LAN Controller Registers (B1:D8:F0)
8 LAN Controller Registers
(B1:D8:F0)
The ICH6 integrated LAN controller appears to reside at PCI Device 8, Function 0 on the
secondary side of the ICH6’s virtual PCI-to-PCI bridge. This is typically Bus 1, but may be
assigned a different number depending upon system configuration. The LAN controller acts as
both a master and a slave on the PCI bus. As a master, the LAN controller interacts with the system
main memory to access data for transmission or deposit received data. As a slave, some of the LAN
controller’s control structures are accessed by the host processor to read or write information to the
on-chip registers. The processor also provides the LAN controller with the necessary commands
and pointers that allow it to process receive and transmit data.
