  10           Select this option if you want to use your expanded storage on S/390
  11           or zSeries as a disk.  This is useful as a _fast_ swap device if you
  12           want to access more than 2G of memory when running in 31 bit mode.
  13           This option is also available as a module which will be called
  14           xpram.  If unsure, say "N".
