Table 7.
PBA Low, PBA High (Words 08h and 09h)
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.
PBA 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.
PCI Initialization Control (Word 0Ah)
This word contains initialization values that:

Auxiliary Power Indication
If set and if PM Ena is set, D3cold wake-up is advertised in the PMC
register of the PCI function.
0b = No AUX power.
1b = AUX power.
Power Management Enable (PME-WoL)
Enables asserting PME in the PCI function at any power state. This bit
affects the advertised PME_Support indication in the PMC register of the
PCI function.
0b = Disable.
1b = Enable.
This bit is reserved and should be set to 0000b.
Load Subsystem IDs from NVM
When set to 1b, indicates that the device is to load its PCI Subsystem ID
and Subsystem Vendor ID from the NVM (words 0Bh and 0Ch).
0b = Do not load.
1b = Load.
Load Vendor/Device IDs from NVM
When set to 0b, the ICH9 loads its PCI Vendor and Device IDs built into
the MAC.
When set to 1b, the ICH9 loads its PCI Vendor ID from NVM word 0Eh
and the Device ID from NVM word 0Dh.
0b = Do not load.
1b = Load.
