Before You Begin the Installation Process
2.1. Installation Overview
Installing Red Hat Linux Advanced Server on an Itanium system is different from installing Red
Hat Linux Advanced Server on an x86 machine. In general, the sequence of steps to a successful
installation are the following:
1. Boot into the Extensible Firmware Interface (EFI) Shell.
2. If you can not boot from the CD-ROM and the system has an LS-120 or LS-240 drive, make an
LS-120 diskette from the boot image file provided with Red Hat Linux Advanced Server.
3. Using the EFI Shell and the ELILO boot loader, load and run the kernel, and boot into the Red
Hat Linux Advanced Server installation program.
2.1.1. Disk Space Requirements
Before you begin the installation, be aware that you will need certain amounts of free disk space to
install Red Hat Linux Advanced Server.
At minimum, you will need 512 MB of RAM and 1 GB of free hard disk space to install.
•
You should have 1024 MB of RAM and 4.2 GB or more of free hard disk space on your machine
•
for a full installation.
Depending upon what type of installation you are performing, you may need an LS-120 diskette.
2.2. The EFI Shell
Before you start to install Red Hat Linux Advanced Server on an Itanium, you will need a basic
understanding of the EFI Shell, what it does, and the information it can provide.
The EFI Shell is a console interface used to launch applications (such as the Red Hat Linux Advanced
Server installation program), load EFI protocols and device drivers, and execute simple scripts. It is
similar to a DOS console and can access media that is FAT16 (vfat) or FAT32 formatted.
The EFI Shell also contains common utilities that can be used on the EFI system partition. These
utilities include
edit
at the EFI Shell prompt.

2.2.1. EFI Device Names
The
command can be used to list all devices and file systems that EFI can recognize. When your
map
Itanium system boots into the EFI shell, it probes your system in the following order:
1. LS-120 or LS-240 drive (if it contains media)
