Although we had hoped for the upgrade to be only a ROM change, when 
it finally got down to it, we needed to change a number of 
components in both the analog and digital sections of the modem to 
get the performance we want (and know our users demand).  Yes, it 
does include faster parts, but also more precise parts to improve 
signal quality.  The "upgrade" is really a complete replacement for 
the circuit board in the modem (it's better to replace the board 
with a factory-built one than try to manually replace the parts that 
need replacing).
