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
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
4. The GbE region of the NVM must be accessible. To keep this region accessible, the

registers correctly.
There are two sets of VSCC registers, the upper (UVSCC) and lower (LVSCC). Note
that the LVSCC register is only used if the NVM attributes change. For example, the
use of a second flash component, a change in erase size between segments, etc.
Due to the architecture of the ICH9, if these registers are not set correctly, the LAN
tools might not report an error message even though the NVM contents remain
unchanged. Refer to the ICH9 EDS for more information.
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 ICH9 EDS).
must be set correctly. Bit 19 of STRP0 must be set to 1b (as described in the ICH9
EDS). For the 82562V, this bit can be set to 0b, since it does not use the GLCI bus.
