I had the same problem with some UltraSPARCs. I pluged the NVRAMS into
a SS5, i.e. a sun4m pizza box. At POST it complained about an invalid
NVRAM and droped to OBP. I did a "set-defaults", mounted the NVRAM in
the sun4u machine, power on, "invalid NVRAM" and "set-defaults" again.
This erased the password and reset OBP variables, but the host-ID and
MAC address where not touched.
