Gigabyte Z390 M Gaming build with working NVRAM

[cmert]

Yes. I did disable it, but problem was something else.

My bad, I was skipping mounting and copying EFI Folder to USB sticks folder step...

I did that and the system booted, everything seems to work...

I'm testing the system... trying to connect my camera for tethered shooting...



Thanks for detailed guide...

I didn't touch anything on your EFI, everything is working: USBs, Fenvi WiFi & Bluetooth...

I think I have to tweak some fixes and graphics driver of my system...
I have an RX570 installed.

Do you see anything that I have to change ??

Just generate and fill in Serial, Board Serial, and UUID.

OK, I will add those. How about boot arguments, are all necessary? My older hack with Mojave had only 3 I think...

And how can I add graphics card info?

Leave the boot args. Those EFIs are well tested and they work.

To add graphics info, see bottom of post #3. Look for "How to Populate System Information > PCI".

OK. I didn't touch them.

I've checked post #3, downloaded Plist Pro, opened up my exported pcidevices.plist file, open it in Plist Pro, but can't find the info you wrote on that post. Where's my mistake?

First is my screenshot of pcidevices.plist file...

Thank you for your time...

Copy all those "Properties" and replace what's in config.plist > Device > Properties.

Look for the device path of your video card and you can edit the "model" field to say anything you like. It's all just cosmetic so you can call it an "RTX 3080" if you like.

I think I did it, for the system info my cpu is i5 8400, 32gb 3000mhz ram, what should I select for model ? 18.2 or Macpro1 ??

Please see post #3 for info on which system definition to use. It's up to you...

Should I use iMacPro1,1 or iMac19,1 system definition?
iMacPro1,1 will allow for full working DRM but Sidecar will not work.
iMac19,1 will allow for Sidecar to work but DRM may or may not work. Please see here for possible DRM workarounds. I have no experience with these workarounds and won't be of any help.
Personally, I've been on iMacPro1,1 for quite a long time and it has worked extremely well.

*Note: If you need to boot High Sierra or older, you may need to use iMac18,1 system definition.


you must be referring to this,
yes I know but I was using 18.2 before and it had no issues, since my cpu is i5 8400 that's why I ask to use more likely system definition, am I wrong ?
