Perhaps I should have been clearer, for the benefit of anyone else who
tries.  The instructions that came with the BBG claim that it will show
up as a disk and that one can open the on-board web-site documents
directly as files on that disk.  The instructions also claim it will
present a USB network device (presumedly "cdce") and one may access it
thusly.  While the Linux distribution configures a "usb0" network
interface, it does not show up on the NetBSD host when the board has
booted.

Then again, the instructions probably assume one is using redmondOS on
their host, so all bets are off.

Yes, but my expectation and preference is to boot it over the network
and operate as a diskless station.  I do not yet have a microSD card
available.

Yes.  This is the eMMC device on the board but according to the BBG
description/specification it should be 4096MB, not 1024MB.

That is obvious but as above I don't have one yet.
