I got 7390 2-in-1  working EFI Ventura 13.0.1

Latitude 7390 2 in 1: BIOS 1.26.0, Core i7-8650U @1.90GHz, 16GB DDR3-2133, Intel UHD 620, 1920x1080 Touch

 

I used the EFI from below, thanks to Jazzo for sharing it.

I have thunderbolt dell docking working for display only with keyboard, touchpad and touchpad buttons working.

 

this is my first post, so sorry for any error and if i did not followed forum rules. Moderator, please accommodate and guide me to right direction.

 

I am unable to load my EFI due to attachment file size limit.

I see you include CPUFriendDataProvider, what CPU is this customized for?

Are you seeking for help with something or it's just informational?

If informational, thanks for the upload.

Please post IOReg file with IORegistryExplorer.app for review

Graphics settings look a bit odd to me for a Kaby Lake U/Kaby Lake R laptop with HD 620/UHD 620 graphics (i.e. 7th or 8th gen)... For clarification, you should add your system's specs in signature or post them in your introductory post (we don't have crystal balls, sorry).

Never seen the need to change built-in LCD connector's pipe for instance.

 

The recommend settings for an 8th gen Kaby Lake R laptop with UHD 620 graphics used to be:

  • framebuffer layout 0x591b0000 (I used 0x59160000 for Mojave and 0x59160009 for Catalina on my 8th gen KBL R Latitude 7490), 0x87c00000 being for Amber Lake laptops (Dortania's documentation says otherwise but...)
  • fake iGPU id 0x5916

See the WEG user manual.

It's worth noting that, on the 7490, HDMI output required connector con1 to be configured (i.e. patched) as follows:

01051200 00080000 87010000

The patch therefore varies according to the FB used. I see no reason why things would be different on an 8th gen 7390.
