d008 == 1101000000001000
100b == 0001000000001011
It's been a long, long time since I touched/looked at this code (or the
docs!), so don't ask me why this is like it is, but, there you have
it...
I do remember that getting MAC addresses into the EEPROM wasn't much
fun because of the shifting required to get the bits into the right
places.
hope this helps,
