Image Version Information (Word 0x05)
This is a reserved word and cannot be changed.
Care should be taken to use the correct GbE NVM firmware revision for the stepping
combination of the Intel
lists the NVM revision that is optimized for use with the silicon stepping combination.
Using a newer revision NVM with an older silicon stepping or older revision NVM with a
newer silicon stepping could cause system instability and unpredictable behavior.
PBA Low and PBA High (Words 0x08 and 0x09)
The nine-digit Printed Board Assembly (PBA) number used for Intel manufactured
Network Interface Cards (NICs) and Lan on Motherboard (LOMs) are stored in a four-
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
allow 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.
Example: PBA number = 123456-003 to Word 0x08 = 0x1234; Word 0x09 = 0x5603.
