2. System Startup Modes: Information on booting the system into single-user mode, multiuser mode, and conversational mode (VAX only), including what happens in each mode and how to invoke them.
3. Processor-Specific Boot Commands: A major section outlining detailed boot commands for numerous Digital Equipment Corporation processors, including various MicroVAX, VAXstation, VAX, and DECstation models. It covers booting from the console, TK50 tape, network, local disks, and HSC disks, along with procedures for building and updating boot command files.
4. The Standalone ULTRIX Environment: A description of this diskless environment, its purpose for initial installations, and its capabilities for system management activities such as restoring and checking file systems, restoring boot blocks, and performing disk maintenance.

The manual is intended for individuals responsible for managing and maintaining ULTRIX systems and assumes familiarity with ULTRIX commands, system configuration, and editor usage.
