How to use Elite's K7s5a mainboard under GNU/Linux.
1. Introduction
1.1. History
I got the mainboard for Christmas 2001, and after a little while, I
understood that the new chipset sis735 was not handled by Mandrake
<http://www.mandrake.com> 8.0, OSS <http://www.opensound.com> 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 a bit later I found the drivers for
the sensors.
It has now been 3 years I started this howto and I am always glad to
get comments, advices from everywhere in the world :]

2. The integrated sound board
2.1. ALSA versus the AC'97 Driver
I have used both solutions successfully. However I noticed while
working on a speech synthesis system (I was involved in a small
accessibility project), that the kernel driver does not seem to be
able to re-sample, whereas Alsa does it perfectly.
2.2. Alsa
2.2.1. Getting the ALSA drivers
So we will be compiling the latest sources from ALSA, which should
work for all other distributions as well... only 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 <http://www.kernel.org/pub/linux/kernel/>
Here can be found Mandrake sources 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 <ftp://ftp.univ-
savoie.fr/pub/Linux/Mandrake/8.0/i586/Mandrake/RPMS/kernel-
source-2.4.3-20mdk.i586.rpm>
(link seems to be broken, I wish I had made a copy if someone needed
but here is the problem with that distribution, mirrors are not kept
long enough)
and grab the tarball from ALSA:
ftp://ftp.alsa-project.org/pub/driver/alsa-driver-0.9.0beta10.tar.bz2
<ftp://ftp.alsa-project.org/pub/driver/alsa-
driver-0.9.0beta10.tar.bz2>
2.2.2. Installation
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
warning: Christian Cardinale rf.libertysurf@elanidrac.naitsirhc
reports that he had to change 'snd-card-intel8x0' for 'snd-intel8x0',
which corresponds to what I have for my Debian system, I no longer
remember, but I think this one is the mandrake name, if it doesn't
work, just use to the other, ok?
2.3. Alsa the Debian way
I've switched to Debian some time after writing this howto and wanted
to give some instructions about it: Things may change a little
depending on which version you're using, I use Debian sarge, currently
the testing version.
2.3.1. Using a Debian package with a precompiled kernel
First of all, you can directly download the appropriate precompiled
alsa modules: find out which kernel you're using
uname -r
2.4.20-3-k7 (should be 2.4.18-k7 or something like that for a
woody/stable)
apt-get install alsa-modules-2.4.20-3-k7
the card is the "intel8x0 (PCI: Intel i810/i820/i830/i840/MX440
integrated audio)"
you should also install the recommended package alsa-utils
apt-get install alsa-utils
now, check the file /etc/alsa/modutils/0.9 against the one given
further on this howto. It may also be necessary to run update-modules
as root to ensure that these lines get into /etc/modules.conf,
although the package installation probably does it itself.
2.3.2. Using a Debian kernel source package
I was forced to recompile my kernel when I got an usb adsl modem.
(make-kpkg binary --initrd is something you want to look at someday,
but it's off topic)
I'm assuming, you've done at least the following steps:
install the alsa sources and two useful packages: apt-get install
alsa-source alsa-utils alsa-base debconf will ask you the following
questions:
Say Yes if you want to build ALSA driver with ISA PnP version.
If your computer doesn't support ISA PnP, you may say No.
Build ALSA driver with ISA PnP?
You can safely select 'no'
Say Yes if you want to build ALSA driver with debugging code.
Build ALSA driver with debugging code?
We don't need that either, so select 'no'
You can choose cards to be built by selecting cards you want.
Each selection is a same name to a option of configure script '--with-cards'.
The following list are short descriptions of the options to show what they mean.
Select cards to be built.
Select card intel8x0 (PCI: Intel i810/i820/i830/i840/MX440 integrated
audio) and exit.
cd /usr/src
tar xzvf alsa-driver.tar.gz
cd modules/alsa-driver
./configure
make && make install
now, check the file /etc/alsa/modutils/0.9 against this following one.
2.3.3. /etc/alsa/modutils/0.9
I only remember changing the cards_limit from 4 to 1, to prevent
warnings, any modification of it should be followed by running update-
modules in order to regenerate /etc/modules.conf
### DEBCONF MAGIC
# This file was automatically generated by alsa-base's debconf stuff
alias char-major-116 snd
alias char-major-14 soundcore
alias snd-card-0 snd-intel8x0
alias sound-slot-0 snd-card-0
options snd major=116 cards_limit=1 device_mode=0660 device_gid=29 device_uid=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
2.4. Kernel Approach: The AC'97 Driver
If you are using a 2.4 or later kernel you can use the Audio Codec
'97 (AC'97) <http://developer.intel.com/ial/scalableplatforms/audio/>
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
<http://www.tldp.org/HOWTO/Kernel-HOWTO.html>, 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 :-)
3. The mainboard's sensors
3.1. lm-sensors
3.1.1. Getting the drivers
Get the lm_sensors 2.6.2 or more recent: http://www.lm-
sensors.nu/archive/lm_sensors-2.6.2.tar.gz <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.
3.1.2. Installing them
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 <http://www.SuSE.de> 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.
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
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)
--------------------------------------------------------------------
3.2. lm-sensors the Debian way
This time you'll be forced to compile the modules. install the source
and programs:
apt-get install lm-sensors lm-sensors-source
The upstream lm-sensors maintainers know of a problem using
lm-sensors with IBM ThinkPad computers, resulting in
firmware corruption. If you are installing this package on
a ThinkPad, you should wait until the upstream maintainers
have solved this problem before building modules from it.
For more information, see
/usr/share/doc/lm-sensors-source/README.thinkpad.
IBM ThinkPad brokenness -- really install lm-sensors?
Answer yes to this question, you can't have an IBM thinkpad and the
k7s5a in the same box as far as I know!
cd /usr/src
tar xzvf lm-sensors.tar.gz
cd modules/lm-sensors/
make && make install
Then you should have modutils take a few arguments, the best way is
probably to use a new file, like: /etc/modutils/sensors with this
content:
alias char-major-89 i2c-dev
options it87 temp_type=0x31
run
update-modules
modprobe i2c-isa it87
You can now type sensors to access to the informations (note that you
should edit sensors.conf, otherwise you'll see strange and inaccurate
things :] )
You can also put i2c-isa and it87 in /etc/modules (one by line!) to
have them be automatically loaded on boot, I don't know yet,
how/whether it is possible to use some automatic loading/removing
process with /etc/modules.conf
3.3. Sensors.conf for the K7s5a

