+
+## Finding the ACPI path
+
+Finding the ACPI pathing is quite easy actually, first open your decompiled DSDT you got from [Dumping the DSDT](/Manual/dump.md) and [Decompiling and Compiling](/Manual/compile.md) with either maciASL(if in macOS) or any other text editor if in Windows or Linux(VSCode has an [ACPI extension](https://marketplace.visualstudio.com/items?itemName=Thog.vscode-asl) that can also help).
+
+Next, search for the following:
+
+* Finding the LowPinCount path:
+  * Search `Name (_ADR, 0x001F0000)`
+* Finding the PCI path:
+  * Search `PNP0A08` (If multiple show up, use the first one)
+
+You should get something like the following show up:
+
+LPC Pathing          |  PCI Pathing
+:-------------------------:|:-------------------------:
+![](/images/Universal/nvram-md/lpc.png)  |  ![](/images/Universal/nvram-md/pci0.png)
+
+Now with the pathing, you can head here: [Edits to the sample SSDT](#edits-to-the-sample-ssdt)
+
+## Edits to the sample SSDT
+
+Now that we have our ACPI path, lets grab our SSDT and get to work:
+
+* [SSDT-PMC.dsl](https://github.com/acidanthera/OpenCorePkg/blob/master/Docs/AcpiSamples/SSDT-PMC.dsl)
+
+By default, this uses `PCI0.LPCB` for the pathing. you'll want to rename accordingly.
+
+Following the example from above, we'll be renaming it to `PCI0.LPC`:
+
+**Before**:
+
+```
+External (_SB_.PCI0.LPCB, DeviceObj) <- Rename this
+
+Scope (_SB.PCI0.LPCB) <- Rename this
+```
+
+![](/images/Universal/nvram-md/ssdt-before.png)
+
+Following the example pathing we found, the SSDT should look something like this:
+
+**After**:
+
+```
+External (_SB_.PCI0.LPC, DeviceObj) <- Renamed
+
+Scope (_SB.PCI0.LPC) <- Renamed
+```
+
+![](/images/Universal/nvram-md/ssdt-after.png)
+
+## Compiling the SSDT
+
+ With the SSDT done, you're now [ready to compile the SSDT!](/Manual/compile.md)
+
+## Wrapping up
+
+Once you're done making your SSDT, either head to the next page to finish the rest of the SSDTs or head here if you're ready to warp up:
+
+* [**Cleanup**](/cleanup.md)
