Mh, i just tried it and doesn't work for me :-(. Probably i am to tired and
did a stupid mistake. But well i still can't load the it87 module. But my
tree has the changes in superio.c. Hints are welcome :-). Probably im am
missing a kernel driver or so?
Ward i have also the problem that i don't see any classic PCI cards on my
machine (with linuxbios, works with stock bios), can you confirm this? I see
all the nvidia stuff and the video card though.
I have written a small c program which reads out the values of the ec
controller. It works for me under stock bios but gives "ff" on all reads
under linuxbios :-(. Ward it would be nice if you could try it on your
machine... and yes i was a little bit off with my statement can be take right
of the datasheet. The program needs to be run as root or gives an access
error.
Attached is also the output of the program on my machine under i386 and amd64.
Keep in mind that some of the registers are fan and temperature input so they
differ.
Concerning the question of Uwe, yes if you like i can maintain it on the wiki
but i need an account?
Good night
ST
