111     The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
112     self-sustained Gentoo environment. They allow you to boot Linux from the CD.
113     During the boot process your hardware is detected and the appropriate drivers
114     are loaded. They are maintained by Gentoo developers.
115     </p>
116    
117     <p>
118     All Installation CDs allow you to boot, set up networking, initialize your
119 nightmorph 1.17 partitions and start installing Gentoo from the Internet.

225 neysx 1.2 A stage3 tarball is an archive containing a minimal Gentoo environment,
226     suitable to continue the Gentoo installation using the instructions in this
227     manual. Previously, the Gentoo Handbook described the installation using one of
228     three stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
229 neysx 1.1 official installation method uses the stage3 tarball. If you are interested in
230     performing a Gentoo installation using a stage1 or stage2 tarball, please read
231     the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo

247     <title>Download, Burn and Boot a Gentoo Installation CD</title>
248     <subsection>
249     <title>Downloading and Burning the Installation CDs</title>
250     <body>
251    
252     <p>
253 neysx 1.11 You have chosen to use a Gentoo Installation CD. We'll first start by
254     downloading and burning the chosen Installation CD. We previously discussed
255     the several available Installation CDs, but where can you find them?
256 neysx 1.1 </p>
257    
258 nightmorph 1.3 <p>
259 neysx 1.2 You can download any of the Installation CDs from one of our <uri
260     link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
261 nightmorph 1.17 the <path><keyval id="release-dir"/>current-iso/</path> directory.
262 neysx 1.2 </p>
263    
264 neysx 1.1 <p>
265 nightmorph 1.10 Inside that directory you'll find ISO files. Those are full CD images which you
266 neysx 1.1 can write on a CD-R.
267     </p>
268    
269     <p>
270     In case you wonder if your downloaded file is corrupted or not, you can check
271     its MD5 checksum and compare it with the MD5 checksum we provide (such as
272 neysx 1.2 <path><keyval id="min-cd-name"/>.DIGESTS</path>). You can check the MD5
273 neysx 1.1 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
274     link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
275     </p>
276    
277     <p>
278     Another way to check the validity of the downloaded file is to use GnuPG to
279     verify the cryptographic signature that we provide (the file ending with
280 swift 1.21 <path>.asc</path>). Download the signature file and obtain the public keys:
281 neysx 1.1 </p>
282    
283     <pre caption="Obtaining the public key">
284 swift 1.22 $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 96D8BF6D 2D182910 17072058</i>
285 neysx 1.1 </pre>
286    
287     <p>
288     Now verify the signature:
289     </p>
290    
291 nightmorph 1.19 <pre caption="Verify the files">
292     <comment>(Verify the cryptographic signature)</comment>
293     $ <i>gpg --verify &lt;downloaded iso.DIGESTS.asc&gt;</i>
294     <comment>(Verify the checksum)</comment>
295     $ <i>sha1sum -c &lt;downloaded iso.DIGESTS.asc&gt;</i>
296 neysx 1.1 </pre>
297    
298     <p>
299     To burn the downloaded ISO(s), you have to select raw-burning. How you
300     do this is highly program-dependent. We will discuss <c>cdrecord</c> and
301     <c>K3B</c> here; more information can be found in our <uri
302     link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
303     </p>
304    
305     <ul>
306     <li>
307 neysx 1.11 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
308     file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's
309 neysx 1.1 device path).
310     </li>
311     <li>
312 nightmorph 1.9 With K3B, select <c>Tools</c> &gt; <c>Burn CD Image</c>. Then you can locate
313     your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
314 neysx 1.1 </li>
315     </ul>

320     <title>Booting the Installation CD</title>
321     <body>
322    
323     <p>
324 neysx 1.2 Once you have burnt your installation CD, it is time to boot it.
325 neysx 1.11 Remove all CDs from your CD drives, reboot your system and enter the BIOS.
326     This is usually done by hitting DEL, F1 or ESC, depending on your BIOS. Inside
327     the BIOS, change the boot order so that the CD-ROM is tried before the hard
328     disk. This is often found under "CMOS Setup". If you don't do this, your system
329 neysx 1.1 will just reboot from the hard disk, ignoring the CD-ROM.
330     </p>
331    
332     <p>
333 neysx 1.2 Now place the installation CD in the CD-ROM drive and reboot. You should see a
334     boot prompt. At this screen, you can hit Enter to begin the boot process with
335     the default boot options, or boot the Installation CD with custom boot options
336 swift 1.20 by specifying a kernel followed by boot options and then hitting Enter.
337 neysx 1.1 </p>
338    
339     <p>
340 swift 1.20 When the boot prompt is shown, you get the option of displaying the available
341     kernels (<c>F1</c>) and boot options (<c>F2</c>). If you make no selection
342     within 20 seconds (either displaying information or using a kernel) then the
343     LiveCD will fall back to booting from disk. This allows installations to reboot
344     and try out their installed environment without the need to remove the CD from
345     the tray (something well appreciated for remote installations).
346     </p>
347    
348     <p>
349     Now we mentioned specifying a kernel. On our Installation CDs, we provide
350     several kernels. The default one is <c>gentoo</c>. Other kernels are for
351     specific hardware needs and the <c>-nofb</c> variants which disable
352     framebuffer.
353 neysx 1.1 </p>
354    
355     <p>
356     Below you'll find a short overview on the available kernels:
357     </p>
358    
359     <table>
360     <tr>
361     <th>Kernel</th>

370 nightmorph 1.3 <ti>
371 nightmorph 1.14 Default kernel with support for K8 CPUS (including NUMA support) and EM64T
372 nightmorph 1.3 CPUs
373     </ti>
374 neysx 1.2 </tr>
375     <tr>
376 nightmorph 1.14 <ti>gentoo-nofb</ti>
377     <ti>Same as <c>gentoo</c> but without framebuffer support</ti>

381     <ti>Test your local RAM for errors</ti>
382 neysx 1.2 </tr>
383     </table>
384    
385 neysx 1.1 <p>
386     You can also provide kernel options. They represent optional settings you can
387 nightmorph 1.15 (de)activate at will.
388 neysx 1.1 </p>
389    
390 neysx 1.12 </body>

396 neysx 1.12 <body>
397 neysx 1.1
398 nightmorph 1.10 <note>
399     The CD will check for "no*" options before "do*" options, so that you can
400     override any option in the exact order you specify.
401     </note>
402    
403 neysx 1.1 <p>
404     Now boot your CD, select a kernel (if you are not happy with the default
405     <c>gentoo</c> kernel) and boot options. As an example, we show you how
406     to boot the <c>gentoo</c> kernel, with <c>dopcmcia</c> as kernel
407     parameters:
408     </p>
409    
410     <pre caption="Booting an Installation CD">
411     boot: <i>gentoo dopcmcia</i>
412     </pre>
413    
414     <p>
415 neysx 1.2 You will then be greeted with a boot screen and progress bar. If you are
416 neysx 1.1 installing Gentoo on a system with a non-US keyboard, make sure you immediately
417 neysx 1.2 press Alt-F1 to switch to verbose mode and follow the prompt. If no selection
418     is made in 10 seconds the default (US keyboard) will be accepted and the boot
419 neysx 1.1 process will continue. Once the boot process completes, you will be
420 neysx 1.2 automatically logged in to the "Live" Gentoo Linux as "root", the super user.
421     You should have a root ("#") prompt on the current console and can also switch
422     to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one
423     you started on by pressing Alt-F1.
424 neysx 1.1 </p>
425    
426     <p>
427     Now continue with <uri link="#hardware">Extra Hardware Configuration</uri>.
