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.

106 <title>The Gentoo Installation CDs</title>
107 <subsection>
108 <title>Introduction</title>
109 <body>
110
111 <p>
112 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
113 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
114 During the boot process your hardware is detected and the appropriate drivers
115 are loaded. They are maintained by Gentoo developers.
116 </p>
117
118 <p>
119 All Installation CDs allow you to boot, set up networking, initialize your
120 partitions and start installing Gentoo from the Internet. We currently provide
121 two Installation CDs which are equally suitable to install Gentoo from, as long
122 as you're planning on performing an Internet-based installation using the
123 latest version of the available packages.
124 </p>
125
126 <impo>
127 If you wish to install Gentoo without a working Internet connection, or would
128 like to use one of the provided installers, please use the installation
129 instructions described in the <uri link="2008.0/">Gentoo 2008.0
130 Handbooks</uri>.
131 </impo>
132
133 <p>
134 The Installation CDs that we currently provide are:
135 </p>
136
137 <ul>
138 <li>
139 The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable
140 CD which sole purpose is to boot the system, prepare the networking and
141 continue with the Gentoo installation.
142 </li>
143 <li>
144 The Gentoo <e>Installer LiveCD</e> contains everything you need to install
145 Gentoo. It provides a graphical environment, a graphical as well as console
146 based installer which automatically carries out the installation for you,
147 and of course, the installation instructions for your architecture.
148 </li>
149 </ul>
150
151 <p>
152 To help you decide which Installation CD you need, we have written down the
153 major advantages and disadvantages of each Installation CD.

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

222 <title>The Stage3 Tarball</title>
223 <body>
224
225 <p>
226 A stage3 tarball is an archive containing a minimal Gentoo environment,
227 suitable to continue the Gentoo installation using the instructions in this
228 manual. Previously, the Gentoo Handbook described the installation using one of
229 three stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
230 official installation method uses the stage3 tarball. If you are interested in
231 performing a Gentoo installation using a stage1 or stage2 tarball, please read
232 the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo
233 Using a Stage1 or Stage2 Tarball?</uri>
234 </p>
235
236 <p>
237 Stage3 tarballs can be downloaded from <path><keyval
238 id="release-dir"/>stages/</path> on any of the <uri
239 link="/main/en/mirrors.xml">Official Gentoo Mirrors</uri> and are not provided
240 on the LiveCD.

248 <title>Download, Burn and Boot a Gentoo Installation CD</title>
249 <subsection>
250 <title>Downloading and Burning the Installation CDs</title>
251 <body>
252
253 <p>
254 You have chosen to use a Gentoo Installation CD. We'll first start by
255 downloading and burning the chosen Installation CD. We previously discussed
256 the several available Installation CDs, but where can you find them?
257 </p>
258
259 <p>
260 You can download any of the Installation CDs from one of our <uri
261 link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
262 the <path><keyval id="release-dir"/>installcd/</path> directory.
263 </p>
264
265 <p>
266 Inside that directory you'll find ISO files. Those are full CD images which you
267 can write on a CD-R.
268 </p>
269
270 <p>
271 In case you wonder if your downloaded file is corrupted or not, you can check
272 its MD5 checksum and compare it with the MD5 checksum we provide (such as
273 <path><keyval id="min-cd-name"/>.DIGESTS</path>). You can check the MD5
274 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
275 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
276 </p>
277
278 <p>
279 Another way to check the validity of the downloaded file is to use GnuPG to
280 verify the cryptographic signature that we provide (the file ending with
281 <path>.asc</path>). Download the signature file and obtain the public key:
282 </p>
283
284 <pre caption="Obtaining the public key">
285 $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 17072058</i>
286 </pre>
287
288 <p>
289 Now verify the signature:
290 </p>
291
292 <pre caption="Verify the cryptographic signature">
293 $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
294 </pre>
295
296 <p>
297 To burn the downloaded ISO(s), you have to select raw-burning. How you
298 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
299 <c>K3B</c> here; more information can be found in our <uri
300 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
301 </p>
302
303 <ul>
304 <li>
305 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
306 file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's
307 device path).
308 </li>
309 <li>
310 With K3B, select <c>Tools</c> &gt; <c>Burn CD Image</c>. Then you can locate
311 your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
312 </li>
313 </ul>

