The nine digit printed board assembly (PBA) number used for Intel manufactured adapter cards are stored in a four-byte field. The dash and the first digit of the three- digit suffix are not stored.

1.4.7.1PBA Example

If the PBA Number is “123456-003”

then word 08h = 1234h and word 09h = 5603h.

Through the course of hardware changes, 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. The software device driver should not rely on this field to identify the product or its capabilities.
