In light of the discussion about distribution of EDE, perhaps people would find it interesting that Wade Bowmer has managed to get Ensoniq EPS and VFX-SD compatible disk access working in Linux - including a script that will allow you to write an EDE disk image to a floppy:

I believe that the zero-sector patch has been merged into the Linux kernel since then. I haven't myself tested this, but it looks straightforward enough.
