 TEXT:                                                                          
 Note: This tip does not apply to Server 320 (8640 Models xYx)                  
       Which have Dual Pentium processor sockets.                               
                                                                                
 Server 300 (8640) systems are manufactured in two basic models:                
                                                                                
 Models xNx have the 486-DX2 33/66 system board, FRU P/N71G0033.                
 Models xPx have the 60 MHZ Pentium system board, FRU P/N71G0747                
                                                                                
 Both types of system board FRU's are supplied WITHOUT the                      
 processor chip, which is a separate FRU part number.                           
                                                                                
 Note:  Use care when changing the Flash/BIOS version of the                    
        Server 300.  It is possible to install the 486 system                   
        board BIOS on the Pentium system board, and Vice-versa.                 
        If this happens the system board will hang immediately                  
        and the diskette drive will be inoperable, preventing                   
        the installation of the correct BIOS..  Replacement of                  
        the system board or BIOS module will be required to fix                 
        the system.
