BIOS

In IBM PC compatible computers, the Basic Input/Output System (BIOS), also known as the system BIOS or ROM BIOS ( /ˈbaɪ.oʊs/), is a de facto standard defining a firmware interface. The name originated from the Basic Input Output System used in the CP/M operating system (released in 1976), where the BIOS was loaded from disk, with only a small boot loader program stored in read-only memory.
