Re: No ConOut(Dev) on ASUS PRIME Z590M-PLUS UEFI

I’ve booted the systems with the FreeBSD 12 live usb stick and the Ubuntu 20.04 LTS desktop live usb.

Both don’t show the required(???) ConOut/ConOutDev devices, preventing FreeBSD 13 from doing anything graphical there and falling back to serial.

It looks like the FreeBSD 12 loader tries vga textmode anyway in that case but support for that has been removed from the FreeBSD 13 loader.

Does anyone more enlightened in UEFI has a clue wether this is a valid motherboard behaviour?

This is disabled as far as I know, as all SATA/NVMe storage is available. At first I thought this might be due to the intel i9-11900T video not supported yet, but also with a GeForce GT 710 installed the video doesn’t work in UEFI mode.
