ICH8—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
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 sp ec ified, all numbers in this document use the f ollowing 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).
®
I/O Control Hub 8 (ICH8) device.
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. This combi ned image is show n 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
and Advanced Fan Speed Control. The system BIOS is contained in the BIOS Region.
The ME Region and BIOS Region are beyond t he scope of this document and a more
detailed explanation of these areas can be found in the Intel
(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.

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 EDS. The
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 A c tive Client Manager kit on ARMS
(https://platformsw.intel.com/) or by contacting your local Intel representative.
2. The GbE region must be part of th e 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 reg ister of the GbE LAN Memory Mapped Con fi guration 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). F or the
82562V, this bit can be set to 0b, since it does not us e the GLCI bus.

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 25 6-byte sect or 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 C he c ksum. This file can be created in a simple
text editor and follows the format shown in Appendix A, whic h provides examples of
GbE Region NVM maps for ICH8-based designs. Fast Ethernet (82562V) images are
also provided.
1.3 EEUPDATE Utility
Intel has created an EEUPD ATE utility that can be us ed to up date the GbE region
images during in -circu it pro gr amming. T he too l uses t wo b asic d ata fil es outli ned i n the
following sect io n ( sta tic data file and IA addres s 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 repres entative.
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 Et hernet Individual Address.
Parameter_2 = filename
In Example 1, Pa rameter_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 ad dress, a log file c alled eelog .dat is updat ed with that addre ss. This update d

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 A 0 C9 for Intel
products.) The last three bytes must be unique for each copy of the NVM. OEM versions
of the product m ight be requ ired t o ha ve non- Inte l ID’ s in th e fi rst thr ee by te po sitio ns.
The value from this field is loaded into the Receive Address Register 0 (RAL0/RAH0).
The Intel default is listed in Table 2.

Note: The Ethernet IA is byte swapped, as listed in Table 2.
The IA bytes read from the NVM are used by the ICH8 until an IA Setup comm a nd is
issued by software. The IA defined by the IA Setup command overrides the IA read
from the NVM.
