84 <title>The Gentoo Installation Approaches</title>
85 <subsection>
86 <title>Introduction</title>
87 <body>
88
89 <p>
90 Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
91 A stage file is a tarball (compressed archive) that contains a minimal
92 environment.
93 </p>
94
95 <ul>
96 <li>
97 A stage1 file contains nothing more than a compiler, Portage (Gentoo's
98 software management system) and a couple of packages on which the compiler
99 or Portage depends.
100 </li>
101 <li>
102 A stage2 file contains a so-called bootstrapped system, a minimal
103 environment from which one can start building all other necessary
104 applications that make a Gentoo environment complete.
105 </li>
106 <li>
107 A stage3 file contains a prebuilt minimal system which is almost fully
108 deployable. It only lacks a few applications where you, the Gentoo user,
109 needs to choose which one you want to install.
110 </li>
111 </ul>
112
113 <p>
114 To help you decide what stage file you want to use, we have written down the
115 major advantages and disadvantages of each stage file.
116 </p>

119 </subsection>
120 <subsection>
121 <title>A Stage1 Approach</title>
122 <body>
123
124 <p>
125 A <e>stage1</e> is used when you want to bootstrap and build the entire system
126 from scratch.
127 </p>
128
129 <p>
130 Starting from a stage1 allows you to have total control over the
131 optimization settings and optional build-time functionality that is
132 initially enabled on your system. This makes <e>stage1</e> installs good for
133 power users who know what they are doing. It is also a great
134 installation method for those who would like to know more about the
135 inner workings of Gentoo Linux.

181
182 <p>
183 A <e>stage2</e> is used for building the entire system from a bootstrapped
184 "semi-compiled" state.
185 </p>
186
187 <p>
188 Stage2 installs allow you to skip the bootstrap process; doing this
189 is fine if you are happy with the optimization settings that we chose
190 for your particular stage2 tarball.

233 <title>A Stage3 Approach</title>
234 <body>
235
236 <p>
237 A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
238 built for you. You will only need to build a few packages of which we can't
239 decide for you which one to choose.
240 </p>
241
242 <p>
243 Choosing to go with a stage3 allows for the fastest install of Gentoo
244 Linux, but also means that your base system will have the optimization
245 settings that we chose for you (which to be honest, are good settings
246 and were carefully chosen to enhance performance while maintaining
247 stability). Stage3 is also required if you want to install Gentoo using
248 prebuilt packages or without a network connection.
249 </p>

261 <th>-</th>
262 <ti>You cannot tweak the base system - it's built already</ti>
263 </tr>
264 </table>
265
266 <p>
267 You might be interested to know that, if you decide to use different
268 optimization settings after having installed Gentoo, you will be able to
269 recompile your entire system with the new optimization settings.

276 <title>The Gentoo Installation CDs</title>
277 <subsection>
278 <title>Introduction</title>
279 <body>
280
281 <p>
282 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
283 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
284 During the boot process your hardware is detected and the appropriate drivers
285 are loaded. They are maintained by Gentoo developers.
286 </p>
287
288 <p>
289 All Installation CDs allow you to boot, set up networking, initialize your
290 partitions and start installing Gentoo from the Internet. We currently provide
291 two Installation CDs which are equaly suitable to install Gentoo from, as long
292 as you're planning on performing an Internet-based installation using the
293 latest version of the available packages.
294 </p>
295
296 <p>
297 If you wish to install Gentoo without a working Internet connection, please use
298 the installation instructions described in the <uri
299 link="2005.1/index.xml">Gentoo 2005.1 Handbooks</uri>.
300 </p>
301
302 <p>
303 The two Installation CDs that we currently provide are:
304 </p>
305
306 <ul>
307 <li>
308 The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable
309 CD which sole purpose is to boot the system, prepare the networking and
310 continue with the Gentoo installation.
311 </li>
312 <li>
313 The Gentoo <e>Universal</e> Installation CD, a bootable CD with the same
314 abilities as the Minimal Installation CD. Additionally, it contains a
315 stage1 and several stage3 tarballs (optimized for the individual
316 subarchitectures).
317 </li>
318 </ul>
319
320 <p>
321 To help you decide which Installation CD you need, we have written down the
322 major advantages and disadvantages of each Installation CD.

331 <p>
332 The Minimal Installation CD is called <c>install-ppc-minimal-2005.1.iso</c> and
333 takes up only 52 MB of diskspace. You can use this Installation CD to install
334 Gentoo, but always with a working Internet connection only.

370 and consumes the entire surface of a 650 MB CD. You can use this Installation
371 CD to install Gentoo, and you can even use it to install Gentoo without a
372 working internet connection, just in case you want to bring Gentoo to another
373 PC than the one you are currently installing Gentoo on :)

401 You might find a so-called <e>Package CD</e> on one of our mirrors. This CD is
402 no Installation CD but an additional resource that can be exploited during a
403 networkless installation. It contains prebuilt packages (the so-called GRP
404 set) that allows you to easily and quickly install additional applications
405 (such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless
406 Gentoo installation.

