​

procedure

Initialize HDD​

Opencore Starts with USB.​

The monitor is lost in the middle of rebooting 4 times after installation​

Since it is the worst pattern, remove the HDMI monitor terminal and insert it again to restore the screen.​

After installation, the monitor is lost during the startup of Big Sur​

This also shows the screen by inserting and removing the HDMI terminal.​

current situation
　No sound.
　I can't see wifi. BT is OK. ‥
　Replaced with a DELL1560 card. ‥
　The monitor settings include opencore materials,
　I am lost when I sleep.

　It's painful that there is no sound

enjoy

Thank you
I don't have it now
Yes, that's right, and my setup was a mistake.

 

[gstream]

Is it safe to use the attached EFI? Did you have a chance to resolve the issues?

 

[oldmacharu]

The attached EFI is for experimentation
There was no sound in my work.
(This is a setting error, so please correct it.)
WIFI 1560 cannot be connected.
(The problem has not been identified.)
Currently, I don't have this machine at hand.
safety? The PC will not be broken.

have fun.

Hello, I have this PC with an i5 7500t, you will have the EFI or some tutorial to be able to start it, since with the efi that you put me I do not have audio among other things.

SLEEP NG

iMac18.1 didn't make any sound
iMac 18.2 made a sound, but the screen turned pink
Sound and screen are normal on iMacmini8.1.
If you use it without SLEEP, there is no problem.

I've recently acquired a 7050 Micro that has i5-7600T, 8GB ram, 512GB M.2 SSD, Intel HD 630 graphic, and ALC3234 audio.

Are there any updates on solving the sleep issue with the above EFI? I'd like to run Catalina on it.

 

[oldmacharu]

The micro I used is Intel wifi, and the sleep is wifi is not supported by Intel
There is a possibility if you do not use wifi.
please try it.
