4.27. Itanium Systems — Booting Your Machine and Post-Installation Setup

This section describes how to boot your Itanium into Red Hat Enterprise Linux and how to set your EFI console variables so that Red Hat Enterprise Linux is automatically booted when the machine is powered on.
After you reboot your system at the end of the installation program, type the following command to boot into Red Hat Enterprise Linux:
After you type elilo, the default kernel listed in the /boot/efi/elilo.conf configuration file is loaded. (The first kernel listed in the file is the default.)
If you want to load a different kernel, type the label name of the kernel from the file /boot/efi/elilo.conf after the elilo command. For example, to load the kernel named linux, type:
elilo linux
If you do not know the names of the installed kernels, you can view the /boot/efi/elilo.conf file in EFI with the following instructions:
  1. At the Shell> prompt, change devices to the system partition (mounted as /boot/efi in Linux). For example, if fs0 is the system boot partition, type fs0: at the EFI Shell prompt.
  2. Type ls at the fs0:\> to make sure you are in the correct partition.
  3. Then type:
    type elilo.conf
    This command displays the contents of the configuration file. Each stanza contains a line beginning with label followed by a label name for that kernel. The label name is what you type after elilo to boot the different kernels.

4.27.1. Post-Installation Boot Loader Options

In addition to specifying a kernel to load, you can also enter other boot options such as single for single user mode or mem=1024M to force Red Hat Enterprise Linux to use 1024 MB of memory. To pass options to the boot loader, enter the following at the EFI Shell prompt (replace linux with the label name of the kernel you want to boot and option with the boot options you want to pass to the kernel):

elilo linux