414 <title>Download, Burn and Boot a Gentoo Installation CD</title>
415 <subsection>
416 <title>Downloading and Burning the Installation CDs</title>
417 <body>
418
419 <p>
420 You have chosen to use a Gentoo Installation CD. We'll first start by
421 downloading and burning the chosen Installation CD. We previously discussed
422 the several available Installation CDs, but where can you find them?
423 </p>
424
425 <p>
426 You can download any of the Installation CDs (and, if you want to, a Packages
427 CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
428 Installation CDs are located in the <path>releases/ppc/2005.1/installcd</path>
429 directory.
430 </p>
431
432 <p>
433 Inside that directory you'll find so-called ISO-files. Those are full CD images
434 which you can write on a CD-R.
435 </p>
436
437 <p>
438 In case you wonder if your downloaded file is corrupted or not, you can
439 check its MD5 checksum and compare it with the MD5 checksum we provide (such as
440 <path>install-ppc-minimal-2005.1.iso.md5</path>). You can check the MD5 checksum
441 with the <c>md5sum</c> tool under Linux/Unix or
442 <uri link="http://www.etree.org/md5com.html">md5sum</uri> for Windows. If
443 <c>md5sum</c> is not available on Mac OS X, see the
444 <uri link="/doc/en/gentoo-ppc-faq.xml#doc_chap1">Gentoo PPC FAQ</uri> for help.
445 </p>
446
447 <p>
448 Another way to check the validity of the downloaded file is to use GnuPG to
449 verify the cryptographic signature that we provide (the file ending with
450 <path>.asc</path>). Download the signature file and obtain the public key:
451 </p>
452
453 <pre caption="Obtaining the public key">
454 $ <i>gpg --keyserver pgp.mit.edu --recv-keys 17072058</i>
455 </pre>
456
457 <p>
458 Now verify the signature:
459 </p>
460
461 <pre caption="Verify the cryptographic signature">
462 $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
463 </pre>
464
465 <p>
466 To burn the downloaded ISO(s), you have to select raw-burning. How you
467 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
468 <c>K3B</c> here; more information can be found in our <uri
469 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
470 </p>
471
472 <ul>
473 <li>
474 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
475 file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's
476 device path).
477 </li>
478 <li>
479 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
480 you can locate your ISO file within the 'Image to Burn' area. Finally click
481 <c>Start</c>.

488 <title>Default: Booting the Installation CD with Yaboot</title>
489 <body>
490
491 <p>
492 On NewWorld machines place the Installation CD in the CD-ROM and reboot the
493 system. When the system-start-bell sounds, simply hold down the 'C' until the
494 CD loads.
495 </p>
496
497 <p>
498 After the Installation CD loaded, you will be greeted by a friendly welcome
499 message and a <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 some of the available boot options you can add:

522 This option takes one of the following vendor-specific tags:
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.

559 <title>Alternative: Booting the Installation CD on a Pegasos</title>
560 <body>
561
562 <p>
563 On the Pegasos simply insert the CD and at the SmartFirmware boot-prompt type
564 <c>boot cd /boot/menu</c>. This will open a small bootmenu where you can choose
565 between several preconfigured video configs. If you need any special boot
566 options you can append them to the command-line. For instance <c>boot cd
567 /boot/pegasos video=radeonfb:1280x1024@75 mem=256M</c>. The complete list of
568 kernel appends (in case something goes wrong and you need it) is preconfigured
569 in the kernel with <c>console=ttyS0,115200 console=tty0 init=/linuxrc
570 looptype=squashfs loop=/livecd.squashfs udev nodevfs cdroot root=/dev/ram0</c>.

577 <title>Alternative: Booting the Installation CD with BootX</title>
578 <body>
579
580 <p>
581 If you have an OldWorld Mac the bootable portion of the livecd can't be used.
582 The most simple solution is to use MacOS to bootstrap into a Linux environment
583 with a tool called BootX. Boot floppies are being prepared for Macs without
584 MacOS, but they are not available at this time.
585 </p>
586
587 <p>
588 First, download <uri link="http://penguinppc.org/projects/bootx/">BootX</uri>
589 and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
590 archive into <c>Extensions Folder</c> and the BootX App Control Panel into
591 <c>Control Panels</c>, both of which are located in your MacOS System Folder.
592 Next, create a folder called "Linux Kernels" in your System folder and copy the
593 <c>G3G4</c> kernel from the CD to this folder. Finally, copy <c>G3G4.igz</c>
594 from the Installation CD <path>boot</path> folder into the MacOS
595 <c>System Folder</c>.
596 </p>
597
598 <p>
599 To prepare BootX, start the BootX App Control Panel. First select the Options
600 dialog and check <c>Use Specified RAM Disk</c> and select <c>G3G4.igz</c> from
601 your System Folder. Continue back to the initial screen and ensure that the
602 ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
603 shown below:
604 </p>
605
606 <pre caption="BootX kernel arguments">
607 cdroot root=/dev/ram0 init=linuxrc loop=livecd.squashfs looptype=squashfs console=tty0 nodevfs udev
608 </pre>
609

630 You will be greeted by a root ("#") prompt on the current console. You can also
631 switch to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get
632 back to the one you started on by pressing Alt-F1. Probably you have to hit
633 Alt-fn-Fx on Apple machines.

