<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="2006.0/index.xml">Gentoo 2006.0 Handbooks</uri>. This is currently not
supported for the PPC64 architecture though.
</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>
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-ppc64-minimal-2006.0.iso</c> and takes up only 124 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-ppc64-universal-2006.0-32ul.iso</c> and uses 460 MB. 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>
  <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>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>

<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/ppc/2006.0/ppc64/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-ppc64-minimal-2006.0.iso.DIGESTS</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 subkeys.pgp.net --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>
  <li>
    With Mac OS X Panther, launch <c>Disk Utility</c> from
    <path>Applications/Utilities</path>, select <c>Open</c> from the
    <c>Images</c> menu, select the mounted disk image in the main window and
    select <c>Burn</c> in the <c>Images</c> menu.
  </li>
  <li>
    With Mac OS X Jaguar, launch <c>Disk Copy</c> from
    <path>Applications/Utilities</path>, select <c>Burn Image</c> from the
    <c>File</c> menu, select the ISO and click the <c>Burn</c> button.
  </li>
</ul>

</subsection>
<subsection>
<title>Default: Booting the Installation CD on an Apple/IBM</title>
<body>

<p>
Place the Installation CD in the CD-ROM and reboot the system. Hold down the 
'C' key at bootup. You will be greeted by a friendly welcome message and a 
<e>boot:</e> prompt at the bottom of the screen.
</p>

<p>
You are also able to tweak some kernel options at this prompt. The following
table lists the available boot options you can add:
</p>

<table>
<tr>
  <th>Boot Option</th>
  <th>Description</th>
</tr>
<tr>
  <ti><c>video</c></ti>
  <ti>
    This option takes one of the following vendor-specific tags:
    <c>radeonfb</c>, <c>rivafb</c>, <c>atyfb</c>, <c>aty128</c> or
    <c>ofonly</c>. You can follow this tag with the resolution and refreshrate
    you want to use. For instance <c>video=radeonfb:1280x1024@75</c>. If you are
    uncertain what to choose, <c>ofonly</c> will most certainly work.
  </ti>
</tr>
<tr>
  <ti><c>nol3</c></ti>
  <ti>
    Disables level 3 cache on some powerbooks (needed for at least the 17'')
  </ti>
</tr>
<tr>
  <ti><c>debug</c></ti>
  <ti>
    Enables verbose booting, spawns an initrd shell that can be used to debug
    the Installation CD
  </ti>
</tr>
<tr>
  <ti><c>sleep=X</c></ti>
  <ti>
    Wait X seconds before continuing; this can be needed by some very old SCSI
    CD-ROMs which don't speed up the CD quick enough
  </ti>
</tr>
<tr>
  <ti><c>bootfrom=X</c></ti>
  <ti>
    Boot from a different device
  </ti>
</tr>
</table>

<p>
At this prompt, hit enter, and a complete Gentoo Linux environment will be
loaded from the CD. Continue with <uri link="#booted">And When You're
Booted...</uri>.
</p>

</body>
</subsection>
<subsection>
<title>IBM pSeries</title>
<body>

<p>
The CD should autoboot on your pSeries box, but sometimes it does not.  In that
case, you have to set up your cdrom as a bootable device in the multi-boot
menu. If you start your machine with a monitor and a keyboard attached, you can
reach the multi-boot menu pressing the F1 key on startup. But if you start your
machine using the serial console, then you have to press <c>1</c>. Press the
key when you see the beginning of the following line on the serial console:
</p>

<pre caption="Hit the '1' key when this line appears">
memory      keyboard     network      scsi      speaker
</pre>

<p>
The other option is to jump into OpenFirmware and do it from there:
</p>

<ol>
  <li>
    Boot into OpenFirmware: same procedure as getting into multi-boot
    (described a few lines above), but use F8 and 8 instead of F1 and 1.
  </li>
  <li>Run the command 0> boot cdrom:1,yaboot</li>
  <li>Stand back and enjoy!</li>
</ol>

<note>
If you get something like the following output, then OpenFirmware isn't set up
correctly.  Please use the multi-boot option described above.
</note>

<pre caption="Output if OpenFirmwareF is not set up correctly">
0 > boot cdrom:1,yaboot
 ok
0 >
</pre>

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

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

<p>
If you are installing Gentoo on a system with a non-US keyboard, use
<c>loadkeys</c> to load the keymap for your keyboard. To list the available
keymaps, execute <c>ls /usr/share/keymaps/i386</c>.
</p>

<pre caption="Listing available keymaps">
<comment>(PPC uses x86 keymaps on most systems. The mac/ppc keymaps provided
 on the Installation CD are ADB keymaps and unusable with the 
 Installation CD kernel)</comment>
# <i>ls /usr/share/keymaps/i386</i>
</pre>

