Gentoo Linux can be installed using a <e>stage3</e> tarball file.
|
| 92 |
Such a tarball is an archive that contains a minimal environment from
|
| 93 |
which you can succesfully install Gentoo Linux onto your system.
|
| 94 |
</p>
|
| 95 |
|
| 96 |
<p>
|
| 97 |
Installations using a stage1 or stage2 tarball file are not documented in the
|
| 98 |
Gentoo Handbook - please read the <uri link="/doc/en/faq.xml#stage12">Gentoo
|
| 99 |
FAQ</uri> on these matters.

<title>Gentoo Universal Installation CD</title>
|

<body>
|

|

<p>
|
| 109 |
An Installation CD is a bootable medium which contains a self-sustained Gentoo
|
| 110 |
environment. It allows you to boot Linux from the CD. During the boot process
|
| 111 |
your hardware is detected and the appropriate drivers are loaded. The Gentoo
|
| 112 |
Installation CDs are maintained by Gentoo developers.
|
| 113 |
</p>
|
| 114 |
|
| 115 |
<p>
|
| 116 |
There currently are two Installation CDs available:
|
| 117 |
</p>
|
| 118 |
|
| 119 |
<ul>
|
| 120 |
<li>
|
| 121 |
The Universal Installation CD contains everything you need to install
|
| 122 |
Gentoo. It provides stage3 files for common architectures, source code
|
| 123 |
for the extra applications you need to choose from and, of course, the
|
| 124 |
installation instructions for your architecture.
|
| 125 |
</li>
|
| 126 |
<li>
|
| 127 |
The Minimal Installation CD contains only a minimal environment that allows
|
| 128 |
you to boot up and configure your network so you can connect to the
|
| 129 |
Internet. It does not contain any additional files and cannot be used
|
| 130 |
during the current installation approach.
|
| 131 |
</li>
|
| 132 |
</ul>
|
| 133 |
|
| 134 |
<p>
|
| 135 |
Gentoo also provides a Package CD. This is not an Installation CD but an
|
| 136 |
additional resource that you can exploit during the installation of your Gentoo
|
| 137 |
system. It contains prebuilt packages (also known as the GRP set) that allow
|
| 138 |
you to easily and quickly install additional applications (such as
|
| 139 |
OpenOffice.org, KDE, GNOME, ...) immediately after the Gentoo installation and
|
| 140 |
right before you update your Portage tree.
|
| 141 |
</p>
|
| 142 |
|
| 143 |
<p>
|
| 144 |
The use of the Package CD is covered later in this document.

