O sistema operacional MINIX é uma nova implementação do sistema UNIX, versão 7, feito para fins didáticos. Ele está formado por uma coleção de processos, estruturados em 4 niveis: administração de processos, processos básicos do sistema, processos servidores de memória e arquivos, e processos usuários. A presente dissertação descreve o transporte do sistema MINIX, do microcomputador IBM PC XT para o computador CYGNUS do laboratório de Sistema de Computação do Departamento de Engenharia Elétrica da PUC/RJ, o qual possui uma arquitetura baseada em processadores da linha Motorola (68010 e 68020). O trabalho do transporte, constituiu em adaptar o hardware do CYGNUS para receber o sistema operacional MINIX, reprojetar o MINIX para o hardware do CYGNUS, e transportar o MINIX em forma completa, para seu novo ambiente de execução. The MINIX operating System is a new implementation of the UNIX operating system version 7, designed for didactic purposes. It is arranged as a collection of processes, structured in 4 levels: process management, system basic processes, memory and file server processes, and user processes. This work describes the transport of the MINIX system from the IBM PC XT microcomputer to te CYGNUS computer, which was developed in the Computer System Laboratory of the Electrical Engineering Department of PUC/RJ, with an architecture based on Motorola processors (68010 and 68020). The task of transporting the system, consisted in adjusting the CYCNUS hardware to accept the MINIX, redesigning the MINIX for the CYGNUS hardware, and finaly, in transporting the MINIX in its complete form to its new execution environment.
