17 Before we start, we first list what hardware requirements you need to
18 successfully install Gentoo on your box. This of course depends on your
19 architecture.

29 Check the following requirements before you
30 continue with the Gentoo installation:
31 </p>
32
33 <ul>
34 <li>
35 You need at least 1 Gb of free disk space
36 </li>
37 <li>
38 If you do not use prebuilt packages, you need at least 300 Mb of memory (RAM +
39 swap)
40 </li>
41 <li>
42 For the <e>SPARC architecture</e>, you should check with the <uri

57 Still interested in trying out Gentoo? Well, then it is now time to
58 choose the installation medium you want to use. Yes, you have the
59 choice, no, they are not all equal, and yes, the result is always the same: a
60 Gentoo base system.
61 </p>
62
63 <p>
64 The installation media we will describe are:
65 </p>
66
67 <ul>
68 <li>Gentoo's Minimal LiveCD</li>
69 <li>Gentoo's Universal LiveCD</li>
70 </ul>
71
72 <p>
73 Every single media has its advantages and disadvantages. We will list
74 the pros and cons of every medium so you have all the information to
75 make a justified decision. But before we continue, let's explain our
76 three-stage installation.

82 <title>The Three Stages</title>
83 <body>
84
85 <p>
86 Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
87 The one you choose depends on how much of the system you want to compile
88 yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
89 build the entire system from scratch. The <e>stage2</e> tarball is used for
90 building the entire system from a bootstrapped &quot;semi-compiled&quot; state.
91 The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
92 been built for you. As we will explain later, you can also install
93 Gentoo without compiling anything (except your kernel and some optional
94 packages). If you want this, you have to use a <e>stage3</e> tarball.
95 </p>
96
97 <p>
98 Now what stage do you have to choose?
99 </p>
100
101 <p>
102 Starting from a <e>stage1</e> allows you to have total control over the
103 optimization settings and optional build-time functionality that is
104 initially enabled on your system. This makes <e>stage1</e> installs good for
105 power users who know what they are doing. It is also a great
106 installation method for those who would like to know more about the
107 inner workings of Gentoo Linux.
108 </p>
109
110 <p>
111 A <e>stage1</e> installation can only be performed when you have a working
112 Internet connection.
113 </p>

151 </table>
152
153 <p>
154 <e>Stage2</e> installs allow you to skip the bootstrap process and doing this
155 is fine if you are happy with the optimization settings that we chose
156 for your particular <e>stage2</e> tarball.
157 </p>
158
159 <p>
160 A <e>stage2</e> installation can only be performed when you have a working
161 Internet connection.

201 <p>
202 Choosing to go with a <e>stage3</e> allows for the fastest install of Gentoo
203 Linux, but also means that your base system will have the optimization
204 settings that we chose for you (which to be honest, are good settings
205 and were carefully chosen to enhance performance while maintaining
206 stability). <e>stage3</e> is also required if you want to install Gentoo using
207 prebuilt packages or without a network connection.

234 Write down (or remember) what stage you want to use. You need this later when
235 you decide what LiveCD (or other installation medium) you want to use. You might
236 be interested to know that, if you decide to use different optimization settings
237 after having installed Gentoo, you will be able to recompile your entire system
238 with the new optimization settings.
239 </p>
240
241 <p>
242 Now take a look at the available installation media.

248 <title>Gentoo LiveCDs</title>
249 <body>
250
251 <p>
252 The <e>Gentoo LiveCDs</e> are bootable CDs which contain a
253 self-sustained Gentoo environment. They allow you to boot Linux from the CD.
254 During the boot process your hardware is detected and the appropriate drivers
255 are loaded. They are maintained by Gentoo developers.
256 </p>
257
258 <p>
259 All LiveCDs allow you to boot, setup networking, initialize your
260 partitions and start installing Gentoo from the Internet. However, some
261 LiveCDs also contain all necessary source code so you are able to install
262 Gentoo without a working network configuration.
263 </p>
264
265 <p>
266 Now what do these LiveCDs contain?

