Refer to Section 2. for full-pin descriptions and Section 7. for the timing characteristics of those
interfaces.
1.9.3 EEPROM Interface
The 82598EB uses an EEPROM device for storing product configuration information. Several words of
the EEPROM are accessed by the 82598EB after reset in order to provide pre-boot configuration data
that must be available to it before it is accessed by host software. The remainder of stored information
is accessed by various software modules used to report product configuration, serial number, etc.
The 82598EB uses a SPI (4-wire) serial EEPROM device such as a AT25040AN or compatible. Refer to
Section 2. for full-pin descriptions and Section 7. for the timing characteristics of those interfaces.
