If VoodooGPIO isn't attached, then you may need to modify the `_STA` method in the `GPI0` device. In that case, you will need to find the GPI0 device in ACPI.
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).

There are various checks for many different versions of Windows, but there is no check for `Darwin` (which Apple's ACPI usually checks for). We generally want to set `OSYS` to the value for the latest version of Windows in order to enable the most features. In this case, the latest version of Windows is "Windows 2015", or [Windows 10](https://docs.microsoft.com/en-us/windows-hardware/drivers/acpi/winacpi-osi#_osi-strings-for-windows-operating-systems). This means that we should set OSYS to `0x07DF`. Notice that this value is greater than the `OSYS < 0x07DC` value being checked for earlier, which means that the check in LSTA should return `0x0F` now.
The best way to patch these checks is to use _OSI to XOSI with SSDT-XOSI, or to set the OSYS value just within the scope of the I2CX device. Attempting to set OSYS directly generally fails as _INI sets a default value which will override whatever value you set.

### Note:
Windows will also return true for checks of earlier versions of the OS. For example, Windows 7 would return true for "Windows 2000" through "Windows 2009", but not any version after. This is important as some features are only enabled in earlier Windows checks. For example, `WNTF = 0x01` allows DYTC thermal management to work on newer Thinkpads, though this only gets set in the check for "Windows 2001". You will need to check your own DSDT and see what values it sets and where they are used. At this point, you should [compiling the SSDT](/Manual/compile.md) and see if the trackpad works.
