Finally I had time to make some tests. I started with your latest EFI folder that includes the latest configuration. I only changed SMBIOS to iMac19,1 and the machine gets KP when booting, so I tried leaving the SMBIOS as is, Macmini8,1, and macOS works very well completely, USB ports included. For the moment I am going to stuck with it. Much better PM than mine, created with default Dortania files, now the CPU wattage is much much lower!! Great work @deeveedee, thank you really much!

Only have one thing to fix, but don't know how to achieve it. Now my Windows 10 OS on the separate NVMe drive doesn't boot using OpenCore. Can you give me a hint in order to fix it?

Thank you!

Awesome - that's great news! I haven't experimented with iMac19,1, but it's possible that you would need to "start from scratch" for USB and Graphics patching before making the SMBIOS MacModel switch. In other words, before switching SMBIOS, you might need to delete your USB patch (USBPorts.kext or USBInjectAll.kext / SSDT-UIAC.aml) and enable XHC Port Limit. Then use Hackintool to find the correct USB patch (see here). Then remove your Graphics Device Properties and start over with Device Property experimentation to find the correct WEG properties. Start with just USB to see if that does the trick.

Unfortunately, I won't be much help with booting other OSes with OC. @Carstimann posted a potential OC dual-boot solution here. I have not reviewed / tried it and am still content to press F9 in the rare instances that I want to boot Windows. I have not reviewed / tested my ACPI patches (SSDTs) for Windows (although some already have the "Darwin" conditionals) and I haven't edited the OC config.plist for Windows.

I have upgraded my HP EliteDesk 800 G4 Mini BIOS to the recently released 02.14.01 Rev.A. All appears to be well. Be patient with this BIOS update and don't touch your PC until the update is finished. There may be long, awkward pauses of inactivity (even pauses where it appears that the unit is completely off / dark and there are no indicator lights).

That is pretty strange: I have had no problem booting windows off of another SSD through OC and I have also tested moving the SMBIOS to an iMac19,1 and had no problems doing it (though I found no benefit so I reverted).
I also found no difference to speak of between in power management between the CPUfriend solution you had in your EFI and after it's removal allowing MacOs to manage it itself.
The final step for me was done today where I moved the ACPI implementation from the vanilla OC to @deeveedee's more customized one and I am still testing this. So far, no difference to speak of. I did a USB remap and the map is the same, I only added the corresponding connector types on my version. It is just so lucky for us that these machines have exactly 15 USB ports to be represented. (3 front x2, 4 rear x2, M.2 internal x1).

Been trying the watch unlock but that's for another thread...

That's encouraging.

@chanquete69 , if you want to post your EFI that's causing your troubles, we have enough eyes looking at it that we might be able to help you. When you post your EFI, please confirm that your BIOS settings match those described in the PDF document attached to Post #1.

Hi have just tried with the current EFI folder with latest changes to USBPorts, and deleted USBX. Same panic:

Looks to me like we've forgotten about some of the things we already discussed. The EFI you posted includes graphics DeviceProperties that specify framebuffer-conX-type = DigitalDVI. You previously indicated that your graphics ports are DP and your displays are DP (no graphics adapters) so you should be using framebuffer-conX-type = DP (0x0400). Please read Known Issues and look specifically for DVI and BusID comments. You will need to create your own graphics Device Properties. Your system has display properties that are different from the specs in Post #1 of this thread, so you need to customize your config.plist for your own system. This may include some or all of the following:
  1. AAPL,ig-platform-id: My system requires <0000923E> as explained here. You may need <07009B3E>
  2. framebuffer-con0-type: My system requires <04000000> because I am using DP->DVI adapters. Your system will require <00040000> because you are using DP with no adapters.
  3. framebuffer-conX-busid: My system requires <01000000> which is appropriate for DigitalDVI. According to this, BusID 1 is not valid for port type DP, so you will need to change your framebuffer-conX-busids to one valid for DP ports (BusIDs 0x02, 0x04, 0x05, 0x06 are permitted according to this).

I didn't look beyond that. Proper framebuffer patching is tedious - the most difficult part of this build for me. I can't spare you the pain. You will need to experiment to find the correct framebuffer patching for your system.

Thank you for your response. I made the changes in the framebuffer you suggested, in fact I copied them since my own configuration where I have iMac19,1 SMBIOS working and the same problem appears, I have KP. I attach them again with the changes to this post. As I said, MM8,1 works really well for me, I am trying only the change to iMac19,1 to see if Power Management would be better for 9th Gen Intel Processor, but I will probably stuck with your stock EFI.

I hope this weekend will have time to completely format the Elitedesk to make a Big Sur clean install, so I will probably stuck with the Macmini8,1 SMBIOS.

Thank you very much for your work deeveedee!

Not sure I completely understand, but if MM8,1 works, that's great! Note that in the most recent config.plist you posted, you're still trying to use framebuffer-con0-busid=1 with framebuffer-con0-type=0x0400 which according to this is invalid.

Yes, without touching anything from your stock EFI, it works flawless (also with the bad values of framebuffer, dind’t touch any of them and it works). The kernel panic appears only if I change SMBIOS to iMac19,1. I am going to change the connection type now to see if it works.
