Did any of the Ethernet network cards A2065, Ariadne Z-II, A4066, X-Surf support booting from the network out of the box?, or if the Amiga could support that at all?
Preferably per file style, but simulated block-disc may work too.
I'm not sure that the Amiga could, I mean maybe, possibly using NetBSD as your OS and it pre rigged to run that way.
But it'd be a hell of a job to get it going even if the hardware is physically capable.
