85 <title>The Gentoo Universal Installation CD</title>
86 <subsection>
87 <title>Introduction</title>
88 <body>
89
90 <p>
91 Gentoo Linux can be installed using a <e>stage3</e> tarball file.
92 Such a tarball is an archive that contains a minimal environment from
93 which you can succesfully install Gentoo Linux onto your system.
94 </p>
95
96 <p>
97 Installations using a stage1 or stage2 tarball file are not documented in the
98 Gentoo Handbook - please read the <uri link="/doc/en/faq.xml#stage12">Gentoo
99 FAQ</uri> on these matters.
100 </p>

104 <subsection>
105 <title>Gentoo Universal Installation CD</title>
106 <body>
107
108 <p>
109 An Installation CD is a bootable medium which contains a self-sustained Gentoo
110 environment. It allows you to boot Linux from the CD. During the boot process
111 your hardware is detected and the appropriate drivers are loaded. The Gentoo
112 Installation CDs are maintained by Gentoo developers.
113 </p>
114
115 <p>
116 There currently are two Installation CDs available:
117 </p>
118
119 <ul>
120 <li>
121 The Universal Installation CD contains everything you need to install
122 Gentoo. It provides stage3 files for common architectures, source code
123 for the extra applications you need to choose from and, of course, the
124 installation instructions for your architecture.
125 </li>
126 <li>
127 The Minimal Installation CD contains only a minimal environment that allows
128 you to boot up and configure your network so you can connect to the
129 Internet. It does not contain any additional files and cannot be used
130 during the current installation approach.
131 </li>
132 </ul>
133
134 <p>
135 Gentoo also provides a Package CD. This is not an Installation CD but an
136 additional resource that you can exploit during the installation of your Gentoo
137 system. It contains prebuilt packages (also known as the GRP set) that allow
138 you to easily and quickly install additional applications (such as
139 OpenOffice.org, KDE, GNOME, ...) immediately after the Gentoo installation and
140 right before you update your Portage tree.
141 </p>
142
143 <p>
144 The use of the Package CD is covered later in this document.

152 <title>Download, Burn and Boot the Gentoo Universal Installation CD</title>
153 <subsection>
154 <title>Downloading and Burning the Installation CD</title>
155 <body>
156
157 <p>
158 You can download the Universal Installation CD (and, if you want to, the
159 Packages CD as well) from one of our <uri
160 link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
161 the <path><keyval id="release-dir"/>installcd</path> directory; the Package CDs
162 are located in the <path><keyval id="release-dir"/>packagecd</path> directory.
163 </p>
164
165 <p>
166 Inside those directories you'll find ISO-files. Those are full CD images which
167 you can write on a CD-R.
168 </p>
169
170 <p>
171 After downloading the file, you can verify its integrity to see if it is
172 corrupted or not:
173 </p>
174
175 <ul>
176 <li>
177 You can check its MD5 checksum and compare it with the MD5 checksum we
178 provide (for instance with the <c>md5sum</c> tool under Linux/Unix or
179 <uri link="http://www.etree.org/md5com.html">md5sum</uri> for Windows).
180 Verifying MD5 checksums with Mac OS X is described in the <uri
181 link="/doc/en/gentoo-ppc-faq.xml#doc_chap1">Gentoo PPC FAQ</uri>.
182 </li>
183 <li>
184 You can verify the cryptographic signature that we provide. You need to
185 obtain the public key we use (0x17072058) before you proceed though.
186 </li>
187 </ul>
188
189 <p>
190 To fetch our public key using the GnuPG application, run the following command:
191 </p>
192
193 <pre caption="Obtaining the public key">
194 $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 0x17072058</i>
195 </pre>
196
197 <p>
198 Now verify the signature:
199 </p>
200
201 <pre caption="Verify the cryptographic signature">
202 $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
203 </pre>
204
205 <p>
206 To burn the downloaded ISO(s), you have to select raw-burning. How you
207 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
208 <c>K3B</c> here; more information can be found in our <uri
209 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
210 </p>
211
212 <ul>
213 <li>
214 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
215 file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's device
216 path).
217 </li>
218 <li>
219 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
220 you can locate your ISO file within the 'Image to Burn' area. Finally click
221 <c>Start</c>.
222 </li>
223 </ul>

