OpenBoot command reference

This manual describes version 2.x OpenBoot firmware that is part of the boot PROM in Sun systems. Written for users who want to use the OpenBoot firmware to configure and debug their systems, this manual contains information on how to use the OpenBoot firmware to perform tasks such as booting the operating system, running diagnostics, modifying system start-up configuration parameters, loading and executing programs, and troubleshooting. It also describes the commands of the OpenBoot Forth interpreter.
Topics include an overview of the user interface; booting and testing your OpenBoot firmware system; setting NVRAM configuration parameters; loading and executing programs from various sources; and debugging with the disassembler, the Forth source-level debugger, and setting breakpoints.
Appendices include setting up a TIP connection using serial ports, building a bootable floppy disk, a list of unsupported commands from earlier OpenBoot systems with workarounds, troubleshooting information, and a Forth word reference.
