 Mango has a block of MAC addresses assigned by the IEEE: {{{40-D8-55-04-20-00}}} to {{{40-D8-55-04-2F-FF}}}. We allocate two addresses from this range for each WARP v3 board. You can find your node's reserved addresses on a label on the back of the board. These addresses are also recorded in the board's EEPROM during manufacturing (see the [wiki:../EEPROM EEPROM page] for details).
 
-'''Note''': early WARP v3 kits did not include this label, nor do early kits have MAC addresses in the EEPROM. '''For boards with serial numbers lower than W3-a-00110''', you can calculate your board's addresses with:

 For example, for serial number W3-a-00050 the allocated addresses are {{{40-D8-55-04-20-64}}} and {{{40-D8-55-04-20-65}}}.
 
-For boards with serial numbers higher than W3-a-00110 this mapping does not apply. The assigned addresses will have no relation to the board serial number.
+We have prepared an FPGA design which will calculate these MAC addresses and store them in the EEPROM. To use it:
+ 1. Download [attachment:WARPv3_MAC-Addr-EEPROM_Init.zip WARPv3_MAC-Addr-EEPROM_Init.zip].
+ 1. Connect your WARP v3 kit to power, JTAG and USB-UART, configured for 57600bps.
+ 1. Configure the FPGA with the download.bit file in .zip archive.
+ 1. Watch the UART output for status messages.

+'''For boards with serial numbers higher than W3-a-00110''': these boards include the MAC address label and  their EEPROMs are pre-programmed with the MAC addresses. For these newer kits there is no relation between serial number and MAC address.
