61 swift 1.24 <subsection>
62     <title>Introduction</title>
63     <body>
64    
65 swift 1.1 <p>
66 swift 1.28 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
67 swift 1.24 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
68     During the boot process your hardware is detected and the appropriate drivers
69     are loaded. They are maintained by Gentoo developers.
70     </p>
71    
72     <p>
73 swift 1.28 All Installation CDs allow you to boot, set up networking, initialize your
74 swift 1.24 partitions and start installing Gentoo from the Internet. We currently provide
75 swift 1.28 two Installation CDs which are equaly suitable to install Gentoo from, as long
76     as you're planning on performing an Internet-based installation using the
77     latest version of the available packages.
78 swift 1.24 </p>
79    
80     <p>
81 swift 1.26 If you wish to install Gentoo without a working Internet connection, please use
82 swift 1.24 the installation instructions described in the <uri
83 swift 1.34 link="2005.1/index.xml">Gentoo 2005.1 Handbooks</uri>.
84 swift 1.24 </p>
85    
86     <p>
87 swift 1.28 The two Installation CDs we currently provide are:
88     </p>
89    
90     <ul>
91     <li>
92     The Gentoo Minimal Installation CD, a small, no-nonsense, bootable CD which
93     sole purpose is to boot the system, prepare the networking and continue
94     with the Gentoo installation.
95     </li>
96     <li>
97     The Gentoo Universal Installation CD, a bootable CD with the same abilities
98 swift 1.37 as the Minimal Installation CD. Additionally, it contains several stage3
99     tarballs (optimized for the individual subarchitectures).
100 swift 1.28 </li>
101     </ul>
102    
103     <p>
104     To help you decide which Installation CD you need, we have written down the
105     major advantages and disadvantages of each Installation CD.

114     <p>
115 swift 1.34 The Minimal Installation CD is called <c>install-alpha-minimal-2005.1.iso</c>
116 swift 1.28 and takes up only 54 MB of diskspace. You can use this Installation CD to
117     install Gentoo, but always with a working Internet connection only.

146 swift 1.28 and consumes the entire surface of a 650 MB CD. You can use this Installation CD
147     to install Gentoo, and you can even use it to install Gentoo without a working
148     internet connection, just in case you want to bring Gentoo to another PC than
149     the one you are currently installing Gentoo on :)

177    
178     <p>
179     You might find a so-called Package CD on one of our mirrors. This CD is no
180     Installation CD but an additional resource that can be exploited during a
181     networkless installation. It contains prebuilt packages (the so-called GRP set)
182     that allows you to easily and quickly install additional applications (such as
183     OpenOffice.org, KDE, GNOME, ...) immediately after the networkless Gentoo
184     installation.
185     </p>
186    
187 swift 1.36 <p>
188     If you intend to use the Packages CD to quickly install additional software,
189 swift 1.37 make sure that you use the same subarchitecture as the stage3 tarball you use.

195     <title>The Stage3 Tarball</title>
196     <body>
197    
198     <p>
199     A stage3 tarball is an archive containing a minimal Gentoo environment, suitable
200     to continue the Gentoo installation using the instructions in this manual.
201     Previously, the Gentoo Handbook described the installation using one of three
202     stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
203     official installation method uses the stage3 tarball. If you are interested in
204     performing a Gentoo installation using a stage1 or stage2 tarball, please read
205     the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo
206     Using a Stage1 or Stage2 Tarball?</uri>

