How I can read fru information about cpu and dimm ?

[Andrei Kartashev]

Hello Alexander,

We can't tell you how to work with your hardware without any knowledge
about it's design.

Typically, CPU have no any EEPROM to read information from it. DIMMs
have special I2C channel, called SPD, but generally it is not connected
to BMC. I guess, you need to use some communication with the host to
request this information. But all this is common suggestion, you need
to know your hardware.
