<title>The Gentoo Installation CDs</title>
<subsection>
<title>Introduction</title>
<body>

<p>
The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
self-sustained Gentoo environment. They allow you to boot Linux from the CD.
During the boot process your hardware is detected and the appropriate drivers
are loaded. They are maintained by Gentoo developers.
</p>

<p>
All Installation CDs allow you to boot, set up networking, initialize your
partitions and start installing Gentoo from the Internet. We currently provide
two Installation CDs which are equaly suitable to install Gentoo from, as long 
as you're planning on performing an Internet-based installation using the latest
version of the available packages.
</p>

<p>
If you wish to install Gentoo without a working Internet connection, please use
the installation instructions described in the <uri
link="2005.1/index.xml">Gentoo 2005.1 Handbooks</uri>.
</p>

<p>
The two Installation CDs that we currently provide are:
</p>

<ul>
  <li>
    The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable CD
    which sole purpose is to boot the system, prepare the networking and 
    continue with the Gentoo installation.
  </li>
  <li>
    The Gentoo <e>Universal</e> Installation CD, a bootable CD with the same 
    abilities as the Minimal Installation CD. Additionally, it contains 
    several stage3 tarballs (optimized for the individual subarchitectures). 
  </li>
</ul>

<p>
We currently only provide Installation CDs for the sparc64 architecture. Users
of sparc32 can use the experimental netboot images to install Gentoo from.
More information about netbooting can be found in our <uri
link="/doc/en/gentoo-sparc-netboot-howto.xml">Gentoo/SPARC Netboot
HOWTO</uri>.
</p>

<p>
To help you decide which Installation CD you need, we have written down the
major advantages and disadvantages of each Installation CD.
</p>

</body>
</subsection>
<subsection>
<title>Gentoo's Minimal Installation CD</title>
<body>

<p>
The Minimal Installation CD is called <c>install-sparc64-minimal-2005.1.iso</c> 
and takes up only 130 MB of diskspace. You can use this Installation CD to 
install Gentoo, but always with a working Internet connection only.
</p>

<table>
<tr>
  <th>Minimal Installation CD</th>
  <th>Pros and Cons</th>
</tr>
<tr>
  <th>+</th>
  <ti>Smallest download</ti>
</tr>
<tr>
  <th>-</th>
  <ti>
    Contains no stage3 tarball, no Portage snapshot, no prebuilt packages and is
    therefore not suitable for networkless installation
  </ti>
</tr>
</table>

</body>
</subsection>
<subsection>
<title>Gentoo's Universal Installation CD</title>
<body>

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

<table>
<tr>
  <th>Universal Installation CD</th>
  <th>Pros and Cons</th>
</tr>
<tr>
  <th>+</th>
  <ti>
    Contains everything you need. You can even install without a network
    connection.
  </ti>
</tr>
<tr>
  <th>-</th>
  <ti>Huge download</ti>
</tr>
</table>

</body>
</subsection>
<subsection>
<title>Other CDs</title>
<body>

<p>
You might find a <e>Package CD</e> on one of our mirrors. This CD is not an
Installation CD but an additional resource that can be exploited during a
networkless installation. It contains prebuilt packages (also known as the GRP
set) that allow you to easily and quickly install additional applications
(such as OpenOffice.org, KDE, GNOME, ...) immediately after the networkless
Gentoo installation.
</p>

<p>
If you intend to use the Packages CD to quickly install additional software,
make sure that you use the same subarchitecture as the stage3 tarball you use.
</p>

</body>
</subsection>
<subsection>
<title>The Stage3 Tarball</title>
<body>

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

<title>Download, Burn and Boot a Gentoo Installation CD</title>
<subsection>
<title>Downloading and Burning the Installation CDs</title>
<body>

<p>
You have chosen to use a Gentoo Installation CD. We'll first start by 
downloading and burning the chosen Installation CD. We previously discussed 
the several available Installation CDs, but where can you find them?
</p>

<p>
You can download any of the Installation CDs (and, if you want to, a Packages 
CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
Installation CDs are located in the 
<path>releases/sparc/2005.1/sparc64/installcd</path> directory.
</p>

<p>
Inside that directory you'll find ISO-files. Those are full CD images which you
can write on a CD-R.
</p>

<p>
In case you wonder if your downloaded file is corrupted or not, you can check its
MD5 checksum and compare it with the MD5 checksum we provide (such as
<path>install-sparc64-minimal-2005.1.iso.md5</path>). You can check the MD5 
checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
</p>

<p>
Another way to check the validity of the downloaded file is to use GnuPG to
verify the cryptographic signature that we provide (the file ending with
<path>.asc</path>). Download the signature file and obtain the public key:
</p>

<pre caption="Obtaining the public key">
$ <i>gpg --keyserver pgp.mit.edu --recv-keys 17072058</i>
</pre>

<p>
Now verify the signature:
</p>

<pre caption="Verify the cryptographic signature">
$ <i>gpg --verify &lt;signature file&gt; &lt;downloaded iso&gt;</i>
</pre>

