90	<p>
91	Gentoo Linux can be installed using one of three <e>stage</e> tarball files.
92	The one you choose depends on how much of the system you want to compile
93	yourself. The <e>stage1</e> tarball is used when you want to bootstrap and
94	build the entire system from scratch. The <e>stage2</e> tarball is used for
95	building the entire system from a bootstrapped "semi-compiled" state.
96	The <e>stage3</e> tarball already contains a basic Gentoo Linux system that has
97	been built for you. As we will explain later, you can also install
98	Gentoo without compiling anything (except your kernel and some optional
99	packages). If you want this, you have to use a <e>stage3</e> tarball.

		567	If you have an OldWorld Mac the bootable portion of the livecd can't be used.
		568	The most simple solution is to use MacOS to bootstrap into a Linux environment
		569	with a tool called BootX. Boot floppies are being prepared for Macs without
		570	MacOS, but they are not available at this time.
		571	</p>
		572	<p>
		573	First, download <uri link="http://penguinppc.org/projects/bootx/">BootX</uri>
		574	and unpack the archive. Copy the the <c>BootX Extension</c> from the unpacked
		575	archive into <c>Extensions Folder</c> and the BootX App Control Panel into
		576	<c>Control Panels</c>, both of which are located in your MacOS System Folder.
		577	Next, create a folder called "Linux Kernels" in your System folder and copy the
		578	<c>G3G4</c> kernel from the CD to this folder. Finally, copy <c>G3G4.igz</c>
		579	from the Installation CD <path>boot</path> folder into the MacOS
		580	<c>System Folder</c>.
		581	</p>
		582	<p>
		583	To prepare BootX, start the BootX App Control Panel. First select the Options
		584	dialog and check <c>Use Specified RAM Disk</c> and select <c>G3G4.igz</c> from
		585	your System Folder. Continue back to the initial screen and ensure that the
		586	ramdisk size is at least <c>32000</c>. Finally, set the kernel arguments as
		587	shown below:
		588	</p>
		589
		590	<pre caption="BootX kernel arguments">

		594	The kernel parameters in the yaboot section above are also applicable here.

		596	<p>
		597	Check once more to make sure the settings are correct and then save the
