3.2.2Serial EEPROM

The 82575 Ethernet Controller Gigabit Ethernet Controller uses an Serial Peripheral Interface (SPI)* EEPROM. Several words of the EEPROM are accessed automatically by the device after reset to provide pre-boot configuration data before it is accessed by host software. The remainder of the EEPROM space is available to software for storing the MAC address, serial numbers, and additional information. This information is available to the 82575 Ethernet Controller also and is part of the pre-boot configuration data.

The 82575 has a thermal sensor that can send alerts. Trip points for the sensor are set in the EEPROM. For information regarding the use of the sensor and the programming its function in the EEPROM, please refer to the EEPROM Programming Information and Map Application Note.

3.2.2.1General Regions

The EEPROM is divided into four regions based on the type of access:

Hardware accessed--this region is accessed by other hardware

Alert (ASF) accessed--this region is accessed by alert routines

PT accessed--this region is accessed by the pass-through routines

Software accessed--this region is accessed by applications

3.2.2.2EEPROM-less Operation

The 82575 can be operated without an EEPROM, however the following conditions apply:

Non-manageability mode only
