Boot Process Differences for nPartitions on HP 9000 servers and HP Integrity servers The following lists, "HP Integrity Server Booting" and "HP 9000 Server Booting", describe system boot features and differences on HP Integrity and HP 9000 servers. HP Integrity Server Booting This list describes system boot features on cell-based HP Integrity servers. • The nPartition system boot environment is the Extensible Firmware Interface (EFI): the EFI Boot Manager menu and the EFI Shell. • The autoboot process is configured by the EFI autoboot setting and the order of items in the boot options list. The boot options list can include: - First boot option: configured using the setboot -p... or parmodify -b... command. - Second boot option: configured using the setboot -h... or parmodify -s... command - Third boot option: configured using the setboot -a... or parmodify -t... command. • Each operating system has its own OS loader. - The HP-UX OS loader is HPUX.EFI, which supports hpux(1M) loader options. You can issue hpux loader commands from the HPUX> prompt. - The HP OpenVMS I64 loader is vms_loader.efi. - The Microsoft® Windows® loader is ia64ldr.efi and it is invoked only from the EFI Boot Manager. - The loader for Red Hat Enterprise Linux and SuSE Linux Enterprise Server is ELILO.EFI. You can issue ELILO loader commands from the "ELILO boot" prompt. • The EFI system boot environment includes an ACPI configuration setting that must be set properly for the OS being booted: either HP-UX, OpenVMS I64, Windows, or Linux.
