   The main problem I encountered when considering this myself was that while
you could read the EEPROM soft settings and use them, the soft settings may
not actually be the current settings in use. Most of the cards have jumpers
that select specific hard settings or the soft settings and I could not find
any documentation on how to read how the jumpers were set.
