HP Integrity rx1620 Deployment Manual page 61

On a cell-based Integrity server, a special system ACPI flag must be properly set before the
operating system is started. When SSTK is running it always sets the ACPI mode to the
single-pci-domain or default state and sets to the Windows mode when deploying Windows.
If you are MANUALLY rebooting the server to start the Windows operating system, change the
ACPI mode to windows using hpsetacpi from SSTK environment (LinuxPE) or the acpiconfig
utility from EFI environment.
Failure to set the ACPI mode to Windows will cause Windows boot to fail.
NOTE: The SSTK 2.8 utility, bootia64.efi, automatically sets the ACPI mode back to
Windows after running SSTK if both of the following conditions are met:
• A version of Windows is installed on the system.
• The default boot option points to Windows.
Otherwise, you must set the ACPI flag manually.