3.4. Sensors on 2.6 kernels
3.4.1. Kernel 2.6.1 configuration:
# Bus options (PCI, PCMCIA, EISA, MCA, ISA)
CONFIG_ISA=y
# I2C support
CONFIG_I2C=m
CONFIG_I2C_CHARDEV=m
# I2C Hardware Bus support
CONFIG_I2C_ISA=m
# I2C Hardware Sensors Chip support
CONFIG_I2C_SENSOR=m
CONFIG_SENSORS_IT87=m
3.4.2. Setting up the modules
mount sysfs pseudo filesystem if you have not done it yet.
mount -t sysfs sysfs /sys
See Documentation/filesystems/sysfs.txt and Documentation/i2c/sysfs-
interface in the kernel sources tree
modprobe it87
modprobe i2c-isa Sensors can be accessed in the sysfs pseudo file
system. But if you want you can use the lm_sensors user tools...
3.4.3. The lm_sensors user tools
Install sensors user tools:
cd lm_sensors-2.8.3
copy this into a file named chips-it87.diff
NOTE: This patch is only required for old versions of lm_sensors,

4. The mainboard's LAN adapter
4.1. Making it work...
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 to /etc/modules so it will
autoload everytime you boot:
echo "sis900" >> /etc/modules
(or echo "alias eth0 sis900" >> /etc/modutils/aliases && update-
modules for the module to be loaded when needed, go for that if you
have a Debian system)
Pay attention to the double >, or you will have troubles :]
or compile it in your kernel, where you should say Y to SiS 900/7016
PCI Fast Ethernet Adapter support in your kernel configuration.
5. Other
5.1. Knoppix
Yesterday (8/28/2003), I tried to boot with a Knoppix cd (3.2) and
found out that the computer froze during the SCSI probes.
I encountered the same problem with a more recent version (3.3).
Here is a quick way to prevent this:
When you get the knoppix prompt, add noscsi and your lang settings and
press enter:
boot: knoppix noscsi lang=fr
lang=fr is only to ensure that my language will be used even though I
overrode the append line.
5.2. Notes about parallel port networking (PLIP) and floppy bus
I recently found out several important hardware flaws on this
mainboard. For example I could not get PLIP to work properly, if
anyone has, let me know! I used a grey laplink parallel cable (also
known as Null Printer Cable) a friend sold me and followed the PLIP
Howto <http://www.tldp.org/HOWTO/PLIP.html>. I could watch activity on
the pins using a dos tool, but nothing went through, it even gave a
warning:
modprobe plip
tail /var/log/messages
kernel: plip: parport0 has no IRQ. Using IRQ-less mode,which is fairly inefficient!
kernel: NET3 PLIP version 2.4-parport pj.oc.irm@ebiing
kernel: plip0: Parallel port at 0x378, not using IRQ.
Karl said:
"I've found there is only one parallel port mode which actually
assigns an IRQ in real life (the bios believes differently) I think
its EPP but i could be wrong. I haven't used PLIP before but i thought
that this may help a little."
I still get the same warning, let me know if it ever worked.
So I had to go on with floppies, since the box didn't have a cdrom
drive, and there, I found out that the 486 had a much faster writing
speed, more than 10 seconds of difference writing exactly the same
image to the the same floppy...

I have now (with kernel 2.4.27, see below):
Jan 31 10:51:47 galicja kernel: i810: SiS 7012 found at IO 0xd800 and 0xdc0=
0, MEM 0x0000 and 0x0000, IRQ 11
[...]
Jan 31 10:51:47 galicja kernel: ac97_codec: AC97 codec, id: CMI65 (CMedia)
Earlier it was
Nov 23 06:42:36 galicja kernel: i810: SiS 7012 found at IO 0xd800 and 0xdc0=
0, MEM 0x0000 and 0x0000, IRQ 11

I just upgraded the kernel to 2.4.27 and situation is now worse: I
have no sound in xawtv, too.
If you have a similar situation, please have a look at the Alsa
drivers.

# 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.
# 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:

5.6. Some words (About BIOS)
5.6.1. Alvaro
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! :-)
5.6.2. Karl
"Also i recommend you try using either the HoneyX bios or the
CHEEPOman bios for the k7s5a instead of the official release, it gives
you more control although some problems with non-atapi CD drives (my
dvd goes crazy in linux with cheepoman)
The cheepoman bios also fixes several issues which ECS has still not
attended to.
These bios roms are unsupported by ECS please bare that in mind, also
they are meant for overclocking more than anything else, overclocking
in such a way as you don't need a pencil ;)"
