LAN Controller Registers (B1:D8:F0)
LAN Controller Registers (B1:D8:F0) 7
The ICH3 integrated LAN Controller appears to reside at PCI Device 8, Function 0 on the
secondary side of the ICH3’s virtual PCI-to-PCI Bridge (See Section 5.1.2). 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.
