+Apple New World machines are fairly straightforward to configure. The first
+partition is always an <e>Apple Partition Map</e>. This partition keeps track
+of the layout of the disk. You cannot remove this partition. The next
+partition should always be a bootstrap partition. This partition contains a

+configuration file. This partition is <e>not</e> the same as a
+<path>/boot</path> partition as found on other architectures. After the boot
+partition, the usual Linux filesystems are placed, according to the scheme
+below. The swap partition is a temporary storage place for when your system
+runs out of physical memory. The root partition will contain the filesystem
+that Gentoo is installed on. If you wish to dual boot, the OSX partition
+can go anywhere after the bootstrap partition to insure that yaboot starts

+Apple Old World machines are a bit more complicated to configure. The first
+partition is always an <e>Apple Partition Map</e>. This partition keeps track
+of the layout of the disk. You cannot remove this partition. If you are using
+BootX, the configuration below assumes that MacOS is installed on a seperate

+Disk Drivers" such as <path>Apple_Driver63, Apple_Driver_ATA, Apple_FWDriver,
+Apple_Driver_IOKit, Apple_Patches</path> and the MacOS install. If you are
+using Quik, you will need to create a boot partition to hold the kernel, unlike
+other Apple boot methods. After the boot partition, the usual Linux filesystems
+are placed, according to the scheme below. The swap partition is a temporary
+storage place for when your system runs out of physical memory. The root
+partition will contain the filesystem that Gentoo is installed on.
