ICH7 Family Datasheet
CSR_MEM_BASE — CSR Memory-Mapped Base
Address Register (LAN Controller—B1:D8:F0)
Offset Address: 10h
Default Value:
The ICH7’s integrated LAN controller requires one BAR for memory mapping. Software
determines which BAR (memory or I/O) is used to access the LAN controller’s CSR
registers.
CSR_IO_BASE — CSR I/O-Mapped Base Address Register
(LAN Controller—B1:D8:F0)
Offset Address: 14h
Default Value:
The ICH7’s integrated LAN controller requires one BAR for memory mapping. Software
determines which BAR (memory or I/O) is used to access the LAN controller’s CSR
registers.

Base Address (MEM_ADDR) — R/W. This field contains the upper 20 bits of the base
address provides 4 KB of memory-Mapped space for the LAN controller’s Control/Status
registers.
Reserved
Prefetchable (MEM_PF) — RO. Hardwired to 0 to indicate that this is not a pre-fetchable
memory-Mapped address range.
Type (MEM_TYPE) — RO. Hardwired to 00b to indicate the memory-Mapped address
range may be located anywhere in 32-bit address space.
Memory-Space Indicator (MEM_SPACE) — RO. Hardwired to 0 to indicate that this base
address maps to memory space.
Reserved
Base Address (IO_ADDR)— R/W. This field provides 64 bytes of I/O-Mapped address
space for the LAN controller’s Control/Status registers.
Reserved
I/O Space Indicator (IO_SPACE) — RO. Hardwired to 1 to indicate that this base
address maps to
I/O space.
Subsystem Vendor ID (SVID) — RO. See
