I can boot the system fine when there is no volume configured, but then it appears to be diskless. As soon as I configure volumes, the kernel throws an error message very early on, and as the system immediately reboots, I can’t even say what the message contains. 

If gotten the system to run. It turns out you can switch the on-board controller from its RAID mode to be just a SATA AHCI controller. With that setting, installing dragonflybsd was actually straightforward. I’m still mostly fond of the system; it’s a neat little package for a very low price.
