The NVM image contains both static and dynamic data. The static data is the basic
platform configuration, and includes OEM specific configuration bits as well as the
unique Printed Circuit Board Assembly (PBA). The dynamic data holds the product’s
Ethernet Individual Address (IA) and Checksum. This file can be created using a text
editor.

4. The GbE region of the NVM must be accessible. To keep this region accessible, the
5. The sector size of the NVM must equal 256 bytes, 4 KB, or 64 KB. When a Flash
Protected Range register of the GbE LAN Memory Mapped Configuration registers
must be set to their default value of 0x0000 0000. (The GbE Protected Range
registers are described in the Intel
device that uses a 64 KB sector erase is used, the GbE region size must equal
128 KB. If the Flash part uses a 4 KB or 256-byte sector erase, then the GbE region
size must be set to 8 KB.
