Out of curiosity, did a search on google for this superio and noticed a
similar discussion. Some recommendations of also using a Bios Post Card.
If you think it'd be wise, I'll grab one for $30 or so.

w83977ef-ctf.pdf
w83977tf.pdf

Both chips seem similar along with using 0x3f0 and 0x370 twice to put
the chip into extended mode. (I think this is why 0x3f0 is being passed
for?)

Anyways, I've seen no output on serial yet with using the
0x3f0,0x3f0,0x370 values so far.

If these values are what I'm thinking is there a need to use other
values for this function?  (..forgive my C lingo. :-/)
