| | Hard drive installations only work
from ext2, ext3, or FAT file systems. If you have a file system other than
those listed here, such as reiserfs, you will not be able to perform a
hard drive installation. |
Hard drive installations require the use of the ISO (or CD-ROM)
images. An ISO image is a file containing an exact copy of a CD-ROM
image. Because Red Hat Enterprise Linux has so many packages included with its distribution,
there are several ISO images available. After placing the required ISO
images (the binary Red Hat Enterprise Linux CD-ROMs) in a directory, choose to install from the
hard drive. You can then point the installation program at that directory
to perform the installation.
To prepare your system for a hard drive installation, you must set the
system up in one of the following ways:
Using a set of CD-ROMs — Create CD-ROM ISO image files from each
installation CD-ROM. For each CD-ROM, execute the following command on
a Linux system:
dd if=/dev/cdrom of=/tmp/file-name.iso |
Using ISO images — transfer these images to the system to be
installed.
Verifying that ISO images are intact before you attempt an
installation, helps to avoid problems. To verify the ISO images are
intact prior to performing an installation, use an
md5sum program (many
md5sum programs are available for various
operating systems). An md5sum program
should be available on the same Linux machine as the ISO
images.

| | The Red Hat Enterprise Linux installation program has the
ability to test the integrity of the installation media. It works with the
CD, DVD, hard drive ISO, and NFS ISO installation methods. Red Hat recommends
that you test all installation media before starting the installation
process, and before reporting any installation-related bugs (many of the
bugs reported are actually due to improperly-burned CDs). To use this test,
type the following command at the boot: prompt
(prepend with elilo for Itanium systems): |
Additionally, if a file called
RedHat/base/updates.img exists in the directory from
which you install, it is used for installation program updates. Refer to
the file install-methods.txt in the
anaconda RPM package for detailed information on the
various ways to install Red Hat Enterprise Linux, as well as how to apply the installation
program updates.
