[Tpctl-users] superio: Super I/O chip not found. :-(

[Martin K. <mar...@ze...>]

Hi,

I am new on this list. Sorry, if I am asking a faq. I have checked the
archive, the web and groups.google but couldn't find a soulution for my
problem.

I'm running debian woody on a ThinkPad 760ED. The kernel ist 2.4.27.
The problem is that I can't use the serial and parallel port, because
superio fails to find the Super I/O chip.

What I've done:

First tried to use the debian-Packages (thinkpad-base, thinkpad-source,
tpctl). Compiled thinkpad_modules as described. tpctl worked fine
beside the problem with superio.

Then I deinstalled all the debian stuff and got me the latest sources
from sourceforge (thinkpad_5.8.tar.gz and tpctl_4.15.tar.gz). The
compilation and installation finished without problems. tpctl also
works fine, but I still have the same problems with superio:

  # tpctl --rx
  resource state:                        ioaddr irq#   able? mode/power
  superio: Super I/O chip not found. :-(
  tpctl: module required for request is not loaded.

  # modprobe superio
  thinkpad: I have registered to handle major: 10 minor: 170.
  superio: Super I/O chip not found. :-(

  # insmod superio
  Using /lib/modules/2.4.27/thinkpad/superio.o

Is thinkpad_ppde not just needed for 2.6.x? Could this be the problem?
In the thinkpad-source the 2.4-tree is selected:

  information about bios and system:
     system ID:                           24
     country code:                        1

     slave controller revision:           1.8

Could the BIOS be the problem? It seems to be quite old.

When I bought the ThinkPad (secondhand) a few weeks ago, I tested the
parallel port with the installed Win95, because I have a win-only
printer here, which I wanted to test before I sell it. The printer
worked, so I assume there is nothing wrong with the superio-chip. I
don't have any Windows here anymore, but if it is necessary to test
the ports again, I will try to get one. The floppy is working, only
the serial and parallel ports don't work. I didn't test IrDA though.

Thanks for your help,
Martin
