BIOS (, BY-oss, -ohss an acronym for Basic Input/Output System and also known as the System BIOS, ROM BIOS or PC BIOS) is firmware used to perform hardware initialization during the booting process (power-on startup), and to provide runtime services for operating systems and programs The BIOS firmware comes pre-installed on a personal computer's system board, and it is the first software to run when powered on The name originates from the Basic Input/Output System used in the CP/M operating system in 1975 The BIOS originally proprietary to the IBM PC has been reverse engineered by some companies (such as Phoenix Technologies) looking to create compatible systems
