PROBLEM: Correctable ECC errors in the last block of a read operation 
does not report "SUCCESS" in the end packet, resulting in an improper 
"FORCED ERROR" indication.

This will change the M7164 Micro Processor Module to the following 
Revisions: For "B" etch revision -- "D1"; for "C" etch revision -- 
"D2."  NOTE: This FCO incorporates ECO #M7164-CX005. The KDA50 top 
level revision will be changed to "D1." 
QUICK CHECK:  If E101-E106 contain the following PROMs: 23-078F6, 
23-079F6, 23-080F6, 23-081F6, 23-082F6, 23-083F6, this FCO is 
required.
This revised FCO supersedes the original release dated 4 March 1986.  
It has been revised to reflect a change in the LARS form.