<title>Downloading and Burning the Installation CD</title>
|
| 155 |
<body>
|
| 156 |
|
| 157 |
<p>
|
| 158 |
You can download the Universal Installation CD (and, if you want to, the
|
| 159 |
Packages CD as well) from one of our <uri
|
| 160 |
link="/main/en/mirrors.xml">mirrors</uri>. The Installation CDs are located in
|
| 161 |
the <path><keyval id="release-dir"/>installcd</path> directory; the Package CDs
|
| 162 |
are located in the <path><keyval id="release-dir"/>packagecd</path> directory.
|
| 163 |
</p>
|
| 164 |
|
| 165 |
<p>
|
| 166 |
Inside those directories you'll find ISO files. Those are full CD images which
|
| 167 |
you can write on a CD-R.
|
| 168 |
</p>
|
| 169 |
|
| 170 |
<p>
|
| 171 |
After downloading the file, you can verify its integrity to see if it is
|
| 172 |
corrupted or not:
|
| 173 |
</p>
|
| 174 |
|
| 175 |
<ul>
|
| 176 |
<li>
|
| 177 |
You can check its MD5 checksum and compare it with the MD5 checksum we
|
| 178 |
provide (for instance with the <c>md5sum</c> tool under Linux/Unix or
|
| 179 |
<uri link="http://www.etree.org/md5com.html">md5sum</uri> for Windows).
|
| 180 |
Verifying MD5 checksums with Mac OS X is described in the <uri
|
| 181 |
link="/doc/en/gentoo-ppc-faq.xml#doc_chap1">Gentoo PPC FAQ</uri>.
|
| 182 |
</li>
|
| 183 |
<li>
|
| 184 |
You can verify the cryptographic signature that we provide. You need to
|
| 185 |
obtain the public key we use (0x17072058) before you proceed though.
|
| 186 |
</li>
|
| 187 |
</ul>
|
| 188 |
|
| 189 |
<p>
|
| 190 |
To fetch our public key using the GnuPG application, run the following command:
|
| 191 |
</p>
|
| 192 |
|
| 193 |
<pre caption="Obtaining the public key">
|
| 194 |
$ <i>gpg --keyserver subkeys.pgp.net --recv-keys 0x17072058</i>
|
| 195 |
</pre>
|
| 196 |
|
| 197 |
<p>
|
| 198 |
Now verify the signature:
|
| 199 |
</p>
|
| 200 |
|
| 201 |
<pre caption="Verify the cryptographic signature">
|
| 202 |
$ <i>gpg --verify <signature file> <downloaded iso></i>
|
| 203 |
</pre>
|
| 204 |
|
| 205 |
<p>
|
| 206 |
To burn the downloaded ISO(s), you have to select raw-burning. How you
|
| 207 |
do this is highly program-dependent. We will discuss <c>cdrecord</c> and
|
| 208 |
<c>K3B</c> here; more information can be found in our <uri
|
| 209 |
link="/doc/en/faq.xml#isoburning">Gentoo FAQ</uri>.
|
| 210 |
</p>
|
| 211 |
|
| 212 |
<ul>
|
| 213 |
<li>
|
| 214 |
With cdrecord, you simply type <c>cdrecord dev=/dev/hdc <downloaded iso
|
| 215 |
file></c> (replace <path>/dev/hdc</path> with your CD-RW drive's device
|
| 216 |
path).
|
| 217 |
</li>
|
| 218 |
<li>
|
| 219 |
With K3B, select <c>Tools</c> > <c>Burn CD Image</c>. Then you can locate
|
| 220 |
your ISO file within the 'Image to Burn' area. Finally click <c>Start</c>.
|

<body>
|

<p>
|
| 231 |
On NewWorld machines place the Installation CD in the CD-ROM and reboot the
|
| 232 |
system. When the system-start-bell sounds, simply hold down the 'C' until the
|
| 233 |
CD loads.
|
| 234 |
</p>
|
| 235 |
|
| 236 |
<p>
|
| 237 |
After the Installation CD loaded, you will be greeted by a friendly welcome
|
| 238 |
message and a <e>boot:</e> prompt at the bottom of the screen.
|
| 239 |
</p>
|
| 240 |
|
| 241 |
<p>
|
| 242 |
We provide one generic kernel, <e>apple</e>. This kernel is built with support
|
| 243 |
for multiple CPUs, but it will boot on single processor machines as well.
|
| 244 |
</p>
|
| 245 |
|
| 246 |
<p>
|
| 247 |
You can tweak some kernel options at this prompt. The following table lists
|
| 248 |
some of the available boot options you can add:

This option takes one of the following vendor-specific tags:
|
| 260 |
<c>nvidiafb</c>, <c>radeonfb</c>, <c>rivafb</c>, <c>atyfb</c>,
|
| 261 |
<c>aty128</c> or <c>ofonly</c>. You can follow this tag with the resolution
|
| 262 |
refresh rate and color depth you want to use. For instance,
|
| 263 |
<c>video=radeonfb:1280x1024@75-32</c> will select the ATI Radeon frame buffer
|
| 264 |
at a resolution of 1280x1024 with a refresh rate of 75Hz and a color depth of
|
| 265 |
32 bits. If you are uncertain what to choose, and the default doesn't work,

<c>video=ofonly</c> will most certainly work.