228 <title>Default: Booting the Installation CD with Yaboot</title>
229 <body>
230
231 <p>
232 On NewWorld machines place the Installation CD in the CD-ROM and reboot the
233 system. When the system-start-bell sounds, simply hold down the 'C' until the
234 CD loads.
235 </p>
236
237 <p>
238 After the Installation CD loaded, you will be greeted by a friendly welcome
239 message and a <e>boot:</e> prompt at the bottom of the screen.
240 </p>
241
242 <p>
243 We provide one generic kernel, <e>apple</e>. This kernel is built with support
244 for multiple CPUs, but it will boot on single processor machines as well.
245 </p>
246
247 <p>
248 You can tweak some kernel options at this prompt. The following table lists
249 some of the available boot options you can add:
250 </p>
251
252 <table>
253 <tr>
254 <th>Boot Option</th>
255 <th>Description</th>
256 </tr>
257 <tr>
258 <ti><c>video</c></ti>
259 <ti>
260 This option takes one of the following vendor-specific tags:
261 <c>nvidiafb</c>, <c>radeonfb</c>, <c>rivafb</c>, <c>atyfb</c>,
262 <c>aty128</c> or <c>ofonly</c>. You can follow this tag with the resolution
263 refresh rate and color depth you want to use. For instance,
264 <c>video=radeonfb:1280x1024@75-32</c> will select the ATI Radeon frame buffer
265 at a resolution of 1280x1024 with a refresh rate of 75Hz and a color depth of
266 32 bits. If you are uncertain what to choose, and the default doesn't work,
267 <c>video=ofonly</c> will most certainly work.

282 <tr>
283 <ti><c>dopcmcia</c></ti>
284 <ti>
285 If you want to use PCMCIA devices during your installation (like PCMCIA
286 network cards) you have to enable this option.
287 </ti>
288 </tr>
289 </table>
290
291 <p>
292 To use the above options, at the <e>boot:</e> prompt, type <e>apple</e> followed
293 by the desired option. In the example below, we'll force the kernel to use the
294 OpenFirmware framebuffer instead of the device specific driver.
295 </p>
296
297 <pre caption="Force the use of the OpenFirmware framebuffer">
298 boot: <i>apple video=ofonly</i>
299 </pre>
300
301 <p>
302 If you don't need to add any options, just hit enter at this prompt, and a
303 complete Gentoo Linux environment will be loaded from the CD. Continue with
304 <uri link="#booted">And When You're Booted...</uri>.

310 <title>Alternative: Booting the Installation CD on a Pegasos</title>
311 <body>
312
313 <p>
314 On the Pegasos simply insert the CD and at the SmartFirmware boot-prompt type
315 <c>boot cd /boot/menu</c>. This will open a small bootmenu where you can choose
316 between several preconfigured video configs. If you need any special boot
317 options you can append them to the command-line just like with Yaboot above.
318 For example: <c>boot cd /boot/pegasos video=radeonfb:1280x1024@75 mem=256M</c>.
319 The default kernel options (in case something goes wrong and you need it) are
320 preconfigured with <c>console=ttyS0,115200 console=tty0 init=/linuxrc
321 looptype=squashfs loop=/image.squashfs cdroot root=/dev/ram0</c>.

328 <title>Alternative: Booting the Installation CD with BootX</title>
329 <body>
330
331 <p>
332 If you have an OldWorld Mac the bootable portion of the livecd can't be used.
333 The most simple solution is to use MacOS 9 or earlier to bootstrap into a Linux
334 environment with a tool called BootX.
335 </p>
336
337 <p>
338 First, download <uri link="http://penguinppc.org/projects/bootx/">BootX</uri>
339 and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
340 archive into <c>Extensions Folder</c> and the BootX App Control Panel into
341 <c>Control Panels</c>, both of which are located in your MacOS System Folder.
342 Next, create a folder called "Linux Kernels" in your System folder and copy the
343 <c>apple</c> kernel from the CD to this folder. Finally, copy <c>apple.igz</c>
344 from the Installation CD <path>boot</path> folder into the MacOS
345 <c>System Folder</c>.
346 </p>
347
348 <p>
349 To prepare BootX, start the BootX App Control Panel. First select the Options
350 dialog and check <c>Use Specified RAM Disk</c> and select <c>apple.igz</c> from
351 your System Folder. Continue back to the initial screen and ensure that the
352 ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
353 shown below:
354 </p>
355
356 <pre caption="BootX kernel arguments">
357 cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0
358 </pre>
359
360 <note>
361 The kernel parameters in the yaboot section above are also applicable here. You
362 can append any of those options to the kernel arguments above.
363 </note>
364
365 <p>
366 Check once more to make sure the settings are correct and then save the
367 configuration. This saves typing just in case it doesn't boot or something is
368 missing. Press the Linux button at the top of the window. If everything goes
369 correctly, it should boot into the Installation CD. Continue with
370 <uri link="#booted">And When You're Booted...</uri>

