Firmware Update

I was cleaning up my system and noticed that my 10D has an outdated firmware. So, I googled the latest version and downloaded it to my cf card. It's the scariest 5 minutes of my photographic life (LOL) ever. As the progress bar slowly went up from 0% to 100%, I can't help but imagine the possibility of failure. Then it all ends up with a useless camera that's worth thousands of pesos. And *ting* Firmware Update Complete, the LCD display says.
