64The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
65self-sustained Gentoo environment. They allow you to boot Linux from the CD.
66During the boot process your hardware is detected and the appropriate drivers
67are loaded. They are maintained by Gentoo developers.

29Check the following requirements before you 69
30continue with the Gentoo installation: 70<p>
71All Installation CDs allow you to boot, set up networking, initialize your
72partitions and start installing Gentoo from the Internet.

53Still interested in trying out Gentoo? Well, then it is now time to
54choose the installation medium you want to use. Yes, you have the
55choice, no, they are not all equal, and yes, the result is always the same: a
56Gentoo base system.

74<title>The Three Stages</title>
75<body> 109<body>
76 110
77<p>
78Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
79The one you choose depends on how much of the system you want to compile
80yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
81build the entire system from scratch. The <e>stage2</e> tarball is used for
82building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
83The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
84been built for you.
85</p> 111<p>
86 112The Minimal Installation CD is called <c><keyval id="min-cd-name"/></c> and
113takes up only <keyval id="min-cd-size"/> MB of diskspace. You can use this
114Installation CD to install Gentoo, but <e>only</e> with a working Internet
115connection.
87<p> 116</p>
88Now what stage do you have to choose? 117<!--
89</p>
90
91<p>
92Starting from a <e>stage1</e> allows you to have total control over the
93optimization settings and optional build-time functionality that is
94initially enabled on your system. This makes <e>stage1</e> installs good for
95power users who know what they are doing. It is also a great
96installation method for those who would like to know more about the
97inner workings of Gentoo Linux.
98</p>
99
100<p>
101A <e>stage1</e> installation can only be performed when you have a working
102Internet connection.

194settings that we chose for you (which to be honest, are good settings
195and were carefully chosen to enhance performance while maintaining
196stability). <e>stage3</e> is also required if you want to install Gentoo using
197prebuilt packages or without a network connection.

224Write down (or remember) what stage you want to use. You need this later when

226be interested to know that, if you decide to use different optimization settings
227after having installed Gentoo, you will be able to recompile your entire system
228with the new optimization settings.

177You might find a Package CD on one of our mirrors. This CD is not an
178Installation CD but an additional resource that can be exploited during a
179networkless installation. It contains prebuilt packages (also known as the GRP
180set) that allow you to easily and quickly install additional applications
181(such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless
182Gentoo installation.

184
185<p>
186If you intend to use the Packages CD to quickly install additional software,
187make sure that you use the same subarchitecture as the stage3 tarball you use.

199Previously, the Gentoo Handbook described the installation using one of three
200stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the

406When the Live CD boots, it tries to detect all your hardware devices and
407loads the appropriate kernel modules to support your hardware. In the
408vast majority of cases, it does a very good job. However, in some cases (the
409SPARC LiveCDs don't even do autodetection), it may not auto-load the kernel
410modules you need. If the PCI auto-detection missed some of your system's
411hardware, you will have to load the appropriate kernel modules manually.
412</p>
413
414<p>
415In the next example we try to load the <c>8139too</c> module (support for
416certain kinds of network interfaces):

426<title>Optional: Tweaking Hard Disk Performance</title>
427<body>
428 359
429<p>
430If you are an advanced user, you might want to tweak the IDE hard disk
431performance using <c>hdparm</c>. With the <c>-tT</c> options you can
432test the performance of your disk (execute it several times to get a
433more precise impression):
434</p>
435
436<pre caption="Testing disk performance">
437# <i>hdparm -tT /dev/hda</i>
438</pre>
439
440<p>
441To tweak, you can use any of the following examples (or experiment
442yourself) which use <path>/dev/hda</path> as disk (substitute with your
443disk):

455<body>
456
457<p>
458If you plan on giving other people access to your installation
459environment or you want to chat using <c>irssi</c> without root privileges (for
460security reasons), you need to create the necessary user accounts and change
461the root password.
462</p>
463
464<p>
465To change the root password, use the <c>passwd</c> utility:
466</p>
467
468<pre caption="Changing the root password">
469# <i>passwd</i>
470New password: <comment>(Enter your new password)</comment>
471Re-enter password: <comment>(Re-enter your password)</comment>
472</pre>
473
474<p>
475To create a user account, we first enter their credentials, followed by
476its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
477In the next example, we create a user called &quot;john&quot;.
478</p>
479
480<pre caption="Creating a user account">
481# <i>useradd john</i>

484Re-enter password: <comment>(Re-enter john's password)</comment>
485</pre>
486
487<p>
488You can change your user id from root to the newly created user by using

500<body>
501
502<p>
503If you want to view the Gentoo Handbook (either from-CD or online) during the
504installation, make sure you have created a user account (see <uri
505link="#useraccouts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
506go to a new terminal and log in.
507</p>
508
509<p>
510If you want to view the documentation on the CD you can immediately run
511<c>lynx</c> to read it:
512</p>
513
514<pre caption="Viewing the on-CD documentation">
515# <i>lynx /mnt/cdrom/docs/html/index.html</i>
516</pre>
517
518<p>
519However, it is preferred that you use the online Gentoo Handbook as it will be
520more recent than the one provided on the CD. You can view it using <c>lynx</c>
521as well, but only after having completed the <e>Configuring your Network</e>
522chapter (otherwise you won't be able to go on the Internet to view the
523document):

540<p>
541If you want to allow other users to access your computer during the
542Gentoo installation (perhaps because those users are going to help you
543install Gentoo, or even do it for you), you need to create a user
544account for them and perhaps even provide them with your root password
545(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
546</p>
547
548<p>
549To fire up the SSH daemon, execute the following command:

551
552<pre caption="Starting the SSH daemon">

557To be able to use sshd, you first need to setup your networking. Continue with
558the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
