Chapter 9: PCI

This chapter presents the PC 98 requirements and recommendations for Peripheral Component Interconnect (PCI) host controllers and peripherals.

The PCI architecture has become the most common method used to extend PCs for add-on adapters. Windows and Windows NT use the basic PCI infrastructure to gain information about devices attached to the PCI bus. The ability of PCI to supply such information makes it an integral part of the Plug and Play architecture in Windows.

Specific requirements related to PCI are defined in the following chapters:

• Requirements for dual IDE adapters that use PCI are defined in the “IDE and ATAPI” chapter in Part 3 of this guide.
  
  
• Requirements for PCI-to-PC Card bridges are defined in the “PC Card” chapter in Part 3 of this guide.
  
  
• Requirements for graphics devices that use PCI are defined in the “Graphics Adapters” chapter in Part 4 of this guide.
  
  
• Requirements for audio implementations that use PCI are defined in the “Audio Components” chapter in Part 4 of this guide.
