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 (ICH8) device.
The NVM space is used for hardware and software configuration. It is also 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
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 Active Management 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 I/O Controller Hub 8
(ICH8) Family External Design Specification (ICH8 EDS). This document describes the
LAN image contained in the Gigabit Ethernet (GbE) region. Fast Ethernet (82562V)
images are also described.

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.exeutility 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.exeand the Intel Active Management Technology OEM Bring-Up Guide
can be obtained as part of the Intel Active Client Manager kit on ARMS
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.
6
ICH8—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
GbE Region NVM maps for ICH8-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 eeupdate.txtfile that is included with the EEUPDATE
utility.
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 file1.eep, which contains the complete NVM image in
a specific format used to update the complete GbE region. All comments in the .eep
file must be preceded by a semicolon (;).
Example 1. EEUPDATE /D file1.eep
In Example 1, Parameter 2 is file2.dat, which contains a list of IA addresses. The
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 .datfile for the next update.
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).

If the PBA Number is “123456-003”
then word 08h = 1234h and word 09h = 5603h.
Through the course of hardware changes, the suffix field (byte 4) is incremented. The
purpose of this information is to enable customer support (or any user) to identify the

be used by an OEM to control the operation of the agent in a LOM environment,

The Checksum word (NVM bytes 7Eh and 7Fh) is used to ensure that the base NVM
image is valid. Its value should be calculated by adding all words (00h through 3Fh)/
bytes (00h-7Eh), including the Checksum word itself. The sum, including the
Checksum, should equal BABAh. The initial value before the values are added together
should be 0000h, and the carry bit should be ignored after each addition. If the OEM
does not desire to calculate the checksum, LAD programming tools and drivers will
detect if the checksum is incorrect and fix it in the image.
Note:
The default image always has a checksum value of 0. The default image always has a
checksum value of 0b. The LAD programming tools (EEUPDATE or LANCONF) update
the checksum when the image is programmed.
