# 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/downloads/binary-tools)
|
|
* 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, we have 2 options:
|
|
|
|
* [SysReport Quirk](#sysreport-quirk)
|
|
* [UEFI Shell](#uefi-shell)
|
|
|
|
### SysReport Quirk
|
|
|
|
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](https://dortania.github.io/OpenCore-Desktop-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
|
|
|
|
### UEFI Shell
|
|
|
|
For this, we'll want ti grab [`acpidump.efi`](https://github.com/dortania/OpenCore-Desktop-Guide/tree/master/extra-files/acpidump.efi.zip) and add this to `EFI/OC/Tools` and in your config under `Misc -> Tools` with the argument: `-b -n DSDT -z` and select this option in OpenCore's picker.
|
|
|
|
If OpenCore is having issues running acpidump.efi from the boot picker, you can call it from the shell with [OpenShell](https://github.com/acidanthera/OpenCorePkg/releases)(reminder to add to both `EFI/OC/Tools` and in your config under `Misc -> Tools` ):
|
|
|
|
```
|
|
shell> fs0: // replace with proper drive
|
|
fs0:\> dir // to verify this is the right directory
|
|
Directory of fs0:\
|
|
01/01/01 3:30p EFI
|
|
fs0:\> cd EFI\OC\Tools
|
|
fs0:\EFI\OC\Tools> acpidump.efi -b -n DSDT -z
|
|
```
|
|
|
|
Once done, you should find your DSDT in the EFI/OC/Tools folder with a `.dat` extension. Rename this DSDT.dat file to DSDT.aml to help us down the line |
