AP-409 - I/O Control Hub 2, 3, 4 EEPROM Map: Application Note

Introduction and Scope

The scope of this application note describes the EEPROM and its contents for products based upon the Intel® I/O Control Hub 2 (ICH2), I/O Control Hub 3 (ICH3), and I/O Control Hub 4 (ICH4) devices. These components include an integrated 10/100 Mbps LAN controller.

The EEPROM is used for hardwa...re and software configuration. It is read by software to determine and configure specific design features. For compatibility, Intel does not create separate drivers for the integrated ICH2, ICH3, and ICH4 controllers.

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).
