I've seen some responses, but can someone give me an explanation for the 
2096128 value from the byte level up (I think we can agree on 8 bits per byte 
for now...)? Because no matter how I count 2096128 doesn't make sense as a 2GB 
31 bit addressing maximum value if you get my drift.

Regards,

Erik.
