FCO DRB32-0004, Corrects "hang" condition and adds a Word Counter.

This Field Change Order (FCO DRB32-0004) addresses two issues affecting DRB32-W options that utilize the T1023-00 module on VAXBI bus systems. It corrects a "hang" condition that occurs during data transfer, which previously necessitated a system power reset, and adds a missing Word Counter functionality. The solution involves replacing the T1023-00 module with the T1023-YA module (part of EQ-01570-01). The FCO outlines detailed installation procedures, including system shutdown, electrostatic discharge (ESD) precautions, physical module replacement, system power-up, and diagnostic testing using EVDRI version 4.1 or later. Additionally, it requires updating system software with V3.0 UQWDRIVER savesets (EQ-01570-02) and performing a specific code modification to activate the Word Counter. Instructions vary for different VAX system configurations, and relevant manuals are to be left with the customer.
