<p>
|
| 78 |
The <e>Gentoo Installation CDs</e> are bootable CDs which contain a
|
| 79 |
self-sustained Gentoo environment. They allow you to boot Linux from the CD.
|
| 80 |
During the boot process your hardware is detected and the appropriate drivers
|
| 81 |
are loaded. They are maintained by Gentoo developers.
|
| 82 |
</p>
|
| 83 |
|
| 84 |
<p>
|
| 85 |
All Installation CDs allow you to boot, set up networking, initialize your
|
| 86 |
partitions and start installing Gentoo from the Internet.
|
| 87 |
</p>
|
| 88 |
<!--
|

<p>
|
| 90 |
If you wish to install Gentoo without a working Internet connection, please use
|
| 91 |
the installation instructions described in the <uri
|
| 92 |
link="2008.0/index.xml">Gentoo 2008.0 Handbooks</uri>.
|
| 93 |
</p>
|
| 94 |
|
| 95 |
<p>
|
| 96 |
The two Installation CDs that we currently provide are:
|
| 97 |
</p>
|
| 98 |
|
| 99 |
<ul>
|
| 100 |
<li>
|
| 101 |
The Gentoo <e>Minimal</e> Installation CD, a small, no-nonsense, bootable
|
| 102 |
CD which sole purpose is to boot the system, prepare the networking and
|
| 103 |
continue with the Gentoo installation.
|
| 104 |
</li>
|
| 105 |
<li>
|
| 106 |
The Gentoo <e>Universal</e> Installation CD, a bootable CD with the same
|
| 107 |
abilities as the Minimal Installation CD. Additionally, it contains
|
| 108 |
several stage3 tarballs (optimized for the individual subarchitectures).
|
| 109 |
</li>
|
| 110 |
</ul>
|
| 111 |
|
| 112 |
<p>
|
| 113 |
To help you decide which Installation CD you need, we have written down the
|
| 114 |
major advantages and disadvantages of each Installation CD.

<title>The Stage3 Tarball</title>
|

<body>
|
| 184 |
|
| 185 |
<p>
|
| 186 |
A stage3 tarball is an archive containing a minimal Gentoo environment,
|
| 187 |
suitable to continue the Gentoo installation using the instructions in this
|
| 188 |
manual. Previously, the Gentoo Handbook described the installation using one of
|
| 189 |
three 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>
|
| 194 |
</p>
|
| 195 |
|
| 196 |
<p>
|
| 197 |
Stage3 tarballs can be downloaded from <path><keyval
|
| 198 |
id="release-dir"/>current-stage3/</path> on any of the <uri

<title>Choosing a userland</title>
|
| 207 |
<body>
|
| 208 |
|
| 209 |
<p>
|
| 210 |
On PPC64, the kernel is 64-bit and the <e>userland</e> can be 32-bit or 64-bit.
|
| 211 |
The userland is basically the applications you are running, such as <c>bash</c>
|
| 212 |
or <c>firefox</c>. They can be compiled and run in either 64-bit or
|
| 213 |
32-bit modes. The Gentoo/PPC64 team provides both 32-bit and 64-bit userlands,
|
| 214 |
so which one should you use?
|
| 215 |
</p>
|
| 216 |
|
| 217 |
<p>
|
| 218 |
You may have heard that 64-bit applications are better, but in fact, 32-bit
|
| 219 |
applications take up slightly less memory and often run a little bit faster than
|
| 220 |
64-bit applications.
|
| 221 |
</p>
|
| 222 |
|
| 223 |
<p>
|
| 224 |
You really only need 64-bit applications when you need more memory than a 32-bit
|
| 225 |
userland allows, or if you do a lot of 64-bit number crunching. If you have 4GB
|
| 226 |
or more of memory or you run scientific applications, you should choose the
|
| 227 |
64-bit userland. Otherwise, choose the 32-bit userland, as it is recommended by
|
| 228 |
the Gentoo/PPC64 developers.
|
| 229 |
</p>
|
| 230 |
|
| 231 |
<p>
|
| 232 |
Additionally, the 32-bit userland has been available in Portage longer than the
|
| 233 |
64-bit userland has. This means that there are more applications tested in the
|
| 234 |
32-bit userland that just work "out of the box." Many applications compiled for
|
| 235 |
the 64-bit userland may be just as stable as the 32-bit version, but they
|
| 236 |
haven't been tested yet. Though testing isn't difficult to do, it can be
|
| 237 |
annoying and time consuming if you want to use many untested 64-bit
|
| 238 |
applications. Also, some programs just won't run in the 64-bit userland until
|
| 239 |
their code is fixed, such as OpenOffice.

