The most undiscovered configurations seem to be such ones about antenna
inputs and their switching. Again according to Hartmut, and he did not
know exactly what is going on here, some for us and him at this point
unknown checksums are used to derive even that information :(

For what I can see, and I might be of course still wrong, we can also
not determine plain digital tuner types, digital demodulator types of
any kind and the type of possibly present second and third tuners, but
at least their addresses, regularly shared by multiple chips, become
often visible. (some OEMs have only 0xff still for all that)

forgot, and not any LNB supplies behind some i2c bridges, shared or not
on whatever.

The use of Hauppauge eeproms I consider advisory at best. Yes, they have reasonably good fields to identify tuners, IR but a number of recent silicon additions (last 3 years) to the product line is not fully implemented in the eeproms. Some of the important feature decisions is done purely in software based on sub id for example.

In general I agree with Hermann's comments, that is, where possible making maximum use of the eeprom.
