Hey guys, new here. i have a sony crx195e1, and i want to o/c it

so, i have this sony crx195e1 burner. i was looking for a firmware update, and i ran across something about oc’ing the drive. i have never heard of this before, so i would like to try it. the drive is quite old, so i dont care what happens, i just want to have something my computer crazy buddy doesnt! so, i see that dhc014 has a site about this, but i would like for some info on how to so this. i dont even know how to find what i have for firmware. any advice would be great. thanks!
