Details of the cpuconfig command are given below and are available by entering help
cpuconfig at the EFI Shell.
cpuconfig threads — Reports Hyper-Threading status for the nPartition
cpuconfig threads on — Enables Hyper-Threading for the nPartition. After enabling
Hyper-Threading the nPartition must be reset for Hyper-Threading to be active.
cpuconfig threads off — Disables Hyper-Threading for the nPartition. After
disabling Hyper-Threading the nPartition must be reset for Hyper-Threading to be
inactive
After enabling or disabling Hyper-Threading, the nPartition must be reset for the
Hyper-Threading change to take effect. Use the EFI Shell reset command.
Enabled means that Hyper-Threading will be active on the next reboot of the nPartition.
Active means that each processor core in the nPartition has a second virtual core that enables
simultaneously running multiple threads.
Autoboot Setting You can configure the autoboot setting for each nPartition either by using
the autoboot command at the EFI Shell, or by using the Set Auto Boot TimeOut menu item
at the EFI Boot Option Maintenance menu.
To set autoboot from HP-UX, use the setboot command.
ACPI Configuration Value—HP Integrity Server OS Boot On cell-based HP Integrity servers
you must set the proper ACPI configuration for the OS that will be booted on the nPartition.
To check the ACPI configuration value, issue the acpiconfig command with no arguments
at the EFI Shell.
To set the ACPI configuration value, issue the acpiconfig value command at the EFI Shell,
where value is either default or windows. Then reset the nPartition by issuing the reset
EFI Shell command for the setting to take effect.
The ACPI configuration settings for the supported OSes are in the following list.
HP-UX ACPI Configuration: default On cell-based HP Integrity servers, to boot or install
the HP-UX OS, you must set the ACPI configuration value for the nPartition to default.

HP OpenVMS I64 ACPI Configuration: default On cell-based HP Integrity servers, to
boot or install the HP OpenVMS I64 OS, you must set the ACPI configuration value for
the nPartition to default.
