Stranger and stranger all the time.  I went right back to basics and tried 
building a basic kernel that supports only the floppy drives (/d0==/dd) 
and the drivewire drives (/x0 and /x1) using the 'mb' script on the 
drivewire example image from Cloud9.  Doesn't work.

To recap:  Using the Cloud9 HDB ROM, I can boot directly from a DW server 
running on Linux.  Everything operates correctly.  Any and all attempts at 
building a system that boots _elsewhere_ (even one where /x0==/dd!) under 
the standard ROM yet recognizes the DW volume(s) has failed.

The server appears to see a reset from the CoCo, but other than that - 
nothing.  When I try to access /x0 from the CoCo, it hangs.

What on earth am I doing wrong?  I have no trouble generating systems, 
some quite complex, that support all the rest of my hardware!
