My thought is that these MSI boards need to have the OS be UEFI in order to utilize 4g encoding. That's the only difference I can see between ETHOS and SMOS is that the ETHOS drive (usb or ssd) is UEFI and not Legacy.
Has anyone else had similar issues?
I have an MSI board running Ethos right now (1 570 + 5 580's) that I can't get to boot simpleMining. It wants an EFI boot and I can't get it to see the legacy usb to even boot at all. Not sure if that is the only problem but I have yet to work it out.
