61	Still interested in trying out Gentoo? Well, then it is now time to
62	choose the installation medium you want to use. Yes, you have the
63	choice, no, they are not all equal, and yes, the result is always the same: a
64	Gentoo base system.
65	</p>
66
67	<p>
68	The installation media we will describe are:
69	</p>
70
71	<ul>
72	<li>Gentoo's Minimal LiveCD</li>
73	<li>Gentoo's Universal LiveCD</li>
74	</ul>
75
76	<p>
77	Every single media has its advantages and disadvantages. We will list
78	the pros and cons of every medium so you have all the information to
79	make a justified decision. But before we continue, let's explain our
80	three-stage installation.

86	<title>The Three Stages</title>
87	<body>
88
89	<p>
90	Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
91	The one you choose depends on how much of the system you want to compile
92	yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
93	build the entire system from scratch. The <e>stage2</e> tarball is used for
94	building the entire system from a bootstrapped "semi-compiled" state.
95	The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
96	been built for you. As we will explain later, you can also install
97	Gentoo without compiling anything (except your kernel and some optional
98	packages). If you want this, you have to use a <e>stage3</e> tarball.
99	</p>
100
101	<p>
102	Now what stage do you have to choose?
103	</p>
104
105	<p>
106	Starting from a <e>stage1</e> allows you to have total control over the
107	optimization settings and optional build-time functionality that is
108	initially enabled on your system. This makes <e>stage1</e> installs good for
109	power users who know what they are doing. It is also a great
110	installation method for those who would like to know more about the
111	inner workings of Gentoo Linux.
112	</p>
113
114	<p>
115	A <e>stage1</e> installation can only be performed when you have a working
116	Internet connection.

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

238	Write down (or remember) what stage you want to use. You need this later when
239	you decide what LiveCD (or other installation medium) you want to use. You might
240	be interested to know that, if you decide to use different optimization settings
241	after having installed Gentoo, you will be able to recompile your entire system
242	with the new optimization settings.
243	</p>
244

520	<p>
521	If you are an advanced user, you might want to tweak the IDE hard disk
522	performance using <c>hdparm</c>. With the <c>-tT</c> options you can
523	test the performance of your disk (execute it several times to get a
524	more precise impression):

532	To tweak, you can use any of the following examples (or experiment
533	yourself) which use <path>/dev/hda</path> as disk (substitute with your
534	disk):

547
548	<p>
549	If you plan on giving other people access to your installation
550	environment or you want to chat using <c>irssi</c> without root privileges (for
551	security reasons), you need to create the necessary user accounts and change
552	the root password.
553	</p>
554
555	<p>
556	To change the root password, use the <c>passwd</c> utility:

562	Re-enter password: <comment>(Re-enter your password)</comment>
563	</pre>
564
565	<p>
566	To create a user account, we first enter their credentials, followed by
567	its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
568	In the next example, we create a user called "john".

594	If you want to view the Gentoo Handbook (either from-CD or online) during the
595	installation, make sure you have created a user account (see <uri
596	link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
597	go to a new terminal and log in.
598	</p>

611	more recent than the one provided on the CD. You can view it using <c>links2</c>
612	as well, but only after having completed the <e>Configuring your Network</e>

632	If you want to allow other users to access your computer during the
633	Gentoo installation (perhaps because those users are going to help you
634	install Gentoo, or even do it for you), you need to create a user
635	account for them and perhaps even provide them with your root password
636	(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
637	</p>
