          Appeal No. 2000-1260                                                            
          Application 08/518,852                                                          

          underway should continue in spite of the failure to properly                    
          initialize the device driver, or whether a new system boot                      
          procedure should be initiated using the LastKnownGood control set               
          (210) of the registry (107).  See Appellants’ specification page                
          10 lines 5-12.  The LastKnownGood control set (210) contains a                  
          data value that identifies a control set containing the data                    
          values that last successfully booted the computer.  See                         
          Appellants’ specification page 8 lines 31-34.  In response to a                 
          successful boot from the Default control set (209), the                         
          UpdateRegistry program (123) makes a new LastKnownGood control                  
          set (210) that is equivalent to the Default control set (209)                   
          which successfully booted the computer (105).  See Appellants’                  
          specification page 10 lines 19-23.  In this way, it is ensured                  
          that the computer (105) will successfully boot even after some                  
          configuration data in the Default control set (209) has become                  
          unusable.  See Appellants’ specification page 10 lines 30-33.                   
               Independent claims 23 and 26 present in the application are                
          reproduced as follows:                                                          
               23.  A method for configuring a computer system, the                       
          computer system having a plurality of devices and having a                      
          multiplicity of device drivers, each device driver for                          
          communicating with a device, the method comprising the computer-                
          implemented steps of:                                                           

                                            3
