67 swift 1.17 <title>The Gentoo Installation CDs</title>
68 swift 1.1 <subsection>
69 swift 1.14 <title>Introduction</title>
70 swift 1.1 <body>
71    
72     <p>
73 swift 1.17 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
74 swift 1.1 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
75     During the boot process your hardware is detected and the appropriate drivers
76     are loaded. They are maintained by Gentoo developers.
77     </p>
78    
79     <p>
80 swift 1.17 All Installation CDs allow you to boot, set up networking, initialize your
81 swift 1.14 partitions and start installing Gentoo from the Internet. We currently provide
82 swift 1.17 two Installation CDs which are equaly suitable to install Gentoo from, as long
83     as you're planning on performing an Internet-based installation using the
84     latest version of the available packages.
85 swift 1.14 </p>
86    
87     <p>
88 swift 1.15 If you wish to install Gentoo without a working Internet connection, please use
89 swift 1.14 the installation instructions described in the <uri
90 fox2mike 1.29 link="2006.0/index.xml">Gentoo 2006.0 Handbooks</uri>. This is currently not
91 swift 1.14 supported for the PPC64 architecture though.
92 swift 1.1 </p>
93    
94     <p>
95 neysx 1.27 The two Installation CDs that we currently provide are:
96     </p>
97    
98     <ul>
99     <li>
100     The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable
101     CD which sole purpose is to boot the system, prepare the networking and
102     continue with the Gentoo installation.
103     </li>
104     <li>
105     The Gentoo <e>Universal</e> Installation CD, a bootable CD with the same
106     abilities as the Minimal Installation CD. Additionally, it contains
107     several stage3 tarballs (optimized for the individual subarchitectures).
108     </li>
109     </ul>
110    
111     <p>
112     To help you decide which Installation CD you need, we have written down the
113     major advantages and disadvantages of each Installation CD.

122     <p>
123 swift 1.17 The Minimal Installation CD is called
124 fox2mike 1.29 <c>install-ppc64-minimal-2006.0.iso</c> and takes up only 124 MB of
125 swift 1.17 diskspace. You can use this Installation CD to install Gentoo, but always with a
126 swift 1.14 working Internet connection only.

154     The Universal Installation CD is called
155 fox2mike 1.29 <c>install-ppc64-universal-2006.0-32ul.iso</c> and uses 460 MB. You can use
156     this Installation CD to install Gentoo, and you can even use it to install
157     Gentoo without a working internet connection, just in case you want to bring
158     Gentoo to another PC than the one you are currently installing Gentoo on :)

184    
185     <p>
186     A stage3 tarball is an archive containing a minimal Gentoo environment, suitable
187     to continue the Gentoo installation using the instructions in this manual.
188     Previously, the Gentoo Handbook described the installation using one of three
189     stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
190     official installation method uses the stage3 tarball. If you are interested in
191     performing a Gentoo installation using a stage1 or stage2 tarball, please read
192     the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo
193     Using a Stage1 or Stage2 Tarball?</uri>

