Non-Volatile Memory (NVM) Map
Note:

Table 24.
The NVM contains two regions located at fixed addresses and various regions located at
programmable addresses throughout the physical NVM space.
The NVM base area resides at word addresses 0x00-0x3F. All defined fields are fixed,
while reserved words might be used by some programmable areas. The base area is
present in the NVM in all system configurations.
The programmable area is as follows:
Additional configuration for the PHY is located in the extended configuration area. The
extended configuration pointer indicates the location of the extended configuration
area. A value of 0x0000 means that the extended configuration area is disabled. This
should be the case for the 82583V.
The NVM image must fit the specific NVM part being used. Special attention should be
paid to NVM words and fields that vary, like the examples of NVMTYPE or NVSIZE. For
the latest 82583V NVM images, contact your Intel representative.
