I have actually been reading a lot of the patches. I now understand how to go about adding, but how would I remove the _DSM section from GFX0 which is contained inside PCI0?

I need to make a few changes to that and I can't seem to figure that out. The way removing sections is handled confuses me.

Would this be it, with changes to match my DSDT?

 

into method label _DSM parent_adr 0x001B0000 remove_entry;
into device name_adr 0x001B0000 insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
   Store (Package (0x08)\n
       {\n
           "codec-id", \n
           Buffer (0x04)\n
           {\n
               0x88, 0x08, 0xEC, 0x10\n
           }, \n
           "layout-id", \n
           Buffer (0x04)\n
           {\n
               0x78, 0x03, 0x00, 0x00\n
           }, \n
           "device-type", \n
           Buffer (0x0F)\n
           {\n
               "Realtek ALC888"\n
           }, \n
           "PinConfigurations", \n
           Buffer (One)\n
           {\n
               0x00\n
           }\n
       }, Local0)\n
   DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))\n
   Return (Local0)\n
}
end

I don't understand what you want to change. Post the original code and what you want to patch.

[redman]

I think I figured it out. Thanks though, I may be back.

New one: How do I specify where to place something? or does it matter?

I want to take this

Device (AC)
       {
           Name (_HID, "ACPI0003")
           Name (_PCL, Package (0x01)
           {
               _SB
           })
           Method (_PSR, 0, NotSerialized)
           {
               Store (^^PCI0.LPCB.EC0.GACS (), Local0)
               Store (Local0, PWRS)
               Store (^^PCI0.LPCB.EC0.GPID (), Local1)
               If (XOr (Local0, ACST))
               {
                   \_GPE.HNLP (Zero)
                   ^^PCI0.ACEL.AJAL ()
                   \_GPE.VPUP (Local0, Local1)
                   ^^PCI0.LPCB.EC0.SMCP (Local0)
               }
               If (LOr (LAnd (Local0, LNot (ACST)), LAnd (Local1, LNot (SMAR))))
               {
                   ^^WMID.WGWE (0x03, Zero)
               }
               Store (Local0, ACST)
               Store (Local1, SMAR)
               Return (Local0)
           }
       }

 

And add this to it. Does it matter where it goes? In the dsdt I am basing this off of, it comes right after the HID section.

Name (_PRW, Package (0x02)
           {
               0x18, 
               0x03
           })

 

Also, how would I change a device name from something, say GFX0 to IGPU or AC to ADP1?

I want to edit a patch that MaLd0n gave us so everyone can use it to do this automatically.

[oldnapalm]

Just use insert, it adds at the end, the position doesn't matter

into device label AC insert
begin
Name (_PRW, Package (0x02)\n
           {\n
               0x18,\n
               0x03\n
           })
end

Check this example.

For device rename check this example.

[redman]

Yeah I figured how to add, just not how to specify where, I didn't know if it mattered. Thanks for all the help, sorry for being a bit n00bish about it, I know its frustrating. But I'm slowly getting the hang of this.

Continuing with the renaming, I want to rename the AC device listed2 posts above this.

Using this:

into device label AC set_label
begin
ADP1
end;
into_all all code_regex AC replaceall_matched
begin
ADP1
end

 

Makes my DSDT compile with errors all over.

But I don't know how to get the device address. I saw somewhere when messing with GFX0 how to do it, so I can rename that, but how could I edit the above code so it works?

[oldnapalm]

To rename the device you need just the first part

into device label AC set_label
begin
ADP1
end

The second part replaces all code_regex matches in the file, it it needed only if there are references to device AC that need to be replaced. As "AC" is a very common string you will need to refine the code_regex, something like

into_all all code_regex SB.AC replaceall_matched
begin
SB.ADP1
end

Check for compilation errors after renaming AC, if there are no errors the second part is not needed.

[redman]

What exactly does the SB. do?

[oldnapalm]

It's an example.

Let's say you get an "Object does not exist (\_SB.MOO.AC)" error after renaming AC to ADP1, then you would do

into_all all code_regex SB.MOO.AC replaceall_matched
begin
SB.MOO.ADP1
end

 

If you use just "AC" it will replace things like "0xAC" to "0xADP1" which will produce a syntax error.

I now understand. I'll try this tomorrow. Thanks!

This should be the last problem. I am trying to turn

Method (_RMV, 0, NotSerialized)
                   {
                       If (_OSI ("Windows 2009"))
                       {
                           Return (Zero)
                       }
                       Else
                       {
                           Return (One)
                       }
                   }

 

that last One into a zero.

The device this is in is called SMHC which is inside PCI0.

Why does this not work?

 

into method label _RMV device label SMHC remove_entry;
into device label SMHC insert
begin
Method (_RMV, 0, NotSerialized)\n
                   {\n
                       If (_OSI ("Windows 2009"))\n
                       {\n
                           Return (Zero)\n
                       }\n
                       Else\n
                       {\n
                           Return (Zero)\n
                       }\n
                   }\n
end

I followed the tutorial in OP for the latest Gigabyte GA-EX58 EXTREME bios from gigabyte's website, F13s. All went well but when I replaced the old DSDT.aml taken form tonycrap's DSDT database that was for F12 with the one that resulted from this tutorial, I would have no sound detected.

To note, I am not using a patched HDA, I am using HDA rollback method under 10.7.2 provided through tonycrap's multishit solution.

That said, I had 25% FPS increase in Cinebench with the new one!

Any ideas on how to restore audio?

[Cassio]

If you use patched AppleHDA you may need to update the HDEF patch according to your audio codec. Make sure layout-id in DSDT (hex) coincides with LayoutID in AppleHDA (decimal)

[table=400][trf][tdf]LayoutID (dec)[/tdf]

[tdl]layout-id (hex)[/tdl][/trf]

[tr][tdf]12[/tdf]

[tdl]0x0C, 0x00, 0x00, 0x00 = 0xC[/tdl][/tr]

[trl][tdf]889[/tdf]

[tdl]0x79, 0x03, 0x00, 0x00 = 0x379[/tdl][/trl][/table]

Thanks I ran the patch as is for my audio chipset and it worked flawlessly!

Cheers!

Would you be so kind to create a script for the Dell Vostro 3750? I tried to apply the script for the Vostro 3550 with the simplified AutoPatcher - I thought it was the same machine just with a smaller display - but that ended up in an error.

I guess you can just remove

Arg0
Arg1
Arg2
Arg3

after

Return (NVOP)

Anything after "return" will be unreachable statement anyway.

Hello.

I followed this guid to create my DSDT. My Mobo is a P8P67 Pro (rev 3.0) bios 2001, but I think it did not work as they are not recognized can the USB 3, Bluetooth and other things. What I do wrong?

[Cassio]

The patch for this mobo is available on first page.

For USB 3.0 you need PXHCD kext.

Bluetooth I have no idea.

Thanks, oldnapalm, will try.

After removing those 4 lines I could compile the dsdt.aml without errors, just got 2 warnings. Looking forward to try it, I just have to install Lion on an external hd again first.

[pilsator]

The patched dsdt didn't have any effect on screen resolution (1024x768 without any other options). The vostro also only boots with safe system start -x.

I installed iATKOS Lion with the extra-folder option checked, anything else default.