201 swift 1.17 <title>Download, Burn and Boot a Gentoo Installation CD</title>
202 swift 1.1 <subsection>
203 swift 1.17 <title>Downloading and Burning the Installation CDs</title>
204 swift 1.1 <body>
205    
206     <p>
207 swift 1.17 You have chosen to use a Gentoo Installation CD. We'll first start by
208     downloading and burning the chosen Installation CD. We previously discussed the
209     several available Installation CDs, but where can you find them?
210 swift 1.14 </p>
211    
212     <p>
213 neysx 1.27 You can download any of the Installation CDs (and, if you want to, a Packages
214 swift 1.17 CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
215 neysx 1.27 Installation CDs are located in the
216 fox2mike 1.29 <path>releases/ppc/2006.0/ppc64/installcd</path> directory.
217 swift 1.1 </p>
218    
219     <p>
220 neysx 1.26 Inside that directory you'll find ISO-files. Those are full CD images
221 swift 1.1 which you can write on a CD-R.
222     </p>
223    
224     <p>
225 swift 1.14 In case you wonder if your downloaded file is corrupted or not, you can
226     check its MD5 checksum and compare it with the MD5 checksum we provide (such as
227 fox2mike 1.29 <path>install-ppc64-minimal-2006.0.iso.DIGESTS</path>). You can check the MD5
228 swift 1.1 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
229     link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
230     </p>
231    
232     <p>
233 swift 1.14 Another way to check the validity of the downloaded file is to use GnuPG to
234     verify the cryptographic signature that we provide (the file ending with
235     <path>.asc</path>). Download the signature file and obtain the public key:
236 swift 1.1 </p>
237    
238 swift 1.14 <pre caption="Obtaining the public key">
239 jkt 1.28 $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 17072058</i>
240 swift 1.1 </pre>
241    
242     <p>
243 swift 1.14 Now verify the signature:
244 swift 1.1 </p>
245    
246 swift 1.14 <pre caption="Verify the cryptographic signature">
247     $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
248     </pre>
249 swift 1.1
250     <p>
251     To burn the downloaded ISO(s), you have to select raw-burning. How you
252 swift 1.14 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
253     <c>K3B</c> here; more information can be found in our <uri
254     link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
255 swift 1.1 </p>
256    
257     <ul>
258     <li>
259 swift 1.14 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
260     file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's
261 swift 1.16 device path).
262 swift 1.1 </li>
263     <li>
264 swift 1.14 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
265 swift 1.1 you can locate your ISO file within the 'Image to Burn' area. Finally click
266     <c>Start</c>.
267     </li>
268 swift 1.7 <li>
269     With Mac OS X Panther, launch <c>Disk Utility</c> from
270     <path>Applications/Utilities</path>, select <c>Open</c> from the
271     <c>Images</c> menu, select the mounted disk image in the main window and
272     select <c>Burn</c> in the <c>Images</c> menu.
273     </li>
274     <li>
275     With Mac OS X Jaguar, launch <c>Disk Copy</c> from
276     <path>Applications/Utilities</path>, select <c>Burn Image</c> from the
277     <c>File</c> menu, select the ISO and click the <c>Burn</c> button.
278     </li>
279 swift 1.1 </ul>

291 swift 1.1 </p>
292    
293     <p>
294     You are also able to tweak some kernel options at this prompt. The following

307     <c>radeonfb</c>, <c>rivafb</c>, <c>atyfb</c>, <c>aty128</c> or
308     <c>ofonly</c>. You can follow this tag with the resolution and refreshrate
309     you want to use. For instance <c>video=radeonfb:1280x1024@75</c>. If you are
310     uncertain what to choose, <c>ofonly</c> will most certainly work.

414     <p>
415 swift 1.17 When the Installation CD boots, it tries to detect all your hardware devices and
416 swift 1.1 loads the appropriate kernel modules to support your hardware. In the
417 swift 1.17 vast majority of cases, it does a very good job. However, in some cases it may
418     not auto-load the kernel
419 swift 1.1 modules you need. If the PCI auto-detection missed some of your system's
420     hardware, you will have to load the appropriate kernel modules manually.
421     </p>
422    
423     <p>
424     In the next example we try to load the <c>8139too</c> module (support for
425     certain kinds of network interfaces):

438     <p>
439     If you are an advanced user, you might want to tweak the IDE hard disk
440     performance using <c>hdparm</c>. With the <c>-tT</c> options you can
441     test the performance of your disk (execute it several times to get a

466     <p>
467     If you plan on giving other people access to your installation
468     environment or you want to chat using <c>irssi</c> without root privileges (for
469     security reasons), you need to create the necessary user accounts and change
470     the root password.
471     </p>
472    
473     <p>
474     To change the root password, use the <c>passwd</c> utility:

476    
477     <pre caption="Changing the root password">

481     </pre>
482    
483     <p>
484     To create a user account, we first enter their credentials, followed by
485     its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
486     In the next example, we create a user called &quot;john&quot;.

545     <p>
546     If you want to allow other users to access your computer during the
547     Gentoo installation (perhaps because those users are going to help you
548     install Gentoo, or even do it for you), you need to create a user
549     account for them and perhaps even provide them with your root password
550     (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
551     </p>
552    
553     <p>
554     To fire up the SSH daemon, execute the following command:
555     </p>
556    
557     <pre caption="Starting the SSH daemon">
558     # <i>/etc/init.d/sshd start</i>
559     </pre>
560    
561     <p>
562 swift 1.6 To be able to use sshd, you first need to set up your networking. Continue with
563 swift 1.1 the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
