any know how to downgrade OPENCORE 0.7.9 to 0.7.8????

Same as for upgrading: Replace BOOT/BOOTx86.efi, OC/Drivers/OpenRuntime.efi (+OpenCanopy.efi) and OC/OpenCore.efi by the new (or, here, old) versions. Then, adapt the config.plist to the appropriate syntax or copy and paste settings from config.plist to the appropriate Sample.plist.

The question is: Why would you want to downgrade?

 

At which point are you now, and which which settings?

@metacollin, who gave the first explanation on CPU wrapping, had a X11DAi working with two Xeon Scalable, so dual processor is possible. But we have to find out how…

Good work!

Have you tried PlatformInfo>UpdateSmbios:True to solve the firmware update issue?

 

The issue with earlier OSes is more puzzling… We may not have found the right combination of quirks. Or some device could be unsupported—the i210 NICs being prime suspects.

what is the next step?????

I wish I knew…

It seems you'll need a lot of patience, perseverance, and possibly some luck. As next step, you may try to disable non-essential devices in BIOS (NIC, CPU 2) and see if it helps. Try different OS, with the most verbose settings to find out where the issue is.

 

A seller on eBay US offers this motherboard "for Hackintosh" with an EFI of his making. So it must be possible.

It's quite easy to find. The seller goes by the name 'superchief9'.

If you're desperate, that may be a way to get one (or two!) machines running, but you would have to rely on the seller for future support if he doesn't like his EFI being shared on forums.
