Hi All,
I have a z390 designare with a 9900KS on F8 bios. My windows run very well but at the boot (gigabyte logo) during 2sec, i have this error message : "Unsupported PCH SKU, LpcDeviceId: 0xA305 ! GPIO ERROR : Incorrect GpioPad used on this chipset (Group=5, pad=257) ! Failed to write GPIO - Invalid parameter "
Do you have a idea what is it?

Thanks for your support
