Before writing a PC-mounted Mac OS x system, the most tangled thing in the preparation is the driver. On the network to search for other people to release the driver, unfortunately, many times can not solve their own various inexplicable problems. Fortunately now with the IDSDT this artifact, graphics card can work perfectly, easy to handle.
This article applies to you still have the Windows system, and has installed the Mac OS x system, just under the Mac system part of the hardware is not working properly, can effectively solve the problem of unable to change the resolution, no sound and other incurable diseases.
1. Download the required software
- EVEREST Ultimate Edition (very professional hardware testing software,)
- Gpu-z (very professional graphics card detection software,)
- IDSDT Software (tool for generating DSDT files, running under Mac System)
2. Extracting the motherboard BIOS information
Open the software we just downloaded EVEREST Ultimate Edition, in the software's status bar (or right-click the InfoBar, select the ACPI tool)
A whole bunch of messages will appear, and we'll ignore him. Save DSDT directly by saving
Here we have the BIOS file of our motherboard, OK close the software.
3. Extracting video card rom files
Open the Gpu-z software we just downloaded, the software interface is as follows:
Click on the Green button and then click Save As File. Note that the gpu-z default saved video card rom file extension is bin, but the format recognized by the IDSDT software is ROM, so after saving to change the file name extension rom
4. Extracting sound card codec file
The codec is a small chip that is designed to handle signals and analog inputs and outputs. The purpose of the codec file is to describe the location of each interface of your sound card, and we can use this codec file to make our counterfeit drive.
You need a Linux system to accomplish this task. Ubuntu is currently one of the most popular Linux versions and is relatively easy to get started with. You can go to the official download an image, engrave a disc, and then insert the disc into the system without installing to the hard drive. After successfully entering the desktop, look for the/proc/asound/folder from the system partition, and then you will see the card0 Card1 folder, perhaps more or less, in these folders looking for a file named Codec#.txt, copy save.
If you feel trouble, then go to the Vision forum to see if anyone has shared their codec.txt, just like your sound card model. But I still have plenty to do with my own hands.
5. Final generation of DSDT files using IDSDT
Enter the Mac system, open the IDSDT software, the interface is as follows:
- Import DSDT file-Our second step to extract the motherboard rom file
- Import video card rom file-Our third step is to extract the video card rom file
- Import sound card Codec file-Our fourth step to extract the sound card codec file
Don't forget to give your graphics card a name, and the last point is "start generating". The IDSDT image contains detailed instructions. This is the Chinese people write software, admire AH ~ generated DSDT file directly placed in the system/extra folder, the Chameleon boot will automatically load when booting.
DSDT is a file that describes your hardware, it doesn't drive the hardware, it just tells your Mac system what's on your motherboard, but your operating system doesn't support a piece of hardware, and even if you use the correct DSDT file, you may not be able to drive your video card. If DSDT can not solve, in addition to the bitter force to find kext Drive, or to buy a new machine to install Mac it ...
