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.

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.

159<title>A Stage2 Approach</title>
160<body>
161
162<p>
163A <e>stage2</e> is used for building the entire system from a bootstrapped
164"semi-compiled" state.
165</p>
166
167<p>
168Stage2 installs allow you to skip the bootstrap process; doing this
169is fine if you are happy with the optimization settings that we chose
170for your particular stage2 tarball.

207<title>A Stage3 Approach</title>
208<body>
209
210<p>
211A <e>stage3</e> installation contains a basic Gentoo Linux system that has been
212built for you. You will only need to build a few packages of which we can't
213decide for you which one to choose.
214</p>
215
216<p>
217Choosing to go with a stage3 allows for the fastest install of Gentoo
218Linux, but also means that your base system will have the optimization
219settings that we chose for you (which to be honest, are good settings
220and were carefully chosen to enhance performance while maintaining
221stability). Stage3 is also required if you want to install Gentoo using
222prebuilt packages or without a network connection.
223</p>
224
225<table>

227 <th>Stage3</th>

235 <th>-</th>
236 <ti>You cannot tweak the base system - it's built already</ti>
237</tr>
238</table>
239
240<p>
241You might be interested to know that, if you decide to use different
242optimization settings after having installed Gentoo, you will be able to
243recompile your entire system with the new optimization settings.

467If you have an OldWorld Mac the bootable portion of the livecd can't be used. 293
468Instead you need to download <uri
469link="http://penguinppc.org/projects/bootx/">BootX</uri> and have a working
470MacOS installed on your system. You need to copy the <c>BootX Extension</c> from
471the unpacked archive-file into the <c>Extensions Folder</c> and make a new
472directory called <c>Linux Kernels</c> in the System Folder. In the next step you
473need to copy the files <c>G3G4kernel</c> and <c>initrd.img.gz</c> from the
474LiveCD <path>boot</path> folder into the <c>Linux Kernels</c> directory. Then
475reboot the system and wait for BootX to load. After BootX loaded you still have
476to set up a few items. In the options dialog you need to check <c>Use Specified
477RAM Disk</c> and select the <c>initrd.img.gz</c> which you put in the <c>Linux
478Kernels</c> directory. The ramdisk size should be set to at least <c>32000</c>.
479Furthermore the kernel argument needs to be set to <c>rw init=/linuxrc

481Startup.

396<title>Alternative: Booting the Installation CD with BootX</title>
397<body>
398
399<p>
400If you have an OldWorld Mac the bootable portion of the livecd can't be used.
401The most simple solution is to use MacOS 9 or earlier to bootstrap into a Linux
402environment with a tool called BootX.
403</p>
404
405<p>
406First, download <uri link="http://penguinppc.org/bootloaders/bootx/">BootX</uri>
407and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
408archive into <c>Extensions Folder</c> and the BootX App Control Panel into
409<c>Control Panels</c>, both of which are located in your MacOS System Folder.
410Next, create a folder called "Linux Kernels" in your System folder and copy the
411<c>ppc32</c> kernel from the CD to this folder. Finally, copy <c>ppc32.igz</c>
412from the Installation CD <path>boot</path> folder into the MacOS
413<c>System Folder</c>.
414</p>
415
416<p>
417To prepare BootX, start the BootX App Control Panel. First select the Options
418dialog and check <c>Use Specified RAM Disk</c> and select <c>ppc32.igz</c> from
419your System Folder. Continue back to the initial screen and ensure that the
420ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
421shown below:
422</p>
423
424<pre caption="BootX kernel arguments">
425cdroot root=/dev/ram0 init=linuxrc loop=image.squashfs looptype=squashfs console=tty0
426</pre>
427
428<note>
429The kernel parameters in the yaboot section above are also applicable here. You
430can append any of those options to the kernel arguments above.
431</note>
432
433<p>
434Check once more to make sure the settings are correct and then save the
435configuration. This saves typing just in case it doesn't boot or something is
436missing. Press the Linux button at the top of the window. If everything goes
437correctly, it should boot into the Installation CD. Continue with

607When the LiveCD boots, it tries to detect all your hardware devices and
608loads the appropriate kernel modules to support your hardware. In the
609vast majority of cases, it does a very good job. However, in some cases, it may
610not auto-load the kernel modules you need. If the PCI auto-detection missed some
611of your system's hardware, you will have to load the appropriate kernel modules
612manually.

616In the next example we try to load the <c>airport</c> module (support for

676To create a user account, we first enter their credentials, followed by
677its password. We use <c>useradd</c> and <c>passwd</c> for these tasks.
