          This allows you to specify the maximum number of CPUs which this
-         kernel will support. The maximum supported value is 256 and the
+         kernel will support. The maximum supported value is 512 and the
          minimum value which makes sense is 2.
 
          This is purely to save memory - each supported CPU adds
