=== PPC Specifics for Fedora ===
This section covers specific information about Fedora and the PPC hardware platform.
==== Hardware Requirements for PPC ====
<noinclude>[[Category:Release Notes]]<noinclude>
===== Processor and memory =====
* Minimum CPU: PowerPC G3 / POWER3
* Fedora {{Template:DocsDict/BeatsVer}}
  supports the “New World” generation of Apple Power Macintosh, shipped from circa 1999 onward. Although "Old World" machines should work, they require a special bootloader which is not included in the Fedora distribution.
  * Fedora {{Template:DocsDict/BeatsVer}}
  supports IBM RS/6000, pSeries, iSeries, and Cell Broadband Engine machines.
  * Fedora {{Template:DocsDict/BeatsVer}}
  also supports the Sony PlayStation 3 and Genesi Pegasos II and Efika.
  * Fedora {{Template:DocsDict/BeatsVer}}
  includes new hardware support for the P.A. Semiconductor 'Electra' machines.
  * Recommended for text-mode: 233 MHz G3 or better, 128MiB RAM.
* Recommended for graphical: 400 MHz G3 or better, 256MiB RAM.
===== Hard disk space =====
The complete packages can occupy over 9 GB of disk space.  Final size is entirely determined by the installing spin and the packages selected during installation.  Additional disk space is required during installation to support the installation environment. This additional disk space corresponds to the size of <code>/Fedora/base/stage2.img</code> (on Installation Disc 1) plus the size of the files in <code>/var/lib/rpm</code> on the installed system.
In practical terms, additional space requirements may range from as little as 90 MiB for a minimal installation to as much as an additional 175 MiB for a larger installation.
Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation.
==== 4 KiB Pages on 64-bit machines ====
After a brief experiment with 64KiB pages in Fedora Core 6, the PowerPC64 kernel has now been switched back to 4KiB pages. The installer should reformat any swap partitions automatically during an upgrade.
==== The Apple keyboard ====
The <code>Option</code> key on Apple systems is equivalent to the <code>Alt</code> key on the PC. Where documentation and the installer refer to the <code>Alt</code> key, use the <code>Option</code> key. For some key combinations you may need to use the <code>Option</code> key in conjunction with the <code>Fn</code> key, such as <code>Option</code>-<code>Fn</code>-<code>F3</code> to switch to virtual terminal tty3.
==== PPC installation notes ====
Fedora Installation Disc 1 is bootable on supported hardware. In addition, a bootable CD image appears in the <code>images/</code> directory of this disc. These images behave differently according to your system hardware:
* On most machines, the bootloader automatically boots the appropriate 32-bit or 64-bit installer from the install disc.
* 64-bit IBM pSeries (POWER4/POWER5), current iSeries models
After using Open''''''Firmware to boot the CD, the bootloader, <code>yaboot</code>, automatically boots the 64-bit installer.
* IBM "Legacy" iSeries (POWER4)
So-called "Legacy" iSeries models, which do not use Open''''''Firmware, require use of the boot image located in the <code>images/iSeries</code> directory of the installation tree.
* 32-bit CHRP (IBM RS/6000 and others)
After using Open''''''Firmware to boot the CD, select the <code>linux32</code> boot image at the <code>boot:</code> prompt to start the 32-bit installer. Otherwise, the 64-bit installer starts and fails.
* Genesi Pegasos II / Efika 5200B
The Fedora kernel supports both Pegasos and Efika without the need to use the "Device Tree Supplement" from However, the lack of full support for ISO9660 in the firmware means that booting via yaboot from the CD is not possible. Boot the 'netboot' image instead, either from the CD or over the network. Because of the size of the image, you must set the firmware's<code>load-base</code> variable to load files at a high address such as 32MiB instead of the default 4MiB:
<pre>setenv load-base 0x2000000
At the Open''''''Firmware prompt, enter the following command to boot the Efika update, if necessary, or the netboot image from the CD:
boot cd: /images/netboot/ppc32.img
Or from the network:
boot eth ppc32.img
You must also manually configure Open''''''Firmware to make the installed Fedora system bootable. To do this, set the <code>boot-device</code> and <code>boot-file</code> environment variables appropriately, to load yaboot from the <code>/boot</code> partition. For example, a default installation might require the following:
<pre>setenv boot-device hd:0
setenv boot-file /yaboot/yaboot
setenv auto-boot? true
* PA Semi Electra
The Electra firmware does not yet support yaboot; to install on Electra, you can boot the <code>ppc64.img</code> netboot image. After the installation, you will need to manually configure the firmware to load the installed kernel and initrd from the <code>/boot</code> partition.
Refer to the firmware documentation for further details.
* Sony Play''''''Station 3
For installation on Play''''''Station 3, first update to firmware 1.60 or later. The "Other OS" boot loader must be installed into the flash, following the instructions at [] . A suitable boot loader image can be found on Sony's "ADDON" CD, available from
Once the boot loader is installed, the Play''''''Station 3 should be able to boot from the Fedora install media. Please note that network installation works best with NFS, since that takes less memory than FTP or HTTP methods. Using the <code>text</code> option also reduces the amount of memory taken by the installer.
For more info on Fedora and the Play''''''Station3 or Fedora on PowerPC in general, join the [ Fedora-PPC mailing list] or the <code>#fedora-ppc</code> channel on [ FreeNode] .
* Network booting
Combined images containing the installer kernel and ramdisk are located in the <code>images/netboot/</code> directory of the installation tree. They are intended for network booting with TFTP, but can be used in many ways.
The <code>yaboot</code> loader supports TFTP booting for IBM pSeries and Apple Macintosh.  The Fedora Project encourages the use of <code>yaboot</code> over the <code>netboot</code> images.
===== PPC Specific packages =====
* The <code>ppc64-utils</code> package has been split out into individual packages reflecting upstream packaging (<code>ps3pf-utils</code>, <code>powerpc-utils</code>, <code>powerpc-utils-papr</code>). Although the <code>mkzimage</code> command is no longer supplied, you can use the <code>wrapper</code> script from the <code>kernel-bootwrapper</code> package:
<pre>wrapper -i initrd-${KERN_VERSION}.img -o zImage-${KERN_VERSION}.img vmlinuz-${KERN_VERSION}
