   6           Some PReP systems have residual data passed to the kernel by the
   7           firmware.  This allows detection of memory size, devices present and
   8           other useful pieces of information.  Sometimes this information is
   9           not present or incorrect, in which case it could lead to the machine
  10           behaving incorrectly.  If this happens, either disable PREP_RESIDUAL
  11           or pass the 'noresidual' option to the kernel.

  13           If you are running a PReP system, say Y here, otherwise say N.

  18         help
  19           Enabling this option will create a /proc/residual file which allows
  20           you to get at the residual data on PReP systems.  You will need a tool
  21           (lsresidual) to parse it.  If you aren't on a PReP system, you don't
  22           want this.
