1.4.11 Device ID (Word 0Dh)
If the Load Vendor/Device IDs bit in word 0Ah is set to 1b, this word is read to initialize
the Device ID of the LAN function.
1.4.12 Vendor ID (Word 0Eh)
If the Load Vendor/Device IDs bit in word 0Ah is set to 1b, this word is read to initialize
the Vendor ID. The default Vendor ID value is 8086h.
1.4.13 Device Rev ID (word 0Fh)
1.4.14 LAN Power Consumption (Word 10h)
This word is only relevant when power management is enabled.

LAN D0
Power
0Dh for 82566
04h for 82562V
The value in this field is reflected in the PCI Power Management
Data Register of the LAN function for D0 power consumption and
dissipation (Data_Select = 0 or 4). Power is defined in 100 mW
units and includes the external logic required for the LAN function.
7:5 Reserved 000b These bits are reserved and should be set to 000b.
4:0
LAN D3
Power
00001b for 82566
00010b for 82562V
The value in this field is reflected in the PCI Power Management
Data Register of the LAN function for D3 power consumption and
dissipation (Data_Select = 3 or 7). Power is defined in 100 mW
units and includes the external logic required for the LAN function.
The most significant bits in the Data Register that reflects the
power values are padded with zeros.
