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.

28 <p>
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 1 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 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 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, zSeries, ...) and Amiga
47 systems. Be sure to read up on the <uri link="/doc/en/gentoo-ppc-faq.xml">Gentoo
48 PPC FAQ</uri> too 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.
82 </p>

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 <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>
278 <body>
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 LiveCD can be found in the <path>universal</path> subdirectory and is called
286 <c>install-ppc-minimal-2004.1.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 <c>install-ppc-universal-2004.1.iso</c> and can be found in the
329 <path>universal</path> subdirectory.
330 </p>
331
332 <p>
333 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 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 called <c>packages-g4-2004.1.iso</c> and can be found in the appropriate
341 subdirectory (<path>g4/</path>).
342 </p>
343
344 <p>
345 You only need the Packages CD if you want to perform a stage3 with GRP
346 installation.

381 <title>Download, Burn and Boot a Gentoo LiveCD</title>
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 <path>releases/ppc/2004.1/livecd/universal</path>, which is
397 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 <path>install-ppc-minimal-2004.1.iso.md5</path>). You can check the MD5 checksum
406 with the <c>md5sum</c> tool under Linux/Unix or <uri
407 link="http://www.md5summer.org">md5summer</uri> for Windows.
408 </p>
409
410 <p>
411 To burn the downloaded ISO(s), you have to select raw-burning. How you
412 do this is highly program-dependent. We will discuss a couple of popular
413 tools on how to do this.
414 </p>
415
416 <ul>
417 <li>
418 With EasyCD Creator you select <c>File</c>, <c>Record CD
419 from CD image</c>. Then you change the <c>Files of type</c> to <c>ISO image
420 file</c>. Then locate the ISO file and click <c>Open</c>. When you click on
421 <c>Start recording</c> the ISO image will be burned correctly onto the CD-R.
422 </li>
423 <li>
424 With Nero Burning ROM, select <c>File</c>, <c>Burn CD image</c>. Set the
425 type of file to <c>*.*</c> and select the ISO file. Older versions of Nero
426 will tell you they don't recognize the format -- confirm here, it does
427 recognize it but doesn't know it yet :) In the next dialog, set the
428 following parameters:
429 <ul>
430 <li>Type of image: <c>Data Mode 1</c></li>
431 <li>Block size: <c>2048 bytes</c></li>
432 <li>File precursor and length of the image trailer: <c>0 bytes</c></li>
433 <li>Scrambled: <c>no</c></li>
434 <li>Swapped: <c>no</c></li>
435 </ul>
436 Now click on <c>OK</c> and then <c>Burn</c> (the CD-R)
437 </li>
438 <li>
439 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace
440 <path>/dev/hdc</path> with your CD-RW drive's device path) followed
441 by the path to the ISO file :)
442 </li>
443 <li>
444 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
445 you can locate your ISO file within the 'Image to Burn' area. Finally click
446 <c>Start</c>.
447 </li>
448 <li>
449 With Mac OS X Panther, launch <c>Disk Utility</c> from
450 <path>Applications/Utilities</path>, select <c>Open</c> from the
451 <c>Images</c> menu, select the mounted disk image in the main window and
452 select <c>Burn</c> in the <c>Images</c> menu.
453 </li>
454 <li>
455 With Mac OS X Jaguar, launch <c>Disk Copy</c> from
456 <path>Applications/Utilities</path>, select <c>Burn Image</c> from the
457 <c>File</c> menu, select the ISO and click the <c>Burn</c> button.

