HP Integrity rx8620 Server User Service Guide

For details on shutting down the Windows operating system, see “Shutting Down Microsoft
Windows” (page 214).
CAUTION:
ACPI Configuration for Windows Must Be “windows” On nPartition-capable HP Integrity servers,
to boot the Windows operating system 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, Windows cannot boot. In this
situation, you must reconfigure acpiconfig or booting is 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 select a Windows entry from the boot options
list. Using the ia64ldr.efi Windows loader from the EFI Shell is not recommended.
Procedure E-5 Windows Booting
From the EFI Boot Manager menu, select an item from the boot options list to boot Windows
using the selected boot option. The EFI Boot Manager is available only on HP Integrity servers.
See “ACPI Configuration for Windows Must Be “windows”” (page 209) for required configuration
details.
1. Access the EFI Boot Manager menu for the system on which you want to boot Windows.
To access the Console list, log in to the MP and enter CO. Select the nPartition console.
When accessing the console, confirm that you are at the EFI Boot Manager menu (the main
EFI menu). If at another EFI menu, select Exit from the sub-menus until you return to the
screen with the EFI Boot Manager heading.
2. At the EFI Boot Manager menu, select 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. To initiate booting using the selected boot option, press Return or Enter.
4. Once 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 see the SAC online help (enter ? at the SAC> prompt).
