As announced on the list (http://archives.gentoo.org/gentoo-doc/msg_e721be404c6a5ae8ce5c5bf02f45381c.xml), assume all arches are using the libata framework, so sd* everywhere. includes updating block device and partition descriptions. also added a new included file for boot config (starting sshd, hdparm, etc). synced up several wayward files, including sparc. also changed/dropped usage of some now useless keys, since everyone's using sd*. lots of intensive, invasive changes. and i never even used sed once.

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.

113
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.

144 <p>
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, just in case you want to bring Gentoo to another PC than the one
149 you are currently installing Gentoo on :)

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

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

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

286 <title>Booting the Installation CD</title>
287 <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 operating environment for OpenVMS, Tru64 UNIX, and Linux operating systems. ARC
299 is based on the Advanced RISC Computing (ARC) specification, which provides
300 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 </p>
304
305 <p>
306 If your Alpha system supports both SRM and ARCs (ARC, AlphaBIOS, ARCSBIOS) you
307 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 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 link="http://dev.gentoo.org/~taviso/milo/">taviso's homepage</uri>.

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