LAN NVM Regions

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.
