85 <title>The Gentoo Installation CDs</title>
86 <subsection>
87 <title>Introduction</title>
88 <body>
89
90 <p>
91 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
92 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
93 During the boot process your hardware is detected and the appropriate drivers
94 are loaded. They are maintained by Gentoo developers.
95 </p>
96
97 <p>
98 All Installation CDs allow you to boot, set up networking, initialize your
99 partitions and start installing Gentoo from the Internet.
100 </p>
101
102 <!--
103 <impo>
104 If you wish to install Gentoo without a working Internet connection, or would
105 like to use one of the provided installers, please use the installation
106 instructions described in the <uri link="2008.0/">Gentoo 2008.0
107 Handbooks</uri>.
108 </impo>
109 -->
110 <!--
111 <p>
112 The Installation CDs that we currently provide are:
113 </p>
114
115 <ul>
116 <li>
117 The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable
118 CD which sole purpose is to boot the system, prepare the networking and
119 continue with the Gentoo installation.
120 </li>
121 <li>
122 The Universal Installation CD contains everything you need to install
123 Gentoo. It provides stage3 files for common architectures, source code
124 for the extra applications you need to choose from and, of course, the
125 installation instructions for your architecture.
126 </li>
127 </ul>
128
129 <p>
130 Gentoo also provides a Package CD. This is not an Installation CD but an
131 additional resource that you can exploit during the installation of your Gentoo
132 system. It contains prebuilt packages (also known as the GRP set) that allow
133 you to easily and quickly install additional applications (such as
134 OpenOffice.org, KDE, GNOME, ...) immediately after the Gentoo installation and
135 right before you update your Portage tree.
136 </p>
137
138 <p>
139 The use of the Package CD is covered later in this document.

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

178
179 <p>
180 A stage3 tarball is an archive containing a minimal Gentoo environment,
181 suitable to continue the Gentoo installation using the instructions in this
182 manual. Previously, the Gentoo Handbook described the installation using one of
183 three stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
184 official installation method uses the stage3 tarball. If you are interested in
185 performing a Gentoo installation using a stage1 or stage2 tarball, please read
186 the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo
187 Using a Stage1 or Stage2 Tarball?</uri>
188 </p>
189

191 Stage3 tarballs can be downloaded from <path><keyval
192 id="release-dir"/>current-stage3/</path> on any of the <uri

204 <title>Download, Burn and Boot a Gentoo Installation CD</title>
205 <subsection>
206 <title>Downloading and Burning the Installation CDs</title>
207 <body>
208
209 <p>
210 You have chosen to use a Gentoo Installation CD. We'll first start by
211 downloading and burning the chosen Installation CD. We previously discussed
212 the several available Installation CDs, but where can you find them?
213 </p>
214
215 <p>
216 You can download any of the Installation CDs from one of our <uri
217 link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
218 the <path><keyval id="release-dir"/>current-iso/</path> directory.
219 </p>
220
221 <p>
222 Inside that directory you'll find ISO files. Those are full CD images which you
223 can write on a CD-R.
224 </p>
225
226 <p>
227 In case you wonder if your downloaded file is corrupted or not, you can check
228 its MD5 checksum and compare it with the MD5 checksum we provide (such as
229 <path><keyval id="min-cd-name"/>.DIGESTS</path>). You can check the MD5
230 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
231 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
232 </p>
233
234 <p>
235 Another way to check the validity of the downloaded file is to use GnuPG to
236 verify the cryptographic signature that we provide (the file ending with
237 <path>.asc</path>). Download the signature file and obtain the public key:
238 </p>
239
240 <pre caption="Obtaining the public key">
241 $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 2D182910</i>
242 </pre>
243
244 <p>
245 Now verify the signature:
246 </p>
247
248 <pre caption="Verify the files">
249 <comment>(Verify the cryptographic signature)</comment>
250 $ <i>gpg --verify &lt;downloaded iso.DIGESTS.asc&gt;</i>
251 <comment>(Verify the checksum)</comment>
252 $ <i>sha1sum -c &lt;downloaded iso.DIGESTS.asc&gt;</i>
253 </pre>
254
255 <p>
256 To burn the downloaded ISO(s), you have to select raw-burning. How you
257 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
258 <c>K3B</c> here; more information can be found in our <uri
259 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
260 </p>
261
262 <ul>
263 <li>
264 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
265 file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's device
266 path).
267 </li>
268 <li>
269 With K3B, select <c>Tools</c> &gt; <c>Burn CD Image</c>. Then you can locate
270 your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
271 </li>
272 </ul>

