How to use Elite's K7s5a mainboard under GNU/Linux.
|
|
</abstract>
|
|
<sect>Introduction
|
|
<p>
|
|
|
|
I got the mainboard for christmas 2001, and after a little while, I understood
|
|
that the new chipset sis735 was not handled by <url
|
|
url="http://www.mandrake.com" name="Mandrake"> 8.0,
|
|
<url url="http://www.opensound.com" name="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.
|
|
|
|
|
|
<sect>The integrated sound board
|
|
<p>
|
|
<sect1>Getting the ALSA drivers
|
|
<p>
|
|
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 <url
|
|
url="http://www.kernel.org/pub/linux/kernel/" name="http://www.kernel.org">
|
|
|
|
Here can be found Mandrake sources for the kernel used in 8.0:
|
|
|
|
<url
|
|
url="ftp://ftp.univ-savoie.fr/pub/Linux/Mandrake/8.0/i586/Mandrake/RPMS/kernel-
|
|
source-2.4.3-20mdk.i586.rpm"
|
|
name="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:
|
|
|
|
<url url="ftp://ftp.alsa-project.org/pub/driver/alsa-driver-0.9.0beta10.tar.bz2"
|
|
name="ftp://ftp.alsa-project.org/pub/driver/alsa-driver-0.9.0beta10.tar.bz2">
|
|
|
|
<sect1>Installing them
|
|
<p>
|
|
Install your kernel sources, in my case:
|
|
|
|
<em>rpm -ivh kernel-source-2.4.3-20mdk.i586.rpm</em>
|
|
|
|
Then decompress alsa drivers:
|
|
|
|
<em>bzip2 -d alsa-driver-0.9.0beta10.tar.bz2 && tar -xvf
|
|
alsa-driver-0.9.0beta10.tar</em>
|
|
|
|
Make them and install them and create the devices files:
|
|
|
|
<em>cd alsa-driver-0.9.0beta10 && make install && ./snddevices</em>
|
|
|
|
Edit <tt>/etc/modules.conf</tt> to set everything, and add to it the following
|
|
lines:
|
|
|
|
<tscreen><verb>
|
|
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
|
|
</verb></tscreen>
|
|
|
|
Paolo reports that in order to start up sensord on boot, he put in /etc/sysconfig/sensors:
|
|
<tscreen><verb>
|
|
MODULE_0=i2c-proc
|
|
MODULE_1=it87
|
|
MODULE_2=i2c-isa
|
|
</verb></tscreen>
|
|
|
|
|
|
<sect1>Kernel Approach: The AC'97 Driver
|
|
|
|
<p>
|
|
If you are using a 2.4 or later kernel you can use the <url
|
|
url="http://developer.intel.com/ial/scalableplatforms/audio/" name="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:
|
|
|
|
<em>modprobe i810_audio</em>
|
|
|
|
and you should see something like this in your syslog:
|
|
|
|
<tscreen><verb>
|
|
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
|
|
</verb></tscreen>
|
|
|
|
or type
|
|
|
|
<em>dmesg | less</em> and scroll to see the kernel messages.
|
|
|
|
If everything went fine, you may add <tt>i810_audio</tt> to
|
|
<tt>/etc/modules</tt> so it will autoload everytime you boot:
|
|
|
|
<em>echo "i810_audio" >> /etc/modules</em>
|
|
|
|
<p>or you like monolitic kernels (no modules), follow the step above to install
|
|
the kernel sources
|
|
and say Y to <tt>Sound card support</tt> and Y to <tt>Intel ICH (i8xx) audio
|
|
support</tt>
|
|
compile your kernel, install, reboot and now your integrated soundcard is
|
|
working.
|
|
|
|
If you don't know how to compile a kernel, read the <url
|
|
url="http://www.tldp.org/HOWTO/Kernel-HOWTO.html" name="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 :-)
|
|
|
|
<sect>The mainboard's sensors
|
|
<p>
|
|
<sect1>Getting the drivers
|
|
<p>
|
|
Get the lm_sensors 2.6.2 or more recent:
|
|
<url url="http://www.lm-sensors.nu/archive/lm_sensors-2.6.2.tar.gz"
|
|
name="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.
|
|
<sect1>Installing them
|
|
<p>
|
|
<em>tar -xzvf i2c-2.6.2.tar.gz</em>
|
|
|
|
<em>cd i2c-2.6.2</em>
|
|
|
|
<em>make && make install</em>
|
|
|
|
Then there was a problem when making install for me, so if it doesn't work, just
|
|
do the following:
|
|
|
|
<em>cp kernel/i2c-core.o /lib/modules/`uname -r`/misc/i2c-core.o</em>
|
|
|
|
<em>cp kernel/i2c-proc.o /lib/modules/`uname -r`/misc/i2c-proc.o</em>
|
|
|
|
Now let's copy the specific driver:
|
|
|
|
<em>cp kernel/chips/it87.o /lib/modules/`uname -r`/misc/it87.o</em>
|
|
|
|
ok now
|
|
|
|
<em>cp prog/sensors/sensors /usr/bin/sensors</em>
|
|
|
|
--------------------------------------------------------------------
|
|
|
|
|
|
Edit <tt>/etc/modules.conf</tt> and add to it the following lines:
|
|
|
|
|
|
<tscreen><verb>
|
|
alias char-major-89 i2c-dev
|
|
options it87 temp_type=0x31
|
|
</verb></tscreen>
|
|
|
|
|
|
now:
|
|
|
|
<em>modprobe i2c-proc</em>
|
|
|
|
<em>modprobe it87</em>
|
|
|
|
<em>modprobe i2c-isa</em>
|
|
|
|
<em>sensors</em>
|
|
|
|
should output you some data
|
|
|
|
When it works, you can write it to a file, that will be loaded automatically on
|
|
boot. Under <url url="http://www.SuSE.de" name="SuSE"> the file is:
|
|
<tt>/etc/init.d/boot.local</tt> (used to be <tt>/sbin/init.d/</tt>)
|
|
and you should just add: <tt>sensors -s</tt>
|
|
Under mandrake, the install should have created that file:
|
|
<tt>/etc/init.d/sensors</tt>, 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 <tt>/etc/sensors.conf</tt>
|
|
search for that line: <tt>chip "it87-*"</tt>
|
|
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)

