Bios is a firmware used to perform hardware initialization during booting process and to provide runtime services for operating systems and programs. The name originated from basic input and output system.
Currently, bios in modern system not only initializes but also test the system hardware components and loads the bootloader from a memory device. Most bios these days are designed to work with a specific laptop. So by inference two laptops with varying bios models cannot be interswitched.
