All RFX boards currently shipping are configured for MIMO_B mode, which
requires a Rev 4 or higher USRP (serial number greater than 500).

If you wish to use it with a USRP with a serial number below 500 you
will need to do the following:

    Remove R115 (zero ohms) and place it at R116
    Remove R36 (zero ohms) and place it at R34
    Put the RFX on a USRP (side A) and run the following:

       usrp/host/apps/burn-db-eeprom -f -A -t rfxYYYY_mimo_a

            where YYYY is the board you have (i.e. 400, 900, 1200, 1800,
or 2400).
