Also you may want to try 'rz(0,1,0)netbsd' at the Boot: prompt after
it fails..  (Sounds strange, but it worked for me before)

Could you give me the output of each of the following: (at the >> prompt)

	printenv

	boot -f rz(0,1,0)

	boot -f rz(0,1,0)foobar

What method did you use to write the bootblock and miniroot on to the
disk?
