nPartition Administrator's Guide, Second Edition

Refer to “Shutting Down Microsoft Windows” (page 128) for details on shutting down the
Windows OS.
CAUTION:
ACPI Configuration for Windows Must Be windows On cell-based HP Integrity servers, to boot
the Windows OS an nPartition must have its ACPI configuration value set to windows.
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 windows, then Windows cannot boot; in
this situation you must reconfigure acpiconfig or booting will be interrupted with a panic
when launching Windows.
To set the ACPI configuration for Windows: At the EFI Shell enter the acpiconfig windows
command, and then enter the reset command for the nPartition to reboot with the proper
(windows) configuration for Windows.
NOTE:
Microsoft Windows Booting on HP Integrity Servers The recommended method for booting
Windows is to use the EFI Boot Manager menu to choose a Windows entry from the boot options
list. Using the ia64ldr.efi Windows loader from the EFI Shell is not recommended.
Procedure 5-20 Windows Booting
From the EFI Boot Manager menu, choose an item from the boot options list to boot Windows
using that boot option. The EFI Boot Manager is available only on HP Integrity servers.
Refer to “ACPI Configuration for Windows Must Be windows” (page 127) for required
configuration details.
1. Access the EFI Boot Manager menu for the system on which you want to boot Windows.
Log in to the management processor and enter CO to access the Console list. Choose the
nPartition console.
When accessing the console, confirm that you are at the EFI Boot Manager menu (the main
EFI menu). If you are at another EFI menu, choose the Exit option from the submenus until
you return to the screen with the EFI Boot Manager heading.
2. At the EFI Boot Manager menu, choose an item from the boot options list.
Each item in the boot options list references a specific boot device and provides a specific
set of boot options or arguments to be used when booting the device.
3. Press Enter to initiate booting using the chosen boot option.
4. When Windows begins loading, wait for the Special Administration Console (SAC) to become
available.
The SAC interface provides a text-based administration tool that is available from the
nPartition console. For details refer to the SAC online help (type ? at the SAC> prompt).
