Your awnser:

The BIOS system chip was designed purely on mathmatics. It is the main input/output controler in your system, as it's name inplies.

imagine this, your CPU was made of thousands of light switches and depending on which ones were flicked on, you could always generate a predictible mathmatical equasion based on that. When thinking about micro computer fundementals, you should remember that one game on the "Price is Right" where the player drops the token down the slanted pin board to land in a money spot, but think of this method as being predictable such as in computer design.

Before dos or any compiled language (where dos doesn't matter in your programming question) there was assemboly which is more the less "binary" in a form humans can understand. The assemboly language for the most part is nothing more than crap written in HEX, which is just a short hand form of binary.

read several books on assemboly and take several months to digest it, and then you'll understand half of nothing that I do. puters at the machine level are so damn complicated.... The only way to ever being able to understand is to purse it always, asking us will never make you understand...

To damn hard to explain, i'm going back to my beer sluggin' now....
