HP Integrity rx7620 Server - User Service Guide, Sixth Edition

Booting the Microsoft Windows Operating System
You can boot the Windows™ Server 2003 operating system on an HP Integrity server by using
the EFI Boot Manager to select the appropriate Windows item from the boot options list.
For details on shutting down the Windows operating system, see “Shutting Down Microsoft
Windows” (page 215).
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:
