Ethernet Individual Address (Words 00h - 02h)
The Ethernet Individual Address (IA) is a six-byte field that must be unique for each
adapter card or LOM and unique for each copy of the NVM image. The first three bytes
are vendor specific. (For example, these bytes equal 00 AA 00 or 00 A0 C9 for Intel
products.) The last three bytes must be unique for each copy of the NVM. OEM versions
of the product might be required to have non-Intel ID’s in the first three byte positions.
The value from this field is loaded into the Receive Address Register 0 (RAL0/RAH0).
The Intel default is listed in
Ethernet Individual Address (Words 00h - 02h)
The Ethernet IA is byte swapped, as listed in
The IA bytes read from the NVM are used by the ICH9 until an IA Setup command is
issued by software. The IA defined by the IA Setup command overrides the IA read
from the NVM.
