To be precise, the info actually is read from a register on the chip, not a 
register on the motherboard (the chip is on the motherboard ofcourse).

So there really is no difference here, a register gets read and based on its 
contents it gets determined what inputs are available and what their types are.

As an added bonus, one can also determine the scaling factors and labels for 
the inputs too.
