I can gather that the check on this laptop checks if you have Windows 8.1 or above, and if you do, the touchpad will be enabled and allow successful installation of the HID Event Filter Driver, and thus, the Serial IO drivers. If you have Windows 7, the check will fail and disable the touchpad entirely, meaning Windows 7 won't know it exists, and one of two things will happen when you try to install the HID Event Filter driver: 1. The setup.exe will tell you your computer doesn't meet the requirements (This computer does not meet the minimum requirements for installing this software), which is expected as the OS, and thus the app, do not know that the touchpad exists, or 2. you get a 7E BSOD with IntelHidEventFilter.sys identified in the stop screen when you try to install it over a HID driver from an external device, like USB Wireless Mouse.
I'm still working on deciphering this. Basically, if the DSDT table is extracted, we can modify the check so that Windows 7 will pass and allow the touchpad to be seen within the OS, and allow it to function after installing the aforementioned drivers. The way to do this is commonly used for Hackintosh installs as Macintosh will fail the check no matter the version, meaning you'd have to edit the check so that Darwin (Macintosh) pass and allow the touchpad to work under it; since I'm not dealing with Hackintosh, we just have to adapt the tutorial for Windows use.
I'll report back later.
Dump your ACPI tables with acpidump from iASL and send them in a zip. Changing _OSI values to allow unsupported OSes is easy enough. Then the modified table will have to be injected with something like OpenCore which can be used for Windows as well.
