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

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

        depends on DASD

          Enable this option if you want to see profiling information
          in /proc/dasd/statistics.

        depends on DASD
        help
          ECKD devices are the most commonly used devices. You should enable
          this option unless you are very sure to have no ECKD device.

        depends on DASD
        help
          Select this option to be able to access FBA devices. It is safe to
          say "Y".

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

config DASD_EER
        bool "Extended error reporting (EER)"
        depends on DASD
        help
          This driver provides a character device interface to the
          DASD extended error reporting. This is only needed if you want to
          use applications written for the EER facility.
