Table 6-1. PCI Devices and Functions
Note: From a software perspective, the integrated LAN controller resides on the ICH6’s external PCI bus.
PCI Devices and Functions
The ICH6 incorporates a variety of PCI functions as shown in
divided into six logical devices (B0:D30, B0:D31, B0:D29, B0:D28, B0:D27 and B1:D8). D30
contains the DMI interface-to-PCI bridge and the AC ’97 Audio and Modem controller. D31
contains the PCI-to-LPC bridge, IDE controller, SATA controller, and the SMBus controller. D29
contains the four USB UHCI controllers and one USB EHCI controller. D27 contains the Intel
High Definition Audio controller. B1:D8 is the integrated LAN controller.
This is typically Bus 1, but may be assigned a different number depending on system configuration.
If for some reason, the particular system platform does not want to support any one of the Device
Functions, with the exception of D30:F0, they can individually be disabled. The integrated LAN
controller will be disabled if no Platform LAN Connect component is detected (See
When a function is disabled, it does not appear at all to the software. A disabled function will not
respond to any register reads or writes, insuring that these devices appear hidden to software.
NOTES:
1. The LPC controller contains registers that control LPC, Power Management, System Management, GPIO,
