Gigabyte GA-EP35-DS4, Generate C States and sound troubles

[garamond]

Hi all

I have a Gigabyte motherboard GA-EP35-DS4 (rev. 2.1) F6 bios. I created the DSDT.aml with DSDT Editor

applying the patch you have in this great site: http://Olarila.com/forum/packs.php.

Now I have a DSDT.aml that works very well in the 10.6.8. I just need the FakeSMC.kext into the folder Extra / Extensions.

But there are two problems. The first is that on the start I get the following error:

ACPI_SMC_PlatformPlugin::pushCPU_CSTData - _CST evaluation failed

ACPI_SMC_PlatformPlugin::pushCPU_CSTData - _CST evaluation failed

ACPI_SMC_PlatformPlugin::registerLPCDriver - WARNING - LPC device initialization failed: C-state power management not initialized.

I can avoid putting it NullCPUPowerManagement.kext on Extra/Extensions or adding on org.chameleon.Boot.plist the following:

GenerateCStates

Yes

GeneratePStates

Yes

I read that there is a hack _CST that can be added to DSDT.aml to avoid it in other machines. My question is if any of you know what I could use on my motherboard and where to put it into the DSDT.aml, because I have seen it not clear.

The second problem is with the sound (ALC889A). It appear the Sound control panel menus up and down and say come forth from the sound, but there is no sound in any of the outputs. In the boot log I get the following.:

Sound assertion "0 != widget->setUnsolicited ( true )" failed in AppleHDACodecGeneric at line 1153 goto handler

Sound assertion "0 != result" failed in AppleHDAWidget at line 3875 goto handler

Sound assertion "0 != widget->setUnsolicited ( true )" failed in AppleHDACodecGeneric at line 1153 goto handler

Sound assertion "0 != result" failed in AppleHDAWidget at line 3875 goto handler

Sound assertion "0 != widget->setUnsolicited ( true )" failed in AppleHDACodecGeneric at line 1153 goto handler

Sound assertion "0 != result" failed in AppleHDAWidget at line 3875 goto handler

Sound assertion "0 != result" failed in AppleHDAWidget at line 3875 goto handler

Sound assertion "0 != widget->setUnsolicited ( true )" failed in AppleHDACodecGeneric at line 1153 goto handler

Sound assertion "0 != result" failed in AppleHDAWidget at line 3875 goto handler

Any suggestions how I can fix them?.

I send the DSDT.aml if anyone knows how to improve it.

Thanks in advance.

Make sure Chameleon is loading the patched dsdt.aml (run "bdmesg" in terminal). With generate P & C states and the patched DSDT you shouldn't need NullCPUPM.

For audio, apply the ALC889a patch from here (HDEF Gigabyte) http://Olarila.com/forum/patches.php

You'll also need a patched AppleHDA.

Thanks Cassio for your help.

I think I expressed myself badly. Sorry, my English is not very good. I'm using the Chameleon-r1755-2.1svn in a hackintosh with 10.6.8 system. The DSDT.aml file is loaded.

I know the error of C-States is not serious. It is solved by putting the GenerateCStates in the org.chameleon.boot.plist.

I was wondering if there is a patch for the DSDT.aml and not have to modify the org.chameleon.boot.plist. I would like a dsdt that need as little as possible, thinking of OSX 10.7, 10.8 ....

The sound I have solved it using the VoodooHDA 0.2.56.

Let me ask you if there is a patch for my GA-EP35-DS4 that can recognize the IDE drives, without using an extension.

thank a lot

You can put _CST and _PSS in DSDT, but I think it's not worth since Chameleon does it automatically in SSDT.

For IDE you need the ATA kext, it won't work just with a DSDT patch.

Thanks Cassio

I look for an ATA kext.
