# Getting a copy of our DSDT
|
|
|
|
So to start, we'll need to get a copy of your DSDT from your firmware. The easiest way is grabbing the DSDT.aml SSDTTime dumped for us earlier but here are some other options:
|
|
|
|
|
|
|
|
|
|
**From Windows**:
|
|
|
|
* [SSDTTime](https://github.com/corpnewt/SSDTTime)
|
|
* Supports both Windows and Linux for DSDT dumping
|
|
* `4. Dump DSDT - Automatically dump the system DSDT`
|
|
* [acpidump.exe](https://acpica.org/sites/acpica/files/iasl-win-20180105.zip)
|
|
* In command prompt run `path/to/acpidump.exe -b -n DSDT -z`, this will dump your DSDT as a .dat file. Rename this to DSDT.aml
|
|
|
|
* Do note that all ACPI patches from clover/OpenCore will be applied to the DSDT with the above 2 methods
|
|
|
|
**From Linux**:
|
|
|
|
* [SSDTTime](https://github.com/corpnewt/SSDTTime)
|
|
* Supports both Windows and Linux for DSDT dumping
|
|
* `4. Dump DSDT - Automatically dump the system DSDT`
|
|
* Do note that all ACPI patches from clover/OpenCore will be applied to the DSDT with the above method
|
|
|
|
**From Clover**:
|
|
|
|
For those with Clover installed previously, this is a simple way to get your ACPI tables:
|
|
|
|
* F4 in Clover Boot menu
|
|
* DSDT can be found in `EFI/CLOVER/ACPI/origin`, the folder **must** exist before dumping
|
|
|
|
**From OpenCore**:
|
|
|
|
With OpenCore 0.5.9, we have a new quirk called SysReport which will actually dump our DSDT automatically when hitting the boot screen. The main issues are:
|
|
|
|
* You already need a bootable OpenCore USB to get this dump
|
|
* This also requires a DEBUG version of 0.5.9
|
|
|
|
For the latter, you just need to replace the following files with [DEBUG version](https://github.com/acidanthera/OpenCorePkg/releases):
|
|
|
|
* EFI/BOOT/
|
|
* `BOOTx64.efi`
|
|
* EFI/OC/Bootstrap/
|
|
* `Bootstrap.efi`
|
|
* EFI/OC/Drivers/
|
|
* `OpenRuntime.efi`
|
|
* EFI/OC/
|
|
* `OpenCore.efi`
|
|
|
|
For the former, you can actually skip the ACPI section, return to the OpenCore guide([Desktop](https://dortania.github.io/OpenCore-Desktop-Guide/), [Laptop](https://dortania.github.io/vanilla-laptop-guide/)) and finish making the USB. Once booted to the picker, you can shut off the PC and check your USB:
|
|
|
|
|
|
|
|
And voila! You have a DSDT! Now you can continue on with making SSDTs
