Hello, With a lot of help and references, I was able to make an EFI that is working perfectly for this 4900hs based machine, except for the trackpad.
I have tried everything. Windows identifies it as an ELAN1201. I have tried every version of the VoodooI2C kexts including the 2.9 prerelease and the ones compiled by Nooted etc.
I have also tried the Voodoo ELAN driver, no result.
I have tried dumping the DSDT and generating SSDT-XOSI and patching, forcing pinning, still nothing.
The device shows up in the GPIO but I do not have an SSDT-GPIO because I really don’t know how to assemble that file.
Can someone help with this please? I want to release this EFI onto GitHub but wouldn’t if the trackpad doesn’t work.
