Humanate Posted June 6, 2020 Share Posted June 6, 2020 Hi all As per title, my Gigabyte Z390M Gaming does not have the option to disable serial port in BIOS versions F8 + and I don't want to use older version Can anyone help guide me through disabling the serial port with another method, I gather it's possible with an SSDT but I am not experienced with those. If anyone can help me I will be most grateful, I'm not a total noob but just need to be pointed along the right path Many thanks in anticipation Link to comment https://www.insanelymac.com/forum/topic/344092-help-request-z390mg-disable-serial-port-not-poss-in-bios/ Share on other sites More sharing options...

Rather than replacing the whole EFI, is it the DSDT.aml in ACPI/Patched that will disable serial port? Can I add the DSDT to my existing EFI? Just easier with SMBIOS serial numbers etc. Would that work or other changes needed?

I am keen to understand the processes though rather than copy paste. Is it the dsdt that will disable the serial port or is there something else that’s needed also? thanks for your patience and helping me to understand more Link to comment https://www.insanelymac.com/forum/topic/344092-help-request-z390mg-disable-serial-port-not-poss-in-bios/#findComment-2725237 Share on other sites More sharing options...

I think I'll have to stick with Clover for now then as I need dual boot. I added the DSDT but not working and I think this may be as I've updated the mobo BIOS since I first spoke to you (it was working on the old BIOS). I used the RunMe app again and it's attached, for some reason IOReg wouldn't save so I saved manually and added to the Send Me folder. The DSDT you supplied did work on the old BIOS so I hope it's the new BIOS that's the issue and can be fixed with a new DSDT? Sorry to be a pain!
