Note:
IICH PCI Devices
Logically, the IICH appears as multiple PCI devices within a single physical component
also residing on PCI bus #0. One of the IICH devices is a PCI-to-PCI bridge. Logically,
the primary side of the bridge resides on PCI #0 while the secondary is a standard PCI
expansion bus.
The internal devices in the IMCH and IICH (except host switch devices) logically
constitute as PCI Bus #0 to configuration software (see Figure 13-1).
