The concept of BIOS originated in the 1970s when personal computers were becoming more common. At the time, computers used various hardware components from different manufacturers, and there was a need for a standardized way to communicate with and initialize these components during the boot process.
In response to this need, engineers and programmers developed the BIOS as a fundamental part of the computer's firmware. The IBM Personal Computer (IBM PC), released in 1981, played a significant role in popularizing the BIOS concept and establishing it as an industry standard.
Many individuals contributed to the development and evolution of the BIOS over the years, but it's challenging to pinpoint a single person as the inventor of BIOS. Instead, it represents the collective efforts of numerous engineers, programmers, and hardware specialists who worked together to create this essential component of personal computer systems.
