LAN Controller Registers (B1:D8:F0) (Desktop and Mobile Only)
8 LAN Controller Registers
(B1:D8:F0) (Desktop and
Mobile Only)
Note:
LAN is not supported on ICH7-U Ultra Mobile.
The ICH7 integrated LAN controller appears to reside at PCI Device 8, Function 0 on the
secondary side of the ICH7’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.
