VMS Upgrade and Installation Supplement: VAX–11/780, 785

This document is a VMS Upgrade and Installation Supplement specifically for VAX-11/780 and VAX-11/785 computers, published in June 1990 for VMS Version 5.4. It is intended to be used in conjunction with the main VMS Upgrade and Installation Manual, providing computer-specific details.

The supplement covers essential procedures for system management on these VAX models, including:

1. Console Subsystem (Chapter 1): Describes the console terminal, control panel (indicator lights, switches), console diskette drive, and console command language (e.g., BOOT, DEPOSIT, HALT) for system interaction.
2. VMS Installation (Chapter 2): Provides guidance on determining device names, turning on the system, booting standalone BACKUP (a multi-diskette process), and booting the newly installed system disk (from local or HSC drives).
3. Startup and Shutdown Procedures (Chapter 3): Details various methods for booting the VMS operating system (from local or HSC drives, different directories, and using conversational boot procedures like DEFGEN.CMD), the VMS boot process, troubleshooting boot failures, and performing orderly or emergency system shutdowns.
4. Backup Procedures (Chapter 4): Explains how to use Standalone BACKUP to create and restore system disk backups, including its installation on system disks or floppy diskettes, and backing up the console RX01 diskette.
5. Multiport (Shared) Memory Units (Appendix A): Offers instructions for initializing and configuring shared memory units using SYSGEN commands.

In essence, it's a technical guide for system administrators managing VMS installations, upgrades, and fundamental operations on the VAX-11/780 and VAX-11/785 systems.
