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!
