58 <title>The Gentoo Installation CD</title>
59 <subsection>
60 <title>Introduction</title>
61 <body>
62
63 <p>
64 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
65 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
66 During the boot process your hardware is detected and the appropriate drivers
67 are loaded. They are maintained by Gentoo developers.
68 </p>
69
70 <p>
71 All Installation CDs allow you to boot, set up networking, initialize your
72 partitions and start installing Gentoo from the Internet.
73 </p>
74
75 <!--
76 <impo>
77 If you wish to install Gentoo without a working Internet connection, please use
78 the installation instructions described in the <uri
79 link="2008.0/index.xml">Gentoo 2008.0 Handbooks</uri>.
80 </impo>
81
82 <p>
83 The two Installation CDs we currently provide are:
84 </p>
85
86 <ul>
87 <li>
88 The Gentoo Minimal Installation CD, a small, no-nonsense, bootable CD which
89 sole purpose is to boot the system, prepare the networking and continue
90 with the Gentoo installation.
91 </li>
92 <li>
93 The Gentoo Universal Installation CD, a bootable CD with the same abilities
94 as the Minimal Installation CD. Additionally, it contains several stage3
95 tarballs (optimized for the individual subarchitectures).
96 </li>
97 </ul>
98
99 <p>
100 To help you decide which Installation CD you need, we have written down the
101 major advantages and disadvantages of each Installation CD.

112 The Minimal Installation CD is called <c><keyval id="min-cd-name"/></c> and
113 takes up only <keyval id="min-cd-size"/> MB of diskspace. You can use this
114 Installation CD to install Gentoo, but <e>only</e> with a working Internet
115 connection.

142 <p>
143 The Universal Installation CD is called <c>install-alpha-universal-2008.0.iso</c>
144 and consumes about 316 MB on a CD. You can use this Installation CD to install
145 Gentoo, and you can even use it to install Gentoo without a working internet
146 connection.

176 <p>
177 You might find a Package CD on one of our mirrors. This CD is not an
178 Installation CD but an additional resource that can be exploited during a
179 networkless installation. It contains prebuilt packages (also known as the GRP
180 set) that allow you to easily and quickly install additional applications
181 (such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless
182 Gentoo installation.
183 </p>
184
185 <p>
186 If you intend to use the Packages CD to quickly install additional software,
187 make sure that you use the same subarchitecture as the stage3 tarball you use.

193 <title>The Stage3 Tarball</title>
194 <body>
195
196 <p>
197 A stage3 tarball is an archive containing a minimal Gentoo environment, suitable
198 to continue the Gentoo installation using the instructions in this manual.
199 Previously, the Gentoo Handbook described the installation using one of three
200 stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
201 official installation method uses the stage3 tarball. If you are interested in
202 performing a Gentoo installation using a stage1 or stage2 tarball, please read
203 the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo
204 Using a Stage1 or Stage2 Tarball?</uri>
205 </p>
206
207 <p>
208 Stage3 tarballs can be downloaded from <path><keyval
209 id="release-dir"/>current-stage3/</path> on any of the <uri
210 link="/main/en/mirrors.xml">Official Gentoo Mirrors</uri> and are not provided
211 on the LiveCD.

219 <title>Download, Burn and Boot a Gentoo Installation CD</title>
220 <subsection>
221 <title>Downloading and Burning the Installation CDs</title>
222 <body>
223
224 <p>
225 You have chosen to use a Gentoo Installation CD. We'll first start by
226 downloading and burning the chosen Installation CD. We previously discussed
227 the several available Installation CDs, but where can you find them?
228 </p>
229
230 <p>
231 You can download any of the Installation CDs from one of our <uri
232 link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
233 the <path><keyval id="release-dir"/>current-iso/</path> directory.
234 </p>
235
236 <p>
237 Inside that directory you'll find ISO files. Those are full CD images which you
238 can write on a CD-R.
239 </p>
240
241 <p>
242 In case you wonder if your downloaded file is corrupted or not, you can check
243 its MD5 checksum and compare it with the MD5 checksum we provide (such as
244 <path><keyval id="min-cd-name"/>.DIGESTS</path>). You can check the MD5 checksum
245 with the <c>md5sum</c> tool under Linux/Unix or <uri
246 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
247 </p>
248
249 <p>
250 Another way to check the validity of the downloaded file is to use GnuPG to
251 verify the cryptographic signature that we provide (the file ending with
252 <path>.asc</path>). Download the signature file and obtain the public key:
253 </p>
254
255 <pre caption="Obtaining the public key">
256 $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 2D182910</i>
257 </pre>
258
259 <p>
260 Now verify the signature:
261 </p>
262
263 <pre caption="Verify the files">
264 <comment>(Verify the cryptographic signature)</comment>
265 $ <i>gpg --verify &lt;downloaded iso.DIGESTS.asc&gt;</i>
266 <comment>(Verify the checksum)</comment>
267 $ <i>sha1sum -c &lt;downloaded iso.DIGESTS.asc&gt;</i>
268 </pre>
269
270 <p>
271 To burn the downloaded ISO(s), you have to select raw-burning. How you
272 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
273 <c>K3B</c> here; more information can be found in our <uri
274 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
275 </p>
276
277 <ul>
278 <li>
279 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
280 file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's
281 device path).
282 </li>
283 <li>
284 With K3B, select <c>Tools</c> &gt; <c>Burn CD Image</c>. Then you can locate
285 your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
286 </li>
287 </ul>

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

341 </pre>
342
343 <p>
344 You should have a root ("#") prompt on the current console and can also switch
345 to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you
346 started on by pressing Alt-F1.
