Good point. Haven't ever had to swap one out. I imagine that my machine's life cycle has been short enough to avoid it (or I've just been lucky).

It doesn't happen very often that you really need to replace one - any power spike that's large enough to fry the BIOS is large enough to fry everything else on the mobo as well, so there's not much point in trying to resurrect the BIOS in those cases. Mostly, I think they get blown the way I blew mine - user error. In my case, thinking about what I was going to be doing next, instead of paying attention to the thing I was soldering at the moment ;)
