| Installation of a new LGA gate array will allow lower address bits (1,0)     |
| to be passed on to the XMI.  This FCO will replace the field spares with     |
| revision "E*".                                                               |

	FIELD INSTALLATION
	-------------------


	1.  Inspect the specified spares kit and order EQ-01686-01
	    Rev "E8", as required, to ensure that the module will 
	    allow longword aligned addressing on the XMI.


	2.  Place the new module in the kit and return the old module,
	    labeled as "Down Rev", in the appropriate packing container.
