60 <title>The Gentoo Installation CDs</title>
61 <subsection>
62 <title>Introduction</title>
63 <body>
64
65 <p>
66 The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
67 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
68 During the boot process your hardware is detected and the appropriate drivers
69 are loaded. They are maintained by Gentoo developers.
70 </p>
71
72 <p>
73 All Installation CDs allow you to boot, set up networking, initialize your
74 partitions and start installing Gentoo from the Internet. We currently provide
75 two Installation CDs which are equaly suitable to install Gentoo from, as long
76 as you're planning on performing an Internet-based installation using the
77 latest version of the available packages.
78 </p>
79
80 <p>
81 If you wish to install Gentoo without a working Internet connection, please use
82 the installation instructions described in the <uri
83 link="2005.1/index.xml">Gentoo 2005.1 Handbooks</uri>.
84 </p>
85
86 <p>
87 The two Installation CDs we currently provide are:
88 </p>
89
90 <ul>
91 <li>
92 The Gentoo Minimal Installation CD, a small, no-nonsense, bootable CD which
93 sole purpose is to boot the system, prepare the networking and continue
94 with the Gentoo installation.
95 </li>
96 <li>
97 The Gentoo Universal Installation CD, a bootable CD with the same abilities
98 as the Minimal Installation CD. Additionally, it contains several stage3
99 tarballs (optimized for the individual subarchitectures).
100 </li>
101 </ul>
102
103 <p>
104 To help you decide which Installation CD you need, we have written down the
105 major advantages and disadvantages of each Installation CD.

114 <p>
115 The Minimal Installation CD is called <c>install-alpha-minimal-2005.1.iso</c>
116 and takes up only 54 MB of diskspace. You can use this Installation CD to
117 install Gentoo, but always with a working Internet connection only.

145 The Universal Installation CD is called <c>install-alpha-universal-2005.1.iso</c>
146 and consumes the entire surface of a 650 MB CD. You can use this Installation CD
147 to install Gentoo, and you can even use it to install Gentoo without a working
148 internet connection, just in case you want to bring Gentoo to another PC than
149 the one you are currently installing Gentoo on :)

177
178 <p>
179 You might find a Package CD on one of our mirrors. This CD is not an
180 Installation CD but an additional resource that can be exploited during a
181 networkless installation. It contains prebuilt packages (also known as the GRP
182 set) that allow you to easily and quickly install additional applications
183 (such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless
184 Gentoo installation.
185 </p>
186
187 <p>
188 If you intend to use the Packages CD to quickly install additional software,
189 make sure that you use the same subarchitecture as the stage3 tarball you use.

195 <title>The Stage3 Tarball</title>
196 <body>
197
198 <p>
199 A stage3 tarball is an archive containing a minimal Gentoo environment, suitable
200 to continue the Gentoo installation using the instructions in this manual.
201 Previously, the Gentoo Handbook described the installation using one of three
202 stage tarballs. While Gentoo still offers stage1 and stage2 tarballs, the
203 official installation method uses the stage3 tarball. If you are interested in
204 performing a Gentoo installation using a stage1 or stage2 tarball, please read
205 the Gentoo FAQ on <uri link="/doc/en/faq.xml#stage12">How do I Install Gentoo
206 Using a Stage1 or Stage2 Tarball?</uri>

