I have understood it like this:
A BIOS is basically a ROM memory. It is read by the CPU of the PC to bring up the first instructions how to do a test of the hardware on the motherboard, aka POST. Then it brings up instructions so the CPU is able to access the boot sector of the harddrive (typically of a homecomputer), and then bring in the operationg system. Now it can leave the control to the user and the computer is operative.
Am I right so far? (I have follow up questions if I have got this part right.)
I hope that this Science Forum is the right forum for this kind of question. I know that there are a bunch of skilled people here, so I think that I will get fruitful and accurate answers.
