Systems Fail to Autoboot RA70 During Power Up

This Field Change Order (KA650-F001-DAS) provides instructions for resolving issues where MicroVAX 3500/3600 and VAXstation 3200/3500 systems fail to autoboot RA70 or RA90 drives. It also addresses incompatibilities with Ultrix 3.0, failures of B/100 XQA0 commands, and support for older CPU board revisions (B-F) and the KXJ11 option. The document includes detailed installation procedures, emphasizing the use of electrostatic discharge (ESD) protection, and specifies that CPU board kits (EQ-01550-02 for multiuser, EQ-01550-03 for single user) are not interchangeable.
