Satellite P100-324 custom DSTD for sound in Linux needed
Posted: 10-Apr-2007 19:56

IÂ´ve posted original DSTD dump on site http://acpi.sourceforge.net/dsdt/view.php?id=771
I donÂ´t have knowledge to edit it by myself, so i canÂ´t correct it.

Now iÂ´m without sound with this bios version (v3.30). forcing acpi off leads to more serious errors on my OS.
Does anybody know the way this file should be modified to get sound working?

Im have the same Problem on P100-439. This is a Bug in the BIOS-Version 3.30!!! That is very annoying. No Linux distribution functions. I hope that this is very fast changed.

Is this really a bug? I think it´s just not really good supported by linux if you ask me. But ok, other people have other opinions...

I regard this as a bug in BIOS, too.
The DSDT is part of the BIOS, not of the operating system. But it is possible to override a corrupt DSDT with the Operating System.

If you try to compile the original source of the P100-429 DSDT with the Intel iasl, you receive quite a number of errror messages and warnings.
After fixing the source manually and compiling again, there will be no errors and no warnings.
With the manually repaired DSDT manually included in the initial ramdisk of your actual Linux Kernel, sound and acpi works fine.

The Bug is not fixed by Toshiba in the BIOS version 3.5

Toshiba fixed DSDT-Bugs that showed effects in Windows, but nothing more.
The answers of the Toshiba support in this regard are less than unusable.
Toshiba seems not to be not able and/or not willing to fix the DSDT in BIOS.

It's remarkable that the community is able and willing to show a way to rapair the DSDT.

Hello vug

Toshiba support can not tell you much about those details because Toshiba does not support Linux. Unfortunately BIOS is designed for WXP or Vista now and you can not write about any bugs or something similar.

I know very well that many people use Linux or Linux and Windows preinstalled on the same notebook but the fact is that Linux is not supported OS. If you have time visit follow sites:

I don't request for Linux support, I just request for a BIOS without errors. !

Whether Linux is supported or not...the DSDT bug is, as far as know, a bug in the BIOS of the Laptop and not a bug in a special operating system.

If is possible to design a BIOS for Vista, why should'nt it be possibe to design a BIOS without bugs ??
The bug is well-documented, reproducible and anybody may use the workaround. But Toshiba refuses to fix the code of the DSDT in BIOS as long it doesn't
breed unwanted behavior in Vista.
Assumed they are able to desing bug-free BIOSes, why are they not willing to do that ?

@renewehle
You can contact the ASP in your country to make some complaints but I don’t really understand your point of view. The Linux is not supported by Toshiba! If you want you can install everything on the notebook but don’t wonder if it will not run…

Sorry to say it but Windows works great on this unit and with this BIOS…

Finally, I’ve got it.
After 5 hours of googling, reading, discovering, recompiling and restarting, it works like a charm.
I posted corrected DSDT.aml here>
http://acpi.sourceforge.net/dsdt/view.php?id=779

About the beginning flame... I didn't mean to start it.
I’ve already corrected error for my own notebook, so my point of view maybe changed a little bit, but one thing is clear:
1, Toshiba supports only MS OS - ok
2, Toshiba’s BIOSes has bugs that show effect only on non-MS operating system – ok. They don't MUST to correct it, but it would be good for both sides.
