Problems in V1.0 VMB Firmware & V1.3 CPU Firmware

This document provides step-by-step instructions for performing a Field Change Order (FCO) on VAXft 810 systems. The procedure is necessary to replace existing flash ROMs on the I/O ATM module (KD560-AA) with new versions, specifically V1.1 for the VMB firmware and V1.4 for the CPU firmware. These updates correct several known deficiencies, including issues with terminal/ELN sessions, zone booting, diagnostic failures with certain memory configurations, and missing commands in terminal duplex mode. The document details safety precautions, required tools, component identification, installation procedures for Zone A and Zone B, and verification steps to ensure the system is operational after the upgrade.
