Abstract

A burn-in system is described which provides a means of stress testing the mother board and circuit cards for a Personal Computer (PC) to significantly improve the reliability of these machines. The burn-in system is designed to burn-in 4 different cards: 2 planars, a Processor card, and a Co-Processor card. To minimize the development resources required, the hardware and software architecture are designed to allow a significant portion of the hardware and software to be common between the different burn-in test fixtures, as shown in Figs. 1 and 2. The characteristics of the architecture that are standardized are: 1) Bus - Defined address ranges for 1.1) Location of application code 1.2) I/O registers 1.3) Async port 1.
