[Guide] Patching LAPTOP DSDT/SSDTs

[Wong98]

Rehabman, is it possible for you to make a youtube video about how to patch DSDT. It will make me understand easier from video. Appreciate a lot for that.

Read post #1 for correct disassembly and correct MaciASL setup (ACPI 5.0).

Post ACPI/origin if you need help.

I do it again and now I get this from dsdl.dsl . How to fix?

When I open a .txt file in patch, the apply button grey out (cannot apply). Why?

Nothing is attached. Post ACPI/origin.

Sorry I forget it.

Nothing unusual here...

Correct disassembly: iasl -da -dl DSDT.aml SSDT*.aml

DSDT.dsl: Apply "Fix PARSEOP_ZERO Error" and "Fix ADBG Error". Result: no errors.

SSDT-1.dsl: Apply "Remove _PSS placeholders"

SSDT-9.dsl: Apply "Cleanup/Fix Errors (SSDT)"

You mean apply those patches into the specific .dsl(it's .aml is extract with linux).

Also, the origin I attached is from EFI Partition. Is that correct ? Because I cannot apply some patch(example : graphics_PNLF_haswell.txt) to DSDT.dsl(it's .aml is extract with linux)

Use the Clover F4 extract that you provided here.

"Brightness Fix (Haswell/Broadwell)" usually is not applied to DSDT. You should read the guide carefully.

I´m a newbie at this.

When I try to compile the dsdt file i get an error:
6201, 6126, syntax error, unexpected PARSEOP_SCOPE, expecting $end and premature End-Of-File

Scope (_PR)
{
Processor (CPU0, 0x01, 0x00000410, 0x06) {}
Processor (CPU1, 0x02, 0x00000410, 0x06) {}
Processor (CPU2, 0x03, 0x00000410, 0x06) {}
Processor (CPU3, 0x04, 0x00000410, 0x06) {}
Processor (CPU4, 0x05, 0x00000410, 0x06) {}
Processor (CPU5, 0x06, 0x00000410, 0x06) {}
Processor (CPU6, 0x07, 0x00000410, 0x06) {}
Processor (CPU7, 0x08, 0x00000410, 0x06) {}
}

Attached are my native dsdt extracted from linux and IOreg file.

I want to patch the audio by the DSDT-method in the post
http://www.tonymacx86.com/audio/185320-help-realtek-alc-255-general-question-about-install.html

I have the error below when patching the DSDT.dsl.
syntax error: unexpected $end and premature end of file

Can anyone help me correct the error?

It is caused by a conditional.

Change:

                If (Or (_OSI ("Windows 2006"), _OSI ("Windows 2009")))
                {
                    Device (MBT)
                    {
                        Name (_HID, EisaId ("PNP0C32"))  // _HID: Hardware ID
                        Method (GHID, 0, NotSerialized)
                        {
                            Return (Buffer (One)
                            {
                                 0x02                                           
                            })
                        }
                    }
                }

To:

                //If (Or (_OSI ("Windows 2006"), _OSI ("Windows 2009")))
                //{
                    Device (MBT)
                    {
                        Name (_HID, EisaId ("PNP0C32"))  // _HID: Hardware ID
                        Method (GHID, 0, NotSerialized)
                        {
                            Return (Buffer (One)
                            {
                                 0x02                                           
                            })
                        }
                    }
                //}