277 <title>Default: Booting the Installation CD with Yaboot</title>
278 <body>
279
280 <p>
281 On NewWorld machines place the Installation CD in the CD-ROM and reboot the
282 system. When the system-start-bell sounds, simply hold down the 'C' until the
283 CD loads.
284 </p>
285
286 <p>
287 After the Installation CD loaded, you will be greeted by a friendly welcome
288 message and a <e>boot:</e> prompt at the bottom of the screen.
289 </p>
290
291 <p>
292 We provide one generic kernel, <e>apple</e>. This kernel is built with support
293 for multiple CPUs, but it will boot on single processor machines as well.
294 </p>
295
296 <p>
297 You can tweak some kernel options at this prompt. The following table lists
298 some of the available boot options you can add:
299 </p>
300
301 <table>
302 <tr>
303 <th>Boot Option</th>
304 <th>Description</th>
305 </tr>
306 <tr>
307 <ti><c>video</c></ti>
308 <ti>
309 This option takes one of the following vendor-specific tags:
310 <c>nvidiafb</c>, <c>radeonfb</c>, <c>rivafb</c>, <c>atyfb</c>,
311 <c>aty128</c> or <c>ofonly</c>. You can follow this tag with the resolution
312 refresh rate and color depth you want to use. For instance,
313 <c>video=radeonfb:1280x1024@75-32</c> will select the ATI Radeon frame buffer
314 at a resolution of 1280x1024 with a refresh rate of 75Hz and a color depth of
315 32 bits. If you are uncertain what to choose, and the default doesn't work,
316 <c>video=ofonly</c> will most certainly work.

332 <ti><c>dopcmcia</c></ti>
333 <ti>
334 If you want to use PCMCIA devices during your installation (like PCMCIA
335 network cards) you have to enable this option.
336 </ti>
337 </tr>
338 <tr>
339 <ti><c>dosshd</c></ti>
340 <ti>Starts <c>sshd</c>. Useful for unattended installs.</ti>
341 </tr>
342 <tr>
343 <ti><c>passwd=foo</c></ti>
344 <ti>
345 Sets whatever is after the = as the root password. Use with <c>dosshd</c>
346 for remote installs.
347 </ti>
348 </tr>
349 </table>
350
351 <p>
352 To use the above options, at the <e>boot:</e> prompt, type <e>apple</e> followed
353 by the desired option. In the example below, we'll force the kernel to use the
354 Open Firmware framebuffer instead of the device specific driver.
355 </p>
356
357 <pre caption="Force the use of the Open Firmware framebuffer">
358 boot: <i>apple video=ofonly</i>
359 </pre>
360
361 <p>
362 If you don't need to add any options, just hit enter at this prompt, and a
363 complete Gentoo Linux environment will be loaded from the CD. Continue with
364 <uri link="#booted">And When You're Booted...</uri>.

370 <title>Alternative: Booting the Installation CD on a Pegasos</title>
371 <body>
372
373 <p>
374 On the Pegasos simply insert the CD and at the SmartFirmware boot-prompt type
375 <c>boot cd /boot/menu</c>. This will open a small bootmenu where you can choose
376 between several preconfigured video configs. If you need any special boot
377 options you can append them to the command-line just like with Yaboot above.
378 For example: <c>boot cd /boot/pegasos video=radeonfb:1280x1024@75 mem=256M</c>.
379 The default kernel options (in case something goes wrong and you need it) are
380 preconfigured with <c>console=ttyS0,115200 console=tty0 init=/linuxrc
381 looptype=squashfs loop=/image.squashfs cdroot root=/dev/ram0</c>.

388 <title>Alternative: Booting the Installation CD with BootX</title>
389 <body>
390
391 <p>
392 If you have an OldWorld Mac the bootable portion of the livecd can't be used.
393 The most simple solution is to use MacOS 9 or earlier to bootstrap into a Linux
394 environment with a tool called BootX.
395 </p>
396
397 <p>
398 First, download <uri link="http://penguinppc.org/bootloaders/bootx/">BootX</uri>
399 and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
400 archive into <c>Extensions Folder</c> and the BootX App Control Panel into
401 <c>Control Panels</c>, both of which are located in your MacOS System Folder.
402 Next, create a folder called "Linux Kernels" in your System folder and copy the
403 <c>apple</c> kernel from the CD to this folder. Finally, copy <c>apple.igz</c>
404 from the Installation CD <path>boot</path> folder into the MacOS
405 <c>System Folder</c>.
406 </p>
407
408 <p>
409 To prepare BootX, start the BootX App Control Panel. First select the Options
410 dialog and check <c>Use Specified RAM Disk</c> and select <c>apple.igz</c> from
411 your System Folder. Continue back to the initial screen and ensure that the
412 ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
413 shown below:
414 </p>
415
416 <pre caption="BootX kernel arguments">
417 cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0
418 </pre>
419
420 <note>
421 The kernel parameters in the yaboot section above are also applicable here. You
422 can append any of those options to the kernel arguments above.
423 </note>
424
425 <p>
426 Check once more to make sure the settings are correct and then save the
427 configuration. This saves typing just in case it doesn't boot or something is
428 missing. Press the Linux button at the top of the window. If everything goes
429 correctly, it should boot into the Installation CD. Continue with
430 <uri link="#booted">And When You're Booted...</uri>
431 </p>

436 <subsection id="booted">
437 <title>And When You're Booted...</title>

440 <p>
441 You will be greeted by a root ("#") prompt on the current console. You can also
442 switch to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get
443 back to the one you started on by pressing Alt-F1. Due to the keyboard layout,
444 you may need to press Alt-fn-Fx on Apple machines.
445 </p>
446
447 <p>
448 If you are installing Gentoo on a system with a non-US keyboard, use
449 <c>loadkeys</c> to load the keymap for your keyboard. To list the available
450 keymaps, execute <c>ls /usr/share/keymaps/i386</c>.
