PCI Init Control Word (Word 0x0A)
This word contains initialization values that:
Subsystem ID (Word 0x0B)
If the Load Subsystem ID in word 0x0A is set, this word is read in to initialize the
Subsystem ID. Default value is 0x0000.
Subsystem Vendor ID (Word 0x0C)
If the Load Subsystem ID in word 0x0A is set, this word is read in to initialize the
Subsystem Vendor ID. Default value is 0x8086.
Device ID (Word 0x0D)
If the Load Device ID in word 0x0A is set, this word is read in to initialize the Device ID
of the 82577 PHY. Default value is 0x10EA.
Reserved Words 0x0E and 0x0F

If set and if PM Ena is set, D3cold wake-up is advertised in the Intel
5 Series Express Chipset of the PCI function.
0b = No AUX power.
1b = AUX power.
Power Management Enable (PME-WoL)

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).
Load Device ID from NVM
When set to 1b, indicates that the device is to load its PCI Device ID
from the NVM (word 0Dh).
