Table 1-2. PCI Devices and Functions
Overview
The ICH4 provides extensive I/O support. Functions and capabilities include:
The ICH4 incorporates a variety of PCI functions that are divided into three logical devices
(29, 30, and 31) on PCI Bus 0 and one device on Bus 1. Device 30 is the Hub Interface-To-PCI
bridge. Device 31 contains all the other PCI functions, except the USB controllers and the LAN
controller, as shown in
