Compatibility Fields (Words 0x03 - 0x07)
Five words in the NVM image are reserved for compatibility information. New bits
within these fields can be defined as the need arises for determining software
compatibility between various hardware revisions.
PBA Number (Word 0x08 and 0x09)
The nine-digit Printed Board Assembly (PBA) number used for Intel manufactured
Network Interface Cards (NICs) are stored in a 4-byte field. The dash itself is not
stored, neither is the first digit of the 3-digit suffix, as it is always zero for the affected
products. Note that through the course of hardware ECOs, the suffix field (byte 4) is
incremented. The purpose of this information is to enable customer support (or any
user) to identify the exact revision level of a product. Network driver software should
not rely on this field to identify the product or its capabilities.
PXE Words (Words 0x30h:0x3E)
Words 0x30 through 0x3E are reserved for software and are used by IBA/PXE software.
