System EEPROMs


The BMC has access via I2C buses to the BMC FRU EEPROM device which contains production data (e.g., product name, part number, serial number, etc).

The EEPROM device is programmed during manufacturing to read its content by using Intelligent Platform Management Interface (IPMI) commands directed to the BMC. The ipmitool command fru print displays the contents of FRU EEPROM.

The BMC u-boot console cannot access system EEPROMs.

From a content perspective, the EEPROMs is formatted to follow IPMI FRU format, as documented in the IPMI Platform Management FRU Information Storage Definition, which is downloadable on the internet. The BMC FRU EEPROM utilizes the "multi-record info" area to specify NVIDIA-specific information. In this case it is the MAC address for the BMC Ethernet ports (eth0).
