Chapter 2. The Hardware Environment

CHAPTER OBJECTIVES

  • Hardware Basic

  • Buses and Windows 2000

  • Hints for Working with Hardware

  • Summary

It is a fact of life that device drivers must interact with "real" hardware. Traditionally, first-generation device drivers were written as unit test code by the hardware designers. These early drivers were then passed to hardware-savvy software engineers to produce a fully-integrated driver.

As discussed in the previous chapter, the term device driver in Windows 2000 can describe a block of code miles away from any real hardware. Sooner or later, however, a device driver author must understand hardware and the terms sufficient to drive it. This chapter gives a gentle overview of hardware found on most systems.
