2-2Service Guide2.2 Intel PIIX4
PIIX4 is a multi-function PCI device that integrates many system-level functions.
PCI to ISA/EIO Bridge
PIIX4 is compatible with the PCI Rev 2.1 specification, as well as the IEEE 996 specification for the
ISA (AT) bus. On PCI, PIIX4 operates as a master for various internal modules, such as the USB
controller, DMA controller, IDE bus master controller, distributed DMA masters, and on behalf of
ISA masters. PIIX4 operates as a slave for its internal registers or for cycles...
