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 slightly depending on your hardware):

1. Boot the Itanium system and choose Boot option maintenance menu from the
EFI Boot Manager 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 5, 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 configuration file instead.
7. Answer Yes to the Save changes to NVRAM prompt. This returns you to the
EFI Boot Maintenance Manager menu.
8. Next, you want to make the Red Hat Enterprise Linux 5 menu item the
default. A list of boot options appears. Move the Red Hat Enterprise Linux 5
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 by
selecting it and pressing the d key. After changing the boot order, choose
Save changes to NVRAM. Choose Exit to return to the Main Menu.
9. Optionally, you can change the boot timeout value by choosing Set Auto
Boot TimeOut => Set Timeout Value from the Main Menu.
10. Return to the EFI Boot Manager by selecting Exit.
