I don't know if anyone else has this problem, but morphos 3.20 won't boot. I've got a dual gfxcard setup. Radeon rx550 and Firemv 2250 1x. This setup works beautifully with morhos 3.19. But with morphos 3.20 I get no monitor output on the firemv.
I downloaded the hdimg. Wrote it to an usb stick with rawdisk, and then bootet from the usbtick with - usb reset -bootmorphos
It shows no ouput on the firemv. The same procedure works with the 319 hdimg.
