  10  * DESCRIPTION
  11  *   Do not mess with this, unless you know what you are doing.
  12  *   The data lengths and types are critical.

  14  * HISTORY
  15  *   October 7, 1996 - [aem] Andrew E. Mileski
  16  *   This struct was shamelessly stolen from the MGA DDK.
  17  *   It has been reformatted, and the data types changed.
