Gigabyte Z390 M Gaming build with working NVRAM

I’ve had problems with iStat and sleep before. That’s not what’s happening with me right now, but you might want to try without.

Mines a clean install with only istats installed and signed in to apple account. I’ll reload it again tonight.
 
So I still can't find the solution to do a factory bios reset (F4).
I made a new clear Cmos, the F9j is well cleaned :)
I put the variable 0x5C1 0x0 back to 0x1.
the cfg lock is changed from enable to disable.
When I extract this bios (after optimal settings), we can see that we find "cfg lock" in 2 different places.

by digging a little, I find 2 times internal graphics. we can see that it is on "Auto" (0x2). var name : 0x91A.
which means that I should have a display (motherboard) if I remove the graphics card. which is not the case
I'm going to set it to enable 0x1 -> set_var_3 0x91A 0x1
then disconnect my graphics card and connect to the igpu
what do you think?
but it doesn't say why the option disappeared from the bios.

All the BIOS setting should be configurable with this method. Just be careful and enter the correct settings.
 
I think I know the answer to your OEM mismatch problem. This can happen if your new bios files is a different size than your prior one. To fix it you will have to use the efiflash tool with the command
Code:
efiflash biosfilename /x \NoOemID
The reference for this advice is https://www.tweaktownforum.com/foru...gigabyte-latest-beta-bios?p=747861#post747861

Here’s some info on using efiflash.
Hi,
it works (no need to use /x \NoOemID cause this efiflash bypass the oem error) thank you. I'm now with F9l bios,
but still no igpu option in IO.
so I made a efiflash in F4, the option reappears. I select it.
then efiflash in F9l, the option is not there anymore !
can you please send me your bios? I'm going crazy.

I did mine when it was still beta. You can still get from tweaktown. I had assumed they were the same but I did not verify.


I did not mean to link directly to the file so I removed that.

I have the igpu option on the settings menu as shown here

I just updated to the latest public beta and sleep worked fine for me. I have no software installed on that drive.

I just changed out the SSDT-PLUG.aml for the one you post to restore power nap. And now I have sleep working good again.. Now just to fine tune config.plist to my setup.

Only other issue from sleep is the usb drives. When waking up from sleep I get a message (disk not ejected properly)
USB drive was plugged into the USB3 Header(Front) on motherboard.

Thank you for all your hard work.

Still having a little problem with it now staying asleep. It will go to sleep for awhile but then wakes on its own.
This is the log I pulled

It's normal for the system to wake itself to do things such as sync Messages, email, etc.

You can disable this by disabling Power Nap in System Preferences > Energy Saver.

In fact, you can also disable Wake for network access.

You can also disable proximity wake:
Code:
pmset -a proximitywake 0
 
I would also try disabling handoff if you are having sleeping problems, although that may be covered by proximity wake=0.
