E7280: HDMI Output and EFI fine tune

Hello,

 

I have been migrating from from a dell 5470 to a 7280. I have collected an EFI and adjusted to my machine with the OpenCore Configurator. I'm pretty happy with the congif, but I have 2 questions:

 

- I'm not so sure what is the "Firmware.scap" file on the Apple/Extentions. this is file is pretty big on my EFI foler. I have read that I can delete it and it will be regenrated. Any info on that ?

-I have no HDMI output... Any incorrect configuration on my EFI folder ?

 

Thanks In advance for your help

I had to split my EFI folder in 2 zip files.

 

Thanks

Hello Lorys,

 

well the "file - test" work like a charm, HDMI output is back. and the full touchpad feature is a dream ! Thanks

 

My model got touchscreen, with your EFI I lost it.. not event sure I want it since I'm not a big fan of it but I will try to compare with my previous EFI.

 

Thanks again

Max

Hello @Lorys89

 

I'm sorry because I'm going to ask you basic question, because I play a bit with the config.plist but I'm far from an expert..

 

-ioreg log: WellI didn't find out yet how to generate it..is this something that I can do with ioRegistry explorer ? if you tell me how I'm happy to do it :-) ( see touchscreen attachement)

-SSDT-DELL-LATITUDE-7280.zip: system doesn't boot if I put the file in ( see boot attachment). Normally I have a lot of SSDT files on that folder.

-Education: I normally udate Kexts via the tool Hackintool, should I don't do it to avoid losing your specific config ?

-Where did you put all the specific config for the model 7280, only on the file above ? 

 

Sorry for the question and thanks for your help

I'm not sure you'll get Touchscreen working in Catalina or Big Sur without some add-on software. It certainly was the case for my Skylake E7270 for which Touchscreen worked OOB up to Mojave. @Maxd13, your SysInfo screenshot seems to show you've changed your SMBIOS from MBP (which would have been correct) to that of an iMac (which would be incorrect). Is that the case?
