Subsystem ID (Word 0x0B)
If the load subsystem IDs in word 0x0A is set, this word is loaded to initialize the
subsystem ID. The default value is 0x0.
Subsystem Vendor ID (Word 0x0C)
If the load subsystem IDs in word 0x0A is set, this word is loaded to initialize the
subsystem vendor ID. The default value is 0x8086.
Device ID (Word 0x0D)
If the load vendor/device IDs in word 0x0A is set, this word is loaded to initialize the
device ID of the function. The default value is 0x10D3 for the 82574.

Default
Initial value of the Assert PME On APM Wakeup bit in the Wake Up
Control register (WUC.APMPME).
Manageability Operation Mode
Using this field selects one of the manageability operation modes.
00b = Manageability disable (clock gated).
01b = NC-SI.
10b = Advanced pass through.
11b = Reserved.
0b = EEPROM.
1b = Flash.
NVM size [bytes]
Equals 128 * 2 ** NVSIZE. (When NVM=Flash the NVSIZE should be
>= 9 ‡. Therefore, the minimal supported Flash size is 64 KB).
Note: A value of 1111b is reserved.
Following are all possible NVSIZE values and their corresponding NVM
sizes (in both bytes and bits):
0000b = 128 B / 1 Kb
0001b = 256 B / 2 Kb
0010b = 0.5 KB / 4 Kb
0011b = 1 KB / 8 Kb
0100b = 2 KB / 16 Kb
0101b = 4 KB / 32 Kb
0110b = 8 KB / 64 Kb
0111b = 16 KB / 128 Kb
1000b = 32 KB / 256 Kb
1001b = 64 KB / 0.5 Mb
1010b = 128 KB / 1 Mb
1011b = 265 KB / 2 Mb
1100b = 0.5 MB / 4 Mb
1101b = 1 MB / 8 Mb
1110b = 2 MB / 16 Mb
