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 sources they had something for the sis 7012, and also find later the drivers for the sensors.
So we'll compiling the latest sources from ALSA, which should work for any other distrib as well... just the kernel sources 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 sources for the kernel used in 8.0:
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
Paolo reports that in order to start up sensord on boot, he put in /etc/sysconfig/sensors:
MODULE_0=i2c-proc
MODULE_1=it87
MODULE_2=i2c-isa
If you are using a 2.4 or later kernel you can use the Audio Codec '97 (AC'97) sound driver, as the integrated sound card is AC'97 complaint.
You may enable your soundcard with a kernel module, as a matter of fact, you should be able to just use the module without even recompiling your kernel, because most GNU/Linux distributions have it already, just type:
modprobe i810_audio
and you should see something like this in your syslog:
Intel 810 + AC97 Audio, version 0.21, 21:31:04 Apr 15 2002
i810: SiS 7012 found at IO 0xd800 and 0xdc00, IRQ 11
i810_audio: Audio Controller supports 2 channels.
ac97_codec: AC97 Audio codec, id: 0x414c:0x4710 (ALC200/200P)
i810_audio: AC'97 codec 0 supports AMAP, total channels = 2
or type
dmesg | less and scroll to see the kernel messages.
If everything went fine, you may add i810_audio to
/etc/modules so it will autoload everytime you boot:
echo "i810_audio" >> /etc/modules
or you like monolitic kernels (no modules), follow the step above to install
the kernel sources
and say Y to Sound card support and Y to Intel ICH (i8xx) audio
support
compile your kernel, install, reboot and now your integrated soundcard is
working.
If you don't know how to compile a kernel, read the Kernel HOWTO, it's easy and you'll get a optimized kernel for you system, also you'll learn a bit about that talk of using the source code (yes you are already taking advantage of it :-)
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 sources 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
When it works, you can write it to a file, that will be loaded automatically on
boot. Under
SuSE the file is:
/etc/init.d/boot.local (used to be /sbin/init.d/)
and you should just add: sensors -s
Under mandrake, the install should have created that file:
/etc/init.d/sensors, which you can edit freely, sensord being just a
daemon to watch over temperature and fan speed, I assume no one
will need something like that for her/his own machine.
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 -(36/10)*@, -@/(36/10)
#(7.67 * @) - 27.36 , (@ + 27.36) / 7.67
compute in6 -(56/10)*@, -@/(56/10)

If your board came with the optional on-board LAN card, you have a Silicon Integrated Systems [SiS] SiS900 10/100 Fast Ethernet card, this card is supported by Linux kernels 2.4 and later (that I know of, as I only use 2.4 kernels).
To make it work you should type
modprobe sis900
and you should see something like this in your syslog:
sis900.c: v1.08.02 11/30/2001
eth0: SiS 900 PCI Fast Ethernet at 0xd400, IRQ 5, 00:d0:09:ea:7a:98.
or type
dmesg | less and scroll to see the kernel messages.
If everything went fine, you may add sis900.o to /etc/modules
so it will autoload everytime you boot:
echo "sis900" >> /etc/modules
or compile it in your kernel, where you should say Y to SiS 900/7016 PCI
Fast Ethernet Adapter support in your kernel
configuration.
Warning: If your board is working fine, then don't fix it. Anyway here are the cool links:
Using a modified BIOS, I was able to successfully overclock my Athlon 1000Mhz to 1050Mhz flawlessy, but when I messed with hdparm (30Gig Western Digital hard drive) using hdparm -c1 -X66 /dev/hda, I managed to corrupt my filesystem, so beware.
If you are a real tweaker, you might want to change your BIOS Logo and stuff, some people tried that and it worked OK, some others not, so they had to flash their BIOS again (blindly with a bootdisk and a working bios in it) to make the board work again. It is really up to you. Search Google or OC Workbench and you'll be on your way.
Good Luck! :-)