471 Place the LiveCD in the CD-ROM and reboot the system. Hold down the 'C' key at
472 bootup (or run an OldWorld bootloader like BootX or quik). You will be greeted
473 by a friendly welcome message and a <e>boot:</e> prompt at the bottom of the
474 screen.
475 </p>
476
477 <p>
478 At this prompt you are able to select a kernel for the subarchitecture you use.
479 We provide <c>G3</c>, <c>G3-SMP</c>, <c>G4</c>, <c>G4-SMP</c>, <c>G5</c>,
480 <c>G5-SMP</c> and <c>G</c>. The various <c>-SMP</c> kernels are needed if your
481 system has multiple CPUs.
482 </p>
483
484 <p>
485 You are also able to tweak some kernel options at this prompt. The following
486 table lists the available boot options you can add:

499 <c>ofonly</c>. You can follow this tag with the resolution and refreshrate
500 you want to use. For instance <c>video=radeonfb:1280x1024@75</c>. If you are

595 When the Live CD boots, it tries to detect all your hardware devices and
596 loads the appropriate kernel modules to support your hardware. In the
597 vast majority of cases, it does a very good job. However, in some cases (the
598 SPARC LiveCDs don't even do autodetection), it may not auto-load the kernel
599 modules you need. If the PCI auto-detection missed some of your system's
600 hardware, you will have to load the appropriate kernel modules manually.
601 </p>
602
603 <p>
604 In the next example we try to load the <c>8139too</c> module (support for
605 certain kinds of network interfaces):

608 <pre caption="Loading kernel modules">

615 <title>Optional: Tweaking Hard Disk Performance</title>
616 <body>
617
618 <p>
619 If you are an advanced user, you might want to tweak the IDE hard disk
620 performance using <c>hdparm</c>. With the <c>-tT</c> options you can
621 test the performance of your disk (execute it several times to get a
622 more precise impression):
623 </p>
624
625 <pre caption="Testing disk performance">
626 # <i>hdparm -tT /dev/hda</i>
627 </pre>
628
629 <p>
630 To tweak, you can use any of the following examples (or experiment
631 yourself) which use <path>/dev/hda</path> as disk (substitute with your
632 disk):
633 </p>
634
635 <pre caption="Tweaking hard disk performance">
636 <comment>Activate DMA:</comment> # <i>hdparm -d 1 /dev/hda</i>
637 <comment>Activate DMA + Safe Performance-enhancing Options:</comment> # <i>hdparm -d 1 -A 1 -m 16 -u 1 -a 64 /dev/hda</i>

643 <title>Optional: User Accounts</title>
644 <body>
645
646 <p>
647 If you plan on giving other people access to your installation
648 environment or you want to chat using <c>irssi</c> without root privileges (for
649 security reasons), you need to create the necessary user accounts and change
650 the root password.
651 </p>
652
653 <p>
654 To change the root password, use the <c>passwd</c> utility:
655 </p>
656
657 <pre caption="Changing the root password">
658 # <i>passwd</i>
659 New password: <comment>(Enter your new password)</comment>
660 Re-enter password: <comment>(Re-enter your password)</comment>
661 </pre>
662
663 <p>
664 To create a user account, we first enter their credentials, followed by
665 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
666 In the next example, we create a user called &quot;john&quot;.
667 </p>
668
669 <pre caption="Creating a user account">
670 # <i>useradd john</i>
671 # <i>passwd john</i>
672 New password: <comment>(Enter john's password)</comment>
673 Re-enter password: <comment>(Re-enter john's password)</comment>
674 </pre>
675
676 <p>
677 You can change your user id from root to the newly created user by using
678 <c>su</c>:
679 </p>
680
681 <pre caption="Changing user id">
682 # <i>su john -</i>

688 <title>Optional: Starting the SSH Daemon</title>
689 <body>
690
691 <p>
692 If you want to allow other users to access your computer during the
693 Gentoo installation (perhaps because those users are going to help you
694 install Gentoo, or even do it for you), you need to create a user
695 account for them and perhaps even provide them with your root password
696 (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
697 </p>
698
699 <p>
700 To fire up the SSH daemon, execute the following command:
701 </p>
702
703 <pre caption="Starting the SSH daemon">
704 # <i>/etc/init.d/sshd start</i>
705 </pre>
706
707 <p>
708 To be able to use sshd, you first need to setup your networking. Continue with
709 the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
