           This allows you to specify the maximum number of CPUs which this
-          kernel will support.  The maximum supported value is 4096 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
           approximately eight kilobytes to the kernel image.
