If you attempt to update the OBP firmware on a Sunfire v880 and get
them message:

** ERROR: system security set: system firmware was not modified

even though the keyswitch is set correctly and the jumper is set to
write enable, then you need to set the OBP paramater "security-mode"
to "none" not 255 or any other value.
