The integrated GbE controller requires a single, external, EEPROM device to configure 

parameters for all LAN Ports and PCI Functions including MAC Addresses, LED 

behaviors, receive packet filters for manageability, wakeup capability. EEPROM-less 

operation is not supported.

Contents of the EEPROM are always addressed as 16-bit words. When an offset value is 

shown, it is always in terms of 16-bit words.

Some of the EEPROM 16-bit words are used to specify hardware parameters that affect 

all four GbE interfaces such as those affecting circuit behavior. Other EEPROM words 

are associated with a specific GbE interface. All GbE interfaces access the EEPROM to 

obtain their respective configuration settings.

Customers are advised to contact Intel concerning their GbE EEPROM needs. Intel 

provides a number of EEPROM image files for SoC customers to use in their designs. 

These files are considered “starter images” and to some extent can be altered for a 

customer’s particular usage. Intel provides tools for customers to program images to 

the system for various Operating Systems. Contact the Intel sales representative for 

details. If Intel needs to provide EEPROM updates to customers, Intel provides the 

necessary software tools to do this.

The nine EEPROM starter images currently offered (list is subject to change) are shown 

in 

. Each image is padded with bits to provide an image of 8K 16-bit words 

(16K bytes).
