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) -------------------------------------------------------------------- <tscreen><verb> chip "it87-*" # The values below have been tested on Asus CUSI, CUM motherboards. # Voltage monitors as advised in the It8705 data sheet label in0 "VCore" label in1 "Vcc2.5v" label in2 "Vcc5v" label in3 "+5V" label in4 "+12V" label in5 "-12V" label in6 "-5V" label in7 "SB 5V" label in8 "V battery" set in0_min 1.7 * 0.95 set in0_max 1.7 * 1.05 set in1_min 2.4 set in1_max 2.6 set in2_min 3.3 * 0.95 set in2_max 3.3 * 1.05 set in3_min 5.0 * 0.95 set in3_max 5.0 * 1.05 set in4_min 12 * 0.95 set in4_max 12 * 1.05 set in5_min -12 * 0.95 set in5_max -12 * 1.05 set in6_min -5 * 0.95 set in6_max -5 * 1.05 set in7_min 5 * 0.95 set in7_max 5 * 1.05 # vid not monitored by IT8705F ignore vid # For this family of chips the negative voltage equation is different from # the lm78.

It is really up to you. Search Google or OC Workbench and you'll be on your way. <p>Good Luck! :-) <!-- End of document --> </article>
