  You need the documentation for whichever of the various PowerStorm
  graphics controllers is installed in the system.  (You might also
  want to mention which particular Alpha system.)

  I don't recognize a "20D" designation, might you mean the "PowerStorm
  4D20" module?  (The PowerStorm 3D10, 3D30, and 4D20 series modules are
  all related modules.)

  If you are not sure which graphics controller you have, and the graphics
  controller bulkhead does not indicate which controller is installed, then
  please use the console >>> SHOW commands to examine your current device
  configuration, and post the results for the graphics controller.

  The PowerStorm 4D20 has a rotary selector on the module, to allow the
  selection of various graphics resolutions settings.  Here are some of
  the (higher-end) settings for the PowerStorm 4D20:

      X     Y     V Refr H Freq     H FP      Pixel Clk
