Table 135. Configuration of Subsystem ID and Subsystem Vendor ID via EEPROM
Note: The ICH5’s integrated LAN controller provides support for configurable Subsystem ID and
SID — Subsystem Identification Register
(LAN Controller—B1:D8:F0)
Offset Address:
Default Value:
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

Default Value:
INT_LN — Interrupt Line Register
(LAN Controller—B1:D8:F0)
Offset Address:
Default Value:
1. The Revision ID is subject to change according to the silicon stepping.
2. The Device ID is loaded from Word 23h only if the value of Word 23h is not 0000h or FFFFh

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.
