Just to throw out a friendly warning, I flashed my HP 8250i cd-rw which had never made a coaster, and after turning it to a 10x4x32, I could still never burn faster then 4x successfully. After about a weeks time, I couldn;t burn right at all. I bought a new HP from work for dirt cheap, 10x again, and it burns fine. In closing, just be careful, as you often times can't go back.
