# Pre-Built SSDTs

- Power Management
- Embedded Controllers
- Trackpad
- Backlight
- System Clock(AWAC)
- NVRAM(PMC)

This is mainly for users who are having troubles either compiling, decompiling or understanding the overal process of ACPI. The main reasons you'd want to avoid is for the following:

- Slowing down the boot process
  - Mainly because these SSDTs have to go through every possible pathing
  - Fun fact: the prebuilt SSDT-EC-DESKTOP is 42 times larger than making the file yourself
- Doesn't always work
  - The SSDTs provided can only handle so many situations, and some may in fact not work
  - Mainly seen with SSDT-AWAC, as it assumes there is a way the RTC can be easily enabled
- Teaches nothing
  - This is the biggest issue as you have no real idea on how to troubleshoot or how to make these files down the line

Please refer to Choosing the SSDTs page for which your system needs.

## Power Management

For Haswell and newer:

- SSDT-PLUG-DRTNIA

For Ivy Bridge and older, see the Optimizing Power Management page. This will be done after install. AMD CPU users do not need any SSDTs for power management.

## Embedded Controllers

For desktops:

- SSDT-EC-USBX-DESKTOP
  - For Skylake and newer and all AMD systems.
- SSDT-EC-DESKTOP
  - For Broadwell and older.

For laptops:

- SSDT-EC-USBX-LAPTOP
  - For Skylake and newer.
- SSDT-EC-LAPTOP
  - For Broadwell and older.

## Trackpad

Used for enabling Windows only features in macOS, do note that the below patches will more than likely break Windows booting via OpenCore. I highly encourage you to make one yourself to prevent any issues down the line: Trackpad GPI0

- SSDT-XOSI

- XOSI-Rename.plist

  - Note you'll need to add this into your config.plist under `ACPI -> Patch`:

Comment | String | Change _OSI to XOSI
--- | --- | ---
Enabled | Boolean | YES
Count | Number | 0
Limit | Number | 0
Find | Data | 5f4f5349
Replace | Data | 584f5349

## Backlight

For laptops and all-in-one desktops, fixies brightness control support

- SSDT-PNLF
  - For most users.
- SSDT-PNLF-CFL
  - For Coffee Lake and newer.

## System Clock(AWAC)

Mainly needed for newer systems running AWAC based system clocks, mainly relavant for Z390 and newer(Gigabyte and AsRock however did backport it to Z370 with a BIOS update)

- SSDT-AWAC

The biggest issue with this prebuilt is that we're just guessing you both have an AWAC clock and that it can be turned off, I highly encourage you to make one yourself to really know whether you both need this and if it's going to work: AWAC vs RTC

## NVRAM(PMC)

Needed to bring back NVRAM support for Z390 and newer, DO NOT USE ON Z370 or older

Note: Desktop Z490 boards seem to not need this, though if you're having NVRAM issues you can try this SSDT.

- SSDT-PMC

Reminder only the following need this SSDT:

- B360
- B365
- H310
- H370
- Z390
- 400 series (Comet Lake)
- 495 series (Icelake)

## USB(RHUB)

Needed for 10th gen CPUs, Gigabyte and AsRock motherboards don't need this

- SSDT-RHUB.aml
