Chameleon dsdt file

Then use it during disassembly:. After disassembly, you may want to look at the content of each. Certain patching is dependent on the content. And renaming is best accomplished via config. For the most part, you should be focused on only DSDT. Even by disassembling all at once iasl with -da option , the native files can still have errors.

The disassembled files have errors due to changes in iasl over time, imperfections in iasl itself, and differences in the compilation environment between our laptops and the OEM. There is also clearly cases where bugs are in the code or code was written uninitentionally sometimes hard to tell the difference.

There are many common patches for such errors in my laptop patch repository for MaciASL. It has too many bugs and a very old version of iasl. Please do not ask me about it. In order to determine which patch you need, you can look at the error message coming from the iasl compiler and the code at the line the error was detected. You can also attempt to apply a patch just to see if it makes changes as shown in the Preview window in MaciASL.

For some errors, you can simply remove the line of code causing the error. But, it depends on whether the line is necessary for proper operation of the code or not. For example, errors caused by 'External' declarations can generally be removed to fix the error. If you wish, you can create automated patches of your own to remove these lines.

It helps to have some experience with the ACPI spec and some programming experience. Your goal is to get each. Once you have files that compile without errors, you can move on to patching them to fix issues you may have with your OS X installation. The fix is to simply comment out the related External declarations. It is a very common error caused by an iasl bug. I'm not going to add a MaciASL patch for it, since it will eventually be fixed by Intel it is a regression.

Store Zero, F0LN. Generally, a DSDT patch should only be applied after finding a need for that specific fix. But there are several patches that are commonly needed and that have only a small chance of causing a problem. They are in my laptop repo and are listed here:. Note: The OS Check Fix patch you use has nothing to do with the version of Windows the laptop came with, nor with the version of Windows you're currently using.

These patches can be used to inject power properties for USB:. Note regarding renames: Renames must be "balanced. This is why renames are best accomplished with config. Note regarding duplicate identifiers: You must be sure that your patched files do not contain duplicate identifiers. Problem specific patching. When following a guide for a specific laptop, it may instruct you to apply a patch that is provided in the post itself.

You will recognize it as the syntax used will look similar to other patches you've seen in the repository eg. These patches are intended to be pasted directly into the patch window in MaciASL so they can be applied. Patches for using patched AppleHDA. With patched AppleHDA, there are two patches that are needed in conjunction with the kext:.

Note that you must have an AppleHDA that matches your codec, and must determine which layout-id was chosen. The layout-id is an arbitrary choice by the creator of the patched AppleHDA. To determine the layout-id used by a particular patched AppleHDA: First you need to know your codec id in decimal eg. Then look in the Info. The LayoutID that matches your codec id is the layout id you need.

It is possible that a patched AppleHDA contains more than one layout-id for a given codec. In that case, choose the one you want to use. Saving files for loading by the bootloader. Each bootloader location is unique and has different requirements for naming. This guide and other guides linked from this guide assumes you are using config. Other configurations are covered below in "Recommended configurations". By setting config.

Perhaps due to not reading the license or a one line fix, the release of code is required - a derived project is subject to the same license as the original. End users who see projects using Chameleon code should ask for the source - or those projects should not release binaries to the public at all. Chameleon is a bootloader. It loads right after the bios sets up the computer and tries to find an operating system to start. Chameleon is an evolution of David Elliot's dfe original modification of Apple's own boot Chameleon is comprised of a series of loaders:.

Available media is scanned for an overview of available operating systems. For example, some motherboards are better supported than others - stemming from their similarity to components within existing Apple computers. Some components do not have a corollary to a Mac components, and so additional software needs to be included kernel extensions for a particular audio or ethernet chip for example.

Other components like graphics don't have much 3rd party support, requiring a selection that sticks to existing product lines that are known to be supported.

There is 1 file that configures how Chameleon behaves the com. Of these, only kernel extensions are required to start Mac OS X, the other files are optional.

Extra folder on a Preboot. Kernel extensions in either stand-alone. Only 1 com. Its is best to pick a single location for all files. This is the a simple text file with few parameters. Mostly this information is reflected in system profiler information. This file is in an extended XML format called a property list or plist as the suffix shows. The human readable quasi-programming DSDT. Amending this file can support or add support in ways that make your computer more stable - or less stable if the coding is not done properly.

Adding support for an audio chip can be done by chaining a few lines, but support can also come in the form of a kernel extension, so it can be a matter of preference. Chameleon uses this file as a preferences file - many aspects of Chameleon can also be configured by adding them in key::string form into this file. System-specific features are also entered here in the form of device properties for inclusion into the EFI tree that Chameleon presents to the kernel. Search for a guide to "EFI strings".

They extend OS support to additional components a LAN chip , remedy components that work, but imperfectly an audio chip , or nullify existing Apple components that cause problems like CPU power management. From the deadmoo image which erased my entire family album LOL I had a backup to installing OS X from a retail and running it without touching the system!!! Now we are closer than ever to a real Mac. The potential this has is extremely overwhelming. Desktop users will no longer get overheating and laptop users will get better battery life and improved performance.

I can't wait to see what this will develop into. When we say we're getting closer to a real Mac, we mean functionally not structurally. And by the way, there isn't much difference between PC and Mac hardware at all. Mac use the standard Intel mobile chipsets used is all other laptop brands Dell, Acer, Toshiba It's not like the PPC days anymore. For educational purposes only This dump even contains the cst cstates and ist pstates that are usually hard coded into the memory of the BIOS?

Thanks for your help. Great work as always!! VoodooPower speedstep never seem them. I Think this would be very interesting, if it solves sleep problems not due graphics cards on hackintosh! The only problem i have is when i shutdown the laptop, it restarts, This has been my nightmare since For a real-world example, you can read my posting Technical details of my Hackintosh installation.

Fix permissions and ownership of the kernel extensions. Chameleon supports overriding the DSDT provided by your hardware with a version loaded prior to loading the operating system. Mac version [17] is also available. The iasl binary is stored in the Tools directory of the linked download. Just run. Many of these patches are quite generic.
