 9546 760E and 760ED models referenced in the FEATURES section                  
 of this ECA may intermittently lockup during POST if they are                  
 installed in the 3547 SlectaDock I.  The lockup condition                      
 occurs during POST Check Point 40, the screen is blank                         
 except for a cursor in the upper left corner. The type of                      
 operating system is not a factor, because the failure occurs                   
 before it is loaded.                                                           
                                                                                
 A new "SelectaDock I" system board has been released to correct                
 this condition.  The new system board is FRU P/N39H7452.  If                   
 the old FRU, P/N39H7422, is ordered it will automatically                      
 substitute to the new FRU number.
