PBA Number (Word 0x08 and 0x09)
The nine-digit Printed Board Assembly (PBA) number used for Intel manufactured
Network Interface Cards (NICs) is stored in the EEPROM.
Note that through the course of hardware ECOs, the suffix field is incremented. The
purpose of this information is to enable customer support (or any user) to identify the
revision level of a product.
Network driver software should not rely on this field to identify the product or its
capabilities.
Current PBA numbers have exceeded the length that can be stored as hex values in
these two words. For these PBA numbers the high word is a flag (0xFAFA) indicating
that the PBA is stored in a separate PBA block. The low word is a pointer to a PBA block.

The PBA block contains the complete PBA number including the dash and the first digit
of the 3-digit suffix. For example:

Older PBA numbers starting with (A,B,C,D,E) are stored directly in words 0x08 and
0x09. The dash itself is not stored nor is the first digit of the 3-digit suffix, as it is
always 0b for relevant products.
