FE11S optical drive driver upgrade

[moebius]

hi there.

i have a question regarding the driver update on the vaio link web page. it says that it is intended for the Matsushita UJ-841model.

i have a fe11s with a Matsushita UJ-841S. should i upgrade my driver or does this "S" extension correspond to another version of the optical drive which doesn't need to be upgraded?

thanx in advance,
nikos.
