help with Dell Precision 5820 tower for Sequoia,Opencore v1.0.7

[01ttOly]

I'm at my wit's end.

It's a Dell Precision 5820 tower, C422,Intel xeon w-2135, Intel u.2 P3600 nvme, 64GB reg ram,rx5500xt.

No matter what I tried,it always freezes at EXITBS. Opencore V1.0.7

 

I have the latest BIOS V2.50.1,updated from V2.48.

The common BIOS options sure is right.

SATA:AHCI, CSM disabled, above 4g decoding  enabled, Secure boot disabled,etc.

 

Tried with platform macPro 7,1 and now iMac Pro 1,1.

 

I even tried with the EFI from Github 5820 for Ventura, freezes at EXITBS too.

 

Tried with all tweaks of config.plist, quirks options,etc with the help of AI.AI doesn't help too much.All AIs are actually learning from gurus like @Hervé @Jake Lo.

 

Would you pls take a look into my config.plist.I need to make this dell running macOS Sequoia at the moment and Tahoe in the near future.

 

thanks for anyone.have been struggling it for over 3 days.

@Hervé

 

my deepest gratitude for your guaidance.

 

I got the machine with bios 2.4.8 and updated to 2.50.1,offcial log mainly is security patches.

The github's file are more than 8 months old,didn't mention it's BIOS verison.

 

Sure I would suspect it's the BIOS, I tried github's ACPI files,then Dortania's guide's files,both failed,and decompiles the SSDTs,nothing seems wrong.But sure limited by my knowledge of ACPI,I should be wrong.

 

Waiting for your help,thanks.

I would recommend a few things to begin with:

1. startup with a minimum set of kexts as in the Github repo; you may add more once macOS boots up and you need more services/hardware supported.
2. the Github repo does stipulates that the posted EFI only works with Ventura. Did you try to install Ventura with it?
3. your set of quirks differs a lot from those enabled in the Github repo. I've not looked at your hardware in details but I would suspect that your current quirks settings is at fault here.

thanks.

1.my set of kexts are almost the same as in the Github,I would remove one CPUTscSync.kext which isn't present in the Github.

2.after failing,I did try with the Github repo and install Ventura,to no avail either,that's why I suspect it's my new BIOS.

3.What hardware details that I need to upload? By far I assume that both my new Dell BIOS implementation and my current quirks setting is at fault,but no idea where to tweak.

 

Waiting for your further help.
