SID — Subsystem Identification
(LAN Controller—B1:D8:F0)
Offset Address: 2Eh
Default Value:
The ICH7’s integrated LAN controller provides support for configurable Subsystem ID
and Subsystem Vendor ID fields. After reset, the LAN controller automatically reads
addresses Ah through Ch, and 23h of the EEPROM. The LAN controller checks bits
15:13 in the EEPROM word Ah, and functions according to
Configuration of Subsystem ID and Subsystem Vendor ID via EEPROM

The Device ID is loaded from Word 23h only if the value of Word 23h is not 0000h or FFFFh
The Revision ID is subject to change according to the silicon stepping.
Subsystem ID (SID) — RO.
Capabilities Pointer (CAP_PTR) — RO. Hardwired to DCh to indicate the offset within
configuration space for the location of the Power Management registers.
Interrupt Line (INT_LN) — R/W. This field identifies the system interrupt line to
which the LAN controller’s PCI interrupt request pin (as defined in the Interrupt Pin
Register) is routed.
