                   "OFF" to "ON" .  
                   
                   Note: The Boot Block jumper is located near the PCI-X Slot.

                   Boot Block (SW4) jumper's pin 1 position for normal operation; pin 1 is on "OFF".

                   Boot Block (SW4) jumper's pin 1 position for Boot Block Recovery; move pin 1 to 
                   "ON".			       
                                  ___

		   the recovery process proceeds.  When the recovery is complete
		   the system will shut down.

              2.7  After the shut down, remove AC power from the system.

              2.8  Remove the top cover from the system.

              2.9  Move the Boot Block jumper (SW4) back its original location
                   for normal operation covering pins 1 and 2.

              2.10 Replace the top cover and remove the "IBM x3400/x3500 System 
                   BIOS Crisis Recovery Diskette" from the fixed floppy diskette
