8.1.2
Bit
Description
15:0 Vendor ID — RO. This is a 16-bit value assigned to Intel.
DID—Device Identification Register
(LAN Controller—B1:D8:F0)
Offset Address: 02–03h
Default Value: 1065h
Attribute:
Size:
RO
16 bits
Bit
Description
Device ID — RO. This is a 16-bit value assigned to the ICH6 integrated LAN controller.
1. If the EEPROM is not present (or not properly programmed), reads to the Device ID return the
15:0
default value of 1065h.
2. If the EEPROM is present (and properly programmed) and if the value of word 23h is not 0000h
or FFFFh, the Device ID is loaded from the EEPROM, word 23h after the hardware reset. (See
Section 8.1.14 - SID, Subsystem ID of LAN controller for detail)
