Forgive me as I haven't tried every iobase. I figured, since my bios is
defaulting to 0x3f8, then auto.c should be fine with 0x3f8.
I did notice a lot of 0x7f8 specified in the SuperIO files. It seems as
if the 0x7f8 is being used with PNP? Well, I even went as far as
replacing all those with original sensible value as were listed in
LinuxBiosv1 W83977EF code.

Looking at the data sheets...
- The TF suppports 13 IRQs, the EF only 12.
- The TF has
"23 programmable general purpose I/O ports; 3 dedicate, 20 optional",
the EF has only
"14 programmable general purpose I/O ports; 6 dedicate, 8 optional".
Oh, and the TF is compliant wih the Microsoft PC97 Hardware Design
the EF with the PC98 version of same. Big Deal.
Other than that, they look identical.

As i said in my previous email, I'm going to work on my Tyan S1832DL
(same SuperIO as the S1846). Maybe I'm doing something wrong still too
or the bug will present itself.
