    I am facing problem in writing EEPROM of RTL8100 card. I want to change
    MAC address of this card Permanently. I have gone throurh data sheet of
    RTL8100. I found way to change MAC address which is like this, change
    the operating mode of network card to CONFIG REGISTER WRITE ENABLE
    mode. Using this procedure, I can change MAC address but this is
    temporary. When I restart my board then original MAC address appears.

    Please tell me some way to burn new MAC address permanently in EEPROM.
    Please reply me on
