56 Chapter 4. Installing Red Hat Enterprise Linux
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:
Shell type elilo.conf
This command displays the contents of the configuration file. Each stanza contains a line be-
ginning with
label
followed by a label name for that kernel. The label name is what you type
after
elilo
to boot the different kernels.
4.30.1. 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 option
4.30.2. Booting Red Hat Enterprise Linux Automatically
After installing Red Hat Enterprise 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 Enterprise 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 Enterprise Linux 3
, 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 works for most cases. If you want to
pass options to the boot loader, you can configure it in the
/boot/efi/elilo.conf
configu-
ration file instead.
7. Answer
Yes
to the
Save changes to NVRAM
prompt. This returns you to the
EFI Boot
Maintenance Manager menu.

Red Hat Enterprise Linux 3
menu item the default. A list of
boot options appears. Move the
Red Hat Enterprise Linux 3
