7. Hardware Architecture Specific Notes

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

7.1. PPC Specifics for Fedora

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

7.1.1. PPC Hardware Requirements

This section lists the minimum PowerPC (PPC) hardware needed to install Fedora Core 4.

  • Minimum: PowerPC G3 / POWER4

  • Fedora Core 5 supports only the “New World” generation of Apple Power Macintosh, shipped circa 1999 onwards.

  • Fedora Core also supports IBM eServer pSeries, IBM RS/6000 and Genesi Pegasos II machines.

  • Recommended for text-mode: 233 MHz G3 or better, 64MiB RAM.

  • Recommended for graphical: 400 MHz G3 or better, 128MiB RAM.

7.1.2. PPC Installation Notes

  • The DVD or first CD of the installation set of Fedora Core is set to be bootable on supported hardware. In addition, bootable CD images can be found in the images/ directory of the DVD or first CD. These images behave differently depending on the hardware:

  • Apple Macintosh

    • The bootloader should automatically boot the appropriate 32-bit or 64-bit installer. Power management support, including sleep and backlight level management, is present in the apmud package, which is in Fedora Extras. Fedora Extras for Fedora Core is configured by default for yum. Following installation, apmud can be installed by running 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 is started, 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, the network boot image can be used. At the OpenFirmware prompt, enter the command:

      boot cd: /images/netboot/ppc32.img
      
    • You will also need to configure OpenFirmware on the Pegasos manually to make the installed Fedora Core system bootable. To do this, you need to set the boot-device and boot-file environment variables appropriately.

  • Network booting

    • There are combined images containing the installer kernel and ramdisk in the images/netboot/ directory of the install 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 use of yaboot is encouraged over the netboot images.

7.2. x86 Specifics for Fedora

This section covers any specific information you may need to know about Fedora Core and the x86 hardware platform.

7.2.1. x86 Hardware Requirements

The following information represents the minimum hardware requirements necessary to successfully install Fedora Core 5 test2.

The compatibility/availability of other hardware components (such as video and network cards) may be required for specific installation modes and/or post-installation usage.

7.2.1.1. CPU Requirements

This section lists the CPU specifications required by Fedora Core 5 test2.

The following CPU specifications are stated in terms of Intel processors. Other processors (notably, offerings from AMD, Cyrix, and VIA) that are compatible with and equivalent to the following Intel processors may also be used with Fedora Core.

  • Minimum: Pentium-class — Fedora Core 5 test2 is optimized for Pentium 4 CPUs, but also supports earlier CPUs (such as Pentium, Pentium Pro, Pentium II, Pentium III, and including AMD and VIA variants). This approach has been taken because Pentium-class optimizations actually result in reduced performance for non-Pentium-class processors, and Pentium 4 scheduling is sufficiently different (while making up the bulk of today's processors) to warrant this change.

  • Recommended for text-mode: 200 MHz Pentium-class or better

  • Recommended for graphical: 400 MHz Pentium II or better

  • AMD64 processors (both Athlon64 and Opteron)

  • Intel processors with Intel Extended Memory 64 Technology (Intel EM64T)

7.2.1.1.1. Memory Requirements

This section lists the memory required to install Fedora Core 5 test2.

This list is for 32-bit x86 systems:

  • Minimum for text-mode: 64MB

  • Minimum for graphical: 192MB

  • Recommended for graphical: 256MB

7.2.1.2. x86 Installation Notes

Installer package screen selection interface is being redesigned in the Fedora development version. Fedora Core 5 test2 does not provide a option to select the installation type such as Personal Desktop, Workstation, Server and custom.

7.3. x86_64 Specifics for Fedora

This section covers any specific information you may need to know about Fedora Core and the x86_64 hardware platform.

7.3.1. x86_64 Hardware Requirements

The following information represents the minimum hardware requirements necessary to successfully install Fedora Core 5 test2.

The compatibility/availability of other hardware components (such as video and network cards) may be required for specific installation modes and/or post-installation usage.

7.3.1.1. Memory Requirements

This section lists the memory required to install Fedora Core 5 test2.

This list is for 64-bit x86_64 systems:

  • Minimum for text-mode: 128MB

  • Minimum for graphical: 256MB

  • Recommended for graphical: 512MB

7.3.1.2. x86_64 Installation Notes

Nothing to note.
