I have tried this with no luck.

I copied the image to my USB drive with dd.  The ERLITE did not detect the kernel (see script below).  Putting it back into my NetBSD-9/amd64 machine, it was detected as umass0 not sd0, so I had to reboot.  (How can the busses be rescanned to detect this properly?)  

Looking more carefully at the image, it seems to have an NTFS partition and a NetBSD partition defined in a GPT (see below).  However, I could not mount either to look at their contents.

In any case, this is not the solution for the ERLITE, which brings me back to the disklabel questions.  Should the kernel have to fabricate a geometry and is that a warning sign?  How can a proper disklabel be written so that the ERLITE (or now OCTEON) kernel can detect it as the root filesystem?

Thanks for any help.

Cheers,
Brook
