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

  24           Enable this option if you want to access DASDs directly utilizing
  25           S/390s channel subsystem commands. This is necessary for running
  26           natively on a single image or an LPAR.

  38         help
  39           ECKD devices are the most commonly used devices. You should enable
  40           this option unless you are very sure to have no ECKD device.

  46           Select this option to be able to access FBA devices. It is safe to
  47           say "Y".

  53           Select this option if you want to use Diagnose250 command to access
  54           Disks under VM.  If you are not running under VM or unsure what it is,
  55           say "N".

  59         depends on DASD
  60         help
  61           This driver provides a character device interface to the
  62           DASD extended error reporting. This is only needed if you want to
  63           use applications written for the EER facility.
