need original bios for sony FZ21Z

[profchaos1981]

I have vaio fz21z and I made a mistake of buying a trird party battery for it.These batteries have a cd that flashes original bios in order to work..as a result original sony batteries don’t work properly. I m searching for couple of weeks through net but I cant find a thing. It would be very helpful to sent me the original rom to reflash my bios and the way to flash it.Thanks for reading this and I hope to give me some help.