214 <title>Download, Burn and Boot a Gentoo Installation CD</title>
215 <subsection>
216 <title>Downloading and Burning the Installation CDs</title>
217 <body>
218
219 <p>
220 You have chosen to use a Gentoo Installation CD. We'll first start by
221 downloading and burning the chosen Installation CD. We previously discussed
222 the several available Installation CDs, but where can you find them?
223 </p>
224
225 <p>
226 You can download any of the Installation CDs (and, if you want to, a Packages
227 CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
228 Installation CDs are located in the <path>releases/alpha/2005.1/installcd</path>
229 directory.
230 </p>
231
232 <p>
233 Inside that directory you'll find ISO-files. Those are full CD images which you
234 can write on a CD-R.
235 </p>
236
237 <p>
238 In case you wonder if your downloaded file is corrupted or not, you can
239 check its MD5 checksum and compare it with the MD5 checksum we provide (such as
240 <path>install-alpha-minimal-2005.1.iso.md5</path>). You can check the MD5
241 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
242 link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
243 </p>
244
245 <p>
246 Another way to check the validity of the downloaded file is to use GnuPG to
247 verify the cryptographic signature that we provide (the file ending with
248 <path>.asc</path>). Download the signature file and obtain the public key:
249 </p>
250
251 <pre caption="Obtaining the public key">
252 $ <i>gpg --keyserver subkeys.pgp.net --recv-keys 17072058</i>
253 </pre>
254
255 <p>
256 Now verify the signature:
257 </p>
258
259 <pre caption="Verify the cryptographic signature">
260 $ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
261 </pre>
262
263 <p>
264 To burn the downloaded ISO(s), you have to select raw-burning. How you
265 do this is highly program-dependent. We will discuss <c>cdrecord</c> and
266 <c>K3B</c> here; more information can be found in our <uri
267 link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
268 </p>
269
270 <ul>
271 <li>
272 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
273 file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's
274 device path).
275 </li>
276 <li>
277 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
278 you can locate your ISO file within the 'Image to Burn' area. Finally click
279 <c>Start</c>.

286 <title>Booting the Installation CD</title>
287 <body>
288
289 <p>
290 When your Alpha is powered on, the first thing that gets started is the
291 firmware. It is loosely synonymous with the BIOS software on PC systems. There
292 are two types of firmware on Alpha systems: SRM (<e>Systems Reference
293 Manual</e>) and ARC (<e>Advanced Risc Console</e>).
294 </p>
295
296 <p>
297 SRM is based on the Alpha Console Subsystem specification, which provides an
298 operating environment for OpenVMS, Tru64 UNIX, and Linux operating systems. ARC
299 is based on the Advanced RISC Computing (ARC) specification, which provides
300 an operating environment for Windows NT. You can find a
301 <uri link="http://www.alphalinux.org/faq/SRM-HOWTO/">detailed guide</uri> on
302 using SRM over at the Alpha Linux website.
303 </p>
304
305 <p>
306 If your Alpha system supports both SRM and ARCs (ARC, AlphaBIOS, ARCSBIOS) you
307 should follow <uri link="http://www.alphalinux.org/faq/x31.html">these
308 instructions</uri> for switching to SRM. If your system already uses SRM, you
309 are all set. If your system can only use ARCs (Ruffian, nautilus, xl, etc.) you
310 will need to choose <c>MILO</c> later on when we are talking about bootloaders.
311 </p>
312
313 <p>
314 Now to boot an Alpha Installation CD, put the CD-ROM in the tray and reboot the
315 system. You can use SRM to boot the Installation CD. If you cannot do that, you
316 will have to use <c>MILO</c>. If you don't have <c>MILO</c> installed already,
317 use one of the precompiled <c>MILO</c> images available on <uri
318 link="http://dev.gentoo.org/~taviso/milo/">taviso's homepage</uri>.

340 You should have a root ("#") prompt on the current console and can also switch
341 to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you
342 started on by pressing Alt-F1.

