Section 3.25:Booting Your Machine and Post-Installation Setup 65
This command displays the contents of the configuration file. Each stanza contains a line begin-
ning with label followed by a label name for that kernel. The label name is what you type after
elilo to boot the different kernels.
3.25.1 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 Linux to see 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):
Shell>elilo linux

3.25.2 Booting Red Hat Linux Automatically
After installing Red Hat Linux you can type elilo and any boot options at the EFI Shell prompt
each time you wish to boot your Itanium system. However, if you wish to configure your system to
boot into Red Hat Linux automatically, you need to configure the EFI Boot Manager.
To configure the EFI Boot Manager (may vary slighly depending on your hardware):
1. Boot the Itanium system and choose
Boot option maintenance menu from the EFI Boot Man-
ager menu.
2. Choose
Add a Boot Option from the Main Menu.
3. Select the system partition that is mounted as /boot/efi in Linux.
4. Select the elilo.efi file.
5. At the Enter New Description: prompt, type Red Hat Linux 7.2, or any name that
you want to appear on the EFI Boot Manager menu.
6. At the Enter Boot Option Data Type prompt, enter N for
No Boot Option if you do
not want to pass options to the ELILO boot loader. This option will work for most cases. If you
want to pass options to the boot loader, you can configure it in the /boot/efi/elilo.conf
configuration file instead.
7. Answer Yes to the Save changes to NVRAM prompt. This will return you to the EFI Boot
Maintenance Manager menu.
8. Next, you want to make the
Red Hat Linux 7.2 menu item the default. You will see a list of
boot options. Move the
Red Hat Linux 7.2 menu item up to the top of the list by selecting it with
the arrow keys and pressing the
[u] key to move it up the list. You can move items down the list
