The Fedora software exists in two parts: Fedora Core, a Linux distribution that includes base applications for desktop and server systems, and Fedora Extras, a repository of additional applications that can be added easily to a Fedora Core system.
The first step is to obtain a copy of the Fedora Core software itself.
The Fedora Core installer is a bare-bones configuration of Linux designed specifically for the installation process. Once the installer is running, it configures and installs the Fedora Core software on your system.
There are, therefore, two parts to the software: the software used to boot up the system for the installation session, and the software that is installed on your system. These may be on the same media, or they may be separated into boot media and installation media.
Before selecting the media and obtaining the software, you must determine which architecture (machine type) you are using. Fedora Core is available for three different architectures:
- i386
All Intel-compatible 32-bit systems with a standard BIOS, including all Intel 32-bit Celeron, Pentium, Centrino, and Core systems; AMD 32-bit Athlon, Duron, and Turion systems; and VIA CPUs such as the C3 and Eden processors. Older processors such as 80386, 80486, and K6 processors will also work. Fedora Core may be installed on Apple Mac systems with an Intel processor by using Appleâs Boot Camp software (included in Mac OS X 10.5 and available in beta form for Mac OS X 10.4).
- x86_64
All AMD-compatible 64-bit systems, including Opteron, Athlon 64, Duron 64, and Turion 64 systems, and Intel 64-bit Pentium 4, Xeon, and Core 2 systems. These systems can also run the i386 version but will do so in 32-bit mode.
- PPC
Systems based on the PowerPC G3/POWER4 and later PowerPC processors, including recent PPC-based Apple Macs (manufactured between 1999 and 2006), IBM eServer pSeries, and IBM RS/6000 systems.
This chapter focuses on the i386 and x86_64 platforms, but the PPC installation procedure is quite similar.
The Fedora Core installation boot software is usually started from a CD or DVD disc. Itâs also possible to boot from a USB flash disk drive if the systemâs BIOS supports it, or to boot from a network boot server using the PXE protocol. Table 1-1 outlines the boot media requirements.
Table 1-1. Boot media requirements for installing Fedora Core 6
| Media type | Media count | Size | Notes |
|---|---|---|---|
| DVD | 1 | 4.7 GB (or larger) | All of the software will fit on one disc (which serves as both the boot and installation medium), so this is usually the fastest and most convenient installation option. |
| CD | 1 | 8 MB (any CD) | A single CD or mini-CD can be used to start a network or hard disk installation. If you will be using CDs for both the boot and installation media, five 700 MB discs are required (see Table 1-2). |
| USB flash drive | 1 | 8 MB or higher | Requires a Linux system to configure the drive. Useful for network or hard disk installation. The BIOS of some systems will not permit booting from a USB flash key (beware of BIOS versions that permit booting only from a USB floppy or Zip drive). |
| PXE Server (Network Boot) | 1 | 6.5 MB | Requires an existing system to serve as the PXE server (see Lab 10.3, âPreparing Alternate Installation Mediaâ). |
Once the system has been booted, the rest of the installation software can be on a DVD, several CDs, an existing hard drive partition on the computer (or an external hard disk drive), or an FTP, NFS, or HTTP server. Table 1-2 outlines the requirements.

To create a Fedora Core CD or DVD set, you must obtain the ISO image files.
To download the entire Fedora Core distribution for installation direct from disc, use one of these two procedures:
Go to the web page http://fedora.redhat.com/Download/mirrors.html and select an HTTP or FTP site for direct download. Select the directory for the desired Fedora Core version number (6), then the directory for your machine architecture (i386, PPC, or x86_64), and then select the iso directory. You will probably not need the files containing âSRPMâ in the name. If you want the CD images, get the files containing âdisc1,â âdisc2,â and so forth in the name; to obtain the DVD image, get the file containing âDVDâ in the name.
Use BitTorrent (http://www.bittorrent.com) to obtain the files from one of the Fedora torrents listed on http://torrent.fedoraproject.org/.
Warning
Some download tools have problems with files over 2 GB in size. Most of the time, these problems affect only the download size, progress, or time-remaining displays during the download process, but some versions of the Lynx browser will not successfully download files over 2 GB. Older versions of wget also have a 2 GB limitation. If you are downloading onto a Windows system that is formatted with the FAT file system, the maximum file size may be 2 GB (FAT16) or 4 GB (FAT32).
To download only the boot disk ISO (for use with a network or hard disk installation):
Go to the web page http://fedora.redhat.com/Download/mirrors.html and select an HTTP or FTP site for direct download. Select the directory for the desired Fedora Core version number (6), then the directory for your machine architecture (i386, PPC, or x86_64), select the os directory, and then select the images directory. Download the file named boot.iso. (You can also find this file in the images directory of the Fedora Core DVD or CD disc 1).
Once you have the image files, burn them onto optical media using the CD-creator program available on the platform used for downloading. For example, on Windows you could use Nero or Roxio Easy Media Creator; on a Linux system (such as Fedora Core 4), right-click on the file and select âWrite to disc,â or use a tool such as K3B, xcdroast, or growisofs.
Warning
When burning a CD or DVD, use the ISO image file as the disc filesystem, but do not place the ISO image inside another filesystem on the disc. You will usually get the correct results if you save the ISO file to the desktop and then double-click on it.
To verify that the disk was created correctly, open it after you burn it: you should see several files and directories. If you see a single file with a .iso extension, the disc was not created correctly.
Depending on the speed of your Internet connection, it may be faster and cheaper to purchase a set of Fedora discs than to download the software. A list of online Fedora Core vendors is available at http://fedoraproject.org/wiki/Distribution/OnlineVendors, and a list of local retailers carrying Fedora Core is at http://fedoraproject.org/wiki/Distribution/LocalVendors.
To install Fedora Core from a FAT, ext2, or ext3 partition, simply copy the ISO image files for the DVD or CD set onto that disk partition. For example, on a Windows system with a FAT32 disk partition D:, download the DVD image file as though you were going to burn it onto a DVD but place the image file on drive D: (be sure to record the name of the directory/folder containing the images!).
Each of these tasks is most easily performed on a running Linux system; see Chapter 10 for instructions. (Similar software is available for other platforms.)
An ISO image file is an exact copy of the contents of an optical disk. The name comes from the fact that data on optical discs is stored using a standard known as ISO 9660.
Each type of boot media has a unique standard for specifying how boot data is stored. On optical discs, the El Torito standard permits the system BIOS to find the boot software. For USB disks, a standard hard disk boot sector is used. For PXE network booting, a boot protocol (bootp) server is used to identify the boot files, and a trivial file transfer protocol (TFTP) server is used to serve them to the client system.
The first piece of software that loads from the boot media is the bootloader: isolinux for optical discs, syslinux for USB flash drives, or pxelinux for PXE boot servers.
After accepting boot parameters from the user, the bootloader subsequently loads two files:
Once these files have been loaded, the kernel is executed and begins the install process.
