 118        help
 119          On some platforms, there is currently no way for the boot loader
 120          to pass arguments to the kernel. For these, you should supply some
 121          command-line options at build time by entering them here.  At a
 122          minimum, you should specify the memory size and the root device
 123          (e.g., mem=64M root=/dev/nfs).

 141        ---help---
 142          This allows you to specify the maximum number of CPUs which this
 143          kernel will support.  The maximum supported value is 6 and the
 144          minimum value which makes sense is 2.
 145
 146          This is purely to save memory - each supported CPU adds
 147          approximately eight kilobytes to the kernel image.
