+        Say Y if you need to force the assumption that CPEI can be re-targetted to
+        any cpu in the system. This hint is available via ACPI 3.0 specifications.
+        Tiger4 systems are capable of re-directing CPEI to any CPU other than BSP.
+        This option it useful to enable this feature on older BIOS's as well.
+        You can also enable this by using boot command line option force_cpei=1.
