Non-Volatile Memory (NVM) Map
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 areas are as follows:
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 82574L NVM images, contact your Intel representative.
