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 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 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 :] Sbastien

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 resample, whereas Alsa does it perfectly.

2.2 Alsa

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 Here can be found Mandrake sources for the kernel used in 8.0: ftp://ftp.univsavoie.fr/pub/Linux/Mandrake/8.0/i586/Mandrake/RPMS/kernel 6. Contributions 2

The Elite's K7s5a mainboard HOWTO source2.4.320mdk.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.alsaproject.org/pub/driver/alsadriver0.9.0beta10.tar.bz2

Installation

Install your kernel sources, in my case: rpm ivh kernelsource2.4.320mdk.i586.rpm Then decompress alsa drivers: bzip2 d alsadriver0.9.0beta10.tar.bz2 && tar xvf alsadriver0.9.0beta10.tar Make them and install them and create the devices files: cd alsadriver0.9.0beta10 && make install &&./snddevices Edit /etc/modules.conf to set everything, and add to it the following lines:
alias alias alias alias alias alias alias alias alias charmajor116 snd charmajor14 soundcore soundslot0 sndcard0 soundservice00 sndmixeross soundservice01 sndseqoss soundservice03 sndpcmoss soundservice08 sndseqoss soundservice012 sndpcmoss sndcard0 sndcardintel8x0
warning: Christian Cardinale rf.libertysurf@elanidrac.naitsirhc reports that he had to change 'sndcardintel8x0' for 'sndintel8x0', 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.
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 Installation 3
The Elite's K7s5a mainboard HOWTO 2.4.203k7 (should be 2.4.18k7 or something like that for a woody/stable) aptget install alsamodules2.4.203k7 the card is the "intel8x0 (PCI: Intel i810/i820/i830/i840/MX440 integrated audio)" you should also install the recommended package alsautils aptget install alsautils now, check the file /etc/alsa/modutils/0.9 against the one given further on this howto. It may also be necessary to run updatemodules as root to ensure that these lines get into /etc/modules.conf, although the package installation probably does it itself.
Using a Debian kernel source package
I was forced to recompile my kernel when I got an usb adsl modem. (makekpkg 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: aptget install alsasource alsautils alsabase 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 'withcards'. 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 alsadriver.tar.gz cd modules/alsadriver./configure make && make install
The Elite's K7s5a mainboard HOWTO now, check the file /etc/alsa/modutils/0.9 against this following one.

/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 updatemodules in order to regenerate /etc/modules.conf
### DEBCONF MAGIC # This file was automatically generated by alsabase's debconf stuff alias charmajor116 snd alias charmajor14 soundcore alias sndcard0 sndintel8x0 alias soundslot0 sndcard0 options snd major=116 cards_limit=1 device_mode=0660 device_gid=29 device_uid=0 alias alias alias alias alias soundservice00 sndmixeross soundservice01 sndseqoss soundservice03 sndpcmoss soundservice08 sndseqoss soundservice012 sndpcmoss
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) 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 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. /etc/alsa/modutils/0.9 5
The Elite's K7s5a mainboard HOWTO 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 :)
3. The mainboard's sensors 3.1 lmsensors

Getting the drivers

Get the lm_sensors 2.6.2 or more recent: http://www.lmsensors.nu/archive/lm_sensors2.6.2.tar.gz You'll need kernel sources too in order to compile that one.

Installing them

tar xzvf i2c2.6.2.tar.gz cd i2c2.6.2 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/i2ccore.o /lib/modules/`uname r`/misc/i2ccore.o cp kernel/i2cproc.o /lib/modules/`uname r`/misc/i2cproc.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 charmajor89 i2cdev options it87 temp_type=0x31
now: modprobe i2cproc modprobe it87 modprobe i2cisa 3. The mainboard's sensors 6
The Elite's K7s5a mainboard HOWTO 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. Paolo reports that in order to start up sensord on boot, he put in /etc/sysconfig/sensors:
MODULE_0=i2cproc MODULE_1=it87 MODULE_2=i2cisa
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 lmsensors the Debian way
This time you'll be forced to compile the modules. install the source and programs: aptget install lmsensors lmsensorssource
The upstream lmsensors maintainers know of a problem using lmsensors 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/lmsensorssource/README.thinkpad. IBM ThinkPad brokenness really install lmsensors?
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 lmsensors.tar.gz cd modules/lmsensors/ 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:
The Elite's K7s5a mainboard HOWTO run updatemodules modprobe i2cisa 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 i2cisa 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

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/sysfsinterface in the kernel sources tree modprobe it87 modprobe i2cisa Sensors can be accessed in the sysfs pseudo file system. But if you want you can use the lm_sensors user tools.
The lm_sensors user tools
Install sensors user tools: cd lm_sensors2.8.3 copy this into a file named chipsit87.diff NOTE: This patch is only required for old versions of lm_sensors, Paolo wrote: "A reply from lm_sensors developers said that the next version of lm_sensors will fix this. It is already fixed in CVS."

4. The mainboard's LAN adapter 4.1 Making it work.
If your board came with the optional onboard 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 && updatemodules 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. 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 IRQless mode,which is fairly inefficient! kernel: NET3 PLIP version 2.4parport 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.
5.3 Notes about mainboard replacement

If you have a similar situation, please have a look at the Alsa drivers.

5.6 Some words (About BIOS)

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! :)
"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 nonatapi 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 ;)"
I was pretty surprised by the number of mails I received about this howto. Unfortunately I lost several contributions when my hard drive died but I'm always listening, so don't hesitate to mail us. Seb
