What is BIOS in operating system?

The term BIOS (Basic Input/Output System) was created by Gary Kildall and first appeared in the CP/M operating system in 1975, describing the machine-specific part of CP/M loaded during boot time that interfaces directly with the hardware. (A CP/M machine usually has only a simple boot loader in its ROM.)

What is the difference between system BIOS and lead BIOS?

It is also called the System BIOS because it is responsible for the operating system being loaded in the RAM. So, it can be said that it acts as an intermediate program between the operating system and the hardware of your computer. Just like system BIOS, the BIOS of your computer is also called as lead BIOS.
