5. Architecture Specific Notes

This section provides notes that are specific to the supported hardware architectures of Fedora Core.

5.1. PPC Specifics for Fedora

This section covers any specific information you may need to know about Fedora Core and the PPC hardware platform.

5.1.1. PPC Hardware Requirements

5.1.1.1. Processor and Memory
  • Minimum CPU: PowerPC G3 / POWER4
  • Fedora Core 5 supports only the “New World” generation of Apple Power Macintosh, shipped from circa 1999 onward.
  • Fedora Core 5 also supports IBM eServer pSeries, IBM RS/6000, Genesi Pegasos II, and IBM Cell Broadband Engine machines.
  • Recommended for text-mode: 233 MHz G3 or better, 128MiB RAM.
  • Recommended for graphical: 400 MHz G3 or better, 256MiB RAM.
5.1.1.1.1. Hard Disk Space Requirements
The disk space requirements listed below represent the disk space taken up by Fedora Core 5 after installation is complete. However, additional disk space is required during installation to support the installation environment. This additional disk space corresponds to the size of /Fedora/base/stage2.img (on Installtion Disc 1) plus the size of the files in /var/lib/rpm 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 an "everything" installation. The complete packages can occupy over 9 GB of disk space.
Additional space is also required for any user data, and at least 5% free space should be maintained for proper system operation.
5.1.1.2. The Apple keyboard
The Option key on Apple systems is equivalent to the Alt key on the PC. Where documentation and the installer refer to the Alt key, use the Option key. For some key combinations you may need to use the Option key in conjunction with the Fn key, such as Option - Fn - F3 to switch to virtual terminal tty3.
5.1.1.3. PPC Installation Notes
Fedora Core Installation Disc 1 is bootable on supported hardware. In addition, a bootable CD image appears in the images/ directory of this disc. These images will behave differently according to your system hardware:
  • Apple Macintosh
    The bootloader should automatically boot the appropriate 32-bit or 64-bit installer.
    The default gnome-power-manager package includes power management support, including sleep and backlight level management. Users with more complex requirements can use the apmud package in Fedora Extras. Following installation, you can install apmud with the following command:
    • su -c 'yum install apmud'
      
  • 64-bit IBM eServer pSeries (POWER4/POWER5)
    After using OpenFirmware to boot the CD, the bootloader (yaboot) should automatically boot the 64-bit installer.
  • 32-bit CHRP (IBM RS/6000 and others)
    After using OpenFirmware to boot the CD, select the linux32 boot image at the boot: prompt to start the 32-bit installer. Otherwise, the 64-bit installer starts, which does not work.
  • Genesi Pegasos II
    At the time of writing, firmware with full support for ISO9660 file systems is not yet released for the Pegasos. However, you can use the network boot image. At the OpenFirmware prompt, enter the command:
    • boot cd: /images/netboot/ppc32.img
      
    You must also configure OpenFirmware on the Pegasos manually to make the installed Fedora Core system bootable. To do this, set the boot-device and boot-file environment variables appropriately.
  • Network booting
    You can find combined images containing the installer kernel and ramdisk in the images/netboot/ directory of the installation tree. These are intended for network booting with TFTP, but can be used in many ways.
    yaboot supports TFTP booting for IBM eServer pSeries and Apple Macintosh. The Fedora Project encourages the use of yaboot over the netboot images.
