Booting the Red Hat Linux Operating System
You can boot the Red Hat Linux operating system on HP Integrity servers using either of the methods
described in this section.
See “Shutting Down Linux” on page 197 for details on shutting down the Red Hat Linux operating system.
CAUTION ACPI Configuration for Red Hat Linux 3 Must Be “single-pci-domain”
On nPartition-capable HP Integrity servers, to boot the Red Hat Linux 3 operating system an
nPartition must have its ACPI configuration value set to single-pci-domain.
At the EFI Shell, enter the acpiconfig command with no arguments to list the current ACPI
configuration. If the acpiconfig value is not set to single-pci-domain, then Red Hat Linux
could panic; in this situation you must reconfigure acpiconfig to eliminate any bus address
conflicts and ensure all I/O slots have unique addresses.
To set the ACPI configuration for Red Hat Linux 3: at the EFI Shell enter the acpiconfig
single-pci-domain command, and then enter the reset command for the nPartition to reboot
with the proper (single-pci-domain) configuration for Red Hat Linux 3.
Use either of these methods to boot Red Hat Linux:
• Select a Red Hat Linux entry from the EFI Boot Manager menu.
To load the Red Hat Linux operating system at the EFI Boot Manager menu, select its entry from the list
of boot options.
Selecting a Linux entry from the boot options list boots the operating system using ELILO.EFI loader and
the elilo.conf file.
• Invoke the ELILO.EFI Linux loader from the EFI Shell.
See the procedure “Red Hat Linux Operating System Booting from the EFI Shell” on page 190 for details.
On a Red Hat Linux boot device EFI System Partition, the full paths to the loader and configuration files
are:
\EFI\redhat\elilo.efi
\EFI\redhat\elilo.conf
After selecting the filesystem for the boot device (for example, fs0:) you can invoke 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.
