SYSGEN is the procedure used to tailor and build a version of the RSX-11M or RSX-11M-PLUS operating system for a particular PDP-11 installation. The SYSGEN procedure asks questions about both the software features you wish to include in your system, and about your system's hardware configuration. SYSGEN uses that information to assemble and task build an RSX-11M or RSX-11M-PLUS operating system specifically tailored to your needs. You should read both the System Generation and Installation Guide and the Release Notes for this release of your operating system before attempting to run the SYSGEN procedure. Attempts to run SYSGEN without first consulting the documentation may yield undesired results. You should also be familiar with the features and structure of the RSX-11 operating systems before attempting to generate your own system so you will understand the consequences of choosing or omitting various system options.