271 <subsection>
272 <title>Gentoo's Minimal LiveCD</title>
273 <body>
274
275 <p>
276 This is a small, no-nonsense, bootable CD which sole purpose is to boot the
277 system, prepare the networking and continue with the Gentoo installation. It
278 does not contain any stages (or, in some cases, a single stage1 file),
279 source code or precompiled packages. For example the sparc64 variant of this
280 LiveCD can be found in the <path>sparc64/</path> subdirectory and is called
281 <c>install-sparc64-minimal-2004.1.iso</c>.

316 <title>Gentoo's Universal LiveCD</title>
317 <body>
318
319 <p>
320 Gentoo's Universal LiveCD is a bootable CD suitable to install Gentoo without
321 networking. It contains a stage1 and stage3 tarballs (optimized for the
322 sparc architecture). For example the sparc64 variant of this CD is called
323 <c>install-sparc64-universal-2004.1.iso</c> and can be found in the
324 <path>sparc64/</path> subdirectory.
325 </p>
326
327 <p>
328 If you take a closer look into the directories you will see
329 that we provide a <e>Gentoo Package CD</e>. This CD (which isn't
330 bootable) only contains precompiled packages and can be used to install software
331 after a succesfull Gentoo Installation. To install Gentoo, you only
332 need the Universal LiveCD, but if you want OpenOffice.org, Mozilla, KDE, GNOME
333 etc. without having to compile every single one of them, you need the Packages
334 CD too. Such a Packages CD for sparc64 is called
335 <c>packages-sparc64-2004.1.iso</c>.
336 </p>
337
338 <p>
339 You only need the Packages CD if you want to perform a stage3 with GRP
340 installation.

375 <title>Download, Burn and Boot a Gentoo LiveCD</title>
376 <subsection>
377 <title>Downloading and Burning the LiveCDs</title>
378 <body>
379
380 <p>
381 You have chosen to use a Gentoo LiveCD (if not, then you are reading the
382 wrong section). We'll first start by downloading and burning the chosen
383 LiveCD. We previously discussed the several available LiveCDs, but where can you
384 find them?
385 </p>
386
387 <p>
388 Visit one of our <uri
389 link="/main/en/mirrors.xml">mirrors</uri> and go to
390 <path>releases/sparc/2004.1/livecd</path> where the LiveCD(s) of
391 your choice are located. Inside the subdirectories <path>sparc32/</path> and
392 <path>sparc64/</path> you'll find so-called ISO-files.
393 Those are full CD images which you can write on a CD-R.
394 </p>
395
396 <p>
397 In case you wonder if your downloaded file is corrupted or not, you can
398 check its MD5 checksum and compare it with the MD5 checksum we provide (such as
399 <path>install-sparc64-minimal-2004.1.iso.md5</path>). You can check the MD5
400 checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
401 link="http://www.md5summer.org">md5summer</uri> for Windows.
402 </p>
403
404 <p>
405 To burn the downloaded ISO(s), you have to select raw-burning. How you
406 do this is highly program-dependent. We will discuss a couple of popular
407 tools on how to do this.
408 </p>
409
410 <ul>
411 <li>
412 With EasyCD Creator you select <c>File</c>, <c>Record CD
413 from CD image</c>. Then you change the <c>Files of type</c> to <c>ISO image
414 file</c>. Then locate the ISO file and click <c>Open</c>. When you click on
415 <c>Start recording</c> the ISO image will be burned correctly onto the CD-R.
416 </li>
417 <li>
418 With Nero Burning ROM, select <c>File</c>, <c>Burn CD image</c>. Set the
419 type of file to <c>*.*</c> and select the ISO file. Older versions of Nero
420 will tell you they don't recognize the format -- confirm here, it does
421 recognize it but doesn't know it yet :) In the next dialog, set the
422 following parameters:
423 <ul>
424 <li>Type of image: <c>Data Mode 1</c></li>
425 <li>Block size: <c>2048 bytes</c></li>
426 <li>File precursor and length of the image trailer: <c>0 bytes</c></li>
427 <li>Scrambled: <c>no</c></li>
428 <li>Swapped: <c>no</c></li>
429 </ul>
430 Now click on <c>OK</c> and then <c>Burn</c> (the CD-R)
431 </li>
432 <li>
433 With cdrecord, you simply type <c>cdrecord dev=/dev/hdc</c> (replace
434 <path>/dev/hdc</path> with your CD-RW drive's device path) followed
435 by the path to the ISO file :)
436 </li>
437 <li>
438 With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
439 you can locate your ISO file within the 'Image to Burn' area. Finally click
440 <c>Start</c>.
441 </li>
442 </ul>
443

