Migration to CHARON-VAX for Linux

Introduction

This section describes how to migrate your VAX system to CHARON-VAX. We will use a sample MicroVAX 3600 system to demonstrate the migration procedure. The process is similar for all CHARON-VAX models.

If CHARON-VAX based virtual system needs to be created from scratch, refer to this Application Note describing how to find proper Qbus addresses and Vectors for each virtul device.

Collecting information about the source VAX system

The first step is to determine the exact configuration of your VAX hardware in order to create the CHARON-VAX configuration file.

Turn on your source VAX system. At the ">>>" prompt, issue "show qbus" and "show device" commands:
