This document is part of a series of reports describing the design decisions made in porting the Chorus Operating System to the Hewlett-Packard 9000 Series 800 workstation. This document presents an overview of the project, and outlines the other reports in the series and the relationships between them. This research was supported by the Hewlett-Packard Company, Chorus Syst`emes, and the Oregon Advanced Computing Institute (OACIS). 1 Introduction This document is part of a series of reports describing the rationale, goals, technical and organizational issues that arose in porting the Chorus operating system to the Hewlett-Packard 9000/834 workstation (the 9000/834 workstation uses the Precision Architecture RISC 1.0 (PA-RISC) processor) . This document presents an overview of the project and outlines the ther reports that are available in the series. The series of reports is intended for people interested in porting Chorus or interested in gaining a better understanding of the interaction between the PA-RISC architecture and the machine dependent (and independent) layers of a micro-kernel operating system. The PA-Chorus project began in October 1990 with several goals. The members of the project had not previously performed an operating system port and therefore, one of the main objectives in undertaking the port was educational: we wanted to gain some general experience with lowlevel operating system code, and modern architectures. More specific goals of the port were to understand the interaction between micro-kernel operating system design and the HP PA-RISC architecture, and as a side-effect, to produce the infrastructure necessary to support distributed operating system research at Oregon Graduate Institute. An additional goal was to be able to offer a stable PA-...
