To access the NVM, it is essential to correctly setup the following:

1.A valid Flash Descriptor Region must be present. Details for the Flash Descriptor Region are contained in the ICH8 EDS. The FTOOL.exe utility provides the easiest method of configuring this descriptor region. This process is described in detail in the Intel® Active Management Technology OEM Bring-Up Guide.

FTOOL.exe and the Intel® Active Management Technology OEM Bring-Up Guide can be obtained as part of the Intel Active Client Manager kit on ARMS (https://platformsw.intel.com/) or by contacting your local Intel representative.

2.The GbE region must be part of the original image flashed onto the part.

3.For Intel LAN tools and drivers to work correctly, the BIOS must set the VSCC register(s) correctly. This information is described in ICH8 EDS, section 24.1.

4.The GbE region of the NVM must be accessible. To keep this region accessible, the Protected Range register of the GbE LAN Memory Mapped Configuration registers must be set to their default value of 0000 0000h. (The GbE Protected Range registers are described in the ICH8 EDS).

5.If you are using the 82566, the ICH8 soft strap for the GLCI interface must be set correctly. Bit 19 of STRP0 must be set to 1b (as described in the ICH8 EDS). For the 82562V, this bit can be set to 0b, since it does not use the GLCI bus.