315 </body>
316 </subsection>
317 <subsection>
318 <title>Booting the Installation CD</title>
319 <body>
320
321 <p>
322 Once you have burnt your installation CD, it is time to boot it.
323 Remove all CDs from your CD drives, reboot your system and enter the BIOS.
324 This is usually done by hitting DEL, F1 or ESC, depending on your BIOS. Inside
325 the BIOS, change the boot order so that the CD-ROM is tried before the hard
326 disk. This is often found under "CMOS Setup". If you don't do this, your system
327 will just reboot from the hard disk, ignoring the CD-ROM.
328 </p>
329
330 <p>
331 Now place the installation CD in the CD-ROM drive and reboot. You should see a
332 boot prompt. At this screen, you can hit Enter to begin the boot process with
333 the default boot options, or boot the Installation CD with custom boot options
334 by specifying a kernel followed by boot options and then hitting Enter.
335 </p>
336
337 <p>
338 Specifying a kernel? Yes, we provide several kernels on our Installation CDs.
339 The default one is <c>gentoo</c>. Other kernels are for specific hardware needs
340 and the <c>-nofb</c> variants which disable framebuffer.
341 </p>
342
343 <p>
344 Below you'll find a short overview on the available kernels:
345 </p>
346
347 <table>
348 <tr>
349 <th>Kernel</th>
350 <th>Description</th>
351 </tr>
352 <tr test="func:keyval('arch')='x86'">
353 <ti>gentoo</ti>
354 <ti>Default 2.6 kernel with support for multiple CPUs</ti>
355 </tr>
356 <tr test="func:keyval('arch')='AMD64'">
357 <ti>gentoo</ti>
358 <ti>
359 Default kernel with support for K8 CPUS (including NUMA support) and EM64T
360 CPUs
361 </ti>
362 </tr>
363 <tr>
364 <ti>gentoo-nofb</ti>
365 <ti>Same as <c>gentoo</c> but without framebuffer support</ti>
366 </tr>
367 <tr>
368 <ti>memtest86</ti>
369 <ti>Test your local RAM for errors</ti>
370 </tr>
371 </table>
372
373 <p>
374 You can also provide kernel options. They represent optional settings you can
375 (de)activate at will.
376 </p>
377
378 </body>
379
380 <body>
381 <include href="hb-install-kernelparams.xml"/>
382 </body>
383
384 <body>
385
386 <note>
387 The CD will check for "no*" options before "do*" options, so that you can
388 override any option in the exact order you specify.
389 </note>
390
391 <p>
392 Now boot your CD, select a kernel (if you are not happy with the default
393 <c>gentoo</c> kernel) and boot options. As an example, we show you how
394 to boot the <c>gentoo</c> kernel, with <c>dopcmcia</c> as kernel
395 parameters:
396 </p>
397
398 <pre caption="Booting an Installation CD">
399 boot: <i>gentoo dopcmcia</i>
400 </pre>
401
402 <p>
403 You will then be greeted with a boot screen and progress bar. If you are
404 installing Gentoo on a system with a non-US keyboard, make sure you immediately
405 press Alt-F1 to switch to verbose mode and follow the prompt. If no selection
406 is made in 10 seconds the default (US keyboard) will be accepted and the boot
407 process will continue. Once the boot process completes, you will be
408 automatically logged in to the "Live" Gentoo Linux as "root", the super user.
409 You should have a root ("#") prompt on the current console and can also switch
410 to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one
411 you started on by pressing Alt-F1.
412 </p>
413
414 <p>
415 Now continue with <uri link="#hardware">Extra Hardware Configuration</uri>.