|
|
|
|
# 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:

<sect>The mainboard's LAN adapter
|
|
<sect1>Making it work...
|
|
|
|
<p>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).
|
|
|
|
<p>To make it work you should type
|
|
|
|
<em>modprobe sis900</em>
|
|
|
|
and you should see something like this in your syslog:
|
|
|
|
<tscreen><verb>
|
|
sis900.c: v1.08.02 11/30/2001
|
|
eth0: SiS 900 PCI Fast Ethernet at 0xd400, IRQ 5, 00:d0:09:ea:7a:98.
|
|
</verb></tscreen>
|
|
|
|
or type
|
|
|
|
<em>dmesg | less</em> and scroll to see the kernel messages.
|
|
|
|
If everything went fine, you may add <tt>sis900.o</tt> to <tt>/etc/modules</tt>
|
|
so it will autoload everytime you boot:
|
|
|
|
<em>echo "sis900" >> /etc/modules</em>
|
|
|
|
or compile it in your kernel, where you should say Y to <tt>SiS 900/7016 PCI
|
|
Fast Ethernet Adapter support</tt> in your kernel
|
|
configuration.

<sect1>Some words
|
|
|
|
<p>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 <em>hdparm
|
|
-c1 -X66 /dev/hda</em>, I managed
|
|
to corrupt my filesystem, so beware.
|
|
|
|
<p>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.
|
|
|
|
<p>Good Luck! :-)