637 If you are installing Gentoo on a system with a non-US keyboard, use
638 <c>loadkeys</c> to load the keymap for your keyboard. To list the available
639 keymaps, execute <c>ls /usr/share/keymaps/i386</c>. On NewWorld machines or the
640 Pegasos do not use the keymaps in <path>ppc</path> or <path>mac</path> as they
641 are for ADB-based OldWorld machines.

670 When the Installation CD boots, it tries to detect all your hardware devices and
671 loads the appropriate kernel modules to support your hardware. In the
672 vast majority of cases, it does a very good job. However, in some cases, it may
673 not auto-load the kernel modules you need. If the PCI auto-detection missed some
674 of your system's hardware, you will have to load the appropriate kernel modules
675 manually.

679 In the next example we try to load the <c>airport</c> module. This module
680 supports only the old Airport cards (b-net). AirportExtreme is currently not
681 supported under Linux:

691 <title>Optional: Tweaking Hard Disk Performance</title>
692 <body>
693
694 <p>
695 If you are an advanced user, you might want to tweak the IDE hard disk
696 performance using <c>hdparm</c>. With the <c>-tT</c> options you can
697 test the performance of your disk (execute it several times to get a
698 more precise impression):
699 </p>
700
701 <pre caption="Testing disk performance">
702 # <i>hdparm -tT /dev/hda</i>
703 </pre>
704
705 <p>
706 To tweak, you can use any of the following examples (or experiment
707 yourself) which use <path>/dev/hda</path> as disk (substitute with your
708 disk):
709 </p>
710
711 <pre caption="Tweaking hard disk performance">
712 <comment>Activate DMA:</comment> # <i>hdparm -d 1 /dev/hda</i>

721
722 <p>
723 If you plan on giving other people access to your installation
724 environment or you want to chat using <c>irssi</c> without root privileges (for
725 security reasons), you need to create the necessary user accounts and change
726 the root password.
727 </p>
728
729 <p>
730 To change the root password, use the <c>passwd</c> utility:
731 </p>
732
733 <pre caption="Changing the root password">
734 # <i>passwd</i>
735 New password: <comment>(Enter your new password)</comment>
736 Re-enter password: <comment>(Re-enter your password)</comment>
737 </pre>
738
739 <p>
740 To create a user account, we first enter their credentials, followed by
741 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
742 In the next example, we create a user called &quot;john&quot;.
743 </p>
744
745 <pre caption="Creating a user account">
746 # <i>useradd -m -G users john</i>
747 # <i>passwd john</i>
748 New password: <comment>(Enter john's password)</comment>
749 Re-enter password: <comment>(Re-enter john's password)</comment>
750 </pre>
751
752 <p>
753 You can change your user id from root to the newly created user by using
754 <c>su</c>:

765 <body>
766
767 <p>
768 If you want to view the Gentoo Handbook (either from-CD or online) during the
769 installation, make sure you have created a user account (see <uri
770 link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
771 go to a new terminal and log in.
772 </p>
773
774 <p>
775 If you want to view the documentation on the CD you can immediately run
776 <c>links2</c> to read it:
777 </p>
778
779 <pre caption="Viewing the on-CD documentation">
780 # <i>links2 /mnt/cdrom/docs/html/index.html</i>
781 </pre>
782
783 <p>
784 However, it is preferred that you use the online Gentoo Handbook as it will be
785 more recent than the one provided on the CD. You can view it using <c>links2</c>
786 as well, but only after having completed the <e>Configuring your Network</e>
787 chapter (otherwise you won't be able to go on the Internet to view the
788 document):
789 </p>
790
791 <pre caption="Viewing the Online Documentation">
792 # <i>links2 http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml</i>
793 </pre>
794

796 You can go back to your original terminal by pressing <c>Alt-F1</c>.

802 <title>Optional: Starting the SSH Daemon</title>
803 <body>
804
805 <p>
806 If you want to allow other users to access your computer during the
807 Gentoo installation (perhaps because those users are going to help you
808 install Gentoo, or even do it for you), you need to create a user
809 account for them and perhaps even provide them with your root password
810 (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
811 </p>
812
813 <p>
814 To fire up the SSH daemon, execute the following command:
815 </p>
816
817 <pre caption="Starting the SSH daemon">
818 # <i>/etc/init.d/sshd start</i>
819 </pre>
820
821 <p>
822 To be able to use sshd, you first need to set up your networking. Continue with
823 the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
