xx xx xx???
uuid.bios = ???xx xx xx xxxx xx xx xx-xx xx xx xx xx xx xx

*Note: The new MAC address (XX:XX:XX:AA:BB:CC) has some limitations:
The AA must be a valid hexadecimal number between 00h and 3Fh.
The BB and CC must be a valid hexadecimal number between 00h and FFh.
Assign a new MAC address based on the parameters stated above. In this
case, the new MAC address is 00:50:56:3F:FF:FF.
Spoofing 297
By returning to the virtual computer and running the ipconfig /all command

machine will have the new MAC address.