<p>
To burn the downloaded ISO(s), you have to select raw-burning. How you
do this is highly program-dependent. We will discuss <c>cdrecord</c> and
<c>K3B</c> here; more information can be found in our <uri
link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
</p>

<ul>
  <li>
    With cdrecord, you simply type <c>cdrecord dev=/dev/hdc &lt;downloaded iso
    file&gt;</c> (replace <path>/dev/hdc</path> with your CD-RW drive's device 
    path).
  </li>
  <li>
    With K3B, select <c>Tools</c> &gt; <c>CD</c> &gt; <c>Burn Image</c>. Then
    you can locate your ISO file within the 'Image to Burn' area. Finally click
    <c>Start</c>.
  </li>
</ul>

</body>
</subsection>
<subsection>
<title>Booting the Installation CD</title>
<body>

<p>
Insert the Gentoo Installation CD in the CD-ROM and boot your system. During 
startup, press Stop-A to enter OpenBootPROM (OBP). Once you are in the OBP, 
boot from the CD-ROM:
</p>

<pre caption="Booting the Installation CD">
ok <i>boot cdrom</i>
</pre>

<p>
You will be greeted by the SILO boot manager (on the Installation CD). Type in
<c>gentoo-2.4</c> and press enter to continue booting the 
system:
</p>

<pre caption="Continue booting from the Installation CD">
boot: <i>gentoo-2.4</i>
</pre>

<p>
Once the Installation CD is booted, you will be automatically logged on to the
system.
</p>

<p>
You should have a root ("#") prompt on the current console and can also switch
to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you
started on by pressing Alt-F1.  You will also find a root prompt on the serial
console (<path>ttyS0</path>).
</p>

<p>
Continue with <uri link="#hardware">Extra Hardware Configuration</uri>.
</p>

</body>
</subsection>
<subsection id="hardware">
<title>Extra Hardware Configuration</title>
<body>

<p>
If not all hardware is supported out-of-the-box, you will need to load the
appropriate kernel modules.
</p>

<p>
In the next example we try to load the <c>8139too</c> module (support for 
certain kinds of network interfaces):
</p>

<pre caption="Loading kernel modules">
# <i>modprobe 8139too</i>
</pre>

</body>
</subsection>
<subsection id="useraccounts">
<title>Optional: User Accounts</title>
<body>

<p>
If you plan on giving other people access to your installation
environment or you want to chat using <c>irssi</c> without root privileges (for
security reasons), you need to create the necessary user accounts and change 
the root password.
</p>

<p>
To change the root password, use the <c>passwd</c> utility:
</p>

<pre caption="Changing the root password">
# <i>passwd</i>
New password: <comment>(Enter your new password)</comment>
Re-enter password: <comment>(Re-enter your password)</comment>
</pre>

<p>
To create a user account, we first enter their credentials, followed by
its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
In the next example, we create a user called &quot;john&quot;.
</p>

<pre caption="Creating a user account">
# <i>useradd -m -G users john</i>
# <i>passwd john</i>
New password: <comment>(Enter john's password)</comment>
Re-enter password: <comment>(Re-enter john's password)</comment>
</pre>

<p>
You can change your user id from root to the newly created user by using
<c>su</c>:
</p>

<pre caption="Changing user id">
# <i>su - john</i>
</pre>

</body>
</subsection>
<subsection>
<title>Optional: Viewing Documentation while Installing</title>
<body>

<p>
If you want to view the Gentoo Handbook (either from-CD or online) during the
installation, make sure you have created a user account (see <uri
link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
go to a new terminal and log in.
</p>

<p>
If you want to view the documentation on the CD you can immediately run
<c>links2</c> to read it:
</p>

<pre caption="Viewing the on-CD documentation">
# <i>links2 /mnt/cdrom/docs/handbook/html/index.html</i>
</pre>

<p>
However, it is preferred that you use the online Gentoo Handbook as it will be
more recent than the one provided on the CD. You can view it using <c>links2</c>
as well, but only after having completed the <e>Configuring your Network</e>
chapter (otherwise you won't be able to go on the Internet to view the
document):
</p>

<pre caption="Viewing the Online Documentation">
# <i>links2 http://www.gentoo.org/doc/en/handbook/handbook-sparc.xml</i>
</pre>

<p>
You can go back to your original terminal by pressing <c>Alt-F1</c>.
</p>

</body>
</subsection>
<subsection>
<title>Optional: Starting the SSH Daemon</title>
<body>

<p>
If you want to allow other users to access your computer during the
Gentoo installation (perhaps because those users are going to help you
install Gentoo, or even do it for you), you need to create a user
account for them and perhaps even provide them with your root password 
(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
</p>

<p>
To fire up the SSH daemon, execute the following command:
</p>

<pre caption="Starting the SSH daemon">
# <i>/etc/init.d/sshd start</i>
</pre>

<p>
To be able to use sshd, you first need to set up your networking. Continue with
the chapter on <uri link="?part=1&amp;chap=3">Configuring your Network</uri>.

