The value OSYS, stores information about the current OS running. We will want to look for any place in which OSYS is set (OSYS = 0x07DC for example). In this DSDT, this is set under \_SB.PCI0._INI as shown below:

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 highest possible value to enable the most features. In this case, the highest value is set when the version of Windows is "Windows 2015", or Windows 10 (opens new window). This means that we should set OSYS to 0x07DF. Notice that this value is greater than 0x07DC, which is the value that was checked for earlier. If we set OSYS to 0x07DF, then the check in LSTA should return 0x0F.

The best way to patch these checks is to use _OSI to XOSI with SSDT-XOSI. You can also set OSYS within the scope of the I2C device, though this may not always work (The above example would not work here as LSTA is not within the scope of the I2C device).

# Create OSYS Variable Under I2C Scope

You will need to find the device path where OSYS is checked, then create a new OSYS variable within that scope. This will only change OSYS for devices under this scope, which can allow for finer control over what is enabled. Note that in the example above, LSTA exists under \_SB.PCI0.LSTA, meaning that both \_SB.PCI0._INI and \_SB.PCI0.LSTA will control the same OSYS variable. If this is the case, this method will not work.

If (_OSI("Darwin")) {
     Scope (\_SB.PCI0.I2C0) { // I2C0 scope
         Name (OSYS, 0x7DF)
     }

Multiple Windows Versions

Windows will also return true for checks of earlier versions of Windows. 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, DYTC thermal management on newer ThinkPads is only enabled 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 and see if the trackpad works.

# Further Setup

If you need further help getting your trackpad to work, then the best place to look is VoodooI2C's readme (opens new window)

# 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 wrap up:
