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.

25 <title>The PPC64 Architecture</title>
26 <body>
27
28 <p>
29 Check the following requirements before you continue with the Gentoo
30 installation:
31 </p>
32
33 <ul>
34 <li>
35 You need at least 1 Gb of free disk space
36 </li>
37 <li>
38 You need at least 300 Mb of memory (RAM + swap)
39 </li>
40 <li>
41 For the <e>PowerPC64 architecture</e>, you can install Gentoo/PPC64 on
42 machines having a PowerPC64 microprocessor, including IBM RS/6000s,
43 Power Macintosh G5 systems, IBM pSeries (and soon IBM iSeries) boxen.
44 For a full list go to <uri>http://www.linuxppc64.org/hardware.shtml</uri>.

57 <p>
58 Still interested in trying out Gentoo? Well, then it is now time to
59 choose the installation medium you want to use. Yes, you have the
60 choice, no, they are not all equal, and yes, the result is always the same: a
61 Gentoo base system.
62 </p>
63
64 <p>
65 The installation media we will describe are:
66 </p>
67
68 <ul>
69 <li>Gentoo's Minimal LiveCD for Apple's G5</li>
70 <li>Gentoo's Minimal LiveCD for IBM pSeries RS/6000</li>
71 </ul>
72
73 <p>
74 As you can see there are no Universal CDs at the moment, but they will
75 follow. The consequence of this is that you have to download the stages
76 (see next paragraph) separately.

82 <title>The Three Stages</title>
83 <body>
84
85 <p>
86 Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
87 The one you choose depends on how much of the system you want to compile
88 yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
89 build the entire system from scratch. The <e>stage2</e> tarball is used for
90 building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
91 The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
92 been built for you. As we will explain later, you can also install
93 Gentoo without compiling anything (except your kernel and some optional
94 packages). If you want this, you have to use a <e>stage3</e> tarball.
95 </p>
96
97 <p>
98 Now what stage do you have to choose?
99 </p>
100
101 <p>
102 Starting from a <e>stage1</e> allows you to have total control over the
103 optimization settings and optional build-time functionality that is
104 initially enabled on your system. This makes <e>stage1</e> installs good for
105 power users who know what they are doing. It is also a great
106 installation method for those who would like to know more about the
107 inner workings of Gentoo Linux.
108 </p>
109
110 <p>
111 A <e>stage1</e> installation can only be performed when you have a working
112 Internet connection.

152
153 <p>
154 <e>Stage2</e> installs allow you to skip the bootstrap process and doing this
155 is fine if you are happy with the optimization settings that we chose
156 for your particular <e>stage2</e> tarball.
157 </p>
158
159 <p>
160 A <e>stage2</e> installation can only be performed when you have a working

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

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

242 Now take a look at the available installation media.

248 <title>Gentoo LiveCDs</title>
249 <body>
250
251 <p>
252 The <e>Gentoo LiveCDs</e> are bootable CDs which contain a
253 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
254 During the boot process your hardware is detected and the appropriate drivers
255 are loaded. They are maintained by Gentoo developers.
256 </p>
257
258 <p>
259 All LiveCDs allow you to boot, setup networking, initialize your
260 partitions and start installing Gentoo from the Internet. However, some
261 LiveCDs also contain all necessary source code so you are able to install
262 Gentoo without a working network configuration.
263 </p>
264
265 <p>
266 Now what do these LiveCDs contain?

275 <p>
276 This is a small, no-nonsense, bootable CD which sole purpose is to boot the
277 system, prepare the networking and continue with the Gentoo installation. It
278 does not contain any stages (or, in some cases, a single stage1 file),
279 source code or precompiled packages. For example the ppc variant of this
280 LiveCD can be found in the <path>universal</path> subdirectory and is called
281 <c>install-ppc-minimal-2004.1.iso</c>.

317 <title>Gentoo's Universal LiveCD (not available at the moment for
318 PPC64)</title>
319 <body>
320
321 <p>
322 Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
323 networking. It contains a stage1 and several stage3 tarballs (optimized for the
324 individual subarchitectures). For example the ppc variant of this CD is called
325 <c>install-ppc-universal-2004.1.iso</c> and can be found in the
326 <path>universal</path> subdirectory.
327 </p>
328
329 <p>
330 If you take a closer look on our mirrors, you will see
331 that we provide <e>Gentoo Package CDs</e>. This CD (which isn't
332 bootable) only contains precompiled packages and can be used to install software
333 after a succesfull Gentoo Installation. To install Gentoo, you only
334 need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
335 etc. without having to compile every single one of them, you need the Packages
336 CD too. For example the G4 (a subarchitecture of ppc) Packages CD is
337 called <c>packages-g4-2004.1.iso</c> and can be found in the appropriate
338 subdirectory (<path>g4/</path>).
339 </p>
340
341 <p>
342 You only need the Packages CD if you want to perform a stage3 with GRP
343 installation.

