NOTE: In some versions of EFI, the Boot Configuration menu is listed as the Boot Option
Maintenance Menu.
To manage the boot options list for each system use the EFI Shell, the EFI Boot Configuration
menu, or OS utilities.
At the EFI Shell, the bcfg command supports listing and managing the boot options list for
all OSs except Microsoft Windows. On HP Integrity systems with Windows installed the
\MSUtil\nvrboot.efi utility is provided for managing Windows boot options from the
EFI Shell. On HP Integrity systems with OpenVMS installed, the \efi\vms\vms_bcfg.efi
and \efi\vms\vms_show utilities are provided for managing OpenVMS boot options.
The EFI Boot Configuration menu provides the Add a Boot Option, Delete Boot Option(s),
and Change Boot Order menu items. (If you must add an EFI Shell entry to the boot options
list, use this method.)
To save and restore boot options, use the EFI Shell variable command. The variable
-save file command saves the contents of the boot options list to the specified file on an
EFI disk partition. The variable -restore file command restores the boot options list
from the specified file that was previously saved. Details also are available by entering help
variable at the EFI Shell.
OS utilities for managing the boot options list include the HP-UX setboot command and
the HP OpenVMS @SYS$MANAGER:BOOT_OPTIONS.COM command.
The OpenVMS I64 installation and upgrade procedures assist you in setting up and validating
a boot option for your system disk. HP recommends that you allow the procedure to do
this. Alternatively, you can use the @SYS$MANAGER:BOOT_OPTIONS.COM command (also
referred to as the OpenVMS I64 Boot Manager utility) to manage boot options for your
system disk. The OpenVMS I64 Boot Manager (BOOT_OPTIONS.COM) utility is a menu-based
utility and is easier to use than EFI. To configure OpenVMS I64 booting on Fibre Channel
devices, you must use the OpenVMS I64 Boot Manager utility (BOOT_OPTIONS.COM). For
more information on this utility and other restrictions, refer to the HP OpenVMS for Integrity
Servers Upgrade and Installation Manual.

List” (page 134).

• Hyper-Threading nPartitions that have dual-core Intel® Itanium® processors can support
Hyper-Threading. Hyper-Threading provides the ability for processors to create a second
virtual core that allows additional efficiencies of processing. For example, a dual-core
processor with Hyper-Threading active can simultaneously run four threads.
The EFI Shell cpuconfig command can enable and disable Hyper-Threading for an
nPartition whose processors support it. Recent releases of the nPartition Commands and
Partition Manager also support Hyper-Threading.
