Appendix A

Hardware Overview

This appendix discusses general issues about hardware that is capable of supporting the Solaris OS. The discussion includes the processor, bus architectures, and memory models that are supported by the Solaris OS. Various device issues and the PROM used in Sun platforms are also covered.

Note - The material in this appendix is for informational purposes only. This information might be of use during driver debugging. However, many of these implementation details are hidden from device drivers by the Solaris DDI/DKI interfaces.

This appendix provides information on the following subjects:
