Is the RX50 drive supported *after* NetBSD is installed?  I just wanted
to try making RX50 NetBSD boot/miniroot diskettes for others without a 
means of creating them.  But when I try to dd to the raw floppy device
(/dev/rra2c in this case), I get a bunch of 

	uda0: unit 2 not configured, blah blah blah

followed by

	dd: /dev/rra2c: Input/output error

The light on the floppy does flicker briefly.

I see the following note in the installation README:
  [sic]
  Supported install media is TK50 tape and RX33/RX50 floppy.  If 
  you do initial installation from floppy then you need a way to load 
  the rest of the system, like tape or ethernet. 

which seems to suggest that the floppy isn't really supported beyond
booting the system.
