62    
63 swift 1.1 <p>
64 swift 1.28 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
65 swift 1.24 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 neysx 1.45 <!--
71 swift 1.24 <p>
72 swift 1.28 All Installation CDs allow you to boot, set up networking, initialize your
73 swift 1.24 partitions and start installing Gentoo from the Internet. We currently provide
74 neysx 1.44 two Installation CDs which are equally suitable to install Gentoo from, as long
75 swift 1.28 as you're planning on performing an Internet-based installation using the
76     latest version of the available packages.
77 swift 1.24 </p>
78    
79     <p>
80 swift 1.26 If you wish to install Gentoo without a working Internet connection, please use
81 swift 1.24 the installation instructions described in the <uri
82 nightmorph 1.47 link="2008.0/index.xml">Gentoo 2008.0 Handbooks</uri>.
83 swift 1.24 </p>
84    
85     <p>
86 swift 1.28 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 swift 1.37 as the Minimal Installation CD. Additionally, it contains several stage3
98     tarballs (optimized for the individual subarchitectures).
99 swift 1.28 </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.

115 nightmorph 1.47 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.

146 fox2mike 1.40 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

177    
178     <p>
179 neysx 1.38 You might find a Package CD on one of our mirrors. This CD is not an
180 swift 1.28 Installation CD but an additional resource that can be exploited during a
181 neysx 1.38 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 swift 1.28 </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 nightmorph 1.43 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 swift 1.24 </p>
231    
232     <p>
233 nightmorph 1.47 Inside that directory you'll find ISO files. Those are full CD images which you
234 neysx 1.38 can write on a CD-R.
235 swift 1.1 </p>
236    
237     <p>
238 nightmorph 1.47 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 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 jkt 1.39 $ <i>gpg --keyserver subkeys.pgp.net --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 nightmorph 1.46 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>.

286 swift 1.1 <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 swift 1.28 operating environment for OpenVMS, Tru64 UNIX, and Linux operating systems. ARC
298 swift 1.1 is based on the Advanced RISC Computing (ARC) specification, which provides
299 vapier 1.14 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 swift 1.1 </p>
303    
304     <p>
305 vapier 1.29 If your Alpha system supports both SRM and ARCs (ARC, AlphaBIOS, ARCSBIOS) you
306 swift 1.1 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 nightmorph 1.49 Now to boot an Alpha Installation CD, put the CD-ROM in the tray and reboot the
314 swift 1.28 system. You can use SRM to boot the Installation CD. If you cannot do that, you
315 nightmorph 1.49 will have to use <c>MILO</c>.
