ICH8/ICH9—NVM Information Guide
1.0 Non-Volatile Memory (NVM)
1.1 Introduction
The document is intended for designs using the 10/100/1000 Mb/s LAN controller that
is integrated into the Intel
®
I/O Control Hub 8 or I/O Control Hub 9 (ICH8/ICH9)
device.
The Non-Volatile Memory (NVM) space is used for hardware and software configuration.
It is read by software to determine and configure specific design features.
Unless otherwise specified, all numbers in this document use the following numbering
convention:
• Numbers that do not have a suffix are decimal (base 10).
• Numbers with a suffix of “h” are hexadecimal (base 16).
• Numbers with a suffix of “b” are binary (base 2).
1.2 NVM Programming Procedure Overview
The LAN NVM shares space on an SPI Flash device (or devices) along with the BIOS,
Manageability Firmware, and a Flash Descriptor Region. It is programmed through the
ICH8/ICH9. This combined image is shown in Figure 1. The Flash Descriptor Region is
used to define vendor specific information and the location, allocated space, and read
and write permissions for each region. The Manageability (ME) Region contains the
code and configuration data for ME functions such as Intel
Technology, ASF, and Advanced Fan Speed Control. The system BIOS is contained in
the BIOS Region. The ME Region and BIOS Region are beyond the scope of this
document and a more detailed explanation of these areas can be found in the Intel
O Controller Hub 8 (ICH8) Family External Design Specification (ICH8 EDS) and the
®
I/O Controller Hub 9 (ICH9) Family External Design Specification (ICH9 EDS).

This document describes the LAN image contained in the Gigabit Ethernet (GbE) region.
Fast Ethernet (82562V) images are also described.

NVM Information Guide—ICH8/ICH9
Figure 1. 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/ICH9 EDS. The
easiest method of configuring this descriptor region. This process is described in
detail in the Intel
FTOOL.exe and the Intel
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.
For the ICH9, 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 ICH8/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 ICH8/ICH9 EDS for more
information
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/ICH9 EDS).
5. If you are using the 82566/82567, the ICH8/ICH9 soft strap for the GLCI
interface must be set correctly. Bit 19 of STRP0 must be set to 1b (as described in
the ICH8/ICH9 EDS). For the 82562V, this bit can be set to 0b, since it does not
use the GLCI bus.

FTOOL.exe utility provides the

ICH8/ICH9—NVM Information Guide
6. The sector size of the NVM must equal 256 bytes, 4 KB, or 64 KB. When a Flash
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.
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 in a simple
text editor and follows the format shown in Appendix A, which provides examples of
GbE Region NVM maps for ICH8/ICH9-based designs. Fast Ethernet (82562V) images
are also provided.
1.3 EEUPDATE Utility
Intel has created an EEUPDATE utility that can be used to update the GbE region
images during in-circuit programming. The tool uses two basic data files outlined in the
following section (static data file and IA address file). The EEUPDATE utility is flexible
and can be used to update the entire GbE region image or only the IA address of the
LAN controller. In addition, it also corrects the GbE component checksum field after the
region is modified (FTOOL does not have this ability). For more information on how to
use EEUPDATE, refer to the
utility.
eeupdate.txt file that is included with the EEUPDATE
To obtain a copy of this program, contact your Intel representative.
1.3.1 Command Line Parameters
The DOS command format is as follows:
EEUPDATE Parameter_1 Parameter_2
where:
Parameter_1 = /D or /A
/D is used to update the entire GbE region image.
/A is used to update just the Ethernet Individual Address.
Parameter_2 = filename
In Example 1, Parameter_2 is
a specific format used to update the complete GbE region. All comments in the
file must be preceded by a semicolon (;).
Example 1. EEUPDATE /D file1.eep
In Example 1, Parameter 2 is
EEUPDATE utility finds the first unused address from this file and uses it to update the
NVM. An address is marked used if it is followed by a date stamp. When the utility uses
a specific address, a log file called eelog.dat is updated with that address. This updated
file should be used as the
Appendix A provides an example of the raw GbE region contents. Fast Ethernet
(82562V) images are also provided.

1.4.1 Ethernet Individual Address (Words 00h - 02h)
The Ethernet Individual Address (IA) is a six-byte field that must be unique for each
adapter card or LOM and unique for each copy of the NVM image. The first three bytes
are vendor specific. (For example, these bytes equal 00 AA 00 or 00 A0 C9 for Intel
products.) The last three bytes must be unique for each copy of the NVM. OEM versions
of the product might be required to have non-Intel ID’s in the first three byte positions.
The value from this field is loaded into the Receive Address Register 0 (RAL0/RAH0).
The Intel default is listed in Tab l e 2.

Note: The Ethernet IA is byte swapped, as listed in Tab l e 2 .
The IA bytes read from the NVM are used by the ICH8/ICH9 until an IA Setup
command is issued by software. The IA defined by the IA Setup command overrides the
IA read from the NVM.
