22 Chapter 4. Installing Red Hat Enterprise Linux
4.5.1. What If the IDE CD-ROM Was Not Found?
If you have an IDE (ATAPI) CD-ROM on an x86, AMD64, or Intel® EM64T system, but the installa-
tion program fails to find your IDE (ATAPI) CD-ROM and asks you what type of CD-ROM drive you
have, try the following boot command. Restart the installation, and at the
boot:
prompt enter
linux
hd X =cdrom
. Replace the
X
with one of the following letters, depending on the interface the unit is
connected to, and whether it is configured as master or slave (also known as primary and secondary):
• a
— first IDE controller, master
•
b
— first IDE controller, slave
• c
— second IDE controller, master
• d
— second IDE controller, slave
If you have a third and/or fourth controller, continue assigning letters in alphabetical order, going from
controller to controller, and master to slave.
4.6. Installing from a Hard Drive
Note
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 disk 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.
Verifying that the ISO images are intact before you attempt an installation will help to avoid problems
that are often encountered during a hard drive installation. 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 server as the ISO images.
Note
ISO images have an md5sum embedded in them. To test the checksum integrity of an ISO image, at
the installation boot prompt, type:
linux mediacheck
Itanium users should use the
elilo linux mediacheck
command.
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.
