My understanding is that bitwise endianness is only critical in serial
transfer systems, where the bits could be read out in ascending or
descending order. In parallel transfers, D7 should always carry the MSB
and D0 the LSB, by convention. This is always true for ATA hard drives.
Now we wait for Nasta to say why it isn't so ;)
