HowTo Fix ACPI + ICH7 family (Conexant) Driver on Toshiba P100/105 series

iyatoni · 01-27-2008, 11:28 AM

Hi,

I wonder if someone could help me...

I've ran through this guide a couple of times, as I've never had any sound on my Toshiba P100 with any version of Ubuntu (currently running Gutsy).

The problem I've having is with step 6 - "$ iasl -tc -f dsdt.dsl". It appears that this command is supposed to create a 'dsdt.aml' file, but it doesn't. I've got a dsdl.hex file, and the dsdl.dsl file, but no .aml.

Am I missing something obvious here, or do I need to install something to get this working?

Thanks

Hi.
This howto is a little old and should be updated-

Please, folow the next steps:

1. Open the new dsdt.dsl file (in the editor off course) and search for all occurrences of "_T_0" (without quotes) and change them to say "T_0"(without quotes). Repeat the same steps for "_T_1" to "T_1" ....."_T_7" to "T_7" if applies in your case. A faster way to do this is to use the Search/Replace function.

2. Search for all ocurencies of: "Name (_HID, "*PNP0C14")" (without quotes) and change it to say: Name (_HID, "PNP0C14"), as you can see we only removed the star *.

3. Search for: Method (EVNT, 1, NotSerialized) and add the following at the end (before the last curly brace:
Return (Package (0x02){0x00, 0x00})

4. Search for the Method (BTST, 0, NotSerialized) and make it lokk like this (watch the last (Return Zero):

Code:

Method (BTST, 0, NotSerialized)
            {
                If (\_SB.ECOK)
                {
                    Acquire (\_SB.PCI0.LPCB.EC0.MUT1, 0xFFFF)
                    Store (\_SB.PCI0.LPCB.EC0.KSWH, Local0)
                    XOr (Local0, 0x01, Local0)
                    Store (\_SB.PCI0.LPCB.EC0.BTHE, Local7)
                    Release (\_SB.PCI0.LPCB.EC0.MUT1)
                    If (Local0)
                    {
                        ShiftLeft (Local7, 0x06, Local6)
                        ShiftLeft (Local7, 0x07, Local7)
                        Or (Local7, Local6, Local1)
                        Or (Local0, Local1, Local2)
                        Return (Local2)
                    }
                    Else
                    {
                        Return (Zero)
                    }
                }
              Else
                    { Return (Zero) }
              }
        }

5 Search for: Method (_INI, 0, NotSerialized)
and comment add add as shown:

Code:

/*If (CondRefOf (_OSI, Local0))
            {
                If (_OSI ("Linux"))
                {
                    Store (0x03E8, OSYS)
                }
                Else
                {
                    Store (0x07D1, OSYS)
                    If (_OSI ("Windows 2001 SP2"))
                    {
                        Store (0x07D2, OSYS)
                    }

                    If (_OSI ("Windows 2001.1"))
                    {
                        Store (0x07D3, OSYS)
                    }

                    If (_OSI ("Windows 2001.1 SP1"))
                    {
                        Store (0x07D4, OSYS)
                    }

                    If (_OSI ("Windows 2006"))
                    {
                        Store (0x07D6, OSYS)
                    }

                    If (LAnd (MPEN, LEqual (OSYS, 0x07D1)))
                    {
                        TRAP (0x3D)
                    }
                }
            }*/
        Store (0x07D6, OSYS) // Fake Windows 2006

Save your file
6. in a terminal run the next command (you must be in the same direcotry of the document of course)

$ iasl -tc dsdt.dsl:

Then follow Duchty's instructions regarding Ubuntu (Post # 11)

and forget about compiling ALSA, this step is not necesary anymore

Hope to be of help
Regards

I kinda gave up already (finding it all out is way above my head). I too will try the new steps some time

Either that or im waiting till it's fixed completely

The good news is that the new kernel, 2.6.24 is making things easier, you must not change anything at all, everything works just right out of the box

.

I tried the Mandriva spring release (2008.1) and I had to do nothing, I was so sorprised that when I decompiled a new DSDT I just saw that everythig was just exactly as my own changes ... those are really good news

Hello everyone. I have a problem with My toshiba P100-257. I use MacOS X 10.5.4 (iATKOS hackintosh). The problem is that I can't get my sound working. The situation is very strange. I used several hacked BIOSes - 4.00-4.30 from different P-100(-105) Toshibas. I've found BIOS that makes my sound work. BUT it works ONLY with 512mb memory banks. When I install 2Gb memory banks (EVEN one 2Gb bank) my sound disappeares. Can anyone help me to solve this problem? Or at least give an advice, please.

Thanks for Your attention.

With great respect, minos.

Hi minos, the problem described in this thread was fixed in recent kernels.

Also, hackintosh is not supported here.