354
355 <p>
356 When the Installation CD boots, it tries to detect all your hardware devices and
357 loads the appropriate kernel modules to support your hardware. In the
358 vast majority of cases, it does a very good job. However, in some cases it may
359 not auto-load the kernel
360 modules you need. If the PCI auto-detection missed some of your system's
361 hardware, you will have to load the appropriate kernel modules manually.
362 </p>
363
364 <p>
365 In the next example we try to load the <c>8139too</c> module (support for
366 certain kinds of network interfaces):
367 </p>
368

376 <title>Optional: Tweaking Hard Disk Performance</title>
377 <body>
378
379 <p>
380 If you are an advanced user, you might want to tweak the IDE hard disk
381 performance using <c>hdparm</c>. With the <c>-tT</c> options you can
382 test the performance of your disk (execute it several times to get a
383 more precise impression):
384 </p>
385
386 <pre caption="Testing disk performance">
387 # <i>hdparm -tT /dev/hda</i>
388 </pre>
389
390 <p>
391 To tweak, you can use any of the following examples (or experiment
392 yourself) which use <path>/dev/hda</path> as disk (substitute with your
393 disk):
394 </p>
395
396 <pre caption="Tweaking hard disk performance">
397 <comment>Activate DMA:</comment> # <i>hdparm -d 1 /dev/hda</i>

402 </subsection>
403 <subsection id="useraccounts">
404 <title>Optional: User Accounts</title>
405 <body>
406
407 <p>
408 If you plan on giving other people access to your installation
409 environment or you want to chat using <c>irssi</c> without root privileges (for
410 security reasons), you need to create the necessary user accounts and change
411 the root password.
412 </p>
413
414 <p>
415 To change the root password, use the <c>passwd</c> utility:
416 </p>
417
418 <pre caption="Changing the root password">
419 # <i>passwd</i>
420 New password: <comment>(Enter your new password)</comment>
421 Re-enter password: <comment>(Re-enter your password)</comment>
422 </pre>
423
424 <p>
425 To create a user account, we first enter their credentials, followed by
426 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
427 In the next example, we create a user called &quot;john&quot;.
428 </p>
429
430 <pre caption="Creating a user account">
431 # <i>useradd -m -G users john</i>
432 # <i>passwd john</i>
433 New password: <comment>(Enter john's password)</comment>
434 Re-enter password: <comment>(Re-enter john's password)</comment>
435 </pre>
436
437 <p>
438 You can change your user id from root to the newly created user by using
439 <c>su</c>:
440 </p>
441
442 <pre caption="Changing user id">
443 # <i>su - john</i>

448 <subsection>
449 <title>Optional: Viewing Documentation while Installing</title>
450 <body>
451
452 <p>
453 If you want to view the Gentoo Handbook (either from-CD or online) during the
454 installation, make sure you have created a user account (see <uri
455 link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
456 go to a new terminal and log in.
457 </p>
458
459 <p>
460 If you want to view the documentation on the CD you can immediately run
461 <c>lynx</c> to read it:
462 </p>
463
464 <pre caption="Viewing the on-CD documentation">
465 # <i>lynx /mnt/cdrom/docs/html/index.html</i>
466 </pre>
467
468 <p>
469 However, it is preferred that you use the online Gentoo Handbook as it will be
470 more recent than the one provided on the CD. You can view it using <c>lynx</c>
471 as well, but only after having completed the <e>Configuring your Network</e>
472 chapter (otherwise you won't be able to go on the Internet to view the
473 document):
474 </p>
475
476 <pre caption="Viewing the Online Documentation">
477 # <i>lynx http://www.gentoo.org/doc/en/handbook/handbook-alpha.xml</i>
478 </pre>
479
480 <p>
481 You can go back to your original terminal by pressing <c>Alt-F1</c>.

485 </subsection>
486 <subsection>
487 <title>Optional: Starting the SSH Daemon</title>
488 <body>
489
490 <p>
491 If you want to allow other users to access your computer during the
492 Gentoo installation (perhaps because those users are going to help you
493 install Gentoo, or even do it for you), you need to create a user
494 account for them and perhaps even provide them with your root password
495 (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
496 </p>
497
498 <p>
499 To fire up the SSH daemon, execute the following command:
500 </p>
501
502 <pre caption="Starting the SSH daemon">
503 # <i>/etc/init.d/sshd start</i>
504 </pre>
505
506 <p>
507 To be able to use sshd, you first need to set up your networking. Continue with
508 the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.
