+Older RFX boards require modifications to use the motherboard oscillator.
+If this is the case, UHD will print a warning about the modification.
+Please follow the modification procedures below:
+
+**Step 1: Disable the daughterboard clocks**
+
+Move R64 to R84, Move R142 to R153
+
+**Step 2: Connect the motherboard blocks**
+
+Move R35 to R36, Move R117 to R115
+These are all 0-ohm, so if you lose one, just short across the appropriate pads
+
+**Step 3: Burn the appropriate daughterboard id into the EEPROM**
+
+With the daughterboard plugged-in, run the following commands:
+::
+
+    cd <prefix>/share/uhd/utils
+    ./usrp_burn_db_eeprom --id=<rx_id> --unit=RX --args=<args> --slot=<slot>
+    ./usrp_burn_db_eeprom --id=<tx_id> --unit=TX --args=<args> --slot=<slot>