380 <p>
381 You will be greeted by a root ("#") prompt on the current console. You can also
382 switch to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get
383 back to the one you started on by pressing Alt-F1. Due to the keyboard layout,
384 you may need to press Alt-fn-Fx on Apple machines.
385 </p>
386
387 <p>
388 If you are installing Gentoo on a system with a non-US keyboard, use
389 <c>loadkeys</c> to load the keymap for your keyboard. To list the available
390 keymaps, execute <c>ls /usr/share/keymaps/i386</c>. On NewWorld machines or the
391 Pegasos do not use the keymaps in <path>ppc</path> or <path>mac</path> as they
392 are for ADB-based OldWorld machines.
393 </p>
394
395 <pre caption="Listing available keymaps">

420 <p>
421 When the Installation CD boots, it tries to detect all your hardware devices and
422 loads the appropriate kernel modules to support your hardware. In the
423 vast majority of cases, it does a very good job. However, in some cases, it may
424 not auto-load the kernel modules you need. If the PCI auto-detection missed some
425 of your system's hardware, you will have to load the appropriate kernel modules
426 manually.
427 </p>
428
429 <p>
430 In the next example we try to load the <c>airport</c> module. This module
431 supports only the old Airport cards (802.11b). Airport Extreme (802.11g) is not
432 supported on the InstallCD due to restrictions on firmware distribution.
433 </p>
434
435 <pre caption="Loading the airport module">
436 # <i>modprobe airport</i>

440 On older iMacs, sometimes the network card is not detected properly. These use
441 the BMAC driver:

451 <title>Optional: Tweaking Hard Disk Performance</title>
452 <body>
453
454 <p>
455 If you are an advanced user, you might want to tweak the IDE hard disk
456 performance using <c>hdparm</c>. With the <c>-tT</c> options you can
457 test the performance of your disk (execute it several times to get a
458 more precise impression):
459 </p>
460
461 <pre caption="Testing disk performance">
462 # <i>hdparm -tT /dev/hda</i>
463 </pre>
464
465 <p>
466 To tweak, you can use any of the following examples (or experiment
467 yourself) which use <path>/dev/hda</path> as disk (substitute with your
468 disk):
469 </p>
470
471 <pre caption="Tweaking hard disk performance">

481 <title>Optional: User Accounts</title>
482 <body>
483
484 <p>
485 If you plan on giving other people access to your installation
486 environment or you want to chat using <c>irssi</c> without root privileges (for
487 security reasons), you need to create the necessary user accounts and change
488 the root password.
489 </p>
490
491 <p>
492 To change the root password, use the <c>passwd</c> utility:
493 </p>
494
495 <pre caption="Changing the root password">
496 # <i>passwd</i>
497 New password: <comment>(Enter your new password)</comment>
498 Re-enter password: <comment>(Re-enter your password)</comment>
499 </pre>
500
501 <p>
502 To create a user account, we first enter their credentials, followed by
503 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
504 In the next example, we create a user called &quot;john&quot;.
505 </p>
506
507 <pre caption="Creating a user account">

526 <title>Optional: Viewing Documentation while Installing</title>
527 <body>
528
529 <p>
530 If you want to view the Gentoo Handbook (either from-CD or online) during the
531 installation, make sure you have created a user account (see <uri
532 link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
533 go to a new terminal and log in.
534 </p>
535
536 <p>
537 If you want to view the documentation on the CD you can immediately run
538 <c>links</c> or even <c>links -g</c> for a graphical framebuffer browser to
539 read it:

547 However, it is preferred that you use the online Gentoo Handbook as it will be
548 more recent than the one provided on the CD. You can view it using <c>links</c>
549 as well, but only after having completed the <e>Configuring your Network</e>

569 If you want to allow other users to access your computer during the
570 Gentoo installation (perhaps because those users are going to help you
