On a few motherboards it is also possible to replace the BIOS with an updated BIOS with a patched DSDT. Then tell your bootloader to use the new DSDT file instead of the BIOS. To patch your DSDT, you must either use a new table file that someone else has provided, or extract and modify your own. For example, fixing Time Machine and the UUID 35 error is possible after modifying the DSDT. Modifying the DSDT allows the user to better support their hardware. The problem is that OS X has an incomplete ACPI implementation which supports only a subset of DSDT. These allow description of system hardware in a platform-independent manner in ACPI Machine Language (AML). The Advanced Configuration and Power Interface (ACPI) defines a large number of tables that provide the interface between an ACPI-compliant operating system and system firmware. The Differentiated System Description Table is the main table in the ACPI part of a computer’s BIOS. Quoting from the OSx86 wiki, for the Mac OSX-perspective on it, ACPI’s DSDT is: The easiest one will depend on whether you still have Windows installed, whether you already have a Linux USB stick prepared, and just how familiar you are with both systems. Just pick the method that seems easiest for you. I have included five different methods for extracting your native DSDT. SYSTEM INFO DOWNLOAD HACKINTOSH INSTALLIt is best, therefore, to patch your own DSDT and install it into /Extra/dsdt.aml (Chameleon) or EFI/Clover/ACPI/patched (Clover). Perhaps there are slight differences in BIOS settings, memory installed, etc, that is causing these differences. SYSTEM INFO DOWNLOAD HACKINTOSH HOW TOQuoting from from the beginning of RehabMan’s HP-ProBook-4x30s wiki on How to patch your DSDT (useful background even if you don’t this HP model):Īlthough there are pre-patched DSDTs available as downloads from the forums and in installer packages such as the HP ProBook Installer, there can be differences in individual DSDTs that can cause delays in booting and perhaps other problems. It contains “ Common DSDT patches for Ivy/Sandy/Haswell laptops for running OS X“, so it’s for ‘hackintosh’ hackers using non-Apple hardware to run Apple’s OS, OS X, and have to deal with non-Apple hardware/firmware, particularly ACPI’s DSDT table, a nice example of how the modding community generates some interesting firmware tools, if nothing else. I just noticed the project Laptop-DSDT-Patch, by RehabMan.
