The K26 SOM EEPROM is pre-programmed during manufacturing and provides device configuration, identification, and manufacturing data. The EEPROM content is protected as a read-only interface and organized per the IPMI specification. See the information on EEPROM data mapping in the IPMI Platform Management FRU Information Storage Definition v1.0, Revision 1.3, March 24, 2015.
The K26 SOM EEPROM includes the IPMI records defined in the following table. The addresses are expressed in EEPROM physical address offsets.
