Can OS bypass the BIOS?

Thanks for the link, but it was better to fully understand the question first.

You are really something, aren't you?
I'll suggest in turn, you first do some research before asking. That way you will be able to better put your question or have it answered before having the need to post. How about that?

I don't have to be guessing what you really mean with your question when little of it makes any sense.
