The tric is to use a file (rasp) and carefully file down from the top
of the chip until you reach the battery. But do this only in the corner
where the battery is located. At least on the Sun NVRAM chips the top
of the battery is +. There goes a wire down from the top of the batery
to the chip. Carefully prepare this wire out of the resin with a hand
milling tool ("Dremel"). Cut the wire from the top of the batrery,
solder an extension wire to it and + of the new batery to the other
end. Solder - of the new battery to a wire and the other end of it to
the GND pin of the chip. I.e.: Do not connect to - of the old battery.
It is buried too deep into the resin.
