If it works similar to the Sun Fire v20z (newisys 2100e) the flash
upgrade mechanism in the SP is pretty useless as it only works when you
did not mess up the bios of the machine. What this does is tell the
bios: "Please update yourself, here's the data"

Doing the port does not sound too hard though, given you have a 
local machine.
