          Appeal No. 2002-1319                                      Page 11           
          Application No. 08/974,971                                                  


          in hardware with either pull-up or pull-down resistors (not                 
          shown) to provide any of the sizes shown in Table LXVIII.  From             
          this disclosure of DeRoo, we find that sizes of the boot block              
          sector are configured in hardware using pull-up or pull-down                
          resistors.                                                                  
               DeRoo further discloses (col. 88, lines 1-5) that “[t]hus,             
          as described, the HUI 700 can be configured to emulate boot block           
          protection to enable memory device such as the common memory                
          device 704 which do not have built-in boot block protection                 
          capability to be used for storage of the boot block protected               
          code non-volatile sector.”  Although DeRoo discloses that memory            
          704 does not have built-in boot block protection, and that HUI              
          700 emulates boot block protection, we find from all of the                 
          teachings of DeRoo provides boot block protection, irrespective             
          of whether it is emulated.  Moreover, DeRoo discloses (col. 88,             
          lines 10-15) that the protected boot block range should start on            
          a 1 kilobyte memory boundary and finish at the top of the memory            
          as shown in figure 27.  The size, as defined in Table LXVIII, and           
          therefore the starting address of the protected range, can be               
          determined from the hardware configuration register HUICFG_[0:7].           
          The remaining memory space is used for SCP (system control                  
          processor) non-volatile areas and BIOS.
