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>

70 <!--
71 <p>
72 All Installation CDs allow you to boot, set up networking, initialize your
73 partitions and start installing Gentoo from the Internet. We currently provide
74 two Installation CDs which are equally suitable to install Gentoo from, as long
75 as you're planning on performing an Internet-based installation using the
76 latest version of the available packages.
77 </p>
78
79 <p>
80 If you wish to install Gentoo without a working Internet connection, please use
81 the installation instructions described in the <uri
82 link="2008.0/index.xml">Gentoo 2008.0 Handbooks</uri>.
83 </p>
84
85 <p>
86 The two Installation CDs we currently provide are:
87 </p>
88
89 <ul>
90 <li>
91 The Gentoo Minimal Installation CD, a small, no-nonsense, bootable CD which
92 sole purpose is to boot the system, prepare the networking and continue
93 with the Gentoo installation.
94 </li>
95 <li>
96 The Gentoo Universal Installation CD, a bootable CD with the same abilities
97 as the Minimal Installation CD. Additionally, it contains several stage3
98 tarballs (optimized for the individual subarchitectures).
99 </li>
100 </ul>
101
102 <p>
103 To help you decide which Installation CD you need, we have written down the
104 major advantages and disadvantages of each Installation CD.

114 <p>
115 The Minimal Installation CD is called <c><keyval id="min-cd-name"/></c> and
116 takes up only 47 MB of diskspace. You must use this Installation CD to install
117 Gentoo, and you need a working Internet connection.

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

178 <p>
179 You might find a Package CD on one of our mirrors. This CD is not an
180 Installation CD but an additional resource that can be exploited during a
181 networkless installation. It contains prebuilt packages (also known as the GRP
182 set) that allow you to easily and quickly install additional applications
183 (such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless
184 Gentoo installation.
185 </p>
186
187 <p>
188 If you intend to use the Packages CD to quickly install additional software,
189 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>

214 <title>Download, Burn and Boot a Gentoo Installation CD</title>
215 <subsection>
216 <title>Downloading and Burning the Installation CDs</title>
217 <body>
218
219 <p>
220 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 </p>
224
225 <p>
226 You can download any of the Installation CDs (and, if you want to, a Packages CD
227 as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
228 Installation CDs are located in the <path><keyval
229 id="release-dir"/>installcd</path> directory.
230 </p>
231
232 <p>
233 Inside that directory you'll find ISO files. Those are full CD images which you
234 can write on a CD-R.
235 </p>
236
237 <p>
238 In case you wonder if your downloaded file is corrupted or not, you can check
239 its MD5 checksum and compare it with the MD5 checksum we provide (such as
240 <path><keyval id="min-cd-name"/>.DIGESTS</path>). You can check the MD5 checksum
241 with the <c>md5sum</c> tool under Linux/Unix or <uri
242 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
243 </p>
244
245 <p>
246 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 $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 17072058</i>
253 </pre>
254
255 <p>
256 Now verify the signature:
257 </p>
258
259 <pre caption="Verify the cryptographic signature">
260 $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
261 </pre>
262
263 <p>
264 To burn the downloaded ISO(s), you have to select raw-burning. How you
265 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 </p>
269
270 <ul>
271 <li>
272 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 device path).
275 </li>
276 <li>
277 With K3B, select <c>Tools</c> &gt; <c>Burn CD Image</c>. Then you can locate
278 your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
279 </li>
280 </ul>

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

334 </pre>
335
336 <p>
337 You should have a root ("#") prompt on the current console and can also switch
338 to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you
339 started on by pressing Alt-F1.
