Problem Description: 

	Sun4m machines with SuperSPARC processors with ECache 
        may print an incorrect error message when an external
	cache parity error occurs.  They will report that there 
        is an ECC Memory Error for SIMM xxxxx.  This causes 
        field service to swap out a SIMM module when the problem
        lies with the SPARC module.
	(This is ONLY for systems with SuperSPARC ECache modules).
