1214: error accessing EMS overlay cache 
------------------------------------------------------------------------------

  This message indicates that an error has occurred while the Blinker
  overlay manager is accessing EMS for the storage and / or retrieval of
  overlays in the overlay cache. If the problem persists then disable
  the BLINKER CACHE EMS command in the link script file.

  If this fixes the problem then it is possible that you have a TSR or
  device driver working in the background which is manipulating EMS
  directly in a non-standard manner. Try removing all TSRs and device
  drivers from the system except for the EMS driver, and test if the
  problem still occurs . If it does then please contact Blinker
  technical support with your Blinker serial number, your system
  configuration and a description of the problem.
