    No, the motherboard thought that my 24C16 was a set of 3 DIMMs
    (answering at 0x50 - 0x57, and DIMMs seem to be at 0x50, 0x51 and 0x52).
    Of course the data read back was some product of both DIMM EEPROM and
    my 24C16 but the machine didn't pass POST.

    I think anyone trying to connect an EEPROM to SMBus has to make sure
    there is nothing there, and nothing is expected by things like BIOS.
    Not a very plug and play.

    Sure, that's one of the options.
