E5590: No touchpad/mouse (Catalina with OpenCore))

Recommended Posts

It seems I am back to opencore.
I managed to get a triple boot (Windows 10, Arch Linux & Mac Os Big sur) going quite easy, but I still dont have a working touch.

I followed https://voodooi2c.github.io/#GPIO Pinning/GPIO Pinning but I dont understand how to create the patch in the end?
Do i have to modify the DSDT itself? Since with opencore the DSDT is used from system, I dont have option to add "custom" one

  Name (SBFG, ResourceTemplate ()
        GpioInt (Level, ActiveLow, ExclusiveAndWake, PullDefault, 0x0000,
            "\\_SB.PCI0.GPI0", 0x00, ResourceConsumer, ,
            {   // Pin list

Should be the code to have in my DSDT instead of Pin list 0x0000 which it says now, but I am clueless.


Any ideas? Thanks!
