DSDT patch help

[PPCnostalgic]

Hi there. I've installed Mac OS Sierra 10.12.2 on a Dell Precision T3500 (no dsdt yet) Xeon W3550 Nvidia Quadro2000 12Gb DDR3. Everything work but for AppleLPC.kext doesn't load. I extracted the raw dsdt on Windows running    RW - Read & Write and saved the file as binary. Now it needs patches to make it usable on Mac OS X but I'm not able to do it. Can someone help me please?

Thank you.

DSDT.bin.zip

[foskvs]

iasl -d DSDT.bin

or if you want a "legacy" output

iasl -d -dl DSDT.bin

You can download iasl from Github (acpica or one of its forks)

[PPCnostalgic]

Ok, downloaded. Can I use it in Mac OS X terminal or what else?

Yes, you need to install it to /usr/bin

sudo cp path_to_iasl/iasl /usr/bin/iasl

Edit:

 

If you downloaded the source code, you need to compile it with make + make install (or download this binary).

 

iasl.zip

[PPCnostalgic]

I'm not familiar with these command lines, please tell me what app I can use by simply choosing "save as". Again, sorry for my ignorance.

[foskvs]

An editor with iasl included, like MaciASL. But i suspect MaciASL need .aml files...

Extract Acpi all your tables with Clover (F4 at gui).

 

Edit:

 

yep:

I extracted your DSDT to .dsl format, but IMHO i would not use it (it has very strange errors).

DSDT.dsl.zip

[MaLd0n]

just rename .bin to .aml and apply patches, u can use .txt too, just rename

DSDT.aml.zip

 

i apply some essentials patches, post one ioreg for a full solution

[PPCnostalgic]

Ok, I'm testing your DSDT,, thank you. I extracted a dsdt table with MaciASL see attachment

System DSDT.zip

[MaLd0n]

is a same table principal bios table

[PPCnostalgic]

Ok, IOREG file in attachment

Clover config.plist

 

BTW Tried he DSDT posted by MaLd0n, the AppleLPC kext does load but the PC doesn't shut down, the screen turns off but the PC doesn't power off 

Dell T3500.zip

config.plist.zip

[MaLd0n]

LPC is load, is device ISA in ur case

ill check ioreg and dsdt, wait me

the shutdown in ur case, i think need a PMBASE

[MaLd0n]

Try

DSDT.02.zip

send me new ioreg after reboot, the tables missing many devices, i add many, need check

[PPCnostalgic]

Ok, new IOREG file after reboot with your DSDT

[MaLd0n]

Ok, new IOREG file after reboot with your DSDT

Shutdown work?

what ur audio codec?

[PPCnostalgic]

Yes, shutdown works! As for audio I'm using Voodoo HDA and it works properly. You did it, thank you very much. I'm still testing the machine and I'll post about issues -if any- but it seems to work properly.

device HDEF is created, i add id 1, use AppleAlc + Lilu kexts instead VoodooHda and AppleHdadisabler

try a native audio

Audio.zip

sleep work?

[PPCnostalgic]

Yes Sir, sleep works too. Should I remove Voodoo before trying your audio kexts ?

[MaLd0n]

ye, u need remove Voodoohda.kext and applehdadisabler.kext too, after remove kexts run kextutility

Kext Utility.app.zip

 

the two kexts above, u can use in Clover/Kexts/Others

[PPCnostalgic]

Native audio didn't work, but Voodoo works fine so no problem at all. A strange thing I didn't notice is a weird system behaviour with RAM. I mean this machine has 6x 2Gb DDR3 installed so there are no empty slots, 12 Gb but the system reports 8,61 Gb as wired memory with no apps opened.... too much ain't it?

BTW the memory issue I think was present even before you edited the dsdt. A big thank you for your support.

 

EDIT: nevermind, I had 2 Defective ram sticks, everything works properly

[MaLd0n]

try with DPCI Manager and check if u see ur audio codec

about memory is a clover, u use last version?

Clover_v2.4k_r4390.pkg.zip

u can try solve it in config.plist/smbios tab

[PPCnostalgic]

Thank You MaLd0n, the memory is right now, I trashed those 2 defective sticks and put other 2 and now everything works! As for the audio I think I'll stay with Voodoo because it manages audio working even via HDMI on the graphic card, plus I'm using an external good USB audio card.

So when a proper DSDT is installed can we use a native CPUPowerManagent kext? I'm asking because on my HP Z400 (signature) everything works but for the CPUPowerManagement kext and I need to use a patched one (ver 216 from Yosemite). Again thank you for all your support.

[MaLd0n]

let's try a native audio

download it

http://www.insanelymac.com/forum/files/file/496-applehda-patcher/

[PPCnostalgic]
