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

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

  36           ECKD devices are the most commonly used devices. You should enable
  37           this option unless you are very sure to have no ECKD device.

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

  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.
