70<title>The Gentoo Installation Approaches</title>
71<subsection>
72<title>Introduction</title>
73<body>
74
75<p>
76Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
77A stage file is a tarball (compressed archive) that contains a minimal
78environment.
79</p>
80
81<ul>
82 <li>
83 A stage1 file contains nothing more than a compiler, Portage (Gentoo's
84 software management system) and a couple of packages on which the compiler
85 or Portage depends.
86 </li>
87 <li>
88 A stage2 file contains a so-called bootstrapped system, a minimal
89 environment from which one can start building all other necessary
90 applications that make a Gentoo environment complete.
91 </li>
92 <li>
93 A stage3 file contains a prebuilt minimal system which is almost fully
94 deployable. It only lacks a few applications where you, the Gentoo user,
95 needs to choose which one you want to install.
96 </li>
97</ul>
98
99<p>
100To help you decide what stage file you want to use, we have written down the
101major advantages and disadvantages of each stage file.

106<subsection>
107<title>A Stage1 Approach</title>
108<body>
109
110<p>
111A <e>stage1</e> is used when you want to bootstrap and build the entire system
112from scratch.
113</p>
114
115<p>
116Starting from a stage1 allows you to have total control over the
117optimization settings and optional build-time functionality that is
118initially enabled on your system. This makes <e>stage1</e> installs good for
119power users who know what they are doing. It is also a great
120installation method for those who would like to know more about the
121inner workings of Gentoo Linux.

166<body>
167
168<p>
169A <e>stage2</e> is used for building the entire system from a bootstrapped
170"semi-compiled" state.
171</p>
172
173<p>
174Stage2 installs allow you to skip the bootstrap process; doing this
175is fine if you are happy with the optimization settings that we chose
176for your particular stage2 tarball.

219<title>A Stage3 Approach</title>
220<body>
221
222<p>
223A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
224built for you. You will only need to build a few packages of which we can't
225decide for you which one to choose.
226</p>
227
228<p>
229Choosing to go with a stage3 allows for the fastest install of Gentoo
230Linux, but also means that your base system will have the optimization
231settings that we chose for you (which to be honest, are good settings
232and were carefully chosen to enhance performance while maintaining
233stability). Stage3 is also required if you want to install Gentoo using
234prebuilt packages or without a network connection.
235</p>

247 <th>-</th>
248 <ti>You cannot tweak the base system - it's built already</ti>
249</tr>
250</table>
251
252<p>
253You might be interested to know that, if you decide to use different
254optimization settings after having installed Gentoo, you will be able to
255recompile your entire system with the new optimization settings.

484If you have an OldWorld Mac the bootable portion of the livecd can't be used.
485Instead you need to download <uri
486link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working
487MacOS installed on your system. You need to copy the <c>BootX Extension</c> from
488the unpacked archive-file into the <c>Extensions Folder</c> and make a new
489directory called <c>Linux Kernels</c> in the System Folder. In the next step you
490need to copy the files <c>G3G4kernel</c> and <c>initrd.img.gz</c> from the
491Installation CD <path>boot</path> folder into the <c>Linux Kernels</c>
492directory. Then reboot the system and wait for BootX to load. After BootX
493loaded you still have to set up a few items. In the options dialog you need
494to check <c>Use Specified RAM Disk</c> and select the <c>initrd.img.gz</c>
495which you put in the <c>Linux Kernels</c> directory. The ramdisk size should

393<title>Alternative: Booting the Installation CD with BootX</title>
394<body>
395
396<p>
397If you have an OldWorld Mac the bootable portion of the livecd can't be used.
398The most simple solution is to use MacOS 9 or earlier to bootstrap into a Linux
399environment with a tool called BootX.
400</p>
401
402<p>
403First, download <uri link="http://penguinppc.org/bootloaders/bootx/">BootX</uri>
404and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
405archive into <c>Extensions Folder</c> and the BootX App Control Panel into
406<c>Control Panels</c>, both of which are located in your MacOS System Folder.
407Next, create a folder called "Linux Kernels" in your System folder and copy the
408<c>ppc32</c> kernel from the CD to this folder. Finally, copy <c>ppc32.igz</c>
409from the Installation CD <path>boot</path> folder into the MacOS
410<c>System Folder</c>.
411</p>
412
413<p>
414To prepare BootX, start the BootX App Control Panel. First select the Options
415dialog and check <c>Use Specified RAM Disk</c> and select <c>ppc32.igz</c> from
416your System Folder. Continue back to the initial screen and ensure that the
417ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
418shown below:
419</p>
420
421<pre caption="BootX kernel arguments">
422cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0
423</pre>
424
425<note>
426The kernel parameters in the yaboot section above are also applicable here. You
427can append any of those options to the kernel arguments above.
428</note>
429
430<p>
431Check once more to make sure the settings are correct and then save the
432configuration. This saves typing just in case it doesn't boot or something is
433missing. Press the Linux button at the top of the window. If everything goes
434correctly, it should boot into the Installation CD. Continue with

624When the Installation CD boots, it tries to detect all your hardware devices and
625loads the appropriate kernel modules to support your hardware. In the
626vast majority of cases, it does a very good job. However, in some cases, it may
627not auto-load the kernel modules you need. If the PCI auto-detection missed some
628of your system's hardware, you will have to load the appropriate kernel modules
629manually.

633In the next example we try to load the <c>airport</c> module. This module
634supports only the old Airport cards (b-net). AirportExtreme is currently not
