Hi
It would be awesome to run ArcaOS on that board.
NVMe will not work, but I guess that with a SATA HDD that issue will be solved. It would be cool to find out if the M.2 port is one fo does dual that supports NVMe and SATA. If so, maybe a SATA M.2 storage card may work
I have some doubts about ArcaOS UEFI experimental support. For what I see it is working to boot ArcaOS from the HDD (once it is installed), but I have some doubts about booting the USB Flash installer. It seems that the UEFI mode also applies to an OS Botting from a USB Flash/pen drive, so I'm not sure if the board does not have CSM support, if it will ever boot the USB flash ArcaOS installer. I haven't tried a DVD install yet. Any thoughts are welcome.
Regards
