Hi all,
This is my first email to this mailing
list. I've joined because I've a little question related to the
BIOS superio initialization process
and I would like to ask to the masters.
I'm developing a little hardware module
with a w83627hf superio module. My testing platform
is using the linux kernel is 2.6.26,
and the kernel driver I'm trying to use is driver/hwmon/w83627hf.c.
This hardware is attached to a com express
module. I've found that my hardware is not always initialized
by the com express BIOS, it depends
on the manufacter.
The com express from Congatec (conga-BA945)
do it ok. The BIOS sets the hardware monitor device
address correctly and I can load the
kernel driver and read the voltages and temps.
But another one from MSC (MSC CXB-CD945)
it doesn't, then the linux kernel driver refuses to load
because the hardware monitor address
is not set. I can force this addres (the same that I get from the
congatec module) to force the kernel
driver loading but the voltages and temps are not read.
Then, I think that the hardware is working
but I need some initialization in the southbridge or something
else that the first BIOS is doing. Where
can I looking for this info? Both com express modules has the
intel ICH7-M southbridge.
Any help is welcome!
Regards,
Jorge