379 <title>Download, Burn and Boot a Gentoo LiveCD</title>
380 <subsection>
381 <title>Downloading and Burning the LiveCDs</title>
382 <body>
383
384 <p>
385 You have chosen to use a Gentoo LiveCD (if not, then you are reading the
386 wrong section). We'll first start by downloading and burning the chosen
387 LiveCD. We previously discussed the several available LiveCDs, but where can you
388 find them?
389 </p>
390
391 <p>
392 Visit one of our <uri
393 link="/main/en/mirrors.xml">mirrors</uri> and go to
394 <path>experimental/ppc64/livecd</path>, which is
395 the path where the LiveCD(s) of your choice are located. Inside that
396 directory you'll find so-called ISO-files. Those are full CD images
397 which you can write on a CD-R.
398 </p>
399
400 <p>
401 In case you wonder if your downloaded file is corrupted or not, you can check
402 its MD5 checksum and compare it with the MD5 checksum we provide (such as
403 <path>install-ppc64-minimal-2004.2.iso.md5</path>). You can check the MD5
404 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
405 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
406 </p>
407
408 <p>
409 As long as Mac OS X does not support <c>md5sum</c> you have to use the md5
410 capability of <c>openssl</c>.
411 </p>
412
413 <pre caption="md5sum with the help of openssl">
414 $ <i>openssl md5 /path/to/iso</i>
415 <comment>(This could take some time depending on the size of the ISO and your CPU)</comment>
416 </pre>
417
418 <p>
419 Now compare this output with the appropriate file found on the server where you
420 downloaded the ISO (the file will end with .md5). If it is the same, the ISO
421 image downloaded correctly. Be sure you have not mounted it (e.g. with Disk
422 Copy) yet!
423 </p>
424
425 <p>
426 More information is available in our <uri
427 link="/doc/en/gentoo-ppc-faq.xml">Gentoo/PPC FAQ</uri>.
428 </p>
429
430 <p>
431 To burn the downloaded ISO(s), you have to select raw-burning. How you
432 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
433 <c>k3b</c> here; more information canb be found in our <uri
434 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri> and the <uri
435 link="/doc/en/gentoo-ppc-faq.xml">Gentoo/PPC FAQ</uri>.
436 </p>
437
438 <ul>
439 <li>
440 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace
441 <path>/dev/hdc</path> with your CD-RW drive's device path) followed
442 by the path to the ISO file :)
443 </li>
444 <li>
445 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
446 you can locate your ISO file within the 'Image to Burn' area. Finally click
447 <c>Start</c>.

588 When the Live CD boots, it tries to detect all your hardware devices and
589 loads the appropriate kernel modules to support your hardware. In the
590 vast majority of cases, it does a very good job. However, in some cases (the
591 SPARC LiveCDs don't even do autodetection), it may not auto-load the kernel
592 modules you need. If the PCI auto-detection missed some of your system's
593 hardware, you will have to load the appropriate kernel modules manually.

613 performance using <c>hdparm</c>. With the <c>-tT</c> options you can
614 test the performance of your disk (execute it several times to get a
615 more precise impression):
616 </p>
617
618 <pre caption="Testing disk performance">
619 # <i>hdparm -tT /dev/hda</i>
620 </pre>
621
622 <p>
623 To tweak, you can use any of the following examples (or experiment
624 yourself) which use <path>/dev/hda</path> as disk (substitute with your
625 disk):
626 </p>
627
628 <pre caption="Tweaking hard disk performance">
629 <comment>Activate DMA:</comment> # <i>hdparm -d 1 /dev/hda</i>
630 <comment>Activate DMA + Safe Performance-enhancing Options:</comment> # <i>hdparm -d 1 -A 1 -m 16 -u 1 -a 64 /dev/hda</i>

639 <p>
640 If you plan on giving other people access to your installation
641 environment or you want to chat using <c>irssi</c> without root privileges (for
642 security reasons), you need to create the necessary user accounts and change
643 the root password.
644 </p>
645
646 <p>
647 To change the root password, use the <c>passwd</c> utility:
648 </p>
649
650 <pre caption="Changing the root password">
651 # <i>passwd</i>
652 New password: <comment>(Enter your new password)</comment>
653 Re-enter password: <comment>(Re-enter your password)</comment>
654 </pre>
655
656 <p>
657 To create a user account, we first enter their credentials, followed by
658 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
659 In the next example, we create a user called &quot;john&quot;.
660 </p>
661
662 <pre caption="Creating a user account">
663 # <i>useradd john</i>
664 # <i>passwd john</i>
665 New password: <comment>(Enter john's password)</comment>
666 Re-enter password: <comment>(Re-enter john's password)</comment>
667 </pre>
668
669 <p>
670 You can change your user id from root to the newly created user by using
671 <c>su</c>:
672 </p>
673
674 <pre caption="Changing user id">
675 # <i>su john -</i>

682 <body>
683
684 <p>
685 If you want to view the Gentoo Handbook (either from-CD or online) during the
686 installation, make sure you have created a user account (see <uri
687 link="#useraccouts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
688 go to a new terminal and log in.
689 </p>
690
691 <p>
692 If you want to view the documentation on the CD you can immediately run
693 <c>links2</c> to read it:
694 </p>
695
696 <pre caption="Viewing the on-CD documentation">
697 # <i>links2 /mnt/cdrom/docs/html/index.html</i>
698 </pre>
699
700 <p>
701 However, it is preferred that you use the online Gentoo Handbook as it will be
702 more recent than the one provided on the CD. You can view it using <c>links2</c>
703 as well, but only after having completed the <e>Configuring your Network</e>
704 chapter (otherwise you won't be able to go on the Internet to view the
705 document):
706 </p>
707
708 <pre caption="Viewing the Online Documentation">
709 # <i>links2 http://www.gentoo.org/doc/en/handbook/handbook-ppc64.xml</i>
710 </pre>
711
712 <p>
713 You can go back to your original terminal by pressing <c>Alt-F1</c>.

719 <title>Optional: Starting the SSH Daemon</title>
720 <body>
721
722 <p>
723 If you want to allow other users to access your computer during the
724 Gentoo installation (perhaps because those users are going to help you
725 install Gentoo, or even do it for you), you need to create a user
726 account for them and perhaps even provide them with your root password
727 (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
728 </p>
729
730 <p>
731 To fire up the SSH daemon, execute the following command:
732 </p>
733
734 <pre caption="Starting the SSH daemon">
735 # <i>/etc/init.d/sshd start</i>
736 </pre>
737
738 <p>
739 To be able to use sshd, you first need to setup your networking. Continue with
740 the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