<p>
Now load the keymap of your choice:
</p>

<pre caption="Loading a keymap">
# <i>loadkeys be-latin1</i>
</pre>

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

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

<p>
When the Installation CD boots, it tries to detect all your hardware devices and
loads the appropriate kernel modules to support your hardware. In the
vast majority of cases, it does a very good job. However, in some cases it may 
not auto-load the kernel 
modules you need. If the PCI auto-detection missed some of your system's 
hardware, you will have to load the appropriate kernel modules manually. 
</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>
<title>Optional: Tweaking Hard Disk Performance</title>
<body>

<p>
If you are an advanced user, you might want to tweak the IDE hard disk
performance using <c>hdparm</c>. With the <c>-tT</c> options you can
test the performance of your disk (execute it several times to get a
more precise impression):
</p>

<pre caption="Testing disk performance">
# <i>hdparm -tT /dev/hda</i>
</pre>

<p>
To tweak, you can use any of the following examples (or experiment
yourself) which use <path>/dev/hda</path> as disk (substitute with your
disk):
</p>

<pre caption="Tweaking hard disk performance">
<comment>Activate DMA:</comment>                                       # <i>hdparm -d 1 /dev/hda</i>
<comment>Activate DMA + Safe Performance-enhancing Options:</comment>  # <i>hdparm -d 1 -A 1 -m 16 -u 1 -a 64 /dev/hda</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 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>links</c> to read it:
</p>

<pre caption="Viewing the on-CD documentation">
# <i>links /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.
</p>

<pre caption="Viewing the Online Documentation">
# <i>links http://www.gentoo.org/doc/en/handbook/handbook-ppc64.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>.

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

204	swift	1.1	<body>
205
206			<p>
207	swift	1.17	You have chosen to use a Gentoo Installation CD. We'll first start by
208			downloading and burning the chosen Installation CD. We previously discussed the
209			several available Installation CDs, but where can you find them?
210	swift	1.14	</p>
211
212			<p>
213	neysx	1.27	You can download any of the Installation CDs (and, if you want to, a Packages
214	swift	1.17	CD as well) from one of our <uri link="/main/en/mirrors.xml">mirrors</uri>. The
215	neysx	1.27	Installation CDs are located in the
216	fox2mike	1.29	<path>releases/ppc/2006.0/ppc64/installcd</path> directory.
217	swift	1.1	</p>
218
219			<p>
220	neysx	1.26	Inside that directory you'll find ISO-files. Those are full CD images
221	swift	1.1	which you can write on a CD-R.
222			</p>
223
224			<p>
225	swift	1.14	In case you wonder if your downloaded file is corrupted or not, you can
226			check its MD5 checksum and compare it with the MD5 checksum we provide (such as
227	fox2mike	1.29	<path>install-ppc64-minimal-2006.0.iso.DIGESTS</path>). You can check the MD5
228	swift	1.1	checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
229			link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
230			</p>
231
232			<p>
233	swift	1.14	Another way to check the validity of the downloaded file is to use GnuPG to
234			verify the cryptographic signature that we provide (the file ending with
235			<path>.asc</path>). Download the signature file and obtain the public key:
236	swift	1.1	</p>
237
238	swift	1.14	<pre caption="Obtaining the public key">
239	jkt	1.28	$ <i>gpg --keyserver subkeys.pgp.net --recv-keys 17072058</i>
240	swift	1.1	</pre>
241
242			<p>
243	swift	1.14	Now verify the signature:
244	swift	1.1	</p>
245
246	swift	1.14	<pre caption="Verify the cryptographic signature">
247			$ <i>gpg --verify <signature file> <downloaded iso></i>
248			</pre>
249	swift	1.1
250			<p>
251			To burn the downloaded ISO(s), you have to select raw-burning. How you
252	swift	1.14	do this is highly program-dependent. We will discuss <c>cdrecord</c> and
253			<c>K3B</c> here; more information can be found in our <uri
254			link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
255	swift	1.1	</p>
256
257			<ul>
258			<li>
259	swift	1.14	With cdrecord, you simply type <c>cdrecord dev=/dev/hdc <downloaded iso
260			file></c> (replace <path>/dev/hdc</path> with your CD-RW drive's
261	swift	1.16	device path).
262	swift	1.1	</li>
263			<li>
264	swift	1.14	With K3B, select <c>Tools</c> > <c>CD</c> > <c>Burn Image</c>. Then
265	swift	1.1	you can locate your ISO file within the 'Image to Burn' area. Finally click
266			<c>Start</c>.
267			</li>
268	swift	1.7	<li>
269			With Mac OS X Panther, launch <c>Disk Utility</c> from
270			<path>Applications/Utilities</path>, select <c>Open</c> from the
271			<c>Images</c> menu, select the mounted disk image in the main window and
272			select <c>Burn</c> in the <c>Images</c> menu.
273			</li>
274			<li>
275			With Mac OS X Jaguar, launch <c>Disk Copy</c> from
276			<path>Applications/Utilities</path>, select <c>Burn Image</c> from the
277			<c>File</c> menu, select the ISO and click the <c>Burn</c> button.
