- Acronym for basic input/output system. A set of indispensable software routines that enable a computer to boot itself. It has the code necessary to control all peripherals and perform other functions, such as testing, and is generally stored on a ROM chip so that disk failures do not disable it. Currently, it is usually contained in a flash memory chip, and is typically copied to the RAM at startup, as RAM is faster. Also called system BIOS (1).
