After writing down the binary representation of the mac address, read the
binary from left to right instead of right to left. in other words,
something like 04d0 binary 0000 0100 1101 0000 when read from left to right
becomes 02b0. then swap the nibbles so 02b0 becomes 200b.
And yes, I'm still on cloud nine!!!
