A bootstrap script
Way down deep in the innards of a PC there lives a tiny control freak named the Basic Input/Output System.
And that's just the beginning.
"The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere.
It cannot get it from the operating system because the operating system is located on a hard disk, and the microprocessor cannot get to it without some instructions that tell it how."
