           Appeal No. 1997-4129                                                                     
           Application 08/237,988                                                                   

           relevant.  The Examiner does not reply to Appellants' Reply                              
           Brief and, thus, leaves it to us to sort out the arguments                               
           in the first instance.  Rather than further delay a decision                             
           on the appeal by remanding to the Examiner to address the                                
           arguments, we decide the case.                                                           
                 Hughes discloses a system comprising controller 10 and                             
           terminals 12, which are controlled by programs stored in                                 
           their respective RAMs (col. 2, lines 59-60).  "In order to                               
           operate a terminal, the terminal must know the I/O devices                               
           that are connected to it and obtain programs from the                                    
           controller to control these devices."  (Col. 3,                                          
           lines 47-50.)  The programs to control the devices are                                   
           "loadable drivers" (col. 3, lines 15-17).  Hughes discloses                              
           that during the IPL, the configuration of the list of I/O                                
           devices attached to the terminal is determined and verified                              
           by an operator.  Once the configuration is verified, "the                                
           configuration is stored in the hard totals module                                        
           [non-volatile memory] of the terminal and is transmitted to                              
           the controller where it is stored on the disk" (col. 5,                                  
           lines 24-26).  After a reset and during a subsequent program                             



                                               - 5 -
