-This SSDT is required for all "true" 300 series motherboards and newer(Z370 is excluded), it specifically brings back NVRAM support and requires very little configuration for the end user.

-Oddly enough, desktop Z490 boards **DO NOT** need this SSDT. NVRAM just works out of the box for most users, if there's issues though it's recommended to try this SSDT
+10th gen motherboards **do not** need this SSDT, NVRAM's native on these platforms.

+
+## 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 `Device (RHUB)`
+
+You should get something like the following show up:
+
+![](/images/Universal/rhub-md/rhub-path.png)
+
+From the above, we can see that the full ACPI pathing for RHUB is `PCI0.XHC.RHUB`. If it's not as clear you can search for what those device paths are for your system:
+
+* Finding the PCI path:
+  * Search `PNP0A08` (If multiple show up, use the first one)
+* Finding XHCI path
+  * Search for `XHC`, `XHCI` and `XHC1`, and yours is whichever shows up.
+
+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-RHUB.dsl](https://github.com/dortania/Getting-Started-With-ACPI/blob/master/extra-files/decompiled/SSDT-RHUB.dsl)
+
+By default, this uses `PCI0.XHC_.RHUB` for the pathing. you'll want to rename accordingly.
+
+Following the example from above, we'll be renaming it to `PCI0.XHC1.RHUB`:
+
+**Before**:
+
+```
+External (_SB_.PCI0.XHC_.RHUB, DeviceObj) <- Rename this
+
+Scope (_SB.PCI0.XHC_.RHUB) <- Rename this
+```
+
+![](/images/Universal/rhub-md/ssdt-before.png)
+
+Following the example pathing we found, the SSDT should look something like this:
+
+**After**:
+
+```
+External (_SB.PCI0.XHC1.RHUB, DeviceObj) <- Renamed
+
+Scope (_SB.PCI0.XHC1.RHUB) <- Renamed
+```

+## What this SSDT does
+
+So on 400 series motherboards, certain OEMs have broken the ACPI spec and this results in issues when booting into macOS. To fix this, we'll want to turn off the RHUB device and force macOS to manually rebuild the ports.
+
+The following platforms will require fixing:
+
+* Mobile Icelake(currently Dell and Lenovo are the 2 known with this issue)
+* Asus Z490 (Gigabyte and AsRock users are fine, whether MSI currently this is unknown)
+
+## Methods to make this SSDT
+
+For the RTC fix, there are 2 methods you can choose from:
+
+* [Prebuilt](/Universal/rhub-methods/prebuilt.md)
+* [Manual](/Universal/rhub-methods/manual.md)
