I got the mainboard for christmas 2001, and after a little while, I understood that the new chipset sis735 was not handled by mandrake 8.0, OSS had drivers for it that worked but I didn't really want to pay for it, so I looked on alsa cvs and found that in their latest source they had something for the sis 7012, and also find later the drivers for the sensors.
So we'll compile the latest sources from alsa, which should work for any other distrib as well... just the kernel source will change because mandrake uses specific patches You may get your kernel sources from your distribution or from http://www.kernel.org Here can be found Mandrake source for the kernel used in 8.0: ftp://ftp.univ-savoie.fr/pub/Linux/Mandrake/8.0/i586/Mandrake/RPMS/kernel-source-2.4.3-20mdk.i586.rpm and grab the tarball from alsa: ftp://ftp.alsa-project.org/pub/driver/alsa-driver-0.9.0beta10.tar.bz2
Install your kernel sources, in my case:
rpm -ivh kernel-source-2.4.3-20mdk.i586.rpm
Then decompress alsa drivers:
bzip2 -d alsa-driver-0.9.0beta10.tar.bz2 && tar -xvf alsa-driver-0.9.0beta10.tar
Make them and install them and create the devices files:
cd alsa-driver-0.9.0beta10 && make install && ./snddevices
Edit /etc/modules.conf to set everything, and add to it the following lines:
alias char-major-116 snd
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-card-intel8x0
Get the lm_sensors 2.6.2 or more recent: http://www.lm-sensors.nu/archive/lm_sensors-2.6.2.tar.gz You'll need kernel source too in order to compile that one
tar -xzvf i2c-2.6.2.tar.gz
cd i2c-2.6.2
make && make install
Then there was a problem when making install for me, so if it doesn't work, just do the following:
cp kernel/i2c-core.o /lib/modules/`uname -r`/misc/i2c-core.o
cp kernel/i2c-proc.o /lib/modules/`uname -r`/misc/i2c-proc.o
Now let's copy the specific driver:
cp kernel/chips/it87.o /lib/modules/`uname -r`/misc/it87.o
ok now
cp prog/sensors/sensors /usr/bin/sensors
--------------------------------------------------------------------
Edit /etc/modules.conf and add to it the following lines:
alias char-major-89 i2c-dev
options it87 temp_type=0x31
now:
modprobe i2c-proc
modprobe it87
modprobe i2c-isa
sensors
should output you some data
now as root you should edit your /etc/sensors.conf search for that line: chip "it87-*" and below you should be able to modify everything to get the right data, here is a copy of what i have in there: (please note that temp1 is trash and only temp2 and temp3 should be kept)

# For this family of chips the negative voltage equation is different from
# the lm78. The chip uses two external resistor for scaling but one is
# tied to a positive reference voltage. See ITE8705/12 datasheet (SIS950
# data sheet is wrong)
# Vs = (1 + Rin/Rf) * Vin - (Rin/Rf) * Vref.
# Vref = 4.096 volts, Vin is voltage measured, Vs is actual voltage.
compute in2 (1 + 1)*@ , @/(1 + 1)
compute in3 ((6.8/10)+1)*@ , @/((6.8/10)+1)
compute in4 ((30/10) +1)*@ , @/((30/10) +1)
# The next two are negative voltages (-12 and -5).
# The following formulas must be used. Unfortunately the datasheet
# does not give recommendations for Rin, Rf, but we can back into
# them based on a nominal +2V input to the chip, together with a 4.096V Vref.
# Formula:
# actual V = (Vmeasured * (1 + Rin/Rf)) - (Vref * (Rin/Rf))
# For -12V input use Rin/Rf = 6.68
# For -5V input use Rin/Rf = 3.33
# Then you can convert the forumula to a standard form like:
compute in5 (7.67 * @) - 27.36 , (@ + 27.36) / 7.67
compute in6 (4.33 * @) - 13.64 , (@ + 13.64) / 4.33
