The OS translates code into Machine, assembly, binary etc but how does that actually tell the chip set which pins to fire, which to close, etc? Or which circuits on the board(s) to open, close, etc?
Especially considering the OS exists IN THE HARDWARE once the ISO is loaded???

At the fundamental level, it's all based on voltage.
Machine communication - binary (0's and 1's)
Circuit communication - voltage
High voltage - 1
Low voltage - 0
Sure you can find detailed explanations on the web
