User Service Guide, Third Edition - HP Integrity rx4640 Server

On a Red Hat Enterprise Linux boot device EFI System Partition, the full paths to the loader
and configuration files are: \EFI\redhat\elilo.efi and \EFI\redhat\elilo.conf
After choosing the file system for the boot device (for example, fs0:) you can initiate the
Linux loader from the EFI Shell prompt by entering the full path for the ELILO.EFI loader.
By default, the ELILO.EFI loader boots Linux using the kernel image and parameters specified
by the default entry in the elilo.conf file on the EFI System Partition for the boot device.
To interact with the ELILO.EFI loader, interrupt the boot process (for example, enter a space)
at the ELILO boot prompt. To exit the ELILO.EFI loader, use the exit command.
Booting Red Hat Enterprise Linux From the EFI Shell
To boot Red Hat Enterprise Linux from the EFI Shell, follow these steps:
1. Access the EFI Shell.
From the system console, choose EFI Shell from the EFI Boot Manager menu.
2. Access the EFI System Partition for the Red Hat Enterprise Linux boot device.
To list the file systems that are known and mapped, use the map EFI Shell command (fs0,
fs1, and so on).
To choose a file system to use, enter its mapped name followed by a colon (:). For example,
to operate with the boot device that is mapped as fs3, enter fs3: at the EFI Shell prompt.
3. To launch the ELILO.EFI loader, enter ELILO at the EFI Shell command prompt.
If needed, you can specify the loader's full path by entering \EFI\redhat\elilo at the
EFI Shell command prompt.
4. Allow the ELILO.EFI loader to proceed with booting the Red Hat Enterprise Linux kernel.
By default, the ELILO.EFI loader boots the kernel image and options specified by the
default item in the elilo.conf file.
To interact with the ELILO.EFI loader, interrupt the boot process (for example, enter a
space) at the ELILO boot prompt. To exit the loader use the exit command.
Booting the SuSE Linux Enterprise Server Operating System
You can boot the SuSE Linux Enterprise Server 10 operating system on HP Integrity servers
using either of these methods:
• Choose a SuSE Linux Enterprise Server entry from the EFI Boot Manager menu.
To load the SuSE Linux Enterprise Server operating system at the EFI Boot Manager menu,
choose its entry from the list of boot options.
Choosing a Linux entry from the boot options list boots the operating system using
ELILO.EFI loader and the elilo.conf file.
• Initiate the ELILO.EFI Linux loader from the EFI Shell. For details, see “Booting SuSE Linux
Enterprise Server From the EFI Shell” (page 131).
On a SuSE Linux Enterprise Server boot device EFI System Partition, the full paths to the

Linux loader from the EFI Shell prompt by entering the full path for the ELILO.EFI loader.
By default, the ELILO.EFI loader boots Linux using the kernel image and parameters specified
