General Comments
In BIOS; enable "CSM" and disable "Above 4G Decoding", ArcaOS 5.0.6 then installs without any issues.

Two of the USB ports are supposed to be USB 2.0 compatible but they are not "real" USB 2.0 ports so in order to avoid problems a StarTech 4 port low profile PCI Express USB 2.0 card was installed(PEXUSB4DP). Keyboard/mouse and external USB drives work fine with this card.

Onboard NIC was correctly detected and works with E1000B.OS2. Initially there was a problem with ACPI/NIC/Interrupts but this was fixed with ACPI version 3.23.13.

Graphics, Radeon RX580, and works fine with Panorama.

Now this computer works as a multiboot, ArcaOS and Win10 on separate disks.