To use the above options, at the <e>boot:</e> prompt, type <e>apple</e> followed
|
| 303 |
by the desired option. In the example below, we'll force the kernel to use the
|
| 304 |
Open Firmware framebuffer instead of the device specific driver.

If you don't need to add any options, just hit enter at this prompt, and a

<body>
|
| 322 |
|
| 323 |
<p>
|
| 324 |
On the Pegasos simply insert the CD and at the SmartFirmware boot-prompt type
|
| 325 |
<c>boot cd /boot/menu</c>. This will open a small bootmenu where you can choose
|
| 326 |
between several preconfigured video configs. If you need any special boot
|
| 327 |
options you can append them to the command-line just like with Yaboot above.
|
| 328 |
For example: <c>boot cd /boot/pegasos video=radeonfb:1280x1024@75 mem=256M</c>.
|
| 329 |
The default kernel options (in case something goes wrong and you need it) are
|
| 330 |
preconfigured with <c>console=ttyS0,115200 console=tty0 init=/linuxrc
|
| 331 |
looptype=squashfs loop=/image.squashfs cdroot root=/dev/ram0</c>.

<title>Alternative: Booting the Installation CD with BootX</title>
|
| 339 |
<body>
|
| 340 |
|
| 341 |
<p>
|
| 342 |
If you have an OldWorld Mac the bootable portion of the livecd can't be used.
|
| 343 |
The most simple solution is to use MacOS 9 or earlier to bootstrap into a Linux
|
| 344 |
environment with a tool called BootX.
|
| 345 |
</p>
|
| 346 |
|
| 347 |
<p>
|
| 348 |
First, download <uri link="http://penguinppc.org/bootloaders/bootx/">BootX</uri>
|
| 349 |
and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
|
| 350 |
archive into <c>Extensions Folder</c> and the BootX App Control Panel into
|
| 351 |
<c>Control Panels</c>, both of which are located in your MacOS System Folder.
|
| 352 |
Next, create a folder called "Linux Kernels" in your System folder and copy the
|
| 353 |
<c>apple</c> kernel from the CD to this folder. Finally, copy <c>apple.igz</c>
|
| 354 |
from the Installation CD <path>boot</path> folder into the MacOS
|
| 355 |
<c>System Folder</c>.
|
| 356 |
</p>
|
| 357 |
|
| 358 |
<p>
|
| 359 |
To prepare BootX, start the BootX App Control Panel. First select the Options
|
| 360 |
dialog and check <c>Use Specified RAM Disk</c> and select <c>apple.igz</c> from
|
| 361 |
your System Folder. Continue back to the initial screen and ensure that the
|
| 362 |
ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
|
| 363 |
shown below:
|
| 364 |
</p>
|
| 365 |
|
| 366 |
<pre caption="BootX kernel arguments">
|
| 367 |
cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0
|
| 368 |
</pre>
|
| 369 |
|
| 370 |
<note>
|
| 371 |
The kernel parameters in the yaboot section above are also applicable here. You
|
| 372 |
can append any of those options to the kernel arguments above.
|
| 373 |
</note>
|
| 374 |
|
| 375 |
<p>
|
| 376 |
Check once more to make sure the settings are correct and then save the
|
| 377 |
configuration. This saves typing just in case it doesn't boot or something is
|
| 378 |
missing. Press the Linux button at the top of the window. If everything goes
|
| 379 |
correctly, it should boot into the Installation CD. Continue with
|
| 380 |

You will be greeted by a root ("#") prompt on the current console. You can also
|
| 392 |
switch to other consoles by pressing Alt-F2, Alt-F3 and Alt-F4. Get
|
| 393 |
back to the one you started on by pressing Alt-F1. Due to the keyboard layout,
|
| 394 |
you may need to press Alt-fn-Fx on Apple machines.
|
| 395 |
</p>
|
| 396 |
|
| 397 |
<p>
|
