This article let you know how to make DSDT patches in config.plist. DSDT consists of bunch of Hex codes that we don't understand at all. IASL translate these hex codes into understandable text results in aml file. We don't need to know all of combination of hex codes. I am concentrating on Method, Device and Name which are enough for patching dsdt.

1. make ssdt.dsl to find out which is what.

Here is simple test.dsl. I got this code from one of my ssdt files.

I assume you have iasl file in your /usr/bin directory. 

Open terminal and execute following command " iasl -l test.dsl ". There are two files that would be showed up. test.aml and test.lst.  lst file is important. Open test.lst with Text Edit application. You can see text and hex codes together like this.

As you can see the sample, you can understand which reserved words are what.

Name starts with 0x08, Method starts with 0x14and Device starts with 0x5B, respectively. 

This will help you when you patch device name or method correctly and let you know which hex code should be included or started in order to make sure you have only one choice for special case.

One more thing. If you want to patch name, you should know hex number of each text. This is simple.

Let's say, you are trying to patch SBRG to LPCB. Open terminal and execute following this command.

 You don't need to website to translate this. xxd command will solve this problem.

2. DSDT patches in config.plist

Here is the sample from my config.plist.

This sample patches Name (SS3, Zero) to Name (SS3, One). Hex code starts with 08 as we found out the above.

Because there are several SS3 in the dsdt.aml, I need to narrow down one match exactly what I want like below.

The most important point of hex patching including DSDT, info.plist is that patch same bytes. If not, hex patching is not working at all. Name patching can be executed multiple times. 

I hope this would be helpful.
