The efi.config.plist was the active config.plist at the time the ioreg was run.

Post your whole /EFI/CLOVER folder.

Post your whole /EFI/CLOVER folder.

Here is the clover folder from my EFI partition.

Here is the clover folder from my EFI partition.

Please debug using following those steps:
1/ Move CLOVER folder from EFI to Desktop
2/ Copy CLOVER folder from USB to EFI. Restart (I think you can boot)
3/ Overwrite config.plist from desktop to EFI. Restart
4/ Overwrite kexts folder from desktop to EFI. Restart
5/ Overwrite ACPI folder from desktop to EFI. Restart

Step 3 4 5 can be swapped when you can't boot anymore.

Tell me the best combination that you can get.

Seems like DSDT problem.

Re-extract/re-patch DSDT:
- remove all files from EFI/Clover/ACPI/origin on your USB and HDD/EFI.
- hit F4 at Clover bootloader
- use ProBook Installer CE to re-patch DSDT

Remove also origin files from HDD. I don't know where PBI-CI grabs the files from (I do my DSDT patching manually). You have to be certain you're getting a clean extract.

You might want to learn about how to patch manually, as that may be your next step (patches little at a time, so you can determine which one [if any] are causing the problem).

Ok I have a display! So I did the repatch; removed all the ACPI/origin file on the usb and the EFI partition. I then ran PBI again. On the reboot I had a display on my LCD.

Thank you all for the assistance, and helping me learn a bit more about this process!
