- Module Name: PciLib.h\r
+ Provides services to access PCI Configuration Space.\r
+ \r
+ These functions perform PCI configuration cycles using the default PCI configuration \r
+ access method. This may use I/O ports 0xCF8 and 0xCFC to perform PCI configuration accesses, \r
+ or it may use MMIO registers relative to the PcdPciExpressBaseAddress, or it may use some \r
+ alternate access method. Modules will typically use the PCI Library for its PCI configuration \r
+ accesses. However, if a module requires a mix of PCI access methods, the PCI CF8 Library or \r
+ PCI Express Library may be used in conjunction with the PCI Library. The functionality of \r
+ these three libraries is identical. The PCI CF8 Library and PCI Express Library simply use \r
+ explicit access methods.\r