216 swift 1.28 <title>Downloading and Burning the Installation CDs</title>
217 swift 1.1 <body>
218    
219     <p>
220 swift 1.28 You have chosen to use a Gentoo Installation CD. We'll first start by
221     downloading and burning the chosen Installation CD. We previously discussed
222     the several available Installation CDs, but where can you find them?
223 swift 1.1 </p>
224    
225     <p>
226 swift 1.28 You can download any of the Installation CDs (and, if you want to, a Packages
227     CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
228 swift 1.34 Installation CDs are located in the <path>releases/alpha/2005.1/installcd</path>
229 swift 1.28 directory.
230 swift 1.24 </p>
231    
232     <p>
233     Inside that directory you'll find so-called ISO-files. Those are full CD images
234     which you can write on a CD-R.
235 swift 1.1 </p>
236    
237     <p>
238     In case you wonder if your downloaded file is corrupted or not, you can
239     check its MD5 checksum and compare it with the MD5 checksum we provide (such as
240 swift 1.34 <path>install-alpha-minimal-2005.1.iso.md5</path>). You can check the MD5
241 swift 1.28 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
242 neysx 1.11 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
243 swift 1.1 </p>
244    
245     <p>
246 swift 1.8 Another way to check the validity of the downloaded file is to use GnuPG to
247     verify the cryptographic signature that we provide (the file ending with
248     <path>.asc</path>). Download the signature file and obtain the public key:
249     </p>
250    
251     <pre caption="Obtaining the public key">
252 swift 1.12 $ <i>gpg --keyserver pgp.mit.edu --recv-keys 17072058</i>
253 swift 1.8 </pre>
254    
255     <p>
256     Now verify the signature:
257     </p>
258    
259     <pre caption="Verify the cryptographic signature">
260 swift 1.12 $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
261 swift 1.8 </pre>
262    
263     <p>
264 swift 1.1 To burn the downloaded ISO(s), you have to select raw-burning. How you
265 swift 1.9 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
266     <c>K3B</c> here; more information can be found in our <uri
267     link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
268 swift 1.1 </p>
269    
270     <ul>
271     <li>
272 swift 1.24 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
273     file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's
274 swift 1.27 device path).
275 swift 1.1 </li>
276 swift 1.2 <li>
277 bennyc 1.5 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
278     you can locate your ISO file within the 'Image to Burn' area. Finally click
279 swift 1.2 <c>Start</c>.

286 swift 1.28 <title>Booting the Installation CD</title>
287 swift 1.1 <body>
288    
289     <p>
290     When your Alpha is powered on, the first thing that gets started is the
291     firmware. It is loosely synonymous with the BIOS software on PC systems. There
292     are two types of firmware on Alpha systems: SRM (<e>Systems Reference
293     Manual</e>) and ARC (<e>Advanced Risc Console</e>).
294     </p>
295    
296     <p>
297     SRM is based on the Alpha Console Subsystem specification, which provides an
298 swift 1.28 operating environment for OpenVMS, Tru64 UNIX, and Linux operating systems. ARC
299 swift 1.1 is based on the Advanced RISC Computing (ARC) specification, which provides
300 vapier 1.14 an operating environment for Windows NT. You can find a
301     <uri link="http://www.alphalinux.org/faq/SRM-HOWTO/">detailed guide</uri> on
302     using SRM over at the Alpha Linux website.
303 swift 1.1 </p>
304    
305     <p>
306 vapier 1.29 If your Alpha system supports both SRM and ARCs (ARC, AlphaBIOS, ARCSBIOS) you
307 swift 1.1 should follow <uri link="http://www.alphalinux.org/faq/x31.html">these
308     instructions</uri> for switching to SRM. If your system already uses SRM, you
309     are all set. If your system can only use ARCs (Ruffian, nautilus, xl, etc.) you
310     will need to choose <c>MILO</c> later on when we are talking about bootloaders.
311     </p>
312    
313     <p>
314 swift 1.28 Now to boot an Alpha Installation CD, put the CD-ROM in the tray and reboot the
315     system. You can use SRM to boot the Installation CD. If you cannot do that, you
316     will have to use <c>MILO</c>. If you don't have <c>MILO</c> installed already,
317     use one of the precompiled <c>MILO</c> images available on <uri
318 swift 1.1 link="http://dev.gentoo.org/~taviso/milo/">taviso's homepage</uri>.

355     <p>
356 swift 1.28 When the Installation CD boots, it tries to detect all your hardware devices and
357 swift 1.1 loads the appropriate kernel modules to support your hardware. In the
358 swift 1.28 vast majority of cases, it does a very good job. However, in some cases it may
359     not auto-load the kernel
360 swift 1.1 modules you need. If the PCI auto-detection missed some of your system's
361     hardware, you will have to load the appropriate kernel modules manually.
362     </p>
363    
364     <p>
365     In the next example we try to load the <c>8139too</c> module (support for
366     certain kinds of network interfaces):

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

406    
407     <p>
408     If you plan on giving other people access to your installation
409     environment or you want to chat using <c>irssi</c> without root privileges (for
410     security reasons), you need to create the necessary user accounts and change
411     the root password.
412     </p>
413    
414     <p>
415     To change the root password, use the <c>passwd</c> utility:

422     </pre>
423    
424     <p>
425 swift 1.4 To create a user account, we first enter their credentials, followed by
426 swift 1.1 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
427     In the next example, we create a user called &quot;john&quot;.

451    
452     <p>
453     If you want to view the Gentoo Handbook (either from-CD or online) during the
454     installation, make sure you have created a user account (see <uri
455 neysx 1.19 link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
456 swift 1.13 go to a new terminal and log in.

458    
459     <p>
460     If you want to view the documentation on the CD you can immediately run
