Chapter 2. Installing Red Hat Enterprise Linux 13
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.
2.4. 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
iSeries system users must remember to add boot options, as are listed in this manual for other
operating systems, by first logging into an OS/400 system as an iSeries user and then setting any
IPL parameters within their partition’s NWSD.
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.
