Executive Summary

This document outlines the minimum hardware & software requirements for parallel port devices to obtain "Plug & Play" support under Chicago. "Plug & Play" (in this document) is defined as the ability to attach an I/O device to a host, and enable the host to determine that the device has been added, identify it, and either automatically install the necessary device drivers or prompt the user for a diskette containing them. This document is not intended to provide a complete, detailed description of how an operating system will internally accomplish this, but rather to define the necessary hardware/software requirements.
