+  \textbf{Description}: Disables \texttt{PKG\_CST\_CONFIG\_CONTROL} (\texttt{0xE2})
+  MSR modification in XNU kernel, commonly causing early kernel panic, when it is
+  locked from writing (XCPM power management).

+  \emph{Note}: This option should avoided whenever possible. Modern firmwares provide
