474
475 <p>
476 On NewWorld machines place the LiveCD in the CD-ROM and reboot the system. When
477 the system-start-bell sounds, simply hold down the 'C' until the CD loads.
478 </p>
479
480 <p>
481 If you have an OldWorld Mac the bootable portion of the livecd can't be used.
482 Instead you need to download <uri
483 link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working
484 MacOS installed on your system. You need to copy the <c>BootX Extension</c> from
485 the unpacked archive-file into the <c>Extensions Folder</c> and make a new
486 directory called <c>Linux Kernels</c> in the System Folder. In the next step you
487 need to copy the <c>G3</c> kernel and the <c>initrd.img.gz</c> from the LiveCD
488 into the <c>Linux Kernels</c> directory. Then reboot the system and wait for
489 BootX to load. After BootX loaded you still have to set up a few items. In the
490 options dialog you need to check <c>Use Specified RAM Disk</c> and select the
491 <c>initrd.img.gz</c> which you put in the <c>Linux Kernels</c> directory. The
492 ramdisk size should be set to at least <c>32000</c>. Furthermore the kernel
493 argument needs to be set to <c>rw init=/linuxrc cdroot</c>. Eventually you are
494 able to boot the LiveCD when you select Linux on Startup.
495 </p>
496
497 <p>
498 After the LiveCD loaded, you will be greeted by a friendly welcome message and a
499 <e>boot:</e> prompt at the bottom of the screen.
500 </p>
501
502 <p>
503 At this prompt you are able to select a kernel for the subarchitecture you use.
504 We provide <c>G3</c>, <c>G4</c> and <c>G5</c>. All kernels are built with
505 support for multiple CPUs, but they will boot on single processor machines as
506 well.
507 </p>
508
509 <p>
510 You are also able to tweak some kernel options at this prompt. The following
511 table lists the available boot options you can add:

523 <c>radeonfb</c>, <c>rivafb</c>, <c>atyfb</c>, <c>aty128</c> or
524 <c>ofonly</c>. You can follow this tag with the resolution and refreshrate
525 you want to use. For instance <c>video=radeonfb:1280x1024@75</c>. If you are
526 uncertain what to choose, <c>ofonly</c> will most certainly work.

585 switch to other consoles by pressing Alt-fn-F2, Alt-fn-F3 and Alt-fn-F4. Get
586 back to the one you started on by pressing Alt-fn-F1.

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

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

631 In the next example we try to load the <c>8139too</c> module (support for
632 certain kinds of network interfaces):

642 <title>Optional: Tweaking Hard Disk Performance</title>
643 <body>
644
645 <p>
646 If you are an advanced user, you might want to tweak the IDE hard disk
647 performance using <c>hdparm</c>. With the <c>-tT</c> options you can
648 test the performance of your disk (execute it several times to get a
649 more precise impression):
650 </p>
651
652 <pre caption="Testing disk performance">
653 # <i>hdparm -tT /dev/hda</i>
654 </pre>
655
656 <p>
657 To tweak, you can use any of the following examples (or experiment
658 yourself) which use <path>/dev/hda</path> as disk (substitute with your
659 disk):
660 </p>
661
662 <pre caption="Tweaking hard disk performance">
663 <comment>Activate DMA:</comment> # <i>hdparm -d 1 /dev/hda</i>

672
673 <p>
674 If you plan on giving other people access to your installation
675 environment or you want to chat using <c>irssi</c> without root privileges (for
676 security reasons), you need to create the necessary user accounts and change
677 the root password.
678 </p>
679
680 <p>
681 To change the root password, use the <c>passwd</c> utility:
682 </p>
683
684 <pre caption="Changing the root password">
685 # <i>passwd</i>
686 New password: <comment>(Enter your new password)</comment>
687 Re-enter password: <comment>(Re-enter your password)</comment>
688 </pre>
689
690 <p>
691 To create a user account, we first enter their credentials, followed by
692 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
693 In the next example, we create a user called &quot;john&quot;.
694 </p>
695
696 <pre caption="Creating a user account">
697 # <i>useradd john</i>
698 # <i>passwd john</i>
699 New password: <comment>(Enter john's password)</comment>
700 Re-enter password: <comment>(Re-enter john's password)</comment>
701 </pre>
702
703 <p>
704 You can change your user id from root to the newly created user by using
705 <c>su</c>:

716 <body>
717
718 <p>
719 If you want to view the Gentoo Handbook (either from-CD or online) during the
720 installation, make sure you have created a user account (see <uri
721 link="#useraccouts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
722 go to a new terminal and log in.
723 </p>
724
725 <p>
726 If you want to view the documentation on the CD you can immediately run
727 <c>links2</c> to read it:
728 </p>
729
730 <pre caption="Viewing the on-CD documentation">
731 # <i>links2 /mnt/cdrom/docs/html/index.html</i>
732 </pre>
733
734 <p>
735 However, it is preferred that you use the online Gentoo Handbook as it will be
736 more recent than the one provided on the CD. You can view it using <c>links2</c>
737 as well, but only after having completed the <e>Configuring your Network</e>
738 chapter (otherwise you won't be able to go on the Internet to view the
739 document):
740 </p>
741
742 <pre caption="Viewing the Online Documentation">
743 # <i>links2 http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml</i>
744 </pre>
745

753 <title>Optional: Starting the SSH Daemon</title>
754 <body>
755
756 <p>
757 If you want to allow other users to access your computer during the
758 Gentoo installation (perhaps because those users are going to help you
759 install Gentoo, or even do it for you), you need to create a user
760 account for them and perhaps even provide them with your root password
761 (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
762 </p>
763
764 <p>
765 To fire up the SSH daemon, execute the following command:
766 </p>
767
768 <pre caption="Starting the SSH daemon">
769 # <i>/etc/init.d/sshd start</i>
770 </pre>
771
772 <p>
773 To be able to use sshd, you first need to setup your networking. Continue with
774 the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
