It should be quite very possible to make a virus that embedded it self
in Flash ROM. but it should not be possible for it to actually destroy
the rom. just overwrite it. So yes.. the way to get rid of a virus like
that should be to download a ROM from TI and update your calc.. (and of
course reset and erase every erasable memory there is..  just to be sure
it isn't hiding somewhere..)