<title>Download, Burn and Boot a Gentoo Installation CD</title>

<subsection>

<title>Downloading and Burning the Installation CDs</title>
|
| 250 |
<body>
|
| 251 |
|
| 252 |
<p>
|
| 253 |
You have chosen to use a Gentoo Installation CD. We'll first start by
|
| 254 |
downloading and burning the chosen Installation CD. We previously discussed the
|
| 255 |
several available Installation CDs, but where can you find them?
|
| 256 |
</p>
|
| 257 |
|
| 258 |
<p>
|
| 259 |
You can download any of the Installation CDs from one of our <uri
|
| 260 |
link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
|
| 261 |
the <path><keyval id="release-dir"/>current-iso/</path> directory.
|
| 262 |
</p>
|
| 263 |
|
| 264 |
<p>
|
| 265 |
Inside that directory you'll find ISO files. Those are full CD images
|
| 266 |
which you can write on a CD-R.
|
| 267 |
</p>
|
| 268 |
|
| 269 |
<p>
|
| 270 |
In case you wonder if your downloaded file is corrupted or not, you can check
|
| 271 |
its MD5 checksum and compare it with the MD5 checksum we provide (such as
|
| 272 |
<path><keyval id="min-cd-name"/>.DIGESTS</path>). You can check the MD5
|
| 273 |
checksum with the <c>md5sum</c> tool under Linux/Unix or <uri
|
| 274 |
link="http://www.etree.org/md5com.html">md5sum</uri> for Windows.
|
| 275 |
</p>
|
| 276 |
|
| 277 |
<p>
|
| 278 |
Another way to check the validity of the downloaded file is to use GnuPG to
|
| 279 |
verify the cryptographic signature that we provide (the file ending with
|
| 280 |
<path>.asc</path>). Download the signature file and obtain the public keys whose
|
| 281 |
key ids can be found on the <uri link="/proj/en/releng/index.xml">release
|
| 282 |
engineering project site</uri>.
|
| 283 |
</p>
|
| 284 |
|
| 285 |
<pre caption="Obtaining the public key">
|
| 286 |
<comment>(... Substitute the key ids with those mentioned on the release engineering site ...)</comment>
|
| 287 |
$ <i>gpg --keyserver subkeys.pgp.net --recv-keys 96D8BF6D 2D182910 17072058</i>
|
| 288 |
</pre>
|
| 289 |
|
| 290 |
<p>
|
| 291 |
Now verify the signature:
|
| 292 |
</p>
|
| 293 |
|
| 294 |
<pre caption="Verify the files">
|
| 295 |

|
| 296 |
$ <i>gpg --verify <downloaded iso.DIGESTS.asc></i>
|
| 297 |
<comment>(Verify the checksum)</comment>
|
| 298 |
$ <i>sha1sum -c <downloaded iso.DIGESTS.asc></i>
|
| 299 |
</pre>

<p>
|
| 302 |
To burn the downloaded ISO(s), you have to select raw-burning. How you
|
| 303 |
do this is highly program-dependent. We will discuss <c>cdrecord</c> and
|
| 304 |
<c>K3B</c> here; more information can be found in our <uri
|
| 305 |
link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.

</p>
|
| 307 |
|
| 308 |
<ul>
|
| 309 |
<li>
|
| 310 |
With cdrecord, you simply type <c>cdrecord dev=/dev/hdc <downloaded iso
|
| 311 |
file></c> (replace <path>/dev/hdc</path> with your CD-RW drive's
|
| 312 |
device path).
|
| 313 |
</li>
|
| 314 |
<li>
|
| 315 |
With K3B, select <c>Tools</c> > <c>Burn CD Image</c>. Then you can locate
|
| 316 |
your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
|
| 317 |
</li>
|
| 318 |
<li>
|
| 319 |
With Mac OS X Panther, launch <c>Disk Utility</c> from
|
| 320 |
<path>Applications/Utilities</path>, select <c>Open</c> from the
|
| 321 |
<c>Images</c> menu, select the mounted disk image in the main window and
|
| 322 |
select <c>Burn</c> in the <c>Images</c> menu.
|
| 323 |
</li>
|
| 324 |
<li>
|
| 325 |
With Mac OS X Jaguar, launch <c>Disk Copy</c> from
|
| 326 |
<path>Applications/Utilities</path>, select <c>Burn Image</c> from the
|
| 327 |
<c>File</c> menu, select the ISO and click the <c>Burn</c> button.
|
| 328 |
</li>

<p>
|
| 338 |
Place the Installation CD in the CD-ROM and reboot the system. Hold down the
|
| 339 |
'C' key at bootup. You will be greeted by a friendly welcome message and a

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

The CD should autoboot on your pSeries box, but sometimes it does not. In that
|
| 417 |
case, you have to set up your cdrom as a bootable device in the multi-boot
|
| 418 |
menu. If you start your machine with a monitor and a keyboard attached, you can
|
| 419 |
reach the multi-boot menu pressing the F1 key on startup. But if you start your
|
| 420 |
machine using the serial console, then you have to press <c>1</c>. Press the
|
| 421 |
key when you see the beginning of the following line on the serial console:

The other option is to jump into Open Firmware and do it from there:

| 430 |

|

|

<ol>
|
| 433 |
<li>
|
| 434 |
Boot into Open Firmware: same procedure as getting into multi-boot
|
| 435 |
(described a few lines above), but use F8 and 8 instead of F1 and 1.
|
| 436 |
</li>
|
| 437 |
<li>Run the command 0> boot cdrom:1,yaboot</li>
|
| 438 |
<li>Stand back and enjoy!</li>
|
| 439 |
</ol>
|
| 440 |
|
| 441 |
<note>
|
| 442 |
If you get something like the following output, then Open Firmware isn't set up
|
| 443 |
correctly. Please use the multi-boot option described above.

You will be greeted by a root ("#") prompt on the current console. You can also
|
| 460 |
switch to other consoles by pressing Alt-fn-F2, Alt-fn-F3 and Alt-fn-F4. Get
|
| 461 |
back to the one you started on by pressing Alt-fn-F1.

If you are installing Gentoo on a system with a non-US keyboard, use
|
| 466 |
<c>loadkeys</c> to load the keymap for your keyboard. To list the available
|
| 467 |
keymaps, execute <c>ls /usr/share/keymaps/i386</c>.

|
