Record Type ID. For all records defined in this document, a value of D0h (OEM) should
be used.
End of List/Version:
Record Length (in bytes)
Record Checksum. Holds the zero checksum of the record (calculated according to the
FRU specification).
Header Checksum. Holds the zero checksum of the header (calculated according to
the FRU specification).
Manufacturer ID. LS byte first. Write as a three byte ID = 000157h.
Record Format Version/Intel Record ID:
MAC Address Definition list. A variable-length list of eight-byte MAC Address
Definitions (see
describes one Ethernet interface for the referenced FRU.

• 7:7 – End of List. Set to one for the last record.
• 6:4 – Reserved, write as 0h
• 3:0 – Record format version (=2h for this definition)
• 7:5 – MAC Addresses Record format version (=0h for this definition)
• 4:0 – Intel Record ID. For the MAC Addresses Record, a value 00h should be used.
• 7:7 - New definition. Set to 1 for a new MAC address definition.
• 6:0 - Interface type. The following values should be used:
0h – external debug interface
3h – PCI GE interface
6h – SPI-3 GE interface
Bh – NPU internal debug interface #1
Ch – NPU internal debug interface #2
Dh – NPU internal GE interface #1
Eh – NPU internal GE interface #2
This bit is set when a new MAC address has been defined and needs to be
burned into flash. This is an optimization that allows faster startup, that is, the
MAC address burning is only done when needed.
