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.