278	do this is highly program-dependent. We will discuss <c>cdrecord</c> and
279	<c>K3B</c> here; more information can be found in our <uri
280	link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
281	</p>
282
283	<ul>
284	<li>
285	With cdrecord, you simply type <c>cdrecord dev=/dev/hdc <downloaded iso
286	file></c> (replace <path>/dev/hdc</path> with your CD-RW drive's device
287	path).
288	</li>
289	<li>
290	With K3B, select <c>Tools</c> > <c>CD</c> > <c>Burn Image</c>. Then
291	you can locate your ISO file within the 'Image to Burn' area. Finally click
292	<c>Start</c>.

299	<title>Booting the Installation CD</title>
300	<body>
301
302	<p>
303	Insert the Gentoo Installation CD in the CD-ROM and boot your system. During
304	startup, press Stop-A to enter OpenBootPROM (OBP). Once you are in the OBP,
305	boot from the CD-ROM:
306	</p>
307
308	<pre caption="Booting the Installation CD">
309	ok <i>boot cdrom</i>
310	</pre>
311
312	<p>
313	You will be greeted by the SILO boot manager (on the Installation CD). Type in
314	<c>gentoo-2.4</c> and press enter to continue booting the
315	system:
316	</p>
317
318	<pre caption="Continue booting from the Installation CD">
319	boot: <i>gentoo-2.4</i>
320	</pre>
321
322	<p>
323	Once the Installation CD is booted, you will be automatically logged on to the
324	system.
325	</p>
326
327	<p>
328	You should have a root ("#") prompt on the current console and can also switch
329	to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get back to the one you
330	started on by pressing Alt-F1. You will also find a root prompt on the serial
331	console (<path>ttyS0</path>).

345	If not all hardware is supported out-of-the-box, you will need to load the
346	appropriate kernel modules.
347	</p>
348
349	<p>
350	In the next example we try to load the <c>8139too</c> module (support for
351	certain kinds of network interfaces):

361	<title>Optional: User Accounts</title>
362	<body>
363
364	<p>
365	If you plan on giving other people access to your installation
366	environment or you want to chat using <c>irssi</c> without root privileges (for
367	security reasons), you need to create the necessary user accounts and change
368	the root password.
369	</p>
370
371	<p>
372	To change the root password, use the <c>passwd</c> utility:
373	</p>
374
375	<pre caption="Changing the root password">
376	# <i>passwd</i>
377	New password: <comment>(Enter your new password)</comment>
378	Re-enter password: <comment>(Re-enter your password)</comment>
379	</pre>
380
381	<p>
382	To create a user account, we first enter their credentials, followed by
383	its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
384	In the next example, we create a user called "john".
385	</p>
386
387	<pre caption="Creating a user account">
388	# <i>useradd -m -G users john</i>
389	# <i>passwd john</i>

391	Re-enter password: <comment>(Re-enter john's password)</comment>
392	</pre>
393
394	<p>
395	You can change your user id from root to the newly created user by using
396	<c>su</c>:

406	<title>Optional: Viewing Documentation while Installing</title>
407	<body>
408
409	<p>
410	If you want to view the Gentoo Handbook (either from-CD or online) during the
411	installation, make sure you have created a user account (see <uri
412	link="#useraccounts">Optional: User Accounts</uri>). Then press <c>Alt-F2</c> to
413	go to a new terminal and log in.
414	</p>
415
416	<p>
417	If you want to view the documentation on the CD you can immediately run
418	<c>links2</c> to read it:
419	</p>
420
421	<pre caption="Viewing the on-CD documentation">
422	# <i>links2 /mnt/cdrom/docs/handbook/html/index.html</i>
423	</pre>
424
425	<p>
426	However, it is preferred that you use the online Gentoo Handbook as it will be
427	more recent than the one provided on the CD. You can view it using <c>links2</c>
428	as well, but only after having completed the <e>Configuring your Network</e>
429	chapter (otherwise you won't be able to go on the Internet to view the
430	document):
431	</p>
432
433	<pre caption="Viewing the Online Documentation">
434	# <i>links2 http://www.gentoo.org/doc/en/handbook/handbook-sparc.xml</i>

444	<title>Optional: Starting the SSH Daemon</title>
445	<body>
446
447	<p>
448	If you want to allow other users to access your computer during the
449	Gentoo installation (perhaps because those users are going to help you
450	install Gentoo, or even do it for you), you need to create a user
451	account for them and perhaps even provide them with your root password
452	(<e>only</e> do that <e>if</e> you <b>fully trust</b> that user).
453	</p>
454
455	<p>
456	To fire up the SSH daemon, execute the following command:
457	</p>
458
459	<pre caption="Starting the SSH daemon">
460	# <i>/etc/init.d/sshd start</i>
461	</pre>
462
463	<p>
464	To be able to use sshd, you first need to set up your networking. Continue with
465	the chapter on <uri link="?part=1&chap=3">Configuring your Network</uri>.
