Booting the Operating System
Booting and Shutting Down Linux
Appendix B
165
From the system console, choose the
EFI Shell
entry from the EFI Boot Manager menu to access the
shell.
Step 2.
Access the EFI System Partition for the Red Hat Enterprise Linux boot device.
Use the
map
EFI Shell command to list the file systems (
fs0
,
fs1
, and so on) that are known and
mapped.
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.
Step 3.
Enter
ELILO
at the EFI Shell command prompt to launch the
ELILO.EFI
loader.
If needed, you can specify the loader’s full path by entering
\EFI\redhat\elilo
at the EFI Shell
command prompt.
Step 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, type 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. Refer to “Booting SuSE Linux Enterprise Server
from the EFI Shell” on page 165 for details.
On a SuSE Linux Enterprise Server boot device EFI System Partition, the full paths to the loader and
configuration files are:
\efi\SuSE\elilo.efi
\efi\SuSE\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, type a space) at the
ELILO
boot
prompt. To exit the
ELILO.EFI
loader, use the
exit
command.
Booting SuSE Linux Enterprise Server from the EFI Shell
Use this procedure to boot SuSE Linux Enterprise Server 10 from the EFI Shell.
Step 1.
Access the EFI Shell.
