本节提供 Fedora 所支持的特定硬件体系的信息。
6.1. 64 位平台下(x86_64, ppc64) RPM 多体系支持
RPM supports parallel installation of
multiple architectures of the same package. A default package
listing such as rpm -qa might appear to include
duplicate packages, since the architecture is not displayed.
Instead, use the repoquery command, part of the
yum-utils package, which displays architecture
by default. To install yum-utils , run the
following command:
su -c "yum install yum-utils"
要用 rpm 列出所有软件包以及其体系，运行命令:
rpm -qa --queryformat "%{name}-%{version}-%{release}.%{arch}\n"
您可以将它添加到 /etc/rpm/macros (系统范围的设置)或 ~/.rpmmacros (用户各自的设置)。它改变默认的查询方式，以列出体系:
%_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch}
6.2. PPC 相关
本节包含 Fedora 特定于 PPC 硬件平台的信息。
6.2.1. PPC 硬件需求
6.2.1.1. 处理器及内存
Minimum CPU: PowerPC G3 / POWER3.
Fedora 9 supports only the "New World" generation of Apple Power Macintosh, shipped from circa 1999 onward.
Fedora 9 also supports IBM pSeries, IBM iSeries, IBM RS/6000, Genesi Pegasos II, and IBM Cell Broadband Engine machines.
Fedora 9 includes new hardware support for Genesi Efika, and for the Sony PlayStation 3.
文本模式推荐值: 233MHz G3 或更佳，128MiB 内存
图形模式推荐值: 400MHz G3 或更佳，256MiB 内存
6.2.1.2. 硬盘空间需求
The disk space requirements listed below represent the disk
space taken up by Fedora 9 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 Installation
Disc 1) plus the size of the files in
/var/lib/rpm on
the installed system.
实际上，这意味着，最小安装需要 90MiB 额外空间，而完全安装需要 175MiB 额外空间。所有软件包将占据 9GB 磁盘空间。
另外，记住用户数据也需要额外空间存放，为使系统正常运作，还应保留至少 5% 空闲空间。
6.2.2. 64位机上的4 KiB 页面文件
通过在Fedora Core 6上对64 64KiB页面的简短实验，PowerPC 64 内核已经换回到4KiB页面。升级过程中，安装程序会自动的重新格式化所有的交换分区。
6.2.3. Apple 键盘
Apple 系统中的 Option 键相当于 PC 中的 Alt键。安装过程中提到 Alt 键时，使用 Option 代替。有些组合键需要用 Option 键与 Fn 键组合出来，例如 Option+Fn+F3 可以切换到虚拟终端 tty3。
6.2.4. PPC 安装注记
Fedora 安装盘 1 是可以在所支持的硬件平台上启动的。另外，可以在 CD 的 images/ 目录找到一份可启动的 CD 镜像。硬件不同，它们的行为也不同:
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), 新近的 iSeries 机型. 使用 OpenFirmware 引导 CD 后，引导管理器 (
yaboot) 自动运行 64 位的安装程序。IBM "Legacy" iSeries (POWER4). 被称为 "Legacy" 的 iSeries 不使用 OpenFirmware。应当使用安装树的
images/iSeries目录中的引导镜像。32-bit CHRP (IBM RS/6000 及其他). 使用 OpenFirmware 启动 CD 后，在
boot:提示符下选择linux32镜像，引导 32 位的安装程序。否则，64 位安装程序会自动引导，而它无法运行。-
Genesi Pegasos II. 在本文档撰写时，Pegasos 完全支持 ISO9660 文件系统的固件尚未发布。但是，可以使用网络启动盘。在 OpenFirmware 提示符下，输入命令:
boot cd: /images/netboot/ppc32.img
You must also manually configure OpenFirmware on the Pegasos to make the installed Fedora system bootable. To do this, set the
boot-deviceandboot-fileenvironment variables appropriately. Genesi Efika 5200B. To run Linux correctly on the Efika, download the "Device Tree Supplement" from http://www.powerdeveloper.org/platforms/efika/devicetree and install according to the documentation therein. At the time of writing, the firmware of the Efika has bugs which prevent correct operation of the
yabootbootloader. Genesi stated that a fixed firmware would be made available by April 2007. As of November 2007, it is not yet available.-
Sony PlayStation 3. For installation on PlayStation 3, first update to firmware 1.60 or later. The "Other OS" boot loader must be installed into the flash, following the instructions at http://www.playstation.com/ps3-openplatform/manual.html. A suitable boot loader image can be found on Sony's "ADDON" CD, available from ftp://ftp.kernel.org/pub/linux/kernel/people/geoff/cell/.
Once the boot loader is installed, the PlayStation 3 should be able to boot from the Fedora install media. Type
linux64 xdriver=fbdevat the boot prompt, which will work around https://bugzilla.redhat.com/show_bug.cgi?id=370761. Please note that network installation works best with NFS, since that takes less memory than FTP or HTTP methods. Using thetextoption also reduces the amount of memory taken by the installer.For more information on Fedora and the PlayStation3 or Fedora on PowerPC in general, join the Fedora-PPC mailing list or the
#fedora-ppcchannel on FreeNode. -
网络启动. Combined images containing the installer kernel and ramdisk are located in the
images/netboot/directory of the installation tree. They are intended for network booting with TFTP, but can be used in many ways.yaboot支持用 TFTP 引导 IBM eServer pSeries 和 Apple Macintosh。Fedora 项目建议结合使用yaboot和netboot镜像。
6.2.5. PPC Specific Packages
ppc64-utils has been split out into
individual packages reflecting upstream packaging
(ps3pf-utils,
powerpc-utils,
powerpc-utils-papr). The
mkzimage command is no longer supplied, you
can use the wrapper script from kernel-bootwrapper package - eg:
wrapper -i initrd-${KERN_VERSION}.img -o zImage-${KERN_VERSION}.img vmlinuz-${KERN_VERSION}
6.3. x86 相关
本节包含 Fedora 特定于 x86 硬件平台的信息。
6.3.1. x86 硬件需求
In order to use specific features of Fedora 9 during or after installation, you may need to know details of other hardware components such as video and network cards.
6.3.1.1. 处理器及内存
下列 CPU 特性是以 Intel 处理器的方式表述的。其他处理器 (主要是来自 AMD, Cyrix 和 VIA 的那些) 如果与 Intel 处理器兼容，也可以用于 Fedora 。
Fedora 9 需要 Intel 奔腾或更高处理器，并且为奔腾 4 及更高处理器做了优化。
Recommended for text-mode: 200 MHz Pentium-class or better.
Recommended for graphical: 400 MHz Pentium II or better.

6.3.1.2. 硬盘空间需求
The disk space requirements listed below represent the disk
space taken up by Fedora 9 after the installation is complete.
However, additional disk space is required during the
installation to support the installation environment. This
additional disk space corresponds to the size of
/Fedora/base/stage2.img on Installation
Disc 1 plus the size of the files in
/var/lib/rpm on
the installed system.
实际上，这意味着，最小安装需要 90MiB 额外空间，而完全安装需要 175MiB 额外空间。所有软件包将占据 9GB 磁盘空间。
