Slice Posted May 30, 2021 Share Posted May 30, 2021 You probably need a patch DellSMBIOSPatch provided by Clover. It is for Dell laptops with skylake. 1 Quote Link to comment Share on other sites More sharing options...

I am using VoodooPS2_for_Alps which contains Controller, Keyboard and Touchpad drivers. I need no SSDT. I also using DSDT fixes by Clover.

Slice Posted May 31, 2021 Share Posted May 31, 2021 I have no right EFI folder for your notebook. I can propose you to use BDU for creating USB stick with EFI folder more or less universal. Then I can help you to change somthing if you'll tell me what is happen at start and will provide debug log. Quote Link to comment Share on other sites More sharing options...