446 <subsection>
447 <title>Booting the SPARC LiveCD</title>
448 <body>
449
450 <p>
451 Insert the Gentoo LiveCD in the CD-ROM and boot your system. During startup,
452 press Stop-A to enter OpenBootPROM (OBP). Once you are in the OBP, boot from the
453 CD-ROM:
454 </p>
455
456 <pre caption="Booting the LiveCD">
457 ok <i>boot cdrom</i>
458 </pre>
459
460 <p>
461 You will be greeted by the SILO boot manager (on the LiveCD). Type in
462 <c>gentoo-2.4</c> (single-CPU kernel) or <c>gentoo-2.4-smp</c>
463 (multi-CPU kernel) and press enter to continue booting the system. In the
464 following example we'll boot the <c>gentoo-2.4</c> kernel.
465 </p>
466
467 <pre caption="Continue booting from the LiveCD">
468 boot: <i>gentoo-2.4</i>
469 </pre>
470
471 <p>
472 Once the LiveCD is booted, you will be greeted by a login prompt. Log on as
473 <c>root</c>. There is no password, so when you are asked for one, press Enter.
474 </p>
475
476 <pre caption="Logging on onto the LiveCD">
477 login: <i>root</i>
478 password: <comment>(Press Enter here)</comment>
479 </pre>
480
481 <p>
482 You should have a root ("#") prompt on the current console and can also switch
483 to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you
484 started on by pressing Alt-F1.
485 </p>
486

498 If not all hardware is supported out-of-the-box, you will need to load the
499 appropriate kernel modules.
500 </p>
501
502 <p>
503 In the next example we try to load the <c>8139too</c> module (support for
504 certain kinds of network interfaces):

514 <title>Optional: Tweaking Hard Disk Performance</title>
515 <body>
516
517 <p>
518 If you are an advanced user, you might want to tweak the IDE hard disk
519 performance using <c>hdparm</c>. With the <c>-tT</c> options you can
520 test the performance of your disk (execute it several times to get a
521 more precise impression):
522 </p>
523
524 <pre caption="Testing disk performance">
525 # <i>hdparm -tT /dev/hda</i>
526 </pre>
527
528 <p>
529 To tweak, you can use any of the following examples (or experiment
530 yourself) which use <path>/dev/hda</path> as disk (substitute with your
531 disk):
532 </p>
533
534 <pre caption="Tweaking hard disk performance">
535 <comment>Activate DMA:</comment> # <i>hdparm -d 1 /dev/hda</i>

542 <title>Optional: User Accounts</title>
543 <body>
544
545 <p>
546 If you plan on giving other people access to your installation
547 environment or you want to chat using <c>irssi</c> without root privileges (for
548 security reasons), you need to create the necessary user accounts and change
549 the root password.
550 </p>
551
552 <p>
553 To change the root password, use the <c>passwd</c> utility:
554 </p>
555
556 <pre caption="Changing the root password">
557 # <i>passwd</i>
558 New password: <comment>(Enter your new password)</comment>
559 Re-enter password: <comment>(Re-enter your password)</comment>
560 </pre>
561
562 <p>
563 To create a user account, we first enter their credentials, followed by
564 its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
565 In the next example, we create a user called &quot;john&quot;.
566 </p>
567
568 <pre caption="Creating a user account">
569 # <i>useradd john</i>
570 # <i>passwd john</i>

572 Re-enter password: <comment>(Re-enter john's password)</comment>
573 </pre>
574
575 <p>
576 You can change your user id from root to the newly created user by using
577 <c>su</c>:

587 <title>Optional: Starting the SSH Daemon</title>
588 <body>
589
590 <p>
591 If you want to allow other users to access your computer during the
592 Gentoo installation (perhaps because those users are going to help you
593 install Gentoo, or even do it for you), you need to create a user
594 account for them and perhaps even provide them with your root password
595 (<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
596 </p>
597
598 <p>
599 To fire up the SSH daemon, execute the following command:
600 </p>
601
602 <pre caption="Starting the SSH daemon">
603 # <i>/etc/init.d/sshd start</i>
604 </pre>
605
