110     <p>
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.

192     Every 6 months (give or take), a special DVD is crafted by the Gentoo Ten
193     project which can be used to install Gentoo with too. The instructions further
194     down this chapter target the Minimal Installation CDs so might be a bit
195     different. However, the LiveDVD (or any other bootable
196     Linux environment) supports getting a root prompt by just invoking <c>sudo
197     su -</c> or <c>sudo -i</c> on a terminal.

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

263     <subsection>
264     <title>Downloading and Burning the Installation CDs</title>
265     <body>
266    
267     <p>
268 neysx 1.11 You have chosen to use a Gentoo Installation CD. We'll first start by
269     downloading and burning the chosen Installation CD. We previously discussed
270     the several available Installation CDs, but where can you find them?
271 neysx 1.1 </p>
272    
273 nightmorph 1.3 <p>
274 neysx 1.2 You can download any of the Installation CDs from one of our <uri
275     link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
276 nightmorph 1.17 the <path><keyval id="release-dir"/>current-iso/</path> directory.
277 neysx 1.2 </p>
278    
279 neysx 1.1 <p>
280 nightmorph 1.10 Inside that directory you'll find ISO files. Those are full CD images which you
281 neysx 1.1 can write on a CD-R.
282     </p>
283    
284     <p>
285     In case you wonder if your downloaded file is corrupted or not, you can check
286     its MD5 checksum and compare it with the MD5 checksum we provide (such as
287 neysx 1.2 <path><keyval id="min-cd-name"/>.DIGESTS</path>). You can check the MD5
288 neysx 1.1 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
289     link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
290     </p>
291    
292     <p>
293     Another way to check the validity of the downloaded file is to use GnuPG to
294     verify the cryptographic signature that we provide (the file ending with
295 swift 1.25 <path>.asc</path>). Download the signature file and obtain the public keys whose
296     key ids can be found on the <uri link="/proj/en/releng/index.xml">release
297     engineering project site</uri>.
298 neysx 1.1 </p>
299    
300     <pre caption="Obtaining the public key">
301 swift 1.25 <comment>(... Substitute the key ids with those mentioned on the release engineering site ...)</comment>
302 swift 1.22 $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 96D8BF6D 2D182910 17072058</i>
303 neysx 1.1 </pre>
304    
305     <p>
306     Now verify the signature:
307     </p>
308    
309 nightmorph 1.19 <pre caption="Verify the files">
310     <comment>(Verify the cryptographic signature)</comment>
311     $ <i>gpg --verify &lt;downloaded iso.DIGESTS.asc&gt;</i>
312     <comment>(Verify the checksum)</comment>
313     $ <i>sha1sum -c &lt;downloaded iso.DIGESTS.asc&gt;</i>
314 neysx 1.1 </pre>
315    
316     <p>
317     To burn the downloaded ISO(s), you have to select raw-burning. How you
318     do this is highly program-dependent. We will discuss <c>cdrecord</c> and
319     <c>K3B</c> here; more information can be found in our <uri
320     link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
321     </p>
322    
323     <ul>
324     <li>
325 neysx 1.11 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
326     file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's
327 neysx 1.1 device path).
328     </li>
329     <li>
330 nightmorph 1.9 With K3B, select <c>Tools</c> &gt; <c>Burn CD Image</c>. Then you can locate
331     your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
332 neysx 1.1 </li>

337     <subsection>
338     <title>Booting the Installation CD</title>
339     <body>
340    
341     <p>
342 neysx 1.2 Once you have burnt your installation CD, it is time to boot it.
343 neysx 1.11 Remove all CDs from your CD drives, reboot your system and enter the BIOS.
344     This is usually done by hitting DEL, F1 or ESC, depending on your BIOS. Inside
345     the BIOS, change the boot order so that the CD-ROM is tried before the hard
346     disk. This is often found under "CMOS Setup". If you don't do this, your system
347 neysx 1.1 will just reboot from the hard disk, ignoring the CD-ROM.
348     </p>
349    
350     <p>
351 neysx 1.2 Now place the installation CD in the CD-ROM drive and reboot. You should see a
352     boot prompt. At this screen, you can hit Enter to begin the boot process with
353     the default boot options, or boot the Installation CD with custom boot options
354 swift 1.20 by specifying a kernel followed by boot options and then hitting Enter.
355 neysx 1.1 </p>
356    
357     <p>
358 swift 1.20 When the boot prompt is shown, you get the option of displaying the available
359     kernels (<c>F1</c>) and boot options (<c>F2</c>). If you make no selection
360     within 20 seconds (either displaying information or using a kernel) then the
361     LiveCD will fall back to booting from disk. This allows installations to reboot
362     and try out their installed environment without the need to remove the CD from
363     the tray (something well appreciated for remote installations).
364     </p>
365    
366     <p>
367     Now we mentioned specifying a kernel. On our Installation CDs, we provide
368     several kernels. The default one is <c>gentoo</c>. Other kernels are for
369     specific hardware needs and the <c>-nofb</c> variants which disable
370     framebuffer.
371 neysx 1.1 </p>
372    
373     <p>
374     Below you'll find a short overview on the available kernels:
375     </p>
376    
377     <table>
378     <tr>
379     <th>Kernel</th>

388 nightmorph 1.3 <ti>
389 nightmorph 1.14 Default kernel with support for K8 CPUS (including NUMA support) and EM64T
390 nightmorph 1.3 CPUs
391     </ti>
392 neysx 1.2 </tr>
393     <tr>
394 nightmorph 1.14 <ti>gentoo-nofb</ti>
395     <ti>Same as <c>gentoo</c> but without framebuffer support</ti>

399     <ti>Test your local RAM for errors</ti>
400 neysx 1.2 </tr>
401     </table>
402    
403 neysx 1.1 <p>
404     You can also provide kernel options. They represent optional settings you can
405 nightmorph 1.15 (de)activate at will.
406 neysx 1.1 </p>
407    
408 neysx 1.12 </body>

414 neysx 1.12 <body>
415 neysx 1.1
416 nightmorph 1.10 <note>
417     The CD will check for "no*" options before "do*" options, so that you can
418     override any option in the exact order you specify.
419     </note>
420    
421 neysx 1.1 <p>
422     Now boot your CD, select a kernel (if you are not happy with the default
423     <c>gentoo</c> kernel) and boot options. As an example, we show you how
424     to boot the <c>gentoo</c> kernel, with <c>dopcmcia</c> as kernel
425     parameters:
426     </p>
427    
428     <pre caption="Booting an Installation CD">
429     boot: <i>gentoo dopcmcia</i>
430     </pre>
431    
432     <p>
433 neysx 1.2 You will then be greeted with a boot screen and progress bar. If you are
434 neysx 1.1 installing Gentoo on a system with a non-US keyboard, make sure you immediately
435 neysx 1.2 press Alt-F1 to switch to verbose mode and follow the prompt. If no selection
436     is made in 10 seconds the default (US keyboard) will be accepted and the boot
437 neysx 1.1 process will continue. Once the boot process completes, you will be
438 neysx 1.2 automatically logged in to the "Live" Gentoo Linux as "root", the super user.
439     You should have a root ("#") prompt on the current console and can also switch
440     to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one
441     you started on by pressing Alt-F1.
442 neysx 1.1 </p>
